HPE6-A45 Online Practice Questions and Answers

Refer to the exhibits.

Exhibit 1.

Exhibit 2.

The exhibits show the current operational state for routes on Switch-3. The company wants Switch-3 to prefer the link to Switch-1 over the link to Switch-2 for all intra-area, inter-area, and external traffic.

What can the network administrator do to achieve this goal?

A. Set the OSPF cost on VLAN 108 higher than 1 on Switch-2 and Switch-3.

B. Set the OSPF administrative distance on Switch-2 higher than 110.

C. Set the OSPF area type to normal on all of the switches in Area 1.

D. Set the cost in the OSPF Area 1 stub command higher than 1 on Switch-2.

Refer to the exhibit.

The network administrator enables DHCP snooping globally and on VLAN 2. An additional step is mandatory for DHCP snooping to operate correctly and for clients to receive DHCP settings.

What is the additional mandatory step?

A. Define trk1 as a trusted DHCP port.

B. Define an authorized DHCP server.

C. Enable ARP protection.

D. Define edge ports as untrusted DHCP ports.

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.

Refer to the exhibits. Exhibit 1 Exhibit 2

A company does not require authentication for security, but AOS-Switches are set up to use local MAC authentication (LMA) to assign the correct VLAN and priority to IP phones. IP phones and computers belong to different VLANs. Each device is supposed to connect to a specific port, but sometimes users connect their devices to the wrong ports and cannot receive access without help from IT.

How can a network administrator configure the switches to eliminate this issue?

A. Set the address limit to 2 on the switch ports that apply LMA.

B. Create a user role that applies the user VLAN, and set this role as the initial role.

C. Add the MAC addresses for computers to the myPhones MAC group.

D. Apply LMA to all edge switch ports, and set the unauth VLAN to the user VLAN.

Two 5400R AOS-Switches are OSPF neighbors. The network administrator wants routing to update as quickly as possible in the event of a failure on a neighboring switch.

Which technology should the administrator implement on the connected switch interfaces?

A. MAC Lockdown

B. Unidirectional Link Detection (UDLD)

C. Bidirectional Forwarding Detection (BFD)

D. Spanning Tree Root Guard

A network uses MSTP and has AOS-Switches at the access layer. The company wants edge ports on the

access layer switches to meet these criteria:

They prevent all rogue switches that run STP, RSTP, or MSTP from connecting to the network.

If a rogue switch connects and is then replaced by a proper endpoint, the port recovers automatically

without IT staff involvement.

How should the network administrator set up the edge ports to meet these requirements?

A. Enable loop protection with a timeout period.

B. Enable BPDU filtering.

C. Enable both root guard and BPDU protection.

D. Enable BPDU protection with a timeout period.

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

What is a reason to implement port security on an AOS-Switch?

A. to simplify provisioning for devices such as IP phones or printers

B. to enhance the security of an 802.1X solution

C. to filter traffic at the edge, based on multiple criteria in the MAC header

D. to control management access to the switch CLI based on device, as well as user credentials

Refer to the exhibit.

Both Switch-1 and Switch-2 redistribute RIP routes into OSPF. The network administrator wants routers in Area 1 to receive the redistributed routes from Switch-1 but not from Switch-2.

What should the administrator do to achieve this goal?

A. Configure Area 1 as a stub area, with no summaries on Switch-2.

B. Configure Area 1 as a stub area, and import the routes with a low metric on Switch-2.

C. Configure Area 1 as a Not So Stubby Area (NSSA) on all routing devices in Area 1.

D. Configure a subnet range for Area 1 on Switch-2, and set the no-advertise option.

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.

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

AOS-Switch runs IGMP in data-driven mode. What behavior does it exhibit?

A. It drops multicasts destined to groups that have no members

B. It preempts the querier role even if another device has higher priority

C. It floods multicasts on all ports in the VLAN if the group has at least one member

D. It disables automatic fast leave on ports that connect to a single device

What is a reason to implement PIM-DM as opposed to PIM-SM?

A. to conserve bandwidth over WAN links

B. to permit a higher density of rendevous point (RP) routers in the network core

C. to control exactly which multicast groups are routed through the network

D. to obtain the simplest setup in a network with high bandwidth

Refer to the exhibit.

A network administrator wants to prevent endpoints from spoofing the MAC address of the VLAN 2 default gateway. What should the administrator configure on Switch-1?

A. MAC lockdown of the default gateway MAC address on ports 1-20

B. MAC lockdown of the default gateway MAC address on trk1

C. default gateway MAC address as a port security authorized address on trk1

D. default gateway MAC address as a port security authorized address on ports 1-20

What is a primary use case for RPVST+ on AOS-Switches?

A. more granular load balancing than MSTP when access switches connect to two core switches

B. enhanced loop protection in an MSTP network

C. integration of AOS-Switches in a heterogeneous vendor network that uses the Cisco protocol

D. seamless integration with RSTP
