Implementing Cisco Enterprise Network Core Technologies (ENCOR) 350-401 Practice Test 28

Question 270

During acceptance testing after evaluate the full spanning-tree priority vector rather than local cost alone., which evidence is most relevant?

  1. Port roles transition to forwarding promptly during a tested link failure.
  2. Both interfaces report trunking and tagged VLAN traffic passes.
  3. Both ports remain operational trunks and carry the approved tagged VLANs.
  4. `show spanning-tree detail` shows the superior BPDU and chosen port role.

Explanation

Correct Answer

D:

`show spanning-tree detail` shows the superior BPDU and chosen port role. This is the targeted operational evidence for the change. STP compares root ID then path cost sender bridge ID and port IDs. Merely entering the configuration or seeing a management session is less conclusive than observing the resulting behavior.

Incorrect Answers

A:

This observation validates another operation: Use RSTP or MST with correct edge and point-to-point link roles. Rapid STP converges through proposal/agreement without old 802.1D timers on suitable links. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

B:

This observation validates another operation: Set compatible trunk operational modes and verify DTP negotiation policy. An access/trunk mismatch prevents the expected VLAN tagging behavior. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

C:

This observation validates another operation: Force static trunk mode with consistent native and allowed VLAN settings on both ends. An explicitly configured 802.1Q trunk operates independently of dynamic trunk negotiation. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

Question 271

A Layer-2 ring needs fast recovery and alternate path behavior. What is the most appropriate corrective measure?

  1. Add VLAN 30 to the allowed VLAN list on both sides.
  2. Correct the native VLAN to match on both trunk endpoints.
  3. Use RSTP or MST with correct edge and point-to-point link roles.
  4. Confirm VLAN 50 is active locally and permitted by the trunk.

Explanation

Correct Answer

C:

Rapid STP converges through proposal/agreement without old 802.1D timers on suitable links. The most direct remediation is use RSTP or MST with correct edge and point-to-point link roles. A practical acceptance test is port roles transition to forwarding promptly during a tested link failure. This distinguishes a configured intention from operational success.

Incorrect Answers

A:

This choice addresses a different situation: An 802.1Q trunk carries VLAN 10 but not VLAN 30 after a maintenance change. An allowed-VLAN restriction stops the specified traffic on an otherwise operational trunk. It does not specifically correct the issue here: a Layer-2 ring needs fast recovery and alternate path behavior.

B:

This choice addresses a different situation: Two switches carry untagged traffic into different native VLANs. Mismatched native VLANs put untagged frames into unintended broadcast domains. It does not specifically correct the issue here: a Layer-2 ring needs fast recovery and alternate path behavior.

D:

This choice addresses a different situation: VLAN 50 exists in the database but never appears in the forwarding section of a trunk. Allowed VLAN and active VLAN are separate checks for trunk forwarding. It does not specifically correct the issue here: a Layer-2 ring needs fast recovery and alternate path behavior.

Question 272

An operator has applied the following change: use RSTP or MST with correct edge and point-to-point link roles. Which observation best confirms it works?

  1. `show interfaces trunk` lists VLAN 30 as allowed and active.
  2. Port roles transition to forwarding promptly during a tested link failure.
  3. CDP warnings clear and both trunk ports show the same native VLAN.
  4. `show interfaces trunk` lists VLAN 50 as both allowed and forwarding.

Explanation

Correct Answer

B:

Port roles transition to forwarding promptly during a tested link failure. This is the targeted operational evidence for the change. Rapid STP converges through proposal/agreement without old 802.1D timers on suitable links. Merely entering the configuration or seeing a management session is less conclusive than observing the resulting behavior.

Incorrect Answers

A:

This observation validates another operation: Add VLAN 30 to the allowed VLAN list on both sides. An allowed-VLAN restriction stops the specified traffic on an otherwise operational trunk. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

C:

This observation validates another operation: Correct the native VLAN to match on both trunk endpoints. Mismatched native VLANs put untagged frames into unintended broadcast domains. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

D:

This observation validates another operation: Confirm VLAN 50 is active locally and permitted by the trunk. Allowed VLAN and active VLAN are separate checks for trunk forwarding. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

Question 273

An OSPF adjacency stays in EXSTART with mismatched interface MTUs. Which action most directly addresses this situation?

  1. Make the OSPF neighbors' MTU settings consistent.
  2. Recognize normal DROTHER-to-DROTHER 2-WAY state on a broadcast segment.
  3. Set the OSPF interface network type to point-to-point where appropriate.
  4. Match hello/dead interval configuration on peers.

Explanation

Correct Answer

A:

OSPF database description exchange can fail when neighbors disagree on MTU. The most direct remediation is make the OSPF neighbors' MTU settings consistent. A practical acceptance test is `show ip ospf neighbor` progresses beyond EXSTART to FULL. This distinguishes a configured intention from operational success.

Incorrect Answers

B:

This choice addresses a different situation: Two OSPF routers on an Ethernet VLAN stay in 2-WAY despite healthy hellos. DROTHER routers need full adjacency with DR/BDR but not with each other. It does not specifically correct the issue here: an OSPF adjacency stays in EXSTART with mismatched interface MTUs.

C:

This choice addresses a different situation: An OSPF point-to-point link suffers needless DR-election behavior. Point-to-point OSPF forms a direct adjacency without DR or BDR election. It does not specifically correct the issue here: an OSPF adjacency stays in EXSTART with mismatched interface MTUs.

D:

This choice addresses a different situation: An OSPF adjacency flaps due to different hello and dead timers. OSPF neighbors require compatible hello/dead values. It does not specifically correct the issue here: an OSPF adjacency stays in EXSTART with mismatched interface MTUs.

Question 274

An operator has applied the following change: make the OSPF neighbors' MTU settings consistent. Which observation best confirms it works?

  1. `show ip ospf neighbor` shows FULL adjacency to DR/BDR and 2-WAY among DROTHERs.
  2. Both routers reach FULL and show point-to-point network type.
  3. Both interfaces report matching timers and stable FULL adjacency.
  4. `show ip ospf neighbor` progresses beyond EXSTART to FULL.

Explanation

Correct Answer

D:

`show ip ospf neighbor` progresses beyond EXSTART to FULL. This is the targeted operational evidence for the change. OSPF database description exchange can fail when neighbors disagree on MTU. Merely entering the configuration or seeing a management session is less conclusive than observing the resulting behavior.

Incorrect Answers

A:

This observation validates another operation: Recognize normal DROTHER-to-DROTHER 2-WAY state on a broadcast segment. DROTHER routers need full adjacency with DR/BDR but not with each other. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

B:

This observation validates another operation: Set the OSPF interface network type to point-to-point where appropriate. Point-to-point OSPF forms a direct adjacency without DR or BDR election. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

C:

This observation validates another operation: Match hello/dead interval configuration on peers. OSPF neighbors require compatible hello/dead values. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

Question 275

Two OSPF routers on an Ethernet VLAN stay in 2-WAY despite healthy hellos. What is the most effective configuration or design response?

  1. Align addressing and subnet membership on the connected interfaces.
  2. Investigate one-way hello reachability and hello neighbor lists.
  3. Recognize normal DROTHER-to-DROTHER 2-WAY state on a broadcast segment.
  4. Assign a unique router ID and restart the process as required.

Explanation

Correct Answer

C:

DROTHER routers need full adjacency with DR/BDR but not with each other. The most direct remediation is recognize normal DROTHER-to-DROTHER 2-WAY state on a broadcast segment. A practical acceptance test is `show ip ospf neighbor` shows FULL adjacency to DR/BDR and 2-WAY among DROTHERs. This distinguishes a configured intention from operational success.

Incorrect Answers

A:

This choice addresses a different situation: An OSPF neighbor never appears because interface network masks differ. Neighbors need compatible directly connected interface reachability. It does not specifically correct the issue here: two OSPF routers on an Ethernet VLAN stay in 2-WAY despite healthy hellos.

B:

This choice addresses a different situation: Two routers exchange OSPF hellos but the neighbor remains INIT. INIT means a router sees hellos without seeing its own RID acknowledged. It does not specifically correct the issue here: two OSPF routers on an Ethernet VLAN stay in 2-WAY despite healthy hellos.

D:

This choice addresses a different situation: An OSPF router ID conflicts with a neighbor on the same domain. OSPF relies on unique router identifiers for its LSDB and adjacency. It does not specifically correct the issue here: two OSPF routers on an Ethernet VLAN stay in 2-WAY despite healthy hellos.

Question 276

After implementing recognize normal DROTHER-to-DROTHER 2-WAY state on a broadcast segment., which operational evidence should an engineer collect?

  1. Interface addresses share the intended subnet and hello exchange begins.
  2. `show ip ospf neighbor` shows FULL adjacency to DR/BDR and 2-WAY among DROTHERs.
  3. Neighbor debug shows bidirectional hello recognition after correction.
  4. `show ip ospf` reports unique RIDs and neighbor becomes stable.

Explanation

Correct Answer

B:

`show ip ospf neighbor` shows FULL adjacency to DR/BDR and 2-WAY among DROTHERs. This is the targeted operational evidence for the change. DROTHER routers need full adjacency with DR/BDR but not with each other. Merely entering the configuration or seeing a management session is less conclusive than observing the resulting behavior.

Incorrect Answers

A:

This observation validates another operation: Align addressing and subnet membership on the connected interfaces. Neighbors need compatible directly connected interface reachability. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

C:

This observation validates another operation: Investigate one-way hello reachability and hello neighbor lists. INIT means a router sees hellos without seeing its own RID acknowledged. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

D:

This observation validates another operation: Assign a unique router ID and restart the process as required. OSPF relies on unique router identifiers for its LSDB and adjacency. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

Question 277

An OSPF neighbor never appears because interface network masks differ. Which change should the network engineer prioritize?

  1. Align addressing and subnet membership on the connected interfaces.
  2. Set the OSPF interface network type to point-to-point where appropriate.
  3. Match hello/dead interval configuration on peers.
  4. Match OSPF authentication method and key identifiers across neighbors.

Explanation

Correct Answer

A:

Neighbors need compatible directly connected interface reachability. The most direct remediation is align addressing and subnet membership on the connected interfaces. A practical acceptance test is interface addresses share the intended subnet and hello exchange begins. This distinguishes a configured intention from operational success.

Incorrect Answers

B:

This choice addresses a different situation: An OSPF point-to-point link suffers needless DR-election behavior. Point-to-point OSPF forms a direct adjacency without DR or BDR election. It does not specifically correct the issue here: an OSPF neighbor never appears because interface network masks differ.

C:

This choice addresses a different situation: An OSPF adjacency flaps due to different hello and dead timers. OSPF neighbors require compatible hello/dead values. It does not specifically correct the issue here: an OSPF neighbor never appears because interface network masks differ.

D:

This choice addresses a different situation: An OSPF link is configured for MD5 authentication only on one side. Authentication mismatch causes hello packets to be rejected. It does not specifically correct the issue here: an OSPF neighbor never appears because interface network masks differ.

Question 278

The change request says: align addressing and subnet membership on the connected interfaces. Which verification result is most decisive?

  1. Both routers reach FULL and show point-to-point network type.
  2. Both interfaces report matching timers and stable FULL adjacency.
  3. Neighbor reaches FULL and OSPF authentication failure counters stop.
  4. Interface addresses share the intended subnet and hello exchange begins.

Explanation

Correct Answer

D:

Interface addresses share the intended subnet and hello exchange begins. This is the targeted operational evidence for the change. Neighbors need compatible directly connected interface reachability. Merely entering the configuration or seeing a management session is less conclusive than observing the resulting behavior.

Incorrect Answers

A:

This observation validates another operation: Set the OSPF interface network type to point-to-point where appropriate. Point-to-point OSPF forms a direct adjacency without DR or BDR election. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

B:

This observation validates another operation: Match hello/dead interval configuration on peers. OSPF neighbors require compatible hello/dead values. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

C:

This observation validates another operation: Match OSPF authentication method and key identifiers across neighbors. Authentication mismatch causes hello packets to be rejected. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

Question 279

An OSPF point-to-point link suffers needless DR-election behavior. Which remediation best resolves the described symptom?

  1. Investigate one-way hello reachability and hello neighbor lists.
  2. Assign a unique router ID and restart the process as required.
  3. Set the OSPF interface network type to point-to-point where appropriate.
  4. Use conditional `default-information originate` behavior matching route presence.

Explanation

Correct Answer

C:

Point-to-point OSPF forms a direct adjacency without DR or BDR election. The most direct remediation is set the OSPF interface network type to point-to-point where appropriate. A practical acceptance test is both routers reach FULL and show point-to-point network type. This distinguishes a configured intention from operational success.

Incorrect Answers

A:

This choice addresses a different situation: Two routers exchange OSPF hellos but the neighbor remains INIT. INIT means a router sees hellos without seeing its own RID acknowledged. It does not specifically correct the issue here: an OSPF point-to-point link suffers needless DR-election behavior.

B:

This choice addresses a different situation: An OSPF router ID conflicts with a neighbor on the same domain. OSPF relies on unique router identifiers for its LSDB and adjacency. It does not specifically correct the issue here: an OSPF point-to-point link suffers needless DR-election behavior.

D:

This choice addresses a different situation: A default route must be originated from the ASBR only while an external route exists. OSPF default origination without `always` depends on a usable default route. It does not specifically correct the issue here: an OSPF point-to-point link suffers needless DR-election behavior.

Question 280

A post-change test follows this action: set the OSPF interface network type to point-to-point where appropriate. Which result demonstrates success?

  1. Neighbor debug shows bidirectional hello recognition after correction.
  2. Both routers reach FULL and show point-to-point network type.
  3. `show ip ospf` reports unique RIDs and neighbor becomes stable.
  4. An O*E2 default appears only while the ASBR has the required default.

Explanation

Correct Answer

B:

Both routers reach FULL and show point-to-point network type. This is the targeted operational evidence for the change. Point-to-point OSPF forms a direct adjacency without DR or BDR election. Merely entering the configuration or seeing a management session is less conclusive than observing the resulting behavior.

Incorrect Answers

A:

This observation validates another operation: Investigate one-way hello reachability and hello neighbor lists. INIT means a router sees hellos without seeing its own RID acknowledged. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

C:

This observation validates another operation: Assign a unique router ID and restart the process as required. OSPF relies on unique router identifiers for its LSDB and adjacency. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.

D:

This observation validates another operation: Use conditional `default-information originate` behavior matching route presence. OSPF default origination without `always` depends on a usable default route. It is not decisive evidence that the change under examination works as required. A relevant verification must exercise its particular control or forwarding outcome.
