HP HP Certifications HPE2-Z39 Questions & Answers

• Question 21:

  

  The Virtual Switching Framework (VSF) fabric and other switches connect on LACP link aggregations. They use OSPF for routing. What should a network administrator do to help network connectivity continue uninterrupted if the commander fails?

  A. Enable OSPF graceful restart (non-stop OSPF) on the VSF fabric.

  B. Configure LLDP-MAD.on the VSF fabric.

  C. Configure a unique OSPF router ID on the standby member OOBM port.

  D. Install a standby management module in the standby member.

  Correct Answer: B

• Question 22:

  A network administrator connects several new Aruba Instant APs (at factor/ defaults) to a switch. After waiting several minutes for the cluster to form, the administrator is ready to provision the cluster. The VLAN on the ports connected to the APs has no DHCP services.

  How can the administrator contact the Instant Ul and provision the APs with static IP addresses?

  A. Access the cluster using Aruba Activate.

  B. Connect to the Instant SSID and open a Web browser.

  C. Access https://vc.arubanetworks.com from a device connected in the AP VLAN.

  D. Access the default IP address. 192.168.1.1. from a device connected in the AP VLAN.

  Correct Answer: A

• Question 23:

  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.

  Correct Answer: C

• Question 24:

  Currently the routing switches shown in the exhibit have only connected IP routes. The network administrator needs to add static routes to support communications between subnet 10.1.4.0/24 and subnet 10.1.8.0/24. Which switch or switches require a static route to 10.1.8.0/24?

  A. Switch-3 only

  B. Switch-1 and Switch-3

  C. Switch-1 only

  D. Switch-1 and Switch-2

  Correct Answer: B

• Question 25:

  A network has ArubaOS switches and an Aruba Instant cluster with IP addresses on 10.1.255.0/24 The network administrator wants to manage the devices in Aruba AirWave. The administrator uses the SNMP credentials configured on the switches to create a scan set for 10.1.255.0/24. The scan discovers the switches but not the Instant cluster.

  What should the administrator do to discover the cluster in AirWave?

  A. Re-configure the scan set to use the Aruba Instant default SNMPv3 user admin

  B. Configure SNMP credentials in the Instant Ul.

  C. Specify the AirWave IP address in the Instant Ul System > Admin settings.

  D. Install the Instant cluster self-signed certificate on AirWave.

  Correct Answer: B

• Question 26:

  

  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.

  Correct Answer: C

• Question 27:

  

  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

  Correct Answer: C

• Question 28:

  On an ArubaOS switch, what is the difference between an SNMPv2c community with manager unrestricted rights and an SNMPv2 community with operator unrestricted rights?

  A. The manager unrestricted community has read-write access to all managed objects on the switch; the operator unrestricted community has read-write access to some objects but not to any Config objects.

  B. The manager unrestricted community uses the Telnet/SSH password assigned to the manager to authenticate SNMP servers: the operator unrestricted community uses the Telnet/SSH password assigned to the operator.

  C. The manager unrestricted community has read-write access to the switch, but the operator unrestricted community has read-only access.

  D. The manager unrestricted community uses encryption, but the operator unrestricted community uses plaintext communication

  Correct Answer: A

• Question 29:

  

  The exhibit shows settings for a WLAN on an Aruba Instant cluster. To which VLAN is wireless user traffic assigned?

  A. to the VLAN defined for wireless users in Aruba AirWave

  B. to the default VLAN on switches connected to the Instant APs

  C. to the default VLAN defined in the System settings in the Instant Ul

  D. to the untagged VLAN on switch ports connected to the Instant APs

  Correct Answer: D

• Question 30:

  Network administrators need to access an ArubaOS switch CLI remotely. How can the administrator ensure that all data passed between management stations and the switch is encrypted?

  A. Create local user accounts and enable command authorization.

  B. Configure operator and manager passwords for Telnet access.

  C. Create an SSH key. enable SSH. and disable Telnet.

  D. Enable HTTPS access.

  Correct Answer: D
