  D. Cisco# configure Cisco(config)# segment-routing Cisco(config-sr)# traffic-eng Cisco(config-sr-te)# policy P1 Cisco(config-sr-te-policy)# color 1 end-point
  A. Cisco(config)# segment-routing Cisco(config-sr)# traffic-eng Cisco(config-sr-te)# policy P1 Cisco(config-sr-te-policy)# color 1 end-point ipv4 0.0.0.0

• Question 74:

  Refer to the exhibit.

  

  There is a connectivity issue between Customer-1 and Customer-2. File servers between the customers cannot send critical data. R3 routes are missing from the routing table on the Customer-1 router. All interfaces on Customer-1 are up. Which configuration must be applied to router R2 to correct the problem?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 75:

  Refer to the exhibit

  

  A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0/24. 10.44 5.0/24. 10 44.6.0/24. and 10 44.7.0/24 subnets

  The new router has been configured for OSPF area 2. and it is advertising the four connected networks.

  The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders

  Which action resolves the issue?

  A. On router 3, configure an access list to filter the networks.
  B. On router 2, configure a route map to filter the networks.
  C. Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.
  D. Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.
  D. Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.

• Question 76:

  Refer to the exhibit.

  

  All routers in the network are in area 12, with IS-IS running in the default configuration as the IGP. To avoid congestion on the link from R1 to R2, the network architect planned for traffic from R1 to R3 to pass through R4. To meet this requirement, a network engineer set the metric from R1 to R4 to a cost of 15, but the traffic is still traveling through R2. Which action must the engineer take to resolve the issue?

  A. Change the default metric to 20 on all links and disable wide-area metrics.
  B. Change the cost on the link from R1 to R2 to 11 and enable narrow metrics.
  C. Change the cost on the link from R1 to R4 to 5.
  D. Change the IS-IS administrative distance to 10.
  C. Change the cost on the link from R1 to R4 to 5.

• Question 77:

  Refer to the exhibit. How are packets directed through the data plane when SRv6 is implemented?

  

  A. An ordered list of segments is encoded in a routing extension header
  B. The MPLS data plane is used to push labels onto IGP routes
  C. A stack of labels represents an ordered list of segments
  D. The packet is encapsulated with a header and trailer encoding the ordered list of segments
  A. An ordered list of segments is encoded in a routing extension header

• Question 78:

  Refer to the exhibit.

  

  Excessive routes are flooding from network 150.0.0.0 into AS100. Internet traffic between AS400 and AS300 is working normally. No route controlling mechanism is applied on incoming and outgoing traffic. Which configuration resolves the issue?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 79:

  Refer to the exhibit.

  

  An engineering team implemented IS-IS on the network, with several different areas. Recently, router R6 in area 3 has been experiencing excessive CPU usage. To reduce the load, a network engineer implemented route summarization on R2. However, R6 is still receiving the full routes from all routers. Which action must the engineer take to resolve the excessive CPU usage?

  A. Configure all routers as Level 1/2 routers so that route summarization functions throughout the network.
  B. Configure routers R3 and R5 to send summary routes to R6.
  C. Configure the Level 2 router R6 to manage summarization for the network.
  D. Configure router R1 to send only the default route to R2 and R4.
  B. Configure routers R3 and R5 to send summary routes to R6.

• Question 80:

  An engineer with an employee ID: 4535:15:507 must implement PIM-SSM in the network to support a new multicast messaging service. All the routers in the network run a distance vector routing protocol. Unicast routing is established on the network and is working normally. What must the engineer enable to continue the implementation process?

  A. IGMPv3 on all interfaces that participate in multicast
  B. PIM RP feature on the network
  C. PIM dense mode on all devices on the network
  D. PIM dense mode and IGMPv2 on all interfaces that participate in multicast
