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?
A. Inclusive Multicast Ethernet Tag (IMET)
B. Ethernet over IP (EolP)
C. Generic Routing Encapsulation (GRE)
D. Static VXLAN
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.

Due to a shipping error, five (5) Aruba AP-515S and one (1) Aruba CX 6300 were sent directly to your new branch office You have configured a new group persona for the new branch office devices in Central, but you do not know their MAC addresses or serial numbers The office manager is instructed via text message on their smartphone to onboard all the new hardware into Aruba Central. What application must the office manager use on their phone to complete this task?
A. Aruba Onboard App
B. Aruba Central App
C. Aruba CX Mobile App
D. Aruba installer App
Explanation:
Aruba Installer App is a mobile app that simplifies site installations and enables network connectivity for Aruba devices. The app allows the user to scan the barcode of the device and add it to the network using Aruba Central. The app also automates importing Aruba devices into Aruba NetEdit for intelligent configuration management and continuous conformance validation
What is a primary benefit of BSS coloring?
A. BSS color tags improve performance by allowing APS on the same channel to be farther apart
B. BSS color tags improve security by identifying rogue APS and tagging them as threats.
C. BSS color tags are applied on the wireless controllers and can reduce the threshold for interference_
D. BSS color tags are applied to WI-Fi channels and can reduce the threshold tor interference
Explanation:
The primary benefit of BSS coloring is D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference. BSS coloring is a mechanism that allows Wi-Fi 6 devices to mark each frame with a color code that identifies the BSS (Basic Service Set) it belongs to. This helps differentiate between frames from different BSSs that share the same channel and avoid unnecessary collisions and backoffs. BSS coloring also introduces an adaptive threshold for interference, which means that Wi-Fi 6 devices can adjust the signal strength value that determines whether a channel is busy or not based on the current network environment. This allows for more efficient use of spectrum and higher throughput in dense scenarios12.
Your customer has asked you to assign a switch management role for a new user The customer requires the user role to only have Web Ul access to the System > Log page and only have access to the GET method for REST API for the /logs/event resource. Which default AOS-CX user role meets these requirements?
A. administrators
B. auditors
C. sysops
D. operators
Explanation:
The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource. The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the Web UI or REST API.

You need to ensure that voice traffic sent through an ArubaOS-CX switch arrives with minimal latency What is the best scheduling technology to use for this task?
A. Strict queuing
B. Rate limiting
C. QoS shaping
D. DWRR queuing
Explanation:
Strict queuing is the best scheduling technology to use for voice traffic on an AOS-CX switch. Scheduling is a mechanism that determines how packets are transmitted from different queues on an egress port. Strict queuing is a scheduling method that gives the highest priority queue absolute preference over all other queues, regardless of their size or utilization. Voice traffic should be assigned to the highest priority queue and scheduled with strict queuing to ensure minimal latency and jitter. The other options are incorrect because they are either not scheduling methods or not optimal for voice traffic.
