Question 300

At the Westlake utility network, spoke traffic to the Central grid operations center still traverses the hub even though the design requires direct dynamic spoke-to-spoke forwarding. Which underlying technical condition best accounts for this evidence?

  1. The NHRP tunnel interfaces are not configured to participate in the same logical NHRP network.
  2. The origin spoke has not obtained the peer resolution needed to build an appropriate direct path.
  3. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning.
  4. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.

Explanation

Correct Answer

B:

This diagnosis fits the symptoms at the Westlake utility network. The origin spoke has not obtained the peer resolution needed to build an appropriate direct path. The remedial action is: Verify that NHRP resolves the remote spoke's NBMA address and that direct tunnels are permitted.

Incorrect Answers

A:

This diagnoses a different mechanism: The NHRP tunnel interfaces are not configured to participate in the same logical NHRP network. The reported symptom at the Westlake utility network instead concerns dmvpn spoke-to-spoke nhrp resolution.

C:

The observation at the Westlake utility network does not point to dmvpn phase 3 redirect and shortcut; it points to a different condition. The origin spoke has not obtained the peer resolution needed to build an appropriate direct path.

D:

This diagnoses a different mechanism: Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke. The reported symptom at the Westlake utility network instead concerns dmvpn spoke-to-spoke nhrp resolution.

Question 301

At the Bluewater clinical network, phase 2 DMVPN spokes learn remote LAN routes with the hub as next hop, forcing all spoke traffic through the hub. Which underlying technical condition best accounts for this evidence?

  1. NHRP registration messages are rejected because peers do not agree on their authentication secret.
  2. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.
  3. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning.
  4. The NHRP tunnel interfaces are not configured to participate in the same logical NHRP network.

Explanation

Correct Answer

B:

Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke. That explains the specific symptom at the Bluewater clinical network. A direct corrective action is: Preserve remote spoke tunnel next hops in routing advertisements when using phase 2 direct forwarding.

Incorrect Answers

A:

The observation at the Bluewater clinical network does not point to dmvpn nhrp authentication mismatch; it points to a different condition. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.

C:

That diagnosis belongs to dmvpn phase 3 redirect and shortcut, while the observation at the Bluewater clinical network points to dmvpn phase 2 spoke next-hop preservation.

D:

The observation at the Bluewater clinical network does not point to dmvpn nhrp network id mismatch; it points to a different condition. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.

Question 302

At the Cedarfield retail branch, phase 2 DMVPN spokes learn remote LAN routes with the hub as next hop, forcing all spoke traffic through the hub. Which underlying technical condition best accounts for this evidence?

  1. A fixed GRE destination prevents the tunnel from supporting arbitrary on-demand spoke destinations.
  2. The NHRP tunnel interfaces are not configured to participate in the same logical NHRP network.
  3. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.
  4. The origin spoke has not obtained the peer resolution needed to build an appropriate direct path.

Explanation

Correct Answer

C:

Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke. That explains the specific symptom at the Cedarfield retail branch. A direct corrective action is: Preserve remote spoke tunnel next hops in routing advertisements when using phase 2 direct forwarding.

Incorrect Answers

A:

That diagnosis belongs to dmvpn mgre endpoint capability, while the observation at the Cedarfield retail branch points to dmvpn phase 2 spoke next-hop preservation.

B:

The observation at the Cedarfield retail branch does not point to dmvpn nhrp network id mismatch; it points to a different condition. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.

D:

That diagnosis belongs to dmvpn spoke-to-spoke nhrp resolution, while the observation at the Cedarfield retail branch points to dmvpn phase 2 spoke next-hop preservation.

Question 303

At the Ironwood training campus, a phase 3 DMVPN network has working hub-and-spoke connectivity but repeated branch traffic never discovers a shorter direct path. Which underlying technical condition best accounts for this evidence?

  1. The origin spoke has not obtained the peer resolution needed to build an appropriate direct path.
  2. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning.
  3. The NHRP tunnel interfaces are not configured to participate in the same logical NHRP network.
  4. Dynamic routing multicast is not properly mapped over the nonbroadcast DMVPN transport.

Explanation

Correct Answer

B:

This diagnosis fits the symptoms at the Ironwood training campus. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning. The remedial action is: Verify the hub's NHRP redirect behavior and spokes' shortcut processing for the phase 3 design.

Incorrect Answers

A:

This diagnoses a different mechanism: The origin spoke has not obtained the peer resolution needed to build an appropriate direct path. The reported symptom at the Ironwood training campus instead concerns dmvpn phase 3 redirect and shortcut.

C:

The observation at the Ironwood training campus does not point to dmvpn nhrp network id mismatch; it points to a different condition. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning.

D:

This diagnoses a different mechanism: Dynamic routing multicast is not properly mapped over the nonbroadcast DMVPN transport. The reported symptom at the Ironwood training campus instead concerns dmvpn phase 3 redirect and shortcut.

Question 304

At the Harborview media campus, a phase 3 DMVPN network has working hub-and-spoke connectivity but repeated branch traffic never discovers a shorter direct path. Which underlying technical condition best accounts for this evidence?

  1. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning.
  2. Dynamic routing multicast is not properly mapped over the nonbroadcast DMVPN transport.
  3. Hub-side next-hop rewriting prevents the source spoke from resolving the actual destination spoke.
  4. The NHRP tunnel interfaces are not configured to participate in the same logical NHRP network.

Explanation

Correct Answer

A:

Incorrect Answers

B:

This diagnoses a different mechanism: Dynamic routing multicast is not properly mapped over the nonbroadcast DMVPN transport. The reported symptom at the Harborview media campus instead concerns dmvpn phase 3 redirect and shortcut.

C:

That diagnosis belongs to dmvpn phase 2 spoke next-hop preservation, while the observation at the Harborview media campus points to dmvpn phase 3 redirect and shortcut.

D:

The observation at the Harborview media campus does not point to dmvpn nhrp network id mismatch; it points to a different condition. Required phase 3 NHRP redirect and shortcut exchanges are missing or not functioning.

Question 305

At the Northport logistics site, the DMVPN underlay and NHRP mappings are healthy, but IPsec negotiation fails because peers offer no matching IKE security proposal. Which underlying technical condition best accounts for this evidence?

  1. Underlay IP reachability is present, but the spoke is not registering its tunnel-to-NBMA mapping with the correct NHRP server.
  2. An IP route alone does not guarantee an MPLS label-switched path is available in the core.
  3. The IKE phase cannot agree on a compatible authenticated cryptographic proposal.
  4. The egress VPN label is associated with a specific VRF forwarding action, not a global-table lookup.

Explanation

Correct Answer

C:

The IKE phase cannot agree on a compatible authenticated cryptographic proposal. That explains the specific symptom at the Northport logistics site. A direct corrective action is: Align the mutually supported IKE policy parameters for the approved VPN peers.

Incorrect Answers

A:

That diagnosis belongs to dmvpn spoke registration to hub, while the observation at the Northport logistics site points to ipsec ike proposal disagreement.

B:

The observation at the Northport logistics site does not point to mpls unlabelled core hop; it points to a different condition. The IKE phase cannot agree on a compatible authenticated cryptographic proposal.

D:

That diagnosis belongs to mpls vpn per-vrf forwarding lookup, while the observation at the Northport logistics site points to ipsec ike proposal disagreement.

Question 306

D:

This diagnoses a different mechanism: The destination VRF's route-target import policy does not match the route's export community. The reported symptom at the Hillcrest research lab instead concerns ipsec ike proposal disagreement.

Question 307

At the Granite manufacturing plant, IKE authentication completes but the DMVPN data security association cannot establish after one device changes its IPsec proposal. Which underlying technical condition best accounts for this evidence?

  1. The origin spoke has not obtained the peer resolution needed to build an appropriate direct path.
  2. The penultimate router can remove the outer transport label as an intended MPLS behavior.
  3. An MPLS VPN label stack may serve transport and VPN forwarding purposes at different stages.
  4. IKE identity authentication succeeds, but IPsec data-plane proposals are incompatible.

Explanation

Correct Answer

D:

The evidence at the Granite manufacturing plant supports this condition: IKE identity authentication succeeds, but IPsec data-plane proposals are incompatible. The associated fix is: Align the tunnel protection profile and supported IPsec transform parameters at both peers.

Incorrect Answers

A:

The observation at the Granite manufacturing plant does not point to dmvpn spoke-to-spoke nhrp resolution; it points to a different condition. IKE identity authentication succeeds, but IPsec data-plane proposals are incompatible.

B:

This diagnoses a different mechanism: The penultimate router can remove the outer transport label as an intended MPLS behavior. The reported symptom at the Granite manufacturing plant instead concerns ipsec profile transform mismatch.

Question 309

At the Oakbridge insurance office, short management packets pass through the DMVPN, but larger TCP sessions repeatedly stall after encapsulation. Which underlying technical condition best accounts for this evidence?

  1. The IKE phase cannot agree on a compatible authenticated cryptographic proposal.
  2. An IP route alone does not guarantee an MPLS label-switched path is available in the core.
  3. Encapsulation reduces effective payload MTU, causing large packets to fragment or be dropped.
  4. Underlay IP reachability is present, but the spoke is not registering its tunnel-to-NBMA mapping with the correct NHRP server.

Explanation

Correct Answer

C:

The evidence at the Oakbridge insurance office supports this condition: Encapsulation reduces effective payload MTU, causing large packets to fragment or be dropped. The associated fix is: Set appropriate tunnel MTU and TCP MSS handling based on GRE/IPsec overhead and verified PMTUD behavior.

Incorrect Answers

A:

This diagnoses a different mechanism: The IKE phase cannot agree on a compatible authenticated cryptographic proposal. The reported symptom at the Oakbridge insurance office instead concerns gre over ipsec mtu and mss.
