HPE6-A45 sample questions

Question 1

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 2

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 3

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 4

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 5

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 6

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 7

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

Question 8

Refer to the figure.

The routing switches shown in the figure 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?

Accepted Answer

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

Answer

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

Answer

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

Question 9

Which benefit is provided by MD5 authentication for BGP?

Accepted Answer

It validates that BGP messages arrive from an authorized device.

Answer

It verifies that received BGP routes have valid next hop IP addresses.

Answer

It enables users to authenticate to a server across BGP AS boundaries.

Answer

It protects BGP routing information from eavesdroppers.

Question 10

Refer to the figures.

The VoIP phone connects, authenticates successfully, and is dynamically assigned to tagged VLAN 6. The endpoint connected to the phone does not authenticate but starts to send untagged traffic. How does the switch handle this traffic?

Accepted Answer

It relays the traffic to the RADIUS server for authentication

Answer

It forwards the traffic in VLAN 5.

Answer

It forwards the traffic in VLAN 6.

Answer

It drops the traffic.
