Question 1

You have physical access to an Aruba CX-Switch with unknown/lost credentials. What are the possible steps to rebuild the credentials? (Select two.)



Answer : B, E

To regain access to an Aruba CX switch when credentials are unknown or lost, one can press and hold the clear button, then power cycle the switch to reset the password. Additionally, using the boot profile 0 at the boot loader menu can be used to bypass the current startup configuration, which may include the unknown credentials.


Question 2

What change does a client make when it roams from one access point to another in a WLAN?



Answer : A

When a client roams from one access point to another, it must change the destination MAC address on its 802.11 frames to match the new access point to which it is associated. The SSID does not change since it is typically consistent across an entire WLAN, and the default gateway remains the same as long as the client stays within the same IP subnet. The association to a new access point involves updating the destination MAC address in the frames that the client sends.


Question 3

Which three channels can be used simultaneously in a 2.4GHz WLAN environment while avoiding any co-channel interference?



Answer : A

In a 2.4GHz WLAN environment, channels 1, 6, and 11 are recommended for use simultaneously to avoid co-channel interference because these channels do not overlap with each other. Each of these channels is separated by enough frequency space to ensure that the signals do not interfere, which is not the case with other channel combinations.


Question 4

Which type of device type and group persona is required to manage a Microbranch environment?



Answer : B

In the context of Aruba networks, a Microbranch environment is managed using a group persona that aligns with the functionality required. ArubaOS 10 Branch Gateway Group Persona would be the correct device type and group persona for managing a Microbranch environment, as it would provide the necessary features and controls for branch networking requirements.


Question 5

Which Protocol Data Unit (PDU) represents the network layer PDU?



Answer : A

In the context of the OSI model, the network layer is responsible for packet forwarding including routing through intermediate routers. Hence, the network layer PDU is known as a packet.


Question 6

You are in a meeting with a customer where you are asked to explain how the network redundancy feature VRRP works. What is the correct statement for this feature?



Answer : B

Virtual Router Redundancy Protocol (VRRP) is a network protocol that provides automatic assignment of available Internet Protocol (IP) routers to participating hosts. VRRP sends its messages over multicast for communication among routers for the election process of the master and advertisement of the virtual IP address.


Question 7

What information is required when using the ClearPass self-service registration page to generate a Multiple Pre-Shared Key (MPSK) for headless devices?



Answer : B

When generating a Multiple Pre-Shared Key (MPSK) for headless devices using the ClearPass self-service registration page, the MAC address of the device is required. MPSK associates a unique PSK with the MAC address of a device, providing a way to authenticate devices that may not have a user interface.
