HP HP Certifications HPE6-A45 Questions & Answers

• Question 71:

  Refer to the exhibit.

  

  What must the network administrator do on Switch-1 to enable this switch to advertise 192.0.2.0/24 to the router at 192.168.1.1?

  A. Redistribute OSPF routes into the BGP process

  B. Enter a static route to 192.0.2.0/24 to the black hole.

  C. Enter the network 192.168.1.0/24 command in the BGP context.

  D. Enable eBGP multihop to the 192.168.1.1 neighbor.

  Correct Answer: B

• Question 72:

  A network administrator needs to set up an AOS-Switch to use port-based tunneled node for connected devices. However, the administrator wants the switch to forward traffic without tunneling if it cannot reach a tunneled-node server.

  What should the administrator do?

  A. Apply the tunneled-node profile to ports, and set the local-switching-fallback option.

  B. Make sure that the switch has an IP address on the untagged VLAN assigned to the ports.

  C. Configure a local switching profile on the Mobility Controller that acts as tunneled-node server.

  D. Set the switch to role-based tunneled node, and make sure it uses the default initial user role.

  Correct Answer: D

• Question 73:

  A network administrator can set the OSPF metric type on an AOS-Switch to Type 1 or Type 2. What is the difference?

  A. A Type 2 metric marks external routes that can be advertised in NSSAs, while a Type 1 metric marks external routes that can only be advertised in normal areas.

  B. A Type 2 metric assigns cost to a 100 Gbps link, while a Type 1 metric assigns cost 1 to all links of 100 Mbps or higher.

  C. A Type 2 metric is assigned to multiple external routes that are aggregated together, while a Type 1 metric does not permit external route aggregation.

  D. A Type 2 metric stays the same as the external route is advertised, while a Type 1 metric increments with internal OSPF link costs.

  Correct Answer: D

• Question 74:

  A company has AOS-Switches, Aruba ClearPass, and Aruba AirWave. A network administrator needs to set up a new switch with the same settings found on other switches in the company.

  Which action is likely to be the most useful to perform the task?

  A. View usage patterns on the switches on AirWave.

  B. Retrieve the running config from ClearPass.

  C. Use the configuration audit tool on AirWave.

  D. Access the Network Device view on ClearPass.

  Correct Answer: B

• Question 75:

  The security plan for AOS-Switches requires protection from incoming malware traffic: generated from a worm-or virus-infected host.

  Which feature should be implemented to provide the required protection?

  A. DHCP snooping

  B. connection-rate filtering

  C. port security

  D. proxy ARP

  Correct Answer: B

• Question 76:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2 The network administrator needs to set up BGP between the two company switches, Switch-1 and Switch

  

  2. The BGP connection does not establish.

  Based on the exhibits, what does the administrator need to do to fix the issue?

  A. Set the update source for the neighbor to the local loopback interface on each switch.

  B. Enter the network command for 10.0.0.0/24 in the router BGP mode on each switch.

  C. Enable the multihop option for the neighbor on each of the switches.

  D. Enable BGP on the interfaces that the switches use to reach each other.

  Correct Answer: A

• Question 77:

  Network administrators decide to change OSPF Area 1 to a stub area in order to solve some performance issues. No routes are redistributed into area 1.

  What is one implication of making this change?

  A. Endpoints in Area 1 will no longer be able to reach external networks.

  B. Routing devices in area 1 will no longer exchange Type 1 and Type 2 LSAs with each other.

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

  D. Routing devices in area 1 will temporarily lose adjacency while the change is made.

  Correct Answer: A

• Question 78:

  Refer to the exhibit.

  

  The access layer AOS-Switches currently run DHCP snooping on VLAN 2 and connection rate filtering on edge ports. They are at default settings for ARP protection. A network administrator then enters these commands on each of the access layer switches:

  Switch(config)# arp-protect vlan 2 Switch(config)# arp-protect

  Which behavior accurse?

  A. The switches will forward legitimate traffic and prevent ARP poisoning attacks, but interfere with connection rate filtering.

  B. The switches can now prevent ARP poisoning attacks and do not interfere with legitimate communications.

  C. The switches can prevent ARP poisoning attacks, but legitimate communications with VLAN 2 could also be disrupted.

  D. The switches will not apply ARP protection due to interference from DHCP snooping, so the commands have no effect on current behavior.

  Correct Answer: B

• Question 79:

  What is a reason to create a virtual link between two OSPF routers?

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

  B. to create a connection between two areas that are not directly connected to Area 0

  C. to permit an OSPF adjacency between two VSF fabrics

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

  Correct Answer: B

• Question 80:

  A company has AOS-Switches deployed at sites with inexperienced IT staff. The main office network administrators want to track if configurations change on branch switches.

  What should be set up for this purpose?

  A. an SNMP trap

  B. an RMON alarm

  C. an IP SLA profile

  D. an auto-config server

  Correct Answer: A
