HPE6-A45 Online Practice Questions and Answers

What must an OSPF router do to ensure nonstop routing should a standby member take over as commander when the original VSF commander fails?

A. It must run the shortest path first algorithm.

B. It must participate in a new election for the Designated Router.

C. It must initiate a graceful restart.

D. It must re-establish adjacency with its Designated Router.

Refer to the exhibit.

The routing switches shown in the exhibit run OSPF on the links between each other. The commander in the Switch-1 VSF fabric goes down. Traffic is disrupted for several seconds.

What should a network administrator do to support a faster failover in a similar situation?

A. Configure echo mode BFD on the VLAN that connects Switch-1 and Switch-2.

B. Add VRRP on the VLAN between Switch-1 and Switch-2.

C. Configure graceful restart, or nonstop OSPF, on Switch-1 and Switch-2, with a proper timer.

D. Create a redundant virtual link between Switch-1 and Switch-2.

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

Two AOS-Switches connect on VLAN 10 in OSPF Area 1, which is defined as a stub area on both.

Which mismatch can cause OSPF routers to lose adjacency?

A. The administrator adds the backbone area to just one of the routers.

B. The administrator enables graceful restart, or nonstop switching, on just one of the routers.

C. The administrator enables jumbo frames on VLAN 10 on just one of the routers.

D. The administrator adds the no-summary option to Area 1 on just one of the routers.

Refer to the exhibit.

Switch-2, Switch-5, and Switch-6 currently have many OSPF routes to Area 1 networks. The network administrator wants to replace these routes with a single aggregated route to 10.1.0.0/16 on each switch.

Where should the administrator specify the 10.1.0.0/16 range?

A. in the Switch-2 OSPF Area 2 configuration

B. in the Switch-1 OSPF Area 0 configuration

C. in the Switch-1 OSPF Area 1 configuration

D. in the Switch-2, Switch-5, and Switch-6 OSPF global configuration

Refer to the exhibit.

The company wants the fastest convergence and best load sharing of traffic over the links between Switch1 and the VSF fabric.

Which technology should the network administrator implement on these links?

A. RPVST+

B. MSTP

C. loop protection

D. LACP

A company starts to have issues with too many rules in the dynamic ACLs applied to AOS-Switch ports. Administrators decide to remove some of the common rules from the dynamic ACLs and enforce them in an ACL applied to the users' VLAN instead.

What is one rule that administrators should keep in mind to ensure that the new ACLs control traffic as they expect?

A. ACLs applied to VLANs cannot control ICMP traffic, do the dynamic ACLs must include the ICMP rules.

B. Administrators should add an explicit deny at the end of the dynamic ACLs, so traffic will hit VLAN ACL.

C. Traffic must be permitted by both the dynamic ACL and the VLAN ACL in order to be permitted.

D. If a port supports multiple clients, every dynamic ACL applied to one client filters traffic for all clients.

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

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.

A network administrator needs to control traffic based on Ethertype and Class of Service. What should the administrator configure for this purpose?

A. both a standard IP ACL and a standard MAC ACL

B. both a standard IP ACL and an extended MAC ACL

C. an extended IP ACL only

D. an extended MAC ACL only
