Question 200

A risk review for the following wired-network case asks what should be avoided: Two access layers see periodic Layer 2 loops after a redundant cable is installed. Which assumption creates the GREATEST implementation risk?

Combining members with mismatched peer aggregation identities
Disabling STP to make every link forward simultaneously
Treating a VSF stack as two independent VSX control planes
Assuming a VLAN created locally automatically appears on every uplink

Explanation

Correct Answer

Disabling STP to make every link forward simultaneously. That shortcut fails because spanning-tree control is required when redundant bridged links can form loops. Instead, the appropriate approach is to configure a consistent MSTP region and root strategy for the bridged topology.

Incorrect Answers

This misconception choice fits a different situation: A link aggregation group contains two ports but only one member forwards traffic. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to disabling STP to make every link forward simultaneously.

This misconception choice fits a different situation: A department wants multiple 6300 access switches to behave as one manageable stack. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to disabling STP to make every link forward simultaneously.

This misconception choice fits a different situation: Two switches must exchange VLAN 20 and VLAN 30 but a user in VLAN 30 cannot cross the uplink. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to disabling STP to make every link forward simultaneously.

Question 201

Before changing switch configuration, an engineer investigates: Two access layers see periodic Layer 2 loops after a redundant cable is installed. Which FIRST check is most useful for isolating the cause?

Inspect VSF member states, stack links and role election
Inspect LACP actor and partner data, member status and port settings
Inspect peer state, VSX synchronization and LACP status on both sides
Inspect MST region name, revision, VLAN mappings and root path

Explanation

Correct Answer

Inspect MST region name, revision, VLAN mappings and root path. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that spanning-tree control is required when redundant bridged links can form loops.

Question 202

An implementation change is planned for: Two access layers see periodic Layer 2 loops after a redundant cable is installed. Which preventive control BEST reduces unnecessary outage and security risk?

Stage a failover test with independent peer paths
Define root priorities and test topology changes before production
Use documented matched speed and trunk policy for the bundle
Plan standby member placement and isolated stacking paths

Explanation

Correct Answer

Define root priorities and test topology changes before production. This safeguard is appropriate before the change to configure a consistent MSTP region and root strategy for the bridged topology; it reduces exposure to the mistake of disabling STP to make every link forward simultaneously.

Incorrect Answers

Question 203

A first repair attempt for this situation failed: Two access layers see periodic Layer 2 loops after a redundant cable is installed. The review found the mistaken approach of disabling STP to make every link forward simultaneously. Which targeted recovery action BEST restores the intended design?

Correct MST region inconsistency and restore a loop-free topology
Remove the incompatible member, align both peers and rejoin it
Add only required VLAN 30 membership and verify both ends
Repair the stack adjacency and restore the approved member order

Explanation

Correct Answer

Correct MST region inconsistency and restore a loop-free topology. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the network has a stable root and blocks redundant Layer 2 paths as intended.

Question 204

An HPE Aruba Networking engineer faces this wired-network scenario: A link aggregation group contains two ports but only one member forwards traffic. Which implementation action BEST addresses the requirement?

Configure a consistent MSTP region and root strategy for the bridged topology
Align LACP configuration, port compatibility and the peer's aggregation settings
Configure the trunk's allowed VLANs and native VLAN deliberately on both ends
Deploy a supported VSF topology with defined conductor, standby and member links

Explanation

Correct Answer

LACP negotiation and member consistency determine usable bundle capacity. The targeted implementation is to align LACP configuration, port compatibility and the peer's aggregation settings. The deployment succeeds when both eligible member links join one operational aggregate without instability.

Question 205

After implementing the approved change — Align LACP configuration, port compatibility and the peer's aggregation settings — for this scenario: A link aggregation group contains two ports but only one member forwards traffic. Which observed result BEST verifies the outcome?

The downstream device keeps connectivity through the surviving peer
A tagged VLAN 30 test passes across the inter-switch uplink
The network has a stable root and blocks redundant Layer 2 paths as intended
Both eligible member links join one operational aggregate without instability

Explanation

Correct Answer

Both eligible member links join one operational aggregate without instability. This is the observable acceptance evidence for the decision to align LACP configuration, port compatibility and the peer's aggregation settings. It demonstrates the principle that lACP negotiation and member consistency determine usable bundle capacity.

Incorrect Answers

Question 206

An HPE Aruba Networking design review examines: A link aggregation group contains two ports but only one member forwards traffic. Which technical principle BEST explains the required approach?

A trunk forwards only VLANs permitted by its effective membership
LACP negotiation and member consistency determine usable bundle capacity
VSX multi-chassis LAG operation depends on peer and downstream consistency
VSF joins compatible physical members into a managed switch stack

Explanation

Correct Answer

LACP negotiation and member consistency determine usable bundle capacity. The case therefore calls for this specifically controlled action: align LACP configuration, port compatibility and the peer's aggregation settings. The acceptance evidence is that both eligible member links join one operational aggregate without instability.
