HP HPE2-Z39 Online Questions & Answers

• Question 11:

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

• Question 12:

  What is one reason to configure a dynamic LACP link aggregation instead of a static link aggregation?

  A. so that the link aggregation automatically chooses its operational key
  B. so that the link aggregation can detect the system ID and operational key on the other side of each link
  C. so that the link aggregation can automatically change a passive LACP interface to active mode
  D. so that the link aggregation can include more interfaces with some interfaces on standby
  B. so that the link aggregation can detect the system ID and operational key on the other side of each link

• Question 13:

  

  Which behavior does Switch-1 exhibit on its link aggregations?

  A. It uses LACP to dynamically detect that ports 1 and 3 belong in trk 1. and ports 2 and 4 belong in trk2.
  B. It blocks one or both ports in each link aggregation due to errors detected by LACP.
  C. It sends an SNMP probe to Switch-2 and Swrtch-3 to determine whether it needs to shut down any of these ports.
  D. It load shares traffic on both ports in each LACP link aggregation, which leads to loops and network disruption.
  B. It blocks one or both ports in each link aggregation due to errors detected by LACP.

• Question 14:

  A network administrator needs to reach an ArubaOS switch CLI at a management IP address. The administrator also needs to ensure that the switch entirely rejects Telnet and SSH connections from users in data VLANs. How can the administrator meet these goals?

  A. Configure the management IP address on the default VLAN and set a manager password.
  B. Configure the management IP address on the OOBM port and configure the switch to listen for Telnet and SSH only on this port.
  C. Configure the management IP address on any VLAN except the default VLAN. Set a manager and operator password.
  D. Configure the management IP address on a VTY interface and bind an ACL to this interface.
  A. Configure the management IP address on the default VLAN and set a manager password.

• Question 15:

  

  How can the network administrator find the interface that Switch-3 uses to forward traffic from the Client to the Server?

  A. View the MAC forwarding table.
  B. View the LLDP remote devices list.
  C. View the IP routing table.
  D. View the ARP table.
  C. View the IP routing table.

• Question 16:

  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.
  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.

• Question 17:

  

  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
  A. MSTP

• Question 18:

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

• Question 19:

  Refer to the exhibit.

  

  What does the command output in the exhibit indicate about the status of an Aruba Virtual Switching Framework (VSF) fabric?

  A. The two members of the VSF fabric cannot contact each other, and the other member is the active member.
  B. The two members of the VSF fabric cannot contact each other, and this member is the active member.
  C. The two members of the VSF fabric are currently connected.
  D. The second member of the VSF fabric has not yet joined the fabric, so LLDP-MAD is not operational.
  D. The second member of the VSF fabric has not yet joined the fabric, so LLDP-MAD is not operational.

• Question 20:

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