1. When implementing user-based tunneling on an AOS-CX switch, which component defines the primary and backup Aruba gateways?

Transit VLAN

Gateway role

Server group

Zone

2. A network engineer is having a problem adding a custom-written script to an AOS-CX switch’s NAE GUI. The script was written in Python and was successfully added on other AOS-CX switches.

The engineer examines the following items from the CLI of the switch:

What should the engineer perform to fix this issue?

Install the script’s signature before installing the new script

Ensure the engineer’s desktop and the AOS-CX switch are synchronized to the same NTP server

Enable trust settings for the AOS-CX switch’s SSL certificate

Remove a script that is no longer used before installing the new script

3. The AOS-CX mobile app allows a network engineer or technician to perform which tasks? (Choose two.)

Use NetEdit to manage switch configuration.

Create a stack of AOS-CX switches.

Transfer files between the switch and your mobile device.

Securely access the switch using SS

Schedule an operating system upgrade.

4. An administrator wants to track what configuration changes were made on a switch .

What should the administrator implement to see the configuration changes on an AOS-CX switch?

AAA authorization

Network Analysis Engine (NAE)

AAA authentication

VSX synchronization logging

5. An administrator is replacing the current access switches with AOS-CX switches. The access layer switches must authenticate user and networking devices connecting to them. Some devices support no form of authentication, and some support 802.1X. Some ports have a VoIP phone and a PC connected to the same port, where the PC is connected to the data port of the phone and the phone’s LAN port is connected to the switch.

Which statement is correct about this situation?

802.1X must be configured to work in fallback mode

Device fingerprinting is required for authentication

The client-limit setting for port access needs to be changed

Device mode should be implemented

6. Examine the network exhibit.

A network administrator is implementing OSPF on a VSX pair of aggregation switches: Agg1 and Agg2. VLANs 10 and 20 are connected to layer-2 access switches. Agg-1 and Agg-2 are configured as the default gateway for VLANs 10 and 20, with active gateway enabled.

What is the best practice for configuring OSPF on the aggregation switches and their connection to the Core switch?

Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active gateway for the Layer-3 VLA

Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active forwarding for the Layer-3 VLA

Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active gateway for the Layer-3 VLA

Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active forwarding for the Layer-3 VLA

7. An administrator creates an ACL rule with both the “count” and “log” option enabled .

What is correct about the

action taken by an AOS-CX switch when there is a match on this rule?

By default, a summarized log is created every minute with a count of the number of matches

Logging will not include certificate and TLS events, but counting will

The “count” and “log” options are processed by the AOS-CX switch’s hardware ASIC

The total in the “log” record and the count could contain different rule matching statistics

8. Which protocol should be configured to allow NetEdit to discover third-party devices?

SNMP

SSH

HTTPS

HTTP

9. An administrator is defining a VSX LAG on a pair of AOS-CX switches that are defined as primary and

secondary. The VSX LAG fails to establish successfully with a remote switch; however, after verification, the remote switch is configured correctly. The administrator narrows down the problem to the configuration on the AOS-CX switches.

What would cause this problem?

Local optimization was not enabled on the VSX LAG

The VSX LAG hash does not match the remote peer

The VSX LAG interfaces are in layer-3 mode

LACP was enabled in active mode on the VSX LAG

10. What is correct regarding the tunneling of user traffic between AOS-CX switches and Aruba Mobility

Controllers (MCs)?

Uses IPSec to protect the management and data traffic

Uses IPSec to protect the management traffic

Supports only port-based tunneling

Uses the same management protocol as Aruba APs

11. Examine the commands entered on an AOS-CX switch:

What is true regarding this configuration for traffic received on interface 100?

The default next-hop address supersedes the two preceding next-hop addresses

The traffic is always dropped is the next-hop addresses are unreachable

The traffic will be routed with the IP routing table entries if the next-hop addresses are unreachable

The next-hop address of 1.1.1.1 is overwritten by the next-hop address of 2.2.2.2

12. Which option correctly defines how to identify a VLAN as a voice VLAN on an AOS-CX switch?

Switch(config)# port-access lldp-group <LLDP-group-name> Switch(config-lldp-group)# vlan <VLAN-ID>

Switch(config)# port-access role <role-name> Switch(config-pa-role)# vlan access <VLAN-ID>

Switch(config)# vlan <VLAN-ID> Switch(config-vlan-<VLAN-ID>)# voice

Switch(config)# vlan <VLAN-ID> voice

13. An administrator is looking for a data center switching solution that will greatly reduce the likelihood of dropped frames when uplink congestion is experienced .

Which AOS-CX switch queuing feature meets the administrator’s needs?

FIFO

VOQ

WFQ

DWWR

14. Examine the attached exhibit.

The network administrators is trying to add a remote location as area 3 to the network shown in the diagram.

Based on current connection restrictions, the administrator cannot connect area 3 directly to area 0. The network is using AOS-CX switches.

Which feature should the administrator implement to provide connectivity to the remote location?

Not-so-stubby areas

Bidirectional forward detection (BFD)

OSPFv3

Virtual links

15. In AOS-CX switching, what determines when a frame is forwarded by the switch between the ingress and the egress port?

Egress port

Ingress port

VSX switch tables

Fabric Load Balancer

16. How should a network administrator add NAE scripts and implement NAE agents that will run on an AOS-CX switch?

Use the web interface of the NetEdit server

Use the web interface of the AOS-CX switch

Use the web interface of Aruba Central

Use the CLI of the AOS-CX switch

17. Which AOS-CX feature is used to prevent head-on-line (HOL) blocking?

VSF

WFQ

VOQ

VSX

18. Examine the following AOS-CX switch configuration:

Which access control entries would allow web traffic to the web servers 10.1.0.100 and 10.1.1.100?

permit tcp servers eq 80

permit tcp any 10.1.0.100 0.0.1.0 eq 80

permit tcp any 10.1.0.100/10.1.1.100 eq 80

permit tcp any 10.1.0.100/255.255.254.255 eq 80

19. A company has implemented 802.1X authentication on AOS-CX access switches, where two ClearPass servers are used to implement AAA. Each switch has the two servers defined.

A network engineer notices the following command configured on the AOS-CX switches:

radius-server tracking user-name monitor password plaintext aruba123

What is the purpose of this configuration?

Implement replay protection for AAA messages

Define the account to implement downloadable user roles

Speed up the AAA authentication process

Define the account to implement change of authorization

20. What is correct regarding the configuration of ACLs on AOS-CX switches?

Statements with the log keyword are always processed by the switch CP

Standard ACLs are used to match on routes when performing route distribution.

Wildcard masks are used to match on a range of IP addresses.

Numbers 100 through 199 and 2000 through 2999 are used when creating extended ACLs.
