Question 1

A company has AOS-CX switches at the access layer. The switches enforce 802.1X authentication to HPE Aruba Networking ClearPass and download roles from ClearPass. The solution has been functioning correctly. One morning, however, all users complain that they cannot connect to the network.

You are checking a switch in one affected area and see the command output shown below:

Switch-1# show port-access client 1/1/1 detail
Port Access Client Status Detail
--------------------------------

Client 2c:52:17:7f:04:c8, John Doe
============================
<-output omitted->

Authentication Details
----------------------
Status : dot1x Authenticated
Auth Precedence : dot1x - Authenticated, mac-auth – Unauthenticated
Auth History : dot1x - Authenticated, 422s ago

Authorization Details
----------------------
Role : EmployeeGroup1_3576
Status : Download Failed

What might have changed that could have caused this issue?

An admin accidentally deleted the role config on this switch and possibly other switches.
Users' credentials have expired on the ClearPass server.
A new ACL or firewall rule that filters RADIUS traffic was added to the network.
ClearPass’s HTTPS certificate expired.

Question 2

Refer to the exhibit.

CompanyA has a network with several sites. Routing devices use OSPF. CompanyA with 3,52 employees has acquired CompanyB with 1,17 employees, which has a single site; CompanyB also uses OSPF.

For the first stage of the merger, the company wants to enable connectivity between just a few specific networks in each company’s OSPF domain.

Which approach meets those needs?

Add CompanyB’s boundary routing devices to CompanyA’s OSPF area 0. Place the rest of CompanyB’s network in a new OSPF area with a single summary route configured for it.
Add all of CompanyB’s routing devices to a new OSPF area. Configure CompanyA’s boundary routing devices as ABRs for that area. On the ABRs, configure only summary routes that match the subnets of the networks that you want to advertise between areas.
Create a new VRF named “boundary” on both companies’ boundary routing devices. Establish a new OSPF process within the “boundary” VRF. Then redistribute routes between the OSPF processes on all boundary routing devices.
Create static routes to the desired CompanyB networks on CompanyA’s boundary routing devices. Redistribute static routes into OSPF. Similarly, create static routes to the CompanyA networks on CompanyB's boundary routing devices, and redistribute the routes into OSPF.

Question 3

Refer to the exhibit.

Endpoints in VLAN 14 require high-availability routing for unicast and multicast applications. These endpoints are assigned this default router IP address: 10.1.14.1. Which is a valid plan for IP settings on SVI 14 on Switch-1 and Switch-2?

Switch-1 Active gateway = 10.1.14.1 Actual IP = 10.1.14.2 Switch-2 Active gateway = 10.1.14.1 Actual IP = 10.1.14.2
Switch-1 Active gateway = 10.1.14.1 Actual IP = 10.1.14.1 Switch-2 Active gateway = 10.1.14.1 Actual IP = 10.1.14.1
Switch-1 Active gateway = 10.1.14.1 Actual IP = 10.1.14.2 Switch-2 Active gateway = 10.1.14.3 Actual IP = 10.1.14.4
Switch-1 Active gateway = 10.1.14.1 Actual IP = 10.1.14.2 Switch-2 Active gateway = 10.1.14.1 Actual IP = 10.1.14.3

Question 4

Refer to the exhibit.

Switch-1 is having an issue receiving OSPF routes. You first pinged every connected IP address, and the pings were successful. You then entered these commands on Switch-1.

What is one step for troubleshooting the issue indicated by the exhibits?

Look for differences in the OSPF area settings on interface 1/1/29 on both Switch-1 and Switch-2.
Look for differences in the OSPF timers on interface 1/1/32 on Switch-1 and the connected interface on Switch-3.
Verify that you have set a higher than default DR priority on interfaces 1/1/30 and 1/1/31 on Switch-1.
Verify that interface 1/1/29 is configured as a routing port on both Switch-1 and Switch-2.

Question 5

The command output below shows an AOS-CX switch's UBT zone status to a gateway cluster.

Which correctly describes how UBT users’ traffic will be tunneled?

All user traffic will be tunneled to the gateway at 172.16.5.11, except if that gateway is no longer accessible, in which case it will be tunneled to the gateway at 172.16.5.12.
All user traffic will be tunneled to the gateway at 172.16.5.11 until its capacity is reached at which point user traffic will be tunneled to the gateway at 172.16.5.12.
The first user will be assigned to 172.16.5.11 as their active gateway; the second user will be assigned to 172.16.5.12, and so on in a round-robin fashion.
Users will be assigned active and standby gateways based on hash algorithm; during normal operation, roughly half will tunnel traffic to 172.16.5.11 and roughly half to 172.16.5.12.

Question 6

You are onboarding a stack of HPE Aruba Networking CX 6200 switches, running software version 10.14, to HPE Aruba Networking Central. You plan to assign the switches to a template group.

What is one important guideline for the template?

It cannot include any variables.
It must include this line: vsf member 1
It cannot include static IP addresses.
It must contain VLAN 2.
