You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?

  1. SVI, VLAN trunk allowed all on ISL in default VRF
  2. routed port in custom VRF
  3. loopback 0 and OSPF area 0 in default VRF
  4. SVI, VLAN trunk allowed all on ISL in custom VRF

Answer(s): B

Explanation:

To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF.

Which method is used to onboard a new UXI in an existing environment with 802 1X authentication? (The sensor has no cellular connection)

  1. Use the UXI app on your smartphone and connect the UXI via Bluetooth
  2. Use the Aruba installer app on your smartphone to scan the barcode
  3. Connect the new UXI from an already installed one and adjust the initial configuration.
  4. Use the CLI via the serial cable and adjust the initial configuration.

Answer(s): A

Explanation:

To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address,

etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working to a remote site connected via layer-3 All legacy devices are connected to a dedicated Aruba CX 6200 switch at each site.
What technology on the Aruba CX 6200 could be used to meet this requirement?

  1. Inclusive Multicast Ethernet Tag (IMET)
  2. Ethernet over IP (EolP)
  3. Generic Routing Encapsulation (GRE)
  4. Static VXLAN

Answer(s): A

Explanation:

VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.

Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7

  1. The AP is a remote access point.
  2. The AP is using a directional antenna.
  3. The AP is an outdoor access point.
  4. The AP is configured in Mesh mode

Answer(s): B

Explanation:

The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.
