Question 1

Core# configure terminal

Core(config)# vrf Green

Core(config-vrf)# exit

Core(config)#

Core(config)# interface vlan 50

Core(config-if-vlan)# ?

Given the configuration on the CORE switch shown above, what command would follow to assign the switched virtual interface (SVI) vlan 50 to the VRF created?

ACore(config-if-vlan)# vrf attach Green

BCore(config-if-vlan)# ip vpn-instance Green

CCore(config-if-vlan)# ip vrf forwarding Green

DCore(config-if-vlan)# routing-context Green vrf

Answer : A

Question 2

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 3

Refer to the exhibit.

Switch-1 is not the root bridge. The ports shown are all the connected pointtopoint interfaces. What Role (hidden by the blue rectangle) will be assigned to the Lag 1 interface?

AAlternate

BBackup

CRoot

DDesignated

Answer : C

Question 4

Refer to the exhibit.

What configuration is needed in order for "show LLDP configuration" to show this output?

Anone; LLDP is enabled by default on Aruba switches

Bconfiguring LLDP both globally and on the interfaces

Cenabling LLDP on the interfaces only

Dconfiguring LLDP globally only

Answer : A

Question 5

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 6

What connectivity commands are available on AOS-CX switches? (Choose two.)

Anetstatus

Btraceroute

Cping

Dpathping

Etracert

Answer : B, C

Question 7

Which statement is correct regarding powering an Aruba Access Point?

APoE or PoE+ is only used with Ethernet that is carried over multi-mode fiber cabling.

BUsing switchports for this reason is unnecessary, because Aruba Access Points typically use an AC to DC
power adapter to draw power.

CPoE or PoE+ enabled switchports are rarely used given concerns about causing electrical interference, with the data also carried over Ethernet cabling.

DMost administrators use PoE or PoE+ enabled switchports to provide both Ethernet connectivity and power to the AP.
