HP Aruba Certified Campus Access Mobility Expert Written Exam Sample Questions (Q25-Q30):

NEW QUESTION # 25
Which statement about the AOS-CX VOQ feature is true?

Answer: B

Explanation:
Comprehensive and Detailed Explanation (Verified Extract from HPE Aruba Networking Switching Documentation) VOQ (Virtual Output Queuing) is a hardware-based queuing mechanism used in the ArubaOS-CX architecture to prevent head-of-line blocking and minimize packet drops in high-throughput environments.
How VOQ Works:
* Each ingress port maintains a separate queue for every egress port in the system.
* When a packet arrives, it is placed in the ingress buffer corresponding to its destination egress port.
* This structure ensures that traffic destined for one congested egress port does not block packets heading to other ports.
This architecture is critical in high-speed modular switches and aggregation cores (such as the Aruba 8400 and 10000 Series), allowing the fabric interconnect to forward traffic efficiently without dropping packets due to port congestion.
ArubaOS-CX Technical Extract:
"Virtual Output Queuing (VOQ) provides per-egress-port queuing at ingress buffers, preventing head-of-line blocking and ensuring high throughput across the switch fabric. Each ingress queue corresponds to a specific egress port, allowing packets to be transmitted as soon as the egress port becomes available." Option Analysis:
* A. Incorrect - Refers to priority marking (QoS), not VOQ operation.
* B. Correct - VOQ provides ingress buffers with queues for each egress port, reducing dropped packets and head-of-line blocking.
* C. Incorrect - VOQ is not related to LACP or VSX link aggregation.
* D. Incorrect - VOQ does not dynamically allocate egress buffer space; it segregates ingress queues per egress destination.
Final Verified answer: B

NEW QUESTION # 26
Exhibit.

A university runs its own TV station in the city The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications in order to improve the bandwidth consumption. PlM sparse Mode and IGMP snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way While troubleshooting the network administrator saves the packet captures shown in the exhibit and concludes that all users even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?

Answer: A

Explanation:
Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is transmitted over the air by converting multicast streams into unicast streams to the clients that need them.
This reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds by all users.

NEW QUESTION # 28
A customer is installing CX 6300 switches, mobility gateways, and AP-635s.
The customer's VoIP system uses both wired and wireless handsets.
The handsets are configured to mark voice traffic using a DSCP value of 46.
The wireless handsets connect to a bridged SSID using WPA3-SAE.
What will allow the switch to honor the QoS mark set by the handset?

Answer: A

Explanation:
Comprehensive and Detailed Explanation (Verified Extract from HPE Aruba Networking Switching Documentation) In Aruba AOS-CX switching environments, Quality of Service (QoS) allows the switch to prioritize certain types of traffic such as voice, video, or real-time applications.
When a connected endpoint (such as a VoIP phone or wireless handset) marks packets with DSCP = 46 (Expedited Forwarding for voice), the switch must trust these markings to maintain end-to-end traffic prioritization.
Key Concept: Trust Boundary
By default, Aruba switches do not trust incoming DSCP or 802.1p markings from end devices for security reasons.
To allow the switch to accept and act on these values, the QoS trust DSCP feature must be explicitly enabled on the relevant interface or globally.
Official Aruba AOS-CX Extract:
"The qos trust dscp command enables the switch port to honor the Differentiated Services Code Point (DSCP) markings received from connected devices. When trusted, packets maintain their QoS priority as they traverse the switch fabric." When wireless handsets connect to a bridged SSID, their traffic is bridged locally at the access switch - meaning the switch sees the traffic directly from the AP. If the handset marks the packet with DSCP 46, enabling QoS trust DSCP ensures that the switch preserves that marking and applies the appropriate voice priority queue treatment.
This configuration ensures end-to-end QoS consistency between the wireless AP, mobility gateway, and wired switch.
Option Analysis:
* A. Incorrect - "Voice Wi-Fi Multimedia Share" is not a valid Aruba configuration feature; WMM shares QoS mapping but not DSCP trust.
* B. Incorrect - UCC (Unified Communications and Collaboration) enhances call visibility and diagnostics, not DSCP trust or QoS marking.
* C. # Correct - Enables the switch to trust and honor DSCP markings (such as DSCP 46) received from endpoints or bridged SSIDs.
* D. Incorrect - WMM (Wi-Fi Multimedia) is required for prioritization over wireless links, but since this is a bridged SSID, the DSCP markings must be honored at the switch, not just the AP.
# Final Verified answer: C

NEW QUESTION # 29
A deployment using AP-635S is connectedto a stack of CX 6300s as shown.

The output of the snow LACPinterfaces shews the following:

What is causing this issue?

Answer: B

Explanation:
In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output,it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.
