What is one characteristic of a spanning tree edge port on an ArubaOS switch?

A. The port link state does not affect the RSTP topology.

B. The port connects to a switch that runs MSTP but in a different region.

C. The port only forwards traffic in VLANs assigned to the instance 0 (IST).

D. The port ignores incoming BPDUs

A network administrator has set up a link between two ArubaOS switches. Both switches have an IP address in VLAN 1 and can ping each other in VLAN 1. The administrator then creates VLAN 2 and tags it on the same link of both switches.

A. How can the administrator verify that the connectivity in VLAN 2 is functional between the two switches7 Use either LLDP or ARP to test connectivity.

B. Use LLDP to test connectivity.

C. Assign each switch an IP address in VLAN 2. and use ICMP to test connectivity.

D. Assign each switch an IP address in VLAN 2. and use LLDP to test connectivity.

What is the purpose of the organization string that is set in the System > Admin settings of an Aruba Instant UI?

A. It configures the SNMP credentials that Aruba AirWave uses to discover the cluster

B. It directs the cluster to the proper Aruba Activate account for Zero Touch Provisioning (ZTP).

C. It prevents unauthorized APs. which do not have the correct organization string, from joining the cluster.

D. It defines the group and folder to which the Instant cluster should be assigned in Aruba AirWave.

Which devices must support Multi-User Multiple Input Multiple Output (MU MIMO) in order for an AP to transmit to multiple clients simultaneously?

A. the transmitting AP and all of the clients that receive simultaneous transmissions

B. all of the APs in a WLAN. but none of the clients

C. the transmitting AP and all of the clients

D. the transmitting AP and at least one of the clients that receives simultaneous transmissions

Two ArubaOS switches connect on a VLAN. and both enable OSPF on that VLAN. Which VLAN OSPF setting must match for the switches to become fully adjacent neighbors?

A. DR priority

B. area ID

C. cost

D. router ID

The switches in the exhibit use RSTP The network administrator needs to add Link 2. Why should the administrator configure Links 1 and 2 as a link aggregation?

A. to combine traffic statistics for the interfaces

B. to prevent a loop from occurring

C. to share traffic more evenly over both links

D. to automatically apply the settings already configured for Link 1 to Link 2

Switch-1 and Switch -2 have the Virtual Switching Framework (VSF) settings shown in the exhibits. The administrator then connects the switches together on the interfaces in the VSF link. The administrator first enables VSF on Switch-1 and confirms the reboot. After Switch-1 reboots, the administrator enables VSF on Switch-2 and confirms the reboot.

What happens?

A. Switch-1 and Switch-2 form a VSF fabric, and Switch-1 becomes the commander.

B. Switch-1 and Switch-2 fail to form a VSF fabric, and al interfaces on both switches remain up.

C. Switch-1 and Switch-2 form a VSF fabric, and all interfaces on Switch-1 are disabled.

D. Switch-1 and Switch-2 form a VSF fabric, and Switch-2 becomes the commander.

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.

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.

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.

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.

A network administrator needs to see the options for the vlan command on an ArubaOS switch. The administrator enters:

Aruba (config)# vlan?

No new output displays.

What should the administrator change to see the vlan command options?

A. Move to the vlan configuration mode before entering vlan? again.

B. Use the Tab key instead of ?.

C. Insert a space in between vlan and ?.

D. Activate help commands globally before entering vlan? again.
