HPE6-A45 sample questions

Question 1

Refer to the figure.

A network administrator sets up prioritization for an application that runs between Device 1 and Device 2. However, the QoS for the application is not what the administrator expects. How can the administrator check if the network infrastructure prioritizes traffic from Device 1 and Device 2?

Accepted Answer

Run a packet capture on Device 2, run the application, and look in the packet capture for a high value DSCP in the IP header.

Answer

Set up RMON alarms on the switches that trigger when a high number of packets are dropped. Then, run the application and check for the alarm.

Answer

Clear interface statistics on the switches. Then, run the application and check the interface queue statistics for the switch-to-switch links.

Answer

Run a packet capture on Device 1, run the application, and look in the packet capture for a high value DSCP in the IP header.

Question 2

The figures 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?

Accepted Answer

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

Answer

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

Answer

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

Answer

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

Question 3

An AOS-Switch implements tunneled node. Which benefit does the PAPI enhanced security key provide?

Accepted Answer

It authenticates control traffic between the switch and its Mobility Controller.

Answer

It validates the signature for firmware pushed to the switch dynamically

Answer

It encrypts traffic sent and received by tunneled-node endpoints.

Answer

It provides an extra layer of authentication for endpoints on tunneled-node ports.

Question 4

Refer to the figure.

A network administrator needs to deploy AOS-Switches that implement port-based tunneled node. Their Aruba controller has IP address 10.1.10.5/24. The architect has assigned tunneled-node endpoints to VLAN 20. What is one issue with the current configuration planned for VLAN 20 on the switch?

Accepted Answer

VLAN 20 must not enable jumbo frames.

Answer

VLAN 20 must have GRE enabled on it.

Answer

VLAN 20 cannot have an IP address.

Answer

VLAN 20 must have an IP address in the same subnet as the controller.

Question 5

OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is not configured with a range for Area 1. Which type of issue occurs due to this mismatch?

Accepted Answer

The ABRs create a discontinuous area and disrupt intra-area routing between devices within Area
1.

Answer

The ABR core would send Area 1 traffic destined to the other switch through an access switch.

Answer

The ABRs lose adjacency entirely and cannot route traffic between each other at all.

Answer

The ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.

Question 6

The company wants to minimize congestion on Link 1. Which spanning tree implementation meets this goal?

Accepted Answer

Instance 1 = VLANs 4,6 Instance 2 = VLANs 5,7
Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1
Switch 3 instance 1 priority = 0 Switch 3 instance 2 priority = 1

Answer

Instance 1 = VLANs 4-5 Instance 2 = VLANs 6-7
Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1
Switch 3 instance 1 priority = 1 Switch 3 instance 2 priority = 0

Answer

Instance 1 = VLANs 4,6 Instance 2 = VLANs 5,7
Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1
Switch 3 instance 1 priority = 1 Switch 3 instance 2 priority = 0

Answer

Instance 1 = VLANs 4-5 Instance 2 = VLANs 6-7
Switch 2 instance 1 priority = 0 Switch 2 instance 2 priority = 1
Switch 3 instance 1 priority = 0 Switch 3 instance 2 priority = 1

Question 7

Refer to the figure.

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?

Accepted Answer

Define edge ports as untrusted DHCP ports.

Answer

Define trk1 as a trusted DHCP port.

Answer

Define an authorized DHCP server.

Answer

Enable ARP protection.

Question 8

A network administrator configures connection rate filtering on interface 1 with the throttle action. Device 1 crosses the threshold and triggers the action. What does the switch do?

Accepted Answer

It temporarily drops all IP traffic from Device 1 only.

Answer

It temporarily drops all IP traffic on interface 1.

Answer

It drops all IP traffic from Device 1 until the host is manually unblocked.

Answer

It drops all IP traffic on interface 1 until the interface is manually unblocked.

Question 9

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

Accepted Answer

It must initiate a graceful restart.

Answer

It must run the shortest path first algorithm.

Answer

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

Answer

It must re-establish adjacency with its Designated Router.

Question 10

Two AOS-Switches are directly interconnected. The network administrator wants to prevent broadcast storms and other Layer 2 issues that could occur if there is physical damage to a cable. Which technology should the administrator implement on the connected switch interfaces?

Accepted Answer

Unidirectional Link Detection (UDLD)

Answer

MAC Lockdown

Answer

Bidirectional Forwarding Detection (BFD)

Answer

Spanning Tree Root Guard
