HP HP Certifications HPE6-A45 Questions & Answers

• Question 51:

  A company needs to update the software on a VSF fabric with two Aruba 540GR switches.

  What can the network administrator do to minimize downtime during the update?

  A. Ensure that both switches have redundant management modules

  B. Deploy the new software with the enhanced PAPI feature

  C. Upload the new software through the OOBM ports

  D. Implement a sequenced reboot of the new software

  Correct Answer: D

• Question 52:

  What is a reason for hello packets between two OSPF routers?

  A. to permit an OSPF adjacency between two VSF fabrics

  B. to monitor connectivity with the neighbor, but not exchange the routing table

  C. to establish an area that is not directly connected to the backbone Area 0

  D. to permit OSPF to operate between two routers that also run VRRP

  Correct Answer: B

• Question 53:

  What must an OSPF router do when it receives a link state update?

  A. It must participate in a new election for the Designated Router and Backup DR.

  B. It must initiate a graceful restart timer.

  C. It must re-establish adjacency with its Designated Router and Backup DR.

  D. It must run the shortest path first algorithm.

  Correct Answer: D

• Question 54:

  Refer to the exhibit.

  

  A company has IP phones that are LLDP-MED capable. The exhibit shows the configuration for the VLAN to which IP phones belong, as well as the configuration for ports to which phones will connect. AOS-Switches at the access layer are set up to use LLDP-MED. The administrator wants to automatically provision the phones to send traffic with the right VLAN tag and priority.

  Which additional configuration step must the administrator complete?

  A. Specify LLDP-MED as the global LLDP mode

  B. Specify the voice setting in VLAN 3

  C. Enable LMA and configure the proper LMA profiles

  D. Enable 802.1X and MAC-based VLANs on the ports

  Correct Answer: B

• Question 55:

  Refer to the exhibit.

  

  A known unicast packet is received from Switch-1 on the standby and must be forwarded to Switch-2. How does the VSF fabric decide which port in the aggregated link should forward the packet?

  A. The standby uses its own port in the link aggregation to forward the fabric.

  B. The standby sends the packet to the commander over a VSF link, and the commander decides the correct port.

  C. The standby uses the typical load sharing algorithm, and it might select either its port or the commander's port.

  D. The standby selects the port on the designated forwarder for the aggregation.

  Correct Answer: A

• Question 56:

  Refer to the exhibit.

  

  Switch-1 and Switch-2 connect on interface A23. The switches experience a connectivity issue. The network administrator sees that both switches show this interface as up. The administrator sees the output shows in the exhibit on Switch-1.

  What is a typical issue that could cause this output?

  A. a hardware issue, such as a broken cable

  B. asymmetric routing introduced by a routing configuration error

  C. an issue with queuing, caused by mismatched QoS settings

  D. mismatched IP addresses on the VLAN for the link

  Correct Answer: A

• Question 57:

  A company wants to implement role-based tunneled node on AOS-Switches.

  Which solution should be included in the plan to help apply the roles?

  A. a RADIUS server, such as Aruba ClearPass

  B. an SNMP server, such as Aruba AirWave

  C. Aruba Mobility Manager (MM)

  D. Aruba Meridian

  Correct Answer: A

• Question 58:

  A customer wants access layer switches that support routing, ACLs, backplane stacking, and Smart rate ports. The customer asks about Aruba 5400R z 12 switches.

  Which Aruba Switch model would better meet the customer's requirements?

  A. 2530

  B. 2930F

  C. 3810

  D. 8400

  Correct Answer: C

• Question 59:

  A network administrator enters this command:

  Switch(config)# aaa authorization user-role enable

  How does this affect device authentication?

  A. The local manager and operator accounts will no longer work unless they are associated with a user role on the switch.

  B. Authenticated devices must receive their dynamic settings, such as VLAN ID and ACLs, from the RADIUS server Access-Accept.

  C. Authenticated devices will be defined proper access if the RADIUS server sends any VSA except the user-role VSA

  D. Role-based mode will no longer be available with tunneled node to prevent conflicts with the AAA user roles.

  Correct Answer: B

• Question 60:

  A company wants to implement RADIUS authentication of all managers who log in to AOS-Switches via SSH. The RADIUS server also sends VSAs that indicate which commands users can enter, and switches must honor these.

  What must the administrator do to meet the company's requirements?

  A. Set the command access level to manager mode; also set RADIUS for aaa authentication ssh login and aaa authentication ssh enable.

  B. Set RADIUS for aaa authentication ssh login, also enable authentication privilege-login mode, which allows the switch to accept all RADIUS VSAs.

  C. Set command authorization to RADIUS, also set RADIUS for aaa authentication ssh login and aaa authentication ssh enable.

  D. Set RADIUS for aaa authentication ssh enable, which allows the switch to accept all RADIUS VSAs.

  Correct Answer: B
