HPE2-Z39 Online Practice Questions and Answers

A network administrator suspects that interfaces in a link aggregation have been accidentally connected to multiple switches. The administrator wants to find the hostnames of the switches on the other side of the interfaces. How can the administrator find this information?

A. Use the show lace command to view LACP information.

B. Use the show trunks command to view link aggregation information.

C. Use the show interface command to view detailed interface status.

D. Use the show lldp info remote-device command to view LLDP information.

A switch receives a broadcast frame in VLAN 2 on link aggregation, trk 1. How does the switch handle the broadcast?

A. It floods it out all interfaces that are assigned to VLAN 2. including all links in Mel.

B. It floods it out all interfaces that are assigned to VLAN 2. including one designated link in trk1.

C. It floods it out all interfaces that are assigned to VLAN 2 except any interfaces assigned to trk 1.

D. It floods it out all interfaces that are assigned to VLAN 2. including all links in trk1 except the link on which the broadcast arrived.

The switches shown in the exhibit are ArubaOS switches that implement RSTP. The switches are configured with the spanning tree priorities shown in the exhibit, and they use their default costs on ports. Based on the topology, which port is a root port?

A. Switch A port 1

B. Switch B port 2

C. Switch C port 1

D. Switch C port 2

A port on an ArubaOS switch currently has its default VLAN assignment. The network administrator wants the port to continue to be part of the default VLAN. The administrator also wants the port to support VLANs 2 and 3.

What should the administrator do to accomplish this?

A. Add VLAN 2 to the port as an untagged VLAN assignment and VLAN 3 as a tagged assignment.

B. Add VLANs 2 and 3 to the VLAN permit list for the port.

C. Add VLANs 2 and 3 to the port as tagged VLAN assignments.

D. Add the port to hybrid VLAN 2 and 3.

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.

What is the effect if a network administrator sets a spanning tree priority on an ArubaOS switch interface?

A. The interface priority helps to determine which switch on the link is elected root.

B. The interface priority determines whether this switch or the connected switch has the Designated port on the link.

C. The interface priority breaks a tie when multiple interfaces offer the same lowest cost path to the root through the same neighbor

D. The interface priority prevents a rogue switch connected to the interface from becoming root.

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 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.

This exhibit shows the topology for a company campus LAN. Each access layer switch will be the default router for the devices connected to it. The company needs to permit the following:

1.

Communications between devices in an subnets

2.

Support for efficient traffic paths during normal operation and in situations in which a link fails

3.

Fast failover if a link fails

Which feature should the network administrator configure on the ArubaOS switches to support these requirements?

A. MSTP

B. RIP

C. Static Routes

D. OSPF
