Question #1
Which statement is correct regarding ACLs and TCAM usage?
- AApplying an ACL to a group of ports consumes the same resources as specific ACE entries
- BUsing object groups consumes the same resources as specific ACE entriesMost Voted
- CCompression is automatically enabled for ASIC TCAMs on AOS-CX switches
- DApplying an ACL to a group of VLANs consumes the same resources as specific ACE entries
Correct Answer:
B
B

Utilization of object groups in ACLs does indeed consume the same resources as deploying specific Access Control Entries (ACE). This is particularly relevant when configuring ACLs to optimize resource use without altering the granularity of control provided by the entries themselves. It ensures efficient use of TCAM resources in a network switch, which is critical for maintaining desired performance levels during data packet filtering and forwarding decisions.

Question #2
What is correct regarding rate limiting and egress queue shaping on AOS-CX switches?
- AOnly a traffic rate and burst size can be defined for a queueMost Voted
- BLimits can be defined only for broadcast and multicast traffic
- CRate limiting and egress queue shaping can be used to restrict inbound traffic
- DRate limiting and egress queue shaping can be applied globally
Correct Answer:
A
A

Egress queue shaping in AOS-CX switches is precisely about setting a maximum bandwidth and a defined burst size for each priority queue. This setup helps in managing the queue's traffic, ensuring no single queue can monopolize bandwidth resources, which potentially starves lower priority queues. It's crucial to understand that these settings are specifically to regulate how much data is buffered before being sent according to the queue's assigned maximum rate, which directly aids in controlling traffic bursts and maintaining efficient network performance under diverse traffic conditions.

Question #4
A company has implemented 802.1X authentication on AOS-CX access switches, where two ClearPass servers are used to implement AAA. Each switch has the two servers defined. A network engineer notices the following command configured on the AOS-CX switches: radius-server tracking user-name monitor password plaintext aruba123
What is the purpose of this configuration?
What is the purpose of this configuration?
- AImplement replay protection for AAA messages
- BDefine the account to implement downloadable user roles
- CSpeed up the AAA authentication processMost Voted
- DDefine the account to implement change of authorization
Correct Answer:
C

Question #5
A company has an existing wireless solution involving Aruba APs and Mobility controllers running 8.4 code. The solution leverages a third-party AAA solution. The company is replacing existing access switches with AOS-CX 6300 and 6400 switches. The company wants to leverage the same security and firewall policies for both wired and wireless traffic.
Which solution should the company implement?
Which solution should the company implement?
- ARADIUS dynamic authorization
- BDownloadable user roles
- CIPSec
- DUser-based tunnelingMost Voted
Correct Answer:
A
A

The correct focus should be on RADIUS dynamic authorization because it allows for centralized control over user access to network resources, supporting consistency across both wired and wireless domains within the company's infrastructure. This method effectively links with third-party AAA solutions, unlike User-based Tunneling (UBT), which typically requires ClearPass, emphasizing the versatility of RADIUS in diverse network environments. Therefore, the use of dynamic authorization directly aligns with the desire to maintain uniform security policies across the network without being restricted to specific vendor solutions.
