NEW QUESTION # 176

Refer to the exhibit. R101 is peering with R102 and R103, and R201 is peering with R202 and R203 using iBGP Labeled Unicast address families. The OSPF area 0 border routers are in a full iBGP Labeled Unicast mesh, and VPNv4 routes are exchanged directly between PE routers R101 and R201 through iBGP. Which address family-level configuration must be applied on ABR R102 on ABR R102 to support a Unified MPLS routing architecture with partitioned IGP domains?

NEW QUESTION # 177

Refer to the exhibit. Router 1 and Router 2 were installed in the data center. Router 1 is the core router in the network, but it fails to establish an OSPF peering with Router 2. and customer traffic is unable to pass. Router
1 also reports an increase in CPU and memory usage. However, the CPU for R2 is stable. Which action resolves this issue?

• A. Disable Cisco Express Forwarding on Router 2.
• B. Enable MPLS on Router 2.
• C. Change the MTU to 1524 on Router 1.
• D. Change the transport mode to WAN on Router 1.

Answer: C

Explanation:
The issue of Router 1 failing to establish an OSPF peering with Router 2, and the increase in CPU and memory usage can be attributed to a mismatch in MTU (Maximum Transmission Unit) sizes. In OSPF, for a successful adjacency to be formed, the MTU size on the interfaces that are trying to form this adjacency must match. In this case, changing the MTU to 1524 on Router 1 will make it compatible with Router 2, allowing OSPF peering to be established and customer traffic to pass through successfully.

NEW QUESTION # 181
Refer to the exhibit.

CE1 and CE2 require connectivity to the internet through the ISP connected to PE3 What should an engineer configure to complete this task?

• A. CE1 and CE2 must be configured to use a static default route with a next-hop of PE3 to reach internet routes.
• B. PE1 must be configured with an import route target in the CE1 VRF that matches the export route target for the internet VRF on PE3.
• C. CE1 and CE2 must be configured with a route distinguisher in the PE1 VRF that dynamically imports the route from the internet.
• D. PE2 must be configured to serve as a route reflector for PE3 routes learned from the internet. PE2 then shares the routes with CE1 and CE2.

Answer: A

Explanation:
In this scenario, CE1 and CE2 need connectivity to the internet through the ISP connected to PE3. The most straightforward approach is to configure CE1 and CE2 with a static default route pointing to PE3 as the next- hop for internet-bound traffic. This ensures that any traffic destined for the internet will be routed directly to PE3, which is directly connected to the internet. Other options (A, B, and D) involve more complex configurations and are not necessary for this specific task.

NEW QUESTION # 187
How does TI-LFA reduce packet loss in segment routing?

• A. It calculates loop-free backup paths that are rapidly implemented in case of a link failure.
• B. It determines which link to use when load balancing to prevent packet fragmentation loss.
• C. It establishes multiple labels per path using more than one IGP.
• D. It enables path selection in SR-TE to support MPLS label allocation.

Answer: A

Explanation:
TI-LFA (Topology Independent Loop-Free Alternate) reduces packet loss in segment routing by precomputing loop-free backup paths for each possible link or node failure. These backup paths are calculated using the network topology and are immediately implemented upon detection of a failure. This ensures near-instantaneous traffic rerouting without requiring full reconvergence of the IGP, significantly minimizing packet loss during failures.

NEW QUESTION # 188
Refer to the exhibit:

Which statement about the status of the neighbor relationship between R1 and R2 is true?

• A. The neighbor relationship is down because R2 is operating as a Level 1 router and the two routers are in different area
• B. The neighbor relationship is down because the two routers are configured with different area types
• C. The neighbor relationship is down because the two routers are in the same subnet.
• D. The neighbor relationship is up because R2 is level 1 and level 2 router.

Answer: C

NEW QUESTION # 189

NEW QUESTION # 190
Refer to the exhibit.

An engineer is configuring two routers to support MPLS LDP sessions between them. The R1 configuration is complete, and work has started on R2 as shown. Which additional configuration must the engineer apply to R2 to complete the task?

• A. Option B
• B. Option D
• C. Option A
• D. Option C

Answer: D

Explanation:
To establish MPLS LDP sessions between two routers, both routers must be configured to support MPLS on the interfaces that connect them. The configuration shown for R2 includes enabling MPLS label protocol LDP and configuring interfaces Ethernet1/0 and Ethernet1/1. However, to complete the MPLS LDP session setup, R2 also needs to have MPLS enabled on the interface toward R1. This is done by entering the interface configuration mode for the relevant interface and using the mpls ip command. This command enables MPLS forwarding for IP packets on the interface, which is necessary for LDP to advertise and map labels to the IP routes.

NEW QUESTION # 191
A router RP is configured to perform MPLS LDP graceful restart.
Which three steps are included when the RP sends an LDP initialization message to a neighbor to establish an LDP session? (Choose three.)

• B. Type-9 LSA
• C. Learn from Network (L) flag, set to 1
• D. Recovery Time field
• E. Learn from Neighbor (N) flag, set to 1
• F. Graceful restart capability in OPEN message

NEW QUESTION # 194
Refer to the exhibit.

An engineer is configuring an administrative domain in the given multi-vendor environment with PIM-SM.
Which feature must the engineer implement so that devices will dynamically learn the RP?

• A. Auto-RP
• B. SSM
• C. BIDIR-PIM
• D. BSR

Answer: D

Explanation:
In a multi-vendor environment with PIM-SM, the Bootstrap Router (BSR) mechanism is used for devices to dynamically learn the Rendezvous Point (RP). BSR is a protocol feature that automates the dissemination of RP information in a PIM domain. This feature allows routers to automatically discover the RP set in use, which simplifies configuration and management compared to static RP configurations or Auto- RP.

NEW QUESTION # 197
Which service is a VNF role?

• A. Storage
• B. Compute
• C. Network
• D. Firewall

Answer: D

Explanation:
A Virtual Network Function (VNF) role refers to a network function that is executed in software and can be deployed on a Network Functions Virtualization Infrastructure (NFVI). A firewall serves as a VNF role because it performs network functions, such as filtering traffic and security management, in software form rather than as a physical device.
