Question 6 of 74

Click the Exhibit button.

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

The devices advertising this route into EVPN are 10.0.2.12 and 10.0.2.22.

This route is learned through EBGP.

The device advertising this route into EVPN is 192.168.101.5.

This is an EVPN Type-2 route.

Correct Answer: C, D

The device advertising this route into EVPN is 192.168.101.5, as indicated by the Nexthop and Originator ID fields. Additionally, this is an EVPN Type-2 route, as highlighted by the type listed in the route extensive output.

Question 7 of 74

Click the Exhibit button.

You are running a service provider network and must transport a customer's IPv6 traffic across your IPv4-based MPLS network using BGP. You have already configured mpls ipv6-tunneling on your PE routers.

Which two statements are correct about the BGP configuration in this scenario? (Choose two.)

You must configure family inet6 labeled-unicast between PE routers.

You must configure family inet6 add-path between PE and CE routers.

You must configure family inet6 unicast between PE and CE routers.

You must configure family inet6 unicast between PE routers.

Correct Answer: A, C

To transport IPv6 traffic across an IPv4-based MPLS network using BGP, you need to configure family inet6 labeled-unicast between PE routers to exchange IPv6 routes with MPLS labels. Additionally, you must configure family inet6 unicast between PE and CE routers to exchange IPv6 routes without labels. The setup ensures that IPv6 traffic can be properly transported over the MPLS network by leveraging tunneling techniques. Therefore, configuring these address families accurately enables seamless integration between different network segments.

Question 8 of 74

When using 0SPFv3 for an IPv4 environment, which statement is correct?

OSPFv3 only supports IPv4.

OSPFv3 is not backward compatible with IPv4.

OSPFv3 supports both IPv6 and IPv4, but not in the same routing instance.

OSPFv3 supports IPv4 only on interfaces with family inet6 defined.

Correct Answer: D

OSPFv3 supports both IPv4 and IPv6, but it requires IPv6 to be configured on the interfaces. This means that for OSPFv3 to be used in an IPv4 environment, the interfaces need to have the IPv6 address family (inet6) defined. Without this, OSPFv3 will not function correctly for IPv4.

Question 9 of 74

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.

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.

VXLAN must be configured on all PE routers.

Correct Answer: B, C

EVPN (Ethernet VPN) is a technology that allows for Layer 2 services over an MPLS network by utilizing extensions to BGP. EVPN uses different types of BGP routes to distribute information about the Layer 2 network. Type 2 routes are used to advertise the MAC address and IP address pairs that are learned via ARP snooping or other mechanisms. Type 3 routes are used for creating multicast distribution trees that allow for the flooding of broadcast, unknown unicast, and multicast traffic within the EVPN instance. Segment routing and VXLAN are not mandatory for EVPN deployment in an MPLS network.

Question 10 of 74

You are configuring a Layer 3 VPN between two sites. You are configuring the vrf-target target: 65100:100 statement in your routing instance.

In this scenario, which two statements describe the vrf-target configuration? (Choose two.)

This value is used to identify BGP routes learned from the remote PE device.

This value is used to add a target community to BGP routes advertised to the local CE device.

This value is used to add a target community to BGP routes advertised to the remote PE device.

This value is used to identify BGP routes learned from the local CE device.

Correct Answer: A, C

The vrf-target configuration in a Layer 3 VPN is used to manage the import and export of VPN routes. Specifically, the vrf-target target statement assigns a target community to routes. This helps in identifying BGP routes learned from remote PE devices (option A) and adds a target community to BGP routes advertised to remote PE devices (option C). This way, it ensures that routes are properly shared and understood between different parts of the VPN.
