Question # 51

Refer to the exhibit.

Routers within the cluster are not receiving the desired prefixes. What must be done to fix the issue?

A.

Clients in that cluster must have full mesh connectivity between eBGP peers.

B.

No client-to-client must be disabled.

C.

Clients in that cluster must have full mesh connectivity between iBGP peers.

D.

No client-to-client reflection must be enabled.

Question # 52

Which command is used to enable BIDIR-PIM under global configuration mode for Cisco IOS XE Sofware?

A.

ip pim bidir-enable

B.

ipv4 pim bidir-enable

C.

ip multicast-routing

D.

ip pim bidir

Question # 53

What is a requirement of PIM-SM?

A.

It requires Cisco Express Forwarding to be enabled.

B.

It must be enabled on loopback interfaces only

C.

It requires OSPF to be configured on the network.

D.

It must use an RP

Question # 54

Refer to the exhibit. A network engineer just replaced five routers on this OSPF network. When the routing protocol is brought up, R5 cannot reach routes that originate on R1. The engineer verified that all connected links have established neighbor relationships. R5 reaches routes originating on R3 and R4. Which a ction resolves the issue?

A.

Configure an OSPF virtual link to bridge Area 0 on routers R3 and R4.

B.

Configure automatic neighbor discovery on RI and R5.

C.

Configure OSPF to have a contiguous Area O.

D.

Configure each link to be point-to-point.

Question # 55

What is the role of a segment routing mapping server?

A.

It advertises a local SID mapping policy to all of the mapping clients

B.

It works with IGP instances to calculate the prefix-SIDs in the absence of a mapping policy

C.

It selects multiple mapping entries to create overlapping active mapping policies

D.

It reads and translates remotely received SIDs from other mapping servers to create SID mapping entries

Question # 56

Refer to the exhibit.

A service provider technician is working on a multicast issue for a customer. While

checking the multicast table, the technician notices that no flags are present for the (1.1.1.1, 239.1.1.1) entry, yet flags are present for the (1.1.1.1, 232.1.1.1) entry.

Which factor might explain this issue?

A.

Only the administratively scoped range is permitted

B.

Only ASM is permitted

C.

Only the default SSM range is permitted

D.

Only GLOP is permitted

Question # 57

Refer to the exhibit

An engineer is configuring service traffic from router R1 to R6 as shown. Which additional configuration must the engineer implement so that the LDP and SR domains will participate and interwork with each other?

A.

Router2(config)# segment-routing

Router2(config-sr)# ldp mapping-server

Router2(config-sr-ms)# prefix-sid-map

Router2(config-sr-ms-map)#

B.

Router2(config)# segment-routing

Router2(config-sr)# sr mapping-server

Router2(config-sr-ms)# ldp-sid-map

Router2(config-sr-ms-map)# address-family ipv4

Router2(config-sr-ms-map-af)# 10.1.1.1/32 500 r ange 50

C.

Router2(config)# segment-routing

Router2(config-sr)# mapping-server

Router2(config-sr-ms)# prefix-sid-map

Router2(config-sr-ms-map)# address-family ipv4

Router2(config-sr-ms-map-af)# 10.1.1.1/32 500 range 50

D.

Router2(config)# segment-routing

R outer2(config-sr)# ldp mapping-server

Router2(config-sr-ms)# prefix-sid-map

Router2(config-sr-ms-map)# address-family ipv4

Router2(config-sr-ms-map-af)# 2.2.2.2/32 500 range 40

Question # 58

Refer to the exhibit.

BGP is running on the network, and CE1 currently prefers routes to the internet via PE 1 A network engineer must manipulate the BGP routes that CE1 receives from PE2 to be more desirable The engineer configured a route map using MED and applied it on CE1 outbound from PE2. However, after a BGP soft reset. PE1 is still preferred. Which action must the engineer take so that PE2 is chosen as the next hop?

A.

Update the route map to use only weight to manipulate the path.

B.

Configure the route map with MED and local preference to manipulate the route outbound

C.

Apply the route map on CE1 In the inbound direction.

D.

Configure the route map with AS path prepend to manipulate the AS path to exit the autonomous system

Question # 59

Drag and drop the features from the left into the order of operations for SRv6 SSH field creation and forwarding on the right.

Question # 60

An engineer is troubleshooting slow performance issues on a customer’s network after the last multicast configuration change was applied on it While checking the running configuration on the router the engineer notices there are many ip igmp join-group commands applied on several interfaces of the router which caused the high CPU utilization usage. What action must the engineer take to solve this issue?

A.

Configure ip igmp static-group command on all interfaces

B.

Remove ip igmp join-group command on all unnecessary interfaces

C.
