300-515 Exam Question 56

How do VPNv6 routes propagate between PEs?

A.The CE uses NAT64 to translate the IPv6 address into a unique IPv4 address, which is sent between sites.

B.The CE uses Unified MPLS to assign labels to IPV6 traffic only, and then it sends traffic to the PEs using those labels.

C.A DHCP server assigns an IPv4 address and an IPv6 address to each host, and the CE sends traffic from those hosts between sites.

D.The PE assigns an RD to each VRF and prepends the value to shared IPV6 routes, which allows two or more sites to use a single IP address space.

300-515 Exam Question 57

In which configuration mode is a route distinguisher configured in a Cisco IOS XR router?

A.config-bgp

B.config-vrf

C.config-vrf-af

D.config-bgp-af

E.config-bgp-vrf

300-515 Exam Question 58

Refer to the exhibit. A service provider implemented E-Tree for a customer, with PE1 serving as the root and PE2 and PE3 as leaf nodes in the topology. Each PE router is deployed in a different physical location. PE2 and PE3 cannot communicate with one another. Which action must the network engineer take to resolve the issue?

A.Configure dot1q encapsulation on the L2transport interface.

B.Configure the ICCP group in singleton mode.

C.Configure either PE2 or PE3 to be a root node.

D.Configure different MAC addresses for MLACP.

300-515 Exam Question 59

How do Ethernet virtual circuits provide a way for service providers to maximize the use of VLAN tags?

A.They add an additional tag to VLANs that allows up to two switch ports to use the same globally configured VLAN ID.

B.They separate the classification and forwarding concepts for VLAN tagging which allows multiple switch ports to use the same VLAN ID without it being configured globally.

C.They redefine the VLAN tag to include classification, forwarding, and QoS using MPLS labels and EXP bits

D.They assign VLAN IDs to VTP domains so that the same VLAN ID are used more than once globally.

300-515 Exam Question 60

Refer to the exhibit. An organization is running H-VPLS on a network comprising four routers in a hub-and-spoke topology with R1 as the hub.
An engineer added a new spoke with multiple VCs to the network, and now traffic cannot flow properly.
How should the engineer update the configuration on R1 to correct the problem?

A.Disable Cisco Discovery Protocol to allow for neighbor discovery

B.Disable spanning tree to allow loops to occur within the hub-and-spoke topology.

C.Disable Cisco Discovery Protocol to allow MPLS to share labels between the designated spokes

D.Disable split horizon to allow multiple VCs per spoke
