NEW QUESTION # 107
Which command must be configured under the MP-BGP configuration mode to enable a 6PE network on a Cisco IOS XR device?
router bgp 64512
Allocate-label all
- A. address-family vpnv6 unicast
- B. address-family vpnv4 unicast
- C. address-family ipv6 unicast
- D. address-family ipv4 unicast
Answer: C
Explanation:
A 6PE deployment uses MP-BGP's IPv6 address family to carry IPv6 routes over an IPv4 MPLS core. On IOS XR, you enable this with the address-family ipv6 unicast stanza under the BGP process alongside allocate-label all.
NEW QUESTION # 108
Refer to the exhibit. PE1 is located at a company's headquarters, with PE2 and PE3 at remote offices. A service provider implemented E-Tree for the company, with PE1 serving at the root and PE2 and PE3 serving as leaf nodes in the topology. For redundancy, PE3 offers some of the same services that that offered at headquarters. However, when the link to PE1 fails, users on PE2 cannot access the services on PE3. Which action must the engineer take to resolve the issue?
- A. Add a secondary IP address to the interface facing the EVPN.
- B. Set the same MAC address for MLACP on each device.
- C. Reconfigure PE3 as a root node.
- D. Change the L2transport encapsulation type to MPLS.
Answer: C
Explanation:
In an EVPN E-Tree, leaf nodes cannot communicate with other leaves-only with roots. With PE1 (root) down, PE2 (leaf) cannot reach services on PE3 (also leaf). Making PE3 a root node permits leaf-to-root forwarding and restores access when the PE1 link fails.
NEW QUESTION # 109
Refer to the exhibit:
A network engineer is implementing an OSPF configuration Based on the output, which statement is true?
- A. OSPFv3 does not run for IPv4 on FastEthemet0/0 until IPv6 routing is enabled on the router and IPv6 is enabled on interface Fastfc.thernet0/0
- B. OSPFv3 cannot be configured for IPv4; OSPFv3 works only for IPv6.
- C. In the ospfv3 1 area 1 ipv4 command, area 0 must be configured instead of area 1.
- D. IPv6 routing not enabled" is just an informational message and OSPFv3 runs for IPv4 on interface FastEthernet0/0 anyway
Answer: A

NEW QUESTION # 113
Refer to the exhibit. While provisioning a new BGP session between the PE and CE router, you issue the as-override command. Which statement describes modification of the prefix before being sent to the CE router (10.10.10.1)?
- A. The first AS changes, but no other autonomous systems change.
- B. The fourth AS changes, but no other autonomous systems change.
- C. The first and fourth autonomous systems change.
- D. The second and third autonomous systems change.
Answer: A
NEW QUESTION # 114
Which condition about MPLS-based IP VPNs must a network architect consider when developing a network solution for customers who run different routing protocols in their LANs?
- A. If the BGP routing protocol is used between the PE and the CE, the asoverride attribute must be configured on the CE router.
- B. If the PE-CE routing protocol is any protocol other than BGP, redistribution of local VPN routes into MP-IBGP is required on the PE router.
- C. If the PE router is configured with BGP and the CE router is configured with RIP, the asoverride attribute must be configured on the PE router.
- D. If the PE-CE routing protocol is BGP, redistribution of local VPN routes into MP-IBGP is required on the CE router.
Answer: B
Explanation:
In an MPLS IP-VPN, routes learned from a CE via OSPF, EIGRP, RIP, or static must be redistributed by the PE into the MP-iBGP address family so they can be carried across the backbone to remote PEs. When PE-CE runs BGP, that BGP session itself carries the VPN routes into MP-iBGP and no additional redistribution is required.
NEW QUESTION # 115
Which two BGP attributes prevent loops in a route reflector environment? (Choose two.)
- A. local preference
- B. origin
- C. originator ID
- D. AS_PATH
- E. cluster ID

NEW QUESTION # 116
To maintain appropriate SLA levels, a network engineer must ensure that the ISP's network devices can perform fault detection, fault isolation, and fault reporting for LAN, MAN, and WAN segments. The implementation must adhere to these requirements:
- supported on all Ethernet interfaces
- allows for proactive fault detection and notification
- provides real-time monitoring and troubleshooting
- scalable and able to support large-scale Ethernet networks
Which action must the network engineer take to meet the requirements-
- A. Enable E-PM to identify and troubleshoot performance issues.

NEW QUESTION # 120
What is a key difference between Layer 2 VPNs and Layer 3 VPNs?
- A. Layer 2 VPNs require the use of a Layer 2 forwarding plane with per-site MAC learning, and Layer 3 VPNs integrate Layer 2 and Layer 3 forwarding with Cisco MPLS TE for traffic differentiation.
- B. Layer 2 VPNs provide Layer 2 transport using pseudowires, and Layer 3 VPNs abstract Layer 2 information using VPLS instances.
- C. Layer 2 VPNs encapsulate Ethernet frames in MPLS packets, and Layer 3 VPNs use labeled BGP routes to distribute IP prefixes across the MPLS core.
- D. Layer 2 VPNs can propagate VLAN tags across the MPLS network, and Layer 3 VPNs use BGP communities to extend MPLS labels across different VRFs.
Answer: C
Explanation:
Layer 2 VPNs transport customer Ethernet frames transparently across the MPLS backbone by encapsulating the Layer 2 frame inside an MPLS pseudowire. Layer 3 VPNs, by contrast, distribute customer IP routes using MP-BGP, attaching MPLS labels to those IP prefixes so the provider core forwards packets based on labeled Layer 3 information rather than Layer 2 frames.
NEW QUESTION # 121

- C. RP/0/RP0/CPU0:PE(config-bgp)#
- D. RP/0/RP0/CPU0:PE(config-bgp-af)#
