Updated On: 23-Jul-2026

Refer to the exhibit. An engineer configures the router 10.1.100.10 for EIGRP autosummarization so that R1 should receive the summary route of 10.0.0.0/8. However, R1 receives more specific /24 routes.



Which action resolves this issue?

  1. Router R1 should configure ip summary address eigrp (AS number) 10.0.0.0 255.0.0.0 for the R1 Fast Ethernet 0/0 connected interface.
  2. Router R1 should configure ip route 10.0.0.0 255.0.0.0 null 0 for the routes that are received on R1.
  3. Router 10.1.100.10 should configure ip route 10.0.0.0 255.0.0.0 null 0 for the routes that are summarized toward R1.
  4. Router 10.1.100.10 should configure ip summary address eigrp (AS number) 10.0.0.0 255.0.0.0 for the R1 Fast Ethernet 0/0 connected interface.

Answer(s): D





Refer to the exhibit. Which command must be configured to make VRF CCNP work?

  1. interface Loopback0
    ip address 10.1.1.1 255.255.255.0
    vrf forwarding CCNP
  2. interface Loopback0
    ip address 10.1.1.1 255.255.255.0
  3. interface Loopback0
    vrf forwarding CCNP
  4. interface Loopback0
    ip address 10.1.1.1 255.255.255.0
    ip vrf forwarding CCNP

Answer(s): B

Refer to the exhibits. An engineer investigates a routing issue on R1 and finds that traffic destined to 5.5.5.0/24 does not take all of the paths.

Which action resolves the issue?

Refer to the exhibits. An engineer investigates a routing issue on R1 and finds that traffic destined to 5.5.5.0/24 does not take all of the paths.

Which action resolves the issue?

  1. Increase the variance value in EIGRP.
  2. Decrease the variance value in EIGRP.
  3. Remove the adjacency of R3 from EIGRP.
  4. Stop advertising 192.168.13.0/24 in EIGRP.

Answer(s): A

DRAG DROP (Drag and Drop is not supported)
Drag and drop the MPLS VPN concepts from the left onto the correct descriptions on the right.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Refer to the exhibits. Phase-3 tunnels cannot be established between spoke-to-spoke in DMVPN. Which two commands are missing? (Choose two.)

  1. The ipnhrp redirect command is missing on the spoke routers.
  2. The ipnhrp shortcut command is missing on the spoke routers.
  3. The ipnhrp redirect command is missing on the hub router.
  4. The ipnhrp shortcut command is missing on the hub router.
  5. The ipnhrp map command is missing on the hub router.

Answer(s): B,C



Which protocol is used to determine the NBMA address on the other end of a tunnel when mGRE is used?

  1. NHRP
  2. IPsec
  3. MP-BGP
  4. OSPF

Answer(s): A



A DMVPN single hub topology is using IPsec + mGRE with OSPF.
What should be configured on the hub to ensure it will be the designated router?

  1. route map to set the metrics of learned routes to 110
  2. tunnel interface of the hub with ipnhrpospfdr
  3. OSPF priority to 0
  4. OSPF priority greater than 1

Answer(s): D



What are two purposes of using IPv4 and VPNv4 address-family configurations in a Layer 3 MPLS VPN? (Choose two.)

  1. RD is prepended to the IPv4 route to make it unique.
  2. The VPNv4 address consists of a 64-bit route distinguisher that is prepended to the IPv4 prefix.
  3. MP-BGP is used to allow overlapping IPv4 addresses between customers to advertise through the network.
  4. The IPv4 address is needed to tag the MPLS label.
  5. The VPNv4 address is used to advertise the MPLS VPN label.

Answer(s): A,E
