An AOS-Switch has type of service disabled on it globally. The administrator enters:

AOS-Switch(config)# interface 1 qos trust device aruba-ap

What is the effect of this command?

Options:

A.

if the AOS-Switch is integrated with an Aruba Mobility Controller, it uses QoS settings sent by the controller to prioritize traffic sent on interface 1

if interface 1 connects to an Aruba AP, it uses the incoming DSCP and a global DSCP map to prioritize traffic received on this interface

C.

if the AOS-Switch is integrated with an Aruba Mobility Controller, it uses QoS settings sent by the controller to classify traffic received on interface 1

D.

if interface 1 connects to an Aruba AP, the switch marks all traffic received on the interface with a higher than default priority value

Exhibit 2

HPE6-A45 Question 9

Exhibit 1 shows the topology for the network. The network administrator sees the log entries shown in Exhibit 2. Which type of failure is indicated?

Options:

A.

A link between Switch-1 and Switch-2 went down. BFD detected the lost connectivity and behaved as expected.

B.

Graceful restart helper was not enabled on Switch-2, so BFD was unable to operate correctly, and the session was taken down.

C.

A hardware issue caused a unidirectional link; BFD detected the issue at Layer 2 and prevented a broadcast storm.

D.

BFD was set up incorrectly on Switch-2, so it caused Switch-2 to lose adjacency with Switch-1 rather than repair the session.

Questions 13

A company requires AOS-Switches at the campus core. The switches:

  • Will act as the default gateways for several campus VLANs
  • Must provide redundancy for their services and tolerate the loss of a link or an entire switch
  • Must recover from the failure of one of the switches within a second or less

VRRP and MSTP are proposed to meet these requirements. What is an issue with this proposal?

Options:

A.

VRRP provides redundancy against lost links but not a failed switch.

B.

VRRP provides routing redundancy but not default gateway redundancy.

C.

VRRP does not interoperate with MSTP.

D.

VRRP takes longer than a second to fail over.

Questions 14

Refer to the exhibit.

HPE6-A45 Question 14

Which issue needs to be addressed in this design?

Options:

A.

a new plan for ISP redundancy, because Switch-1 can only support one AS number, so it cannot connect to both ISP 1 and ISP 2

B.

an adjustment to the physical links, because both links to the ISP routers must be on the commander to prevent a split-brain situation

C.

a new way to provide core redundancy, because AOS-Switches in VSF fabrics can only establish BGP relationships with AOS-Switches

D.

a way to ensure that the company private network does not become a transit for traffic between ISP 1 and ISP 2

Questions 15

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 configured with this range for Area 1: 10.10.0.0/17.

Which type of issue occurs due to this mismatch?

Options:

A.

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

B.

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

C.

The ABRs advertise routes inconsistently, and they could potentially introduce a routing loop.

D.

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

Questions 17

A network administrator sets up MAC-Auth and captive portal to Aruba ClearPass on AOS-Switches. The solution seems to work for most guests. However, some guests open their browsers and are not redirected to the captive portal.

How should the administrator address the likely cause of the issue?

Options:

A.

Set the RADIUS server time window to 0 because some guest computers likely have the incorrect system time.

B.

Replace MAC-Auth on switch ports with Web-Auth because this authentication method offers more reliability with captive portal.

C.

Reconfigure the captive portal URL hash key on some of the switches, which likely have the wrong password.

D.

Replace expired certificates on the switches and set their usage to captive portal since some guests have an HTTPS homepage.
