• Question 11:

  

  A broadcast packet arrives tagged for VLAN 2 on the Member 2 link of Trk2. What does Member 2 do?

  A. It forwards the packet on its local link in Trk1.

  B. It forwards the packet over the VSF link to Member 1, and then Member 1 forwards the packet on its link in Trk1.

  C. It uses LACP to communicate with the commander on the VSF link, and then follows the commander directions.

  D. It uses a hash to select one of the links in Trk1, and then forwards the packet locally or on the VSF link, based on the decision.

  Correct Answer: B

• Question 12:

  A network administrator wants to apply a critical PoE priority to any ArubaOS switch port that connects to an Aruba AR The priority should be applied dynamicaly based on LLDP messages received from the AP. Which step should the administrator take to meet this goal?

  A. Configure the PoE usage setting on all ports as class and make sure that Aruba APs are defined as Class 4 devices.

  B. Configure the PoE usage setting on all ports as tfdp.

  C. Enable LLDP MED TLV extensions on the switch port.

  D. Enable the default AP profile bound to the Aruba AP device type.

  Correct Answer: D

• Question 13:

  

  

  A network administrator has set up OSPF to enable communications between subnets 10.1.4.0/24 and 10.1.8.0/24. Swffch-4 is not receiving a route to 10.1.4.0/24.

  What should the network administrator do to help fix this issue?

  A. Fix the router IDs on al switches so that they are valid.

  B. Enable OSPF on VLAN 4 on Switch-1.

  C. Configure Switch-1 with a better DR priority on VLANs 100 and 101.

  D. Verify that Switch-2 and Switch-3 are part of the backbone area.

  Correct Answer: B

• Question 14:

  A network administrator needs to configure Virtual Switching Framework (VSF) for the first time on an ArubaOS switch. The administrator enters this command:

  

  The administrator then wants to provision member 2 settings. What must the administrator do before provisioning these settings?

  A. Specify the model type for member 1.

  B. Configure SNMP settings that match settings configured on member 2

  C. Join member 2 to the VSF fabric.

  D. Enable VSF on the switch and reboot.

  Correct Answer: B

• Question 15:

  An Aruba Virtual Switching Framework (VSF) fabric has 10GbE interfaces assigned to its VSF link. The

  network administrator wants to change the link to use 40GbE interfaces.

  Which procedure follows the best practices and requirements to set up the VSF links?

  A. Create an LACP link aggregation on the 40GbE interfaces, and then add them to the VSF link.

  B. Shut down the standby member, remove the VSF link, and then re-create the link with only 40GbE interfaces.

  C. Create a second VSF link that uses the 40GbE interfaces, and then remove the first VSF link.

  D. Add the 40GbE interfaces to the VSF link, and then remove the 10GbE interfaces from the link.

  Correct Answer: A

• Question 16:

  What is one requirement to combine Aruba 5400R zl2 Series switches in a Virtual Switching Framework (VSF) fabric?

  A. One of the switches must be an Aruba 5412R switch, white the other member can be any switch in the 5400R series.

  B. Both of the members must have two management modules.

  C. The switches must operate in v3-modute only mode: any modules of an earlier version are automatically disabled.

  D. The interfaces assigned to the VSF link must be pre-configured as part of a link aggregation.

  Correct Answer: A

• Question 17:

  

  Based on this ArubaOS switch output, what can a network administrator determine about the spanning tree topology?

  A. Port 2 is an edge port

  B. Port 3 will become the root port if the current root port becomes unavailable.

  C. Switch-C is the root bridge of the topology.

  D. Trk1 offers the lowest cost path to the common spanning tree root.

  Correct Answer: C

• Question 18:

  A company has a cluster of Aruba Instant APs (lAPs). The company wants to add a new IAP to the cluster. What should network administrators ensure before they connect the new IAP?

  A. that the new IAP has been provisioned with an IP address and the IP address of the cluster virtual controller (VC)

  B. that the switch port for the AP is untagged for the same VLAN as the current cluster

  C. that Aruba Activate is configured with provisioning rules for the IAP

  D. that the DHCP server has the correct options 60 and 43

  Correct Answer: A

• Question 19:

  

  This ArubaOS switch receives traffic without a VLAN tag on a switch port 1. The traffic is destined to a MAC address learned on port 2. What does the switch do with the traffic?

  A. It forwards the traffic on port 2 without a VLAN tag.

  B. It floods the traffic on port 2 on all VLANs.

  C. It drops the traffic.

  D. It forwards the traffic on port 2 with a VLAN tag of 5.

  Correct Answer: C

• Question 20:

  An ArubaOS switch has an LACP link aggregation with two links. How does the switch balance traffic over the links?

  A. It assigns the first conversation (as defined by the load-balancing algorithm) to the first link, the second conversation to the second link, and so on, in a round-robin fashion.

  B. It assigns the first packet to the first link, the second packet to the second link, and so on, in a round-robin fashion.

  C. It assigns all traffic to the first link until the link reaches a bandwidth threshold; it then assigns traffic to the second link.

  D. It assigns each conversation (as defined by the load-balancing algorithm) to a consistent link, based on a hash.

  Correct Answer: B
