You are setting up a customer's 15 headless loT devices that do not support 802.1X.
What should you use?

  1. Multiple Pre-Shared Keys (MPSK) Local
  2. Clearpass with WPA3-PSK
  3. Clearpass with WPA3-AES
  4. Multiple Pre-Shared Keys (MPSK) with WPA3-AES

Answer(s): A

Explanation:

MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre- shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

How do you allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45?

  1. vlan trunk allowed 100 for ports 1/45 and
  2. vlan trunk add 100 in LAG256
  3. vlan trunk allowed 100 in LAG256
  4. vlan trunk add 100 in MLAG256

Answer(s): C

Explanation:

To allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45, you need to use the command vlan trunk allowed 100 in LAG256. This will add VLAN 100 to the list of allowed VLANs on the trunk port LAG256, which is part of the inter-switch-link between VSX peers. The other options are incorrect because they either do not use the correct command or do not specify the correct port or VLAN.

Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN
10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.



What is correct about access from the servers to the Core? (Select two.)

  1. Server 1 can access the core layer via the keepalrve link
  2. Server 2 can access the core layer via the keepalive link
  3. Server 2 cannot access the core layer.
  4. Server 1 can access the core layer via both uplinks
  5. Server 1 and Server 2 can communicate with each other via the core layer
  6. Server 1 can access the core layer on only one uplink

Answer(s): D,E

Explanation:

These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question.

A large retail client is looking to generate a rich set of contextual data based on the location information of wireless clients in their stores Which standard uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP?

  1. 802.11ah
  2. 802.11mc
  3. 802.11be
  4. 802.11V

Answer(s): B

Explanation:

802.11mc is a standard that uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP. 802.11mc defines a protocol for exchanging FTM frames between an AP and a client, which contain timestamps that indicate when the frames were transmitted and received. By measuring the RTT of these frames, the AP or the client can estimate their distance based on the speed of light. The other options are incorrect because they either do not use RTT or FTM or do not exist as standards.
