• A. set access ssh
• B. enable remote-access
• C. crypto key generate rsa
• D. ssh enable

Answer: C

Explanation:
The crypto key generate rsa command creates an SSH key pair, allowing secure remote login to the switch using SSH.

NEW QUESTION # 104
A company has a third-party AAA server solution. The campus access layer was just upgraded to AOS-CX switches that perform access control with MAC-Auth and 802.1X. The company has an Aruba Mobility Controller (MC) solution for wireless, and they want to leverage the firewall policies on the controllers for the wired traffic.
What is correct about how the company should implement a security solution where the wired traffic is processed by the MCs?

• A. Implement local user roles with a gateway role defined on the AOS-CX switches
• B. Implement downloadable user roles with a device role defined on the AOS-CX switches and MCs
• C. Implement standards-based RADIUS VSAs to pass policy information directly to the AOS-CX switches and MCs
• D. Implement downloadable user roles with a gateway role defined on the AOS-CX switches

Answer: A

Explanation:
Because it use 3rd party aaa server.

NEW QUESTION # 105
You want to upgrade a re-provisioned Mobility Gateway that is currently using LACP. What feature will allow you to do this without removing interfaces from LAG?

• A. LACP passive
• B. LACP static
• C. LACP fallback
• D. LACP active

Answer: C

Explanation:
LACP fallback allows an interface that is part of a LAG to continue forwarding traffic even when LACP negotiation temporarily fails -- such as during a Mobility Gateway reboot or upgrade.
This enables the upgrade to proceed without removing interfaces from the LAG, since fallback mode keeps the link operational until LACP becomes available again.

NEW QUESTION # 106
Which tool is best suited for diagnosing high packet loss in a wired network?
Response:

• A. Wireshark
• B. NetEdit
• C. Aruba AirWave
• D. Ping

Answer: A

NEW QUESTION # 107
Which CLI command verifies the assigned IP addresses on all interfaces?

• A. show ip address-table
• B. show interfaces ip
• C. show ip interface brief
• D. show vlan ip

Answer: C

Explanation:
The show ip interface brief command displays all interfaces, showing their IP addresses, status, and operational state, helping in troubleshooting connectivity issues.

NEW QUESTION # 108
You have applied the following OSPF configuration but are not seeing any output from the command below. What is the reason for this?

• A. A VRF wasn't specified in the show command.
• B. A different OSPF process ID is used on each switch.
• C. OSPF interfaces are passive by default.
• D. A loopback interface hasn't been configured on Agg-2.

Answer: B

Explanation:
Each switch is running OSPF under the same VRF but using different OSPF process IDs (Agg-1 uses process 1, Agg-2 uses process 2).
On Aruba CX, OSPF adjacencies only form between routers using the same OSPF process ID within the same VRF, so the devices never establish a neighbor relationship.

NEW QUESTION # 109
A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile based on best practices. Why do they have an equal split of their 260 APs across the primary and secondary gateway clusters?

• A. The primary gateway cluster is up, but some APs cannot reach the secondary gateway cluster.
  These APs would connect to the secondary gateway cluster
• B. The secondary gateway cluster is heterogeneous
• C. The secondary gateway cluster is homogeneous
• D. The primary gateway cluster is up, but some APs cannot reach the primary gateway cluster.
  These APs would connect to the secondary gateway cluster

Answer: D

NEW QUESTION # 110
Refer to the exhibit from an HPE Aruba Networking CX6000:

Two CX 6000 switches are configured with the same configuration for LAG 1. What needs to be done to remove the LACP block state?

• A. On both of the switches, change the LACP timeout to short
• B. Change the LACP mode from passive to active on one of the switches
• C. On one of the switches, change the LACP mode to passive
• D. Change the LACP mode from passive to static on one of the switches

Answer: B

Explanation:
LACP (Link Aggregation Control Protocol) modes can be active or passive. When two switches are both configured in passive mode, no LACP packets are initiated, causing the link aggregation to fail or go into a block state.
Changing one side from passive to active causes that switch to initiate LACP negotiation, resolving the block state.
Changing to static mode disables LACP negotiation, which is not recommended unless both sides are static.
Changing timeout does not solve LACP block issues caused by mode mismatches.
Therefore, changing one switch's LACP mode from passive to active is necessary to resolve the block.

NEW QUESTION # 112
You have applied the following OSPF configuration but are seeing the output from the command below. What is the reason for this?

• A. A loopback interface hasn't been configured on Agg-2
• B. A different OSPF process ID is used on each switch
• C. OSPF interfaces are passive by default
• D. A Layer-3 interface has not been associated with a VRF

Answer: D

• A. Aruba CX 8400
• B. Aruba CX 6200
• C. Aruba CX 10000
• D. Aruba CX 6300

Answer: C

Explanation:
The Aruba CX 10000 is built with Pensando SmartNIC technology, enabling distributed security, firewalling, and microsegmentation. It allows per-port security enforcement without traditional external firewalls.

NEW QUESTION # 114
Your company needs to run BGP in a multi-homed configuration to two ISPs, advertising a block of public address space you own. Which AS number would be an example of a suitable number?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: C

NEW QUESTION # 115
Which CLI command assigns a DSCP value to a traffic class in an Aruba CX QoS policy?

• A. set traffic-class dscp 46
• B. qos dscp 46
• C. ip qos dscp 46
• D. class-map DSCP46 match dscp 46

Answer: A

Explanation:
The class-map command defines traffic classification rules, allowing specific DSCP-marked traffic to be grouped for priority handling in QoS policies.

NEW QUESTION # 116
You have run a script to configure a new VLAN on a CX switch, but are receiving a '404 - Not Found' HTTP response code.
What do you need to do to resolve the issue?

• A. Send a POST request to the /rest/v1/login resource.
• B. Enable the switch REST API in read/write mode.
• C. Specify the /rest/v1/system/vlan URI in the request.
• D. Correct syntax error contained in the data payload.

Answer: C

Explanation:
When receiving a '404 - Not Found' HTTP response while attempting to configure a VLAN via REST API, the most common cause is specifying an incorrect URI endpoint. The correct approach is to specify the exact resource path for VLAN configuration, which is /rest/v1/system/vlan. Without the correct URI, the API will return a 404 error indicating the resource is not found.
Sending a POST request to login is necessary but not related to 404 after login.
Syntax errors in payload lead to 400-series errors but usually not 404.
Enabling REST API read/write is important but would result in different errors.

• C. This indicates a security issue. The client with a MAC address ending with 37:18:0d is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network
• D. There is a roaming issue. Enable Fast Roaming 802.11r and OKC to resolve the issue

Answer: A

NEW QUESTION # 118
Which CLI command is used to reset an Aruba CX switch to factory defaults?

• A. erase startup-config
