Q47. Refer to the exhibit.

Click the Exhibit button.
Referring to the exhibit, you must provide VRF Internet access over a single connection for VPN-A Site 1, which connects to PE-1.
Which two statements are correct in this scenario? (Choose two.)

You must use the RIB group to move a default route, which is learned through BGP, from the inet. o table to the VPN-A. inet. 0 table.

You do not need to use the RIB group to move interface routes from the inet. o table to the VPN-A. inet. 0 table.

You do not need to use the RIB group default route, which is learned through BGP, from the inet. o table to the VPN-A. inet. 0 table.

You must use the RIB group to move interface routes from the inet . 0 table to the VPN-A. inet. 0 table.

In the provided exhibit, the configuration involves using a RIB (Routing Information Base) group to facilitate internet access for VPN-A Site 1 through PE-1. The goal is to provide VRF Internet access over a single connection.
1. **Understanding RIB Groups**:
– RIB groups allow for the import and export of routes between different routing tables.
– In this scenario, we have two RIBs: `inet.0` (the main routing table) and `VPN-A.inet.0` (the VRF-specific routing table).
2. **Statement Analysis**:
– **A. You must use the RIB group to move a default route, which is learned through BGP, from the inet.0 table to the VPN-A.inet.0 table.**
– Correct. To provide Internet access to VPN-A, the default route (0.0.0.0/0) learned via BGP in the `inet.0` table must be made available in the `VPN-A.inet.0` table. This is done using the RIB group to import the default route.
– **B. You do not need to use the RIB group to move interface routes from the inet.0 table to the VPN-A.inet.0 table.**
– Correct. Interface routes (connected routes) are typically directly added to both the global and the VRF routing tables without needing a RIB group. These routes are known to the VRF because the interfaces are part of the VRF configuration.
– **C. You do not need to use the RIB group default route, which is learned through BGP, from the inet.0 table to the VPN-A.inet.0 table.**
– Incorrect. As discussed, the default route needs to be imported into the VRF’s routing table using a RIB group to enable Internet access for the VRF.
– **D. You must use the RIB group to move interface routes from the inet.0 table to the VPN-A.inet.0 table.**
– Incorrect. Interface routes are directly associated with the VRF interfaces and are automatically known to the VRF routing table. There is no need to use a RIB group for these routes.
**Conclusion**:
The correct answers are:
**A. You must use the RIB group to move a default route, which is learned through BGP, from the inet.0 table to the VPN-A.inet.0 table.**
**B. You do not need to use the RIB group to move interface routes from the inet.0 table to the VPN-A.inet.0 table.**

Q48. You are a network architect for a service provider and want to offer Layer 2 services to your customers You want to use EVPN for Layer 2 services in your existing MPLS network.
Which two statements are correct in this scenario? (Choose two.)

Segment routing must be configured on all PE routers.

VXLAN must be configured on all PE routers.

EVPN uses Type 2 routes to advertise MAC address and IP address pairs learned using ARP snooping

EVPN uses Type 3 routes to join a multicast tree to flood traffic.

Q49. Which two statements are correct about VPLS tunnels? (Choose two.)

LDP-signaled VPLS tunnels only support control bit 0.

LDP-signaled VPLS tunnels use auto-discovery to provision sites

BGP-signaled VPLS tunnels can use either RSVP or LDP between the PE routers.

BGP-signaled VPLS tunnels require manual provisioning of sites.

Q50. Referring to the exhibit, which two statements are true? (Choose two.)

The multihop configuration is used for load balancing.

This route is learned from the same AS number.

This route is learned from two different AS numbers.

The multipath configuration is used for load balancing.

Q51. In IS-IS, which two statements are correct about the designated intermediate system (DIS) on a multi-access network segment? (Choose two)

A router with a priority of 10 wins the DIS election over a router with a priority of 1.

A router with a priority of 1 wins the DIS election over a router with a priority of 10.

On the multi-access network, each router forms an adjacency to every other router on the segment

On the multi-access network, each router only forms an adjacency to the DIS.
