What is a primary benefit of BSS coloring?
Correct Answer:C
BSS coloring is a mechanism that helps identify the BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. on the same channel and differentiate them from other BSS on the same channel12. Each BSS is assigned a color code, which is a 6-bit value that is carried in the PHY header of the Wi-Fi frames12. By using BSS coloring, the APs and clients can reduce the threshold for interference detection and avoid unnecessary backoff or
retransmissions when they detect frames from other BSS with different colors12. This can improve the spectral efficiency and throughput of the network12. The other options are incorrect because they do not describe the primary benefit of BSS coloring.
What is used to retrieve data stored in a Management Information Base (MIS)?
Correct Answer:A
The correct answer is A. SNMPv3.
SNMPv3 is a protocol that is used to retrieve data stored in a Management Information Base (MIB), which is a database of managed objects in a network. SNMPv3 provides security and access control features that are not available in earlier versions of SNMP. SNMPv3 can also use encryption to protect the data from unauthorized access or modification.
According to the Aruba Certified Professional – Campus Access document1, one of the skills that this certification validates is:
✑ Implement and Analyze the output from common network monitoring tools
The document also mentions that the candidate should have a distinguished understanding of different protocols across vendors, which implies that they should be familiar with SNMPv3 and how it can be used to access MIB data.
You are building a configuration in Central that will be used for a standardized network design for small sites for your company, you want to use GUI configuration for gateways and Aps, while template configuration for switches. You need to align with Aruba best practices.
Which set of actions will satisfy these requirements?
Correct Answer:C
This is because option C shows how to create a single group in Central with different configuration methods defined for each device type. For example, you can create a group with the name Group1, and within this group, you can enable template-based configuration method for switches and UI-based configuration method for Instant APs and Gateways. Aruba Central identifies both these groups under a single name (Group1). If a device type in the group is marked for template-based configuration method, the group name is prefixed with TG (TG Group1). You can use Group1 as the group ID for workflows such as user management, monitoring, reports, and audit trail2.

With the Aruba CX switch configuration, what is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation?
Correct Answer:A
Active Gateway is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation. Active Gateway is a feature that allows both VSX peers to act as active gateways for different subnets, eliminating the need for VRRP or other first-hop redundancy protocols. Active Gateway also provides fast failover and load balancing for L3 traffic across the VSX peers. The other options are incorrect because they are either not recommended or not supported by Aruba CX VSX.
