Question # 116

A network administrator is planning a new network with a segment-routing architecture using a distributed control plane. How is routing information distributed on such a network?

A.

Each segment is signalled by an SR controller, but each segment makes Its own steering decisions based on SR policy.

B.

Each segment is signalled by MPLS, and each segment makes steering decisions based on the routing policy pushed by BGP.

C.

Each segment is signalled by an SR controller that makes the steering decisions for each node.

D.

Each segment is signalled by a compatible routing protocol and each segment makes its own steering decisions based on SR policy.

Question # 117

Refer to the exhibit. ISP_A is a Tier-1 ISP that provides private Layer 2 and Layer 3 VPN services across the globe using an MPLS-enabled backbone network. Routers R1, R2, R13, and R14 are PE devices. ASRs R3 and R4 and ASBRs R11 and R12 are acting as route reflectors with preconfigured next-hop-self for all BGP neighbors. After the network experienced IGP RIB overflow with multiple routes, a network engineer is working on a more scalable network design to minimize the impact on local RIBs. The solution should be based on RFC 3107 and maintain existing QoS capabilities.

Which task must the engineer perform to achieve the goal?

A.

Implement Seamless Segment Routing on the ABR routers.

B.

Implement MPLS Traffic Engineering on PE routes only.

C.

Implement Hierarchical MPLS VPLS across all LDP-enabled routers.

D.

Implement Unified MPLS on all MPLS-enabled routers.

Question # 118

Refer to the exhibit. A company recently deployed a new network using OSPF in the core to share routes. The network administrator selected OSPF as the routing protocol because of its ability to maintain a route database. When the new network was started up, all routers booted normally, but the link between routers R1 and R2 failed to come up. The two routers are located in the same rack at the data center. Which task should an engineer perform to correct the problem?

A.

Synchronize the dead timers.

B.

Change one of the OSPF router IDs so that the router IDs are in different subnets

C.

Change the OSPF process ID on one of the devices so that the two IDs match

D.

Configure the MTUs on the interface to match.

Question # 119

Refer to the exhibit. A Tier-2 ISP provides MPLS Layer 3 VPNs to customers throughout the region. BGP and OSPF are used as routing protocols in the backbone, and all routers are running Cisco IOS-XE software. Customer A has requested a private connection between two of its offices. The company has plans to interconnect more offices across the country soon, so the solution should allow for the addition of new sites without reconfiguring the existing sites. The customer is using an IPv6 addressing scheme. R1 has been preconfigured with vrf definition Customer_A and assigned rd 1441:3421.

Which two tasks should the engineer perform on R1 to configure the private connection? (Choose two.)

A.

Configure address-family unicast ipv6 Customer_A under the BGP configuration.

B.

Configure export route-target 1441:3421 under the VRF configuration.

C.

Configure address-family ipv6 unicast under the VRF configuration.

D.

Configure route-target both 1441:3421 under the address family configuration.

E.

Configure address-family unicast ipv6 vrf Customer_A under the OSPF configuration.

B.

Option B

C.

Option C

D.

Option D
