NEW QUESTION # 22
A company with multiple branch offices wants a connectivity model to meet its network architecture requirements. The company focuses on ensuring low latency and efficient routing for its critical business applications. Which connectivity model meets these requirements?

  • A. star topology with internet-based VPN connections and static routing
  • B. point-to-point topology using dedicated leased lines and static routing
  • C. fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol
  • D. hub-and-spoke topology with SD-WAN technology, using dynamic routing and OSPF as the routing protocol

Answer: C


NEW QUESTION # 23


Refer to the exhibits. An engineer must redistribute only the 10.0.10.0/24 network into BGP to connect an on-premises network to a public cloud provider. These routes are currently redistributed:

Which command is missing on router R2?

  • A. redistribute ospf 1 match internal
  • B. neighbor 10.0.10.0/24 remote-as 100
  • C. neighbor 10.0.10.2 remote-as 100
  • D. redistribute ospf 1 match external

Answer: D

Explanation:
The command redistribute ospf 1 match external is missing on router R2. This command is needed to redistribute only the external OSPF routes into BGP. The external OSPF routes are those that are learned from another routing protocol or redistributed into OSPF. In this case, the 10.0.10.0/24 network is an external OSPF route, as it is redistributed from EIGRP into OSPF on router R1. The other commands are either already present or not relevant for this scenario.

NEW QUESTION # 24
Refer to the exhibit.

Drag and drop the steps from the left onto the order on the right to configure a site-to-site VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS).

Answer:

Explanation:

Explanation:
Step 1 = Create a Customer Gateway (CGW) in AWS. Step 2 = Create a Virtual Private Gateway (VGW) in AWS. Step 3 = Create a site-to-site VPN connection in AWS. Step 4 = Configure the IOS XE router with the required IPsec VPN parameters and routing settings. Step 5 = Verify and test the VPN connection.
The process of configuring a site-to-site VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS) involves several steps12.
Create a Customer Gateway (CGW) in AWS: This is the first step where you define the public IP address of your on-premises Cisco IOS XE router in AWS1.
Create a Virtual Private Gateway (VGW) in AWS: This involves creating a VGW and attaching it to the VPC in AWS1.
Create a site-to-site VPN connection in AWS: After setting up the CGW and VGW, you then create a site-to-site VPN connection in AWS. This involves specifying the CGW, VGW, and the static IP prefixes for your on-premises network1.
Configure the IOS XE router with the required IPsec VPN parameters and routing settings: After the AWS side is set up, you configure the on-premises Cisco IOS XE router with the required IPsec VPN parameters and routing settings2.
Verify and test the VPN connection: Finally, you verify and test the VPN connection to ensure that it is working correctly12.

NEW QUESTION # 25
An engineer must edit the settings of a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS). IPsec must be configured to support multiple peers and failover after 120 seconds of idle time on the first entry of the crypto map named Cisco. Drag and drop the commands from the left onto the order on the right.

Answer:

Explanation:

Explanation:
Step 1 = crypto map cisco 1 ipsec-isakmp Step 2 = set peer 192.168.10.1 default Step 3 = set peer
192.168.20.1 Step 4 = set security-association idle-time 120 default
The process of editing the settings of a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS), and configuring IPsec to support multiple peers and failover after 120 seconds of idle time on the first entry of the crypto map named Cisco involves several steps123456.
crypto map cisco 1 ipsec-isakmp: This command is used to create a new entry in the crypto map named
"cisco". The "1" is the sequence number of the entry, and "ipsec-isakmp" specifies that the IPSec security associations (SAs) should be established using the Internet Key Exchange (IKE) protocol13.
set peer 192.168.10.1 default: This command is used to specify the IP address of the default peer for the crypto map entry. In this case, the default peer is at IP address 192.168.10.115.
set peer 192.168.20.1: This command is used to add an additional peer to the crypto map entry. In this case, the additional peer is at IP address 192.168.20.1. This allows the IPsec VPN to support multiple peers56.
set security-association idle-time 120 default: This command is used to set the idle time for the security association. If no traffic is detected over the VPN for the specified idle time (in this case, 120 seconds), the security association is deleted, and the VPN connection fails over to the next peer46.

NEW QUESTION # 26
An engineer must use Cisco vManage to configure an application-aware routing policy Drag and drop the steps from the left onto the order on the right to complete the configuration.

Answer:

Explanation:

Explanation:
Step 1 = Create the groups of interest. Step 2 = Configure the topology. Step 3 = Create the application-aware routing policy. Step 4 = Apply the application-aware routing policy to a specific VPN and sites.
The process of configuring an application-aware routing policy in Cisco vManage involves several steps12.
Create the groups of interest: This is the first step where you define the applications or groups that the policy will affect1.
Configure the topology: This involves setting up the network topology that the policy will operate within1.
Create the application-aware routing policy: After setting up the groups and topology, you then create the application-aware routing policy. This policy tracks network and path characteristics of the data plane tunnels between Cisco SD-WAN devices and uses the collected information to compute optimal paths for data traffic31.
Apply the application-aware routing policy to a specific VPN and sites: Finally, the created policy is applied to a specific VPN and sites. This allows the policy to affect the desired network traffic1.

NEW QUESTION # 27
What is the role of service providers to establish private connectivity between on-premises networks and Google Cloud resources?

  • A. accelerate content delivery through integration with Google Cloud CDN
  • B. provide end-to-end encryption for data transmission using native IPsec
  • C. enable intelligent routing and dynamic path selection using software-defined networking
  • D. facilitate direct, dedicated network connections through Google Cloud Interconnect

Answer: D

Explanation:
The role of service providers to establish private connectivity between on-premises networks and Google Cloud resources is to facilitate direct, dedicated network connections through Google Cloud Interconnect.
Google Cloud Interconnect is a service that allows customers to connect their on-premises networks to Google Cloud through a service provider partner. This provides low latency, high bandwidth, and secure connectivity to Google Cloud services, such as Google Compute Engine, Google Cloud Storage, and Google BigQuery.
Google Cloud Interconnect also supports hybrid cloud scenarios, such as extending on-premises networks to Google Cloud regions, or connecting multiple Google Cloud regions together. Google Cloud Interconnect offers two types of connections: Dedicated Interconnect and Partner Interconnect. Dedicated Interconnect provides physical connections between the customer's network and Google's network at a Google Cloud Interconnect location. Partner Interconnect provides virtual connections between the customer's network and Google's network through a supported service provider partner. Both types of connections use VLAN attachments to establish private connectivity to Google Cloud Virtual Private Cloud (VPC) networks. References:

NEW QUESTION # 28
An engineer needs to configure enhanced policy-based routing (ePBR) for IPv4 by using Cisco vManage.
Drag and drop the steps from the left onto the order on the right to complete the configuration of the ePBR using the CLI add-on template.

Answer:

Explanation:

Explanation:
Enhanced Policy-Based Routing (ePBR) is used to direct packets that arrive at an interface to a specified next-hop. It is very useful in managing a large number of configured access lists more efficiently. In ePBR, the router drops the traffic packets if the next hop configured in the PBR policy is not reachable. To avoid packet loss in such scenarios, you must configure multiple next hops for each access control entry.
Here are the steps to configure ePBR for IPv4 using Cisco vManage:
Configure an extended ACL: This step involves defining the network or the host. For example, you can permit IPv4 traffic from any source to specific hosts.
Configure a class map that matches the ACL: Class maps match the parameters in the ACLs. For instance, you can create a class map of type traffic and match it with the previously created ACL.
Configure the policy map with the action to set the next hop: Policy maps with ePBR then take detailed actions based on the set statements configured. You can configure an ePBR policy map with the class map and set the next hop.
Apply the service policy on the interface: Finally, you apply the ePBR policy map to the interface. For example, you can apply the policy map to a GigabitEthernet interface.

Answer:

Explanation:

Explanation:
Step 1 = Click Configuration, select Templates, and then select Feature Templates. Step 2 = Click Add Template, select the device, and then click Basic Configuration. Step 3 = Shut down the tunnel and then remove the ISAKMP profile. Step 4 = Attach the IKEv2 profile and then run the no shutdown command on the tunnel.
The process of configuring a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router in Controller mode and AWS, and changing the IKE version from IKEv1 to IKEv2 in Cisco vManage involves several steps123.
Click Configuration, select Templates, and then select Feature Templates: This is the first step where you navigate to the Templates section in the Configuration menu of Cisco vManage1.
Click Add Template, select the device, and then click Basic Configuration: In this step, you add a new template for the device and proceed with the basic configuration1.
Shut down the tunnel and then remove the ISAKMP profile: Before changing the IKE version, you need to shut down the existing tunnel and remove the ISAKMP profile that is configured for IKEv12.
Attach the IKEv2 profile and then run the no shutdown command on the tunnel: Finally, you attach the newly created IKEv2 profile to the tunnel and bring the tunnel back up2.

NEW QUESTION # 30

Refer to the exhibits. An engineer needs to configure a site-to-site IPsec VPN connection between an on premises Cisco IOS XE router and Amazon Web Services (AWS). Which two IP prefixes should be used to configure the AWS routing options? (Choose two.)

  • A. 50.50.50.0/30
  • B. 30.30.30.0/30
  • C. 20.20.20.0/24
  • D. 40.40.40.0/24
  • E. 30.30.30.0/24

Answer: B,D

Explanation:
The correct answer is A and E because they are the IP prefixes that match the tunnel interfaces on the Cisco IOS XE router. The AWS routing options should include the local and remote IP prefixes that are used for the IPsec tunnel endpoints. The other options are either the public IP addresses of the routers or the LAN subnets that are not relevant for the IPsec tunnel configuration.

NEW QUESTION # 31

Refer to the exhibit. An engineer successfully brings up the site-to-site VPN tunnel between the remote office and the AWS virtual private gateway, and the site-to-site routing works correctly. However, the end-to-end ping between the office user PC and the AWS EC2 instance is not working. Which two actions diagnose the loss of connectivity? (Choose two.)

  • A. Check the IPsec SA counters.
  • B. On the Cisco VPN router, configure the IPsec SA to allow ping packets.
  • C. Check the security group rules for the host VPC.
  • D. Check the network security group rules on the host VNET.
  • E. On the AWS private virtual gateway, configure the IPsec SA to allow ping packets.

Answer: A,C

Explanation:
The end-to-end ping between the office user PC and the AWS EC2 instance is not working because either the security group rules for the host VPC are blocking the ICMP traffic or the IPsec SA counters are showing errors or drops. To diagnose the loss of connectivity, the engineer should check both the security group rules and the IPsec SA counters. The network security group rules on the host VNET are not relevant because they apply to Azure, not AWS. The IPsec SA configuration on the Cisco VPN router and the AWS private virtual gateway are not likely to be the cause of the problem because the site-to-site VPN tunnel is already up and the site-to-site routing works correctly.

NEW QUESTION # 32
Which method is used to create authorization boundary diagrams (ABDs)?

  • A. show all networks in CIDR notation only
  • B. identify only interconnected systems that are FedRAMP-authorized
  • C. identify all tools as either external or internal to the boundary
  • D. show only minor or small upgrade level software components

Answer: C

Explanation:
According to the FedRAMP Authorization Boundary Guidance document1, the method used to create authorization boundary diagrams (ABDs) is to identify all tools as either external orinternal to the boundary.
The ABD is a visual representation of the components that make up the authorization boundary, which includes all technologies, external and internal services, and leveraged systems and accounts for all federal information, data, and metadata that a Cloud Service Offering (CSO) is responsible for. The ABD should illustrate a CSP's scope of control over the system and show components or services that are leveraged from external services or controlled by the customer1. The other options are incorrect because they do not capture the full scope and details of the authorization boundary as required by FedRAMP. References := FedRAMP Authorization Boundary Guidance document1


NEW QUESTION # 33
Refer to the exhibit.

While troubleshooting an IPsec connection between a Cisco WAN edge router and an Amazon Web Services (AWS) endpoint, a network engineer observes that the security association status is active, but no traffic flows between the devices What is the problem?

  • A. identity mismatch
  • B. IKE version mismatch
  • C. wrong encryption
  • D. wrong ISAKMP policy

Answer: A

Explanation:
An identity mismatch occurs when the local and remote identities configured on the IPsec peers do not match.
This can prevent the establishment of an IPsec tunnel or cause traffic to be dropped by the IPsec policy. In this case, the network engineer should verify that the local and remote identities configured on the Cisco WAN edge router and the AWS endpoint match the values expected by each peer. The identities can be an IP address, a fully qualified domain name (FQDN), or a distinguished name (DN). The identities are exchanged during the IKE phase 1 negotiation and are used to authenticate the peers. If the identities do not match, the peers will reject the IKE proposal and the IPsec tunnel will not be established or will be torn down.

NEW QUESTION # 34
Which architecture model establishes internet-based connectivity between on-premises networks and AWS cloud resources?

  • A. That uses Amazon CloudFrontfor caching and distributing content globally and uses HTTPS for secure data transfer.
  • B. That relies on AWS Elastic Load Balancing (ELB) for traffic distribution and uses SSL/TLS encryption for secure data transmission.
  • C. That employs AWS Direct Connect for a dedicated network connection and uses private IP addresses tor secure communication.
  • D. That establishes an iPsec VPN tunnel with Internet Key Exchange (IKE) for secure key negotiation and encrypted data transmission

Answer: D

Explanation:
The architecture model that establishes internet-based connectivity between on-premises networks and AWS cloud resources is the one that establishes an iPsec VPN tunnel with Internet Key Exchange (IKE) for secure key negotiation and encrypted data transmission. This model is also known as the VPN CloudHub model12. It allows multiple remote sites to connect to the same virtual private gateway in AWS, creating a hub-and-spoke topology1. The VPN CloudHub model provides the following benefits12:
It enables secure communication between remote sites and AWS over the public internet, using encryption and authentication protocols such as IPsec and IKE.
It supports dynamic routing protocols such as BGP, which can automatically adjust the routing tables based on the availability and performance of the VPN tunnels.
It allows for redundancy and load balancing across multiple VPN tunnels, increasing the reliability and throughput of the connectivity.
It simplifies the management and configuration of the VPN connections, as each remote site only needs to establish one VPN tunnel to the virtual private gateway in AWS, rather than multiple tunnels to different VPCs or regions.
The other options are not correct because they do not establish internet-based connectivity between on-premises networks and AWS cloud resources. Option B relies on AWS Elastic Load Balancing (ELB) for traffic distribution and uses SSL/TLS encryption for secure data transmission. However, ELB is a service that distributes incoming traffic across multiple targets within a VPC, not across different networks3. Option C employs AWS Direct Connect for a dedicated network connection and uses private IP addresses for secure communication. However, AWS Direct Connect is a service that establishes a private connection between on-premises networks and AWS, bypassing the public internet4. Option D uses Amazon CloudFront for caching and distributing content globally and uses HTTPS for secure data transfer. However, Amazon CloudFront is a service that delivers static and dynamic web content to end users, not to on-premises networks5.

NEW QUESTION # 35
Which approach does a centralized internet gateway use to provide connectivity to SaaS applications?

  • A. A dedicated, private connection is established between the on-premises infrastructure and the SaaS provider data center using colocation services.
  • B. A cloud-based proxy server routes traffic from the on-premises infrastructure to the SaaS provider data center.
  • C. Internet traffic from the on-premises infrastructure is routed through a centralized gateway that provides access controls for SaaS applications.
  • D. VPN connections are used to provide secure access to SaaS applications from the on-premises infrastructure.

Answer: C

Explanation:
A centralized internet gateway is a network design that routes all internet-bound traffic from the on-premises infrastructure through a single point of egress, typically located at the data center or a regional hub1. This approach allows the enterprise to apply consistent security policies and access controls for SaaS applications, as well as optimize the bandwidth utilization and performance of the WAN links2. A centralized internet gateway can use various technologies to provide connectivity to SaaS applications, such as proxy servers, firewalls, web filters, and WAN optimizers3. However, a cloud-based proxy server (option A) is not a part of the centralized internet gateway, but rather a separate service that can be used to route traffic from the on-premises infrastructure to the SaaS provider data center4. VPN connections (option C) and dedicated, private connections (option D) are also not related to the centralized internet gateway, but rather alternative ways of providing secure and reliable access to SaaS applications from the on-premises infrastructure5. Therefore, the correct answer is option B, which describes the basic function of a centralized internet gateway. References := 1: Designing and Implementing Cloud Connectivity (ENCC) v1.0, Module 1:

NEW QUESTION # 36
A company with multiple branch offices wants a suitable connectivity model to meet these network architecture requirements:
* high availability
* quality of service (QoS)
* multihoming
* specific routing needs
Which connectivity model meets these requirements?

  • A. hub-and-spoke topology using MPLS with static routing and dedicated bandwidth for QoS
  • B. hybrid topology that combines MPLS and SD-WAN
  • C. star topology with internet-based VPN connections and BGP for routing
  • D. fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS

Answer: D

Explanation:
A fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS meets the network architecture requirements of the company. A fully meshed topology provides high availability by eliminating single points of failure and allowing multiple paths between branch offices.
SD-WAN technology enables multihoming by supporting multiple transport options, such as MPLS, internet, LTE, etc. SD-WAN also provides QoS by applying policies to prioritize traffic based on application, user, or network conditions. Dynamic routing allows the SD-WAN solution to adapt to changing network conditions and optimize the path selection for each traffic type. A fully meshed topology with SD-WAN technology can also support specific routing needs, such as segment routing, policy-based routing, or application-aware routing. References:

NEW QUESTION # 37
Refer to the exhibits.

While troubleshooting, a network engineer discovers that the backup path fails between ASBR3 and ASBR4 for traffic between BGP AS6000 and BGP AS6500 when the connection between ASBR1 and ASBR2 goes down. The following configurations were performed on ASBR1:

Which command is missing?

  • A. bgp advertise-best-external
  • B. bgp additional-paths select
  • C. bgp additional-paths Install
  • D. redistribute static

Answer: A

Explanation:
The bgp advertise-best-external command is used to enable the advertisement of the best external path to internal BGP peers. This command is useful when there are multiple exit points from the local AS to other ASes, and the local AS wants to use the closest exit point for each destination. By default, BGP only advertises the best path to its peers, and the best path is usually the one with the lowest IGP metric to the next hop. However, this may not be the optimal path for traffic leaving the local AS, as it may result in suboptimal hot-potato routing or MED oscillations. The bgp advertise-best-external command allows BGP to advertise the best external path, which is the path with the lowest MED among the paths from different neighboring ASes, in addition to the best path. This way, the internal BGP peers can choose the best exit point based on the MED value, rather than the IGP metric. In this scenario, ASBR1 is configured to receive additional paths from ASBR2, which is a route reflector. ASBR2 receivestwo paths for the same prefix from AS6500, one from ASBR3 and one from ASBR4. ASBR2 selects the best path based on the IGP metric to the next hop, and advertises it to ASBR1. However, this path may not be the best external path, as it may have a higher MED value than the other path. If the connection between ASBR1 and ASBR2 goes down, ASBR1 will not have any backup path to reach AS6500, as it does not know the other path from ASBR4. To prevent this situation, ASBR1 should be configured with the bgp advertise-best-external command, so that it can receive the best external path from ASBR2, along with the best path. This way, ASBR1 will have a backup path to reach AS6500, in case the primary path fails. References := IP Routing: BGP Configuration Guide - BGP Additional Paths ... - Cisco, BGP Additional Paths
