Question 1

What does link aggregation provide? (Select two.)

Aimproved bandwidth between switches

Bfaster convergence than spanning-tree

Csupport for up to 2 active ports to be bundled together

Ddisables spanning-tree between switches

Eno load balancing

Answer : A, B

Question 2

Which two options are considered Layer 2 protocols? (Select two.)

ASTP

B802.11af

CRIP

D802.1Q

EIPSec

Answer : A, D

Question 3

Which command will save your configuration on an AOS-CX switch so that your changes automatically load on next reboot?

Acopy running-config checkpoint startup-config

Bcopy startup-config running-config

Ccopy running-config default

Dcopy running-config initial-checkpoint

Answer : A

Question 4

Which option correctly describes a two-tier network design?

Adesigned to avoid routing entirely and to have Layer 2 remain across Core, Distribution, and Access layers

Bdivides the Core into two layers (Core and Aggregation) with the Access Layer only handling PoE and Access Control

Cincludes a Distribution Layer to provide Layer 3 features between a routed Core and a Layer 2 Access edge

Ddivides the network into two layers (Access and Core) with the option of routing to the Access Layer

Answer : C

In a two-tier network architecture, the collapsed core layer typically combines the core and distribution layers of a three-tier architecture into a single layer. The main function of the collapsed core layer is to provide high-speed switching and routing of traffic between the distribution layer switches and the access layer switches.

Question 5

Refer to the exhibits.

The AOS-CX 6300M switch is attempting to configure VSF with a peer CX 6300F switch. What is one reason you are receiving the above error when attempting to configure VSF on the AOS-CX 6300M switch?

AAOS-CX VSF links can only be applied to uplink ports with 10G, 25G. and 50G speeds.

BVSF Is not possible between CX 6300M and CX 6300F AOS-CX switches.

CLink 1 cannot be used if the attached CX 6300F VSF member 2 has already assigned link 1

DThe port1/1/21 has been shutdown

Answer : C

Question 6

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.

Question 7

Currently, the prompt on the AOS-CX switch displays:

Core-1(config)# interface 1/1/1

_Core-1 (config-if)#_

What command will immediately return the prompt to privileged mode?

AThe command end

Bpressing ctrl+w

CThe command quit

DThe command exit
