HP HP Certifications HPE6-A45 Questions & Answers

• Question 141:

  A network administrator needs to create a QoS policy on an AOS-Switch. What is one component that the administrator must create before the policy?

  A. an extended IPv4 ACL

  B. a traffic behavior

  C. an extended MAC ACL

  D. a traffic class

  Correct Answer: D

• Question 142:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2

  

  Switch-1 and Switch-2 are configured to provide VRRP in VLAN 2. The default gateway for VLAN 2 is set to the VRRP virtual IP. Client-1 in VLAN 2 cannot ping its default gateway.

  Based on the exhibits, what can administrators determine?

  A. The VRRP preempt delay time has not yet expired, and administrators should try to ping the gateway again in several minutes.

  B. Switch-1 and Switch-2 have the same virtual router ID. The conflict interferes with connectivity.

  C. Preempt mode is enabled on both Switch-1 and Switch-2, so the Master role continues to alternate between them, and the pings go astray.

  D. This is the expected behavior, and Switch-1 should still be able to route traffic for Client-1.

  Correct Answer: A

• Question 143:

  Which switches can be deployed in a mesh topology for backplane stacking?

  A. Aruba 2920 switches

  B. Aruba 2930F switches

  C. Aruba 2930M switches

  D. Aruba 3810 switches

  Correct Answer: D

• Question 144:

  Refer to the exhibits.

  Exhibit 1

  

  Exhibit 2

  

  Exhibit 1 shows a portion of the BGP routing table when the BGP solution was first deployed. Exhibit 2

  shows the same portion at the current time. What can explain the current state?

  A. Due to changes in the private network, Switch-1 can no longer reach 192.168.2.1.

  B. Switch-1 can no longer reach ISP 1 at 192.168.1.1.

  C. Due to changes at ISP 1, Switch-1 now selects a different best route.

  D. An administrator has applied a route map on Switch-1 that filters advertised routes.

  Correct Answer: C

• Question 145:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2 Switch-1 has a power issue that causes it to fail. When Switch-1 comes back up, endpoints lose connectivity for a few minutes. The network administrator decides to enter this command on Switch-1:

  

  Switch-1 (config)# vlan 10 vrrp vrid 10 preempt-delay-time 120

  Exhibit 2 shows the VRRP configuration just after the change. What is the effect of this change?

  A. Switch-1 and Switch-2 both become Master in their own VRRP virtual router due to the delay timer mismatch. The mismatch must be fixed.

  B. Switch-1 now waits to take over as Master if it fails and recovers. This should prevent the connectivity issue from occurring again.

  C. Switch-1 experiences an internal error in the VRRP process. This error causes Switch-2 to take over as Master for VLAN 2.

  D. Switch-1 continues to act as it did before the preempt delay time was set. Administrators must plan additional changes to fix the issue.

  Correct Answer: C

• Question 146:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2

  

  In the exhibits, VLAN 20 under a device name indicates that the device is configured with that VLAN. The exhibits also indicate whether VLAN 20 is statically configured on each link, either as an untagged or a tagged VLAN. If the link has no label, VLAN 20 is not statically configured on that link.

  A network administrator needs to deploy AOS-Switches that use port-based tunneled node. The plan calls for tunneled-node endpoints to be assigned to VLAN 20 and for the Aruba Mobility Controller to handle the tunneled-node traffic at Layer 2.

  Which exhibit shows the correct plan for VLAN 20 in the wired infrastructure?

  A. A

  B. B

  C. C

  D. D

  Correct Answer: B

• Question 147:

  Network administrators need to track when traffic matches deny entry in an ACL applied to a port. They

  want the alert to be sent to a syslog server that is already set up to send logs.

  What should administrators do to enable alerts?

  A. Specify the log option for the ACL entry, and enable ACL debugging.

  B. Set the debug destination to session, and enable ACL debugging.

  C. Enable ACL debugging, and enable SNMP port security traps.

  D. Specify the log option for the ACL entry, and enable SNMP port security traps.

  Correct Answer: D

• Question 148:

  Refer to the exhibit.

  

  An AOS-Switch has an extended ACL that is applied to several physical interfaces.

  -New interfaces have been brought online.

  -The ACL has been applied to them as well.

  A network administrator sees the output in the exhibit and is concerned that the switch will reach the limit for rules.

  What can the administrator do to address this concern?

  A. Resequence the ACL with less space in between the entries.

  B. Enable ACL grouping, and apply ACLs as shared ACLs.

  C. Reconfigure the ACL as a standard ACL, and then reapply it.

  D. Remove static ACLs, and have the RADIUS server send dynamic ACLs.

  Correct Answer: A

• Question 149:

  Refer to the exhibit.

  

  A company requires distribution layer switches that can provide Layer 2 and Layer 3 redundancy. The exhibit shows the proposal for these switches.

  Which change to the proposal will help meet the company's requirements?

  A. The proposed switches should be replaced with switches such as the Aruba 2930M to support the backplane stacking technology.

  B. VRRP should be implemented instead of backplane stacking to support the Layer 3 redundancy requirements.

  C. Link aggregations should be established without LACP to support the Layer 2 redundancy requirements and backplane stacking limitations.

  D. The proposed switches should be replaced with switches that support VSF to support the required distance between stack members.

  Correct Answer: C

• Question 150:

  Refer to the exhibit.

  

  A company wants to change Area 1 shown in the exhibit from a stub area to a totally stub area. What will be one effect of this planned change?

  A. Routing devices within Area 0 will temporarily lose adjacency with each other.

  B. Switch-1 and Switch-2 will adjust the cost with which they advertise area 1 traffic in the backbone.

  C. Some traffic from Area 1 to other areas will no longer follow the lowest cost path.

  D. Endpoints within Area 1 will no longer be able to reach endpoints in other areas.

  Correct Answer: C
