Question 3

What are two features of the three-tier designs? (Choose two.)

Aremoves the distribution layer in favor of a spine-leaf design used in modern data center deployments

Badds a distribution layer to free up resources from the Core for improved performance and routing throughput

Ca more scalable design over by leveraging a distribution layer to handle Layer 3 routing and access control in large deployments

Duses only Layer 2 access on the Access and the Core with Layer 3 routing and access control provided at the distribution layer

Eis considered legacy by requiring a large flat layer-two broadcast domain from Core to Access and should be avoided

Question 7

Refer to the exhibit.

All switches shown are CX 6300M. The links connecting SW3 to both SW1 and SW2 are broken. Multi-Active Detection has not been enabled. What are two results? (Select two.)

AA re-election will occur upon repairing the disabled links between SW2 and SW3. The switch with the highest priority will reclaim the Master role with the lowest bridge mac-address acting the tie-breaker

BThe OSPF adjacency between the OSPF neighbor and the VSF stack switches SW2 and SW3 will remain up. Packets destined for SW3 that are received on SW2 are discarded.

CThe stack will split with SW1 remaining an active VSF Master and SW3 becoming another active VSF Master. Switch 2 will remain a VSF member switch.

DOnly the OSPF adjacency between SW3 and the OSPF neighbor will fail. All routed traffic will be redirected to SW2 instead.

EThe stack will split resulting in SW1 remaining an active VSF Master and SW3 disabling all ports. SW2 will automatically take the VSF Standby role.

Answer : C, E

In a multi-VRF environment, while performing mutual route leaking on the VRRP peers with BGP neighborship established in between and towards the upstream network, the switch installs both routes as ECMP instead of preferring the leaked route.

What happens if a VSF link fails?

If the stack topology is a ring, it will degenerate to a chain when a VSF link in the stack fails.

If the topology is a chain, a VSF link failure will result in a stack being split into two independent stack fragments.

When a stack splits and the master and standby of the stack become part of two different fragments, the standby takes up the master role for its fragment. Network disruption can result because the two fragments are simultaneously active. Aruba highly recommends enabling VSF split-detection to gracefully handle split brain scenarios.

If a stack splits and the master and standby are in the same fragment with the other members on a different fragment, the members-only fragment will:

Reboot.

Come back up.

Wait for communication from the stack master.

What is VSF split-detect?

When a stack splits, the split-detect feature provides a mechanism for the fragments to discover each other.

Once the two stack fragments are discovered, the fragment that has the primary member becomes the active fragment and keeps its front plane (non-VSF) interfaces up and running. The other fragment becomes inactive and all non-VSF interfaces on the inactive fragment are brought down to avoid network disruption.

How do I configure split-detect?

VSF supports split-detection through the management interface.

Connect the management interfaces of the primary and secondary members to the same management VLAN/network or connect them directly to one another. The CLI command to enable split detection is vsf split-detect mgmt.
