HP Aruba Certified Campus Access Mobility Expert Written Exam Sample Questions (Q28-Q33):

NEW QUESTION # 28
An OSPF router has learned a path to an external network by both an E1 and an E2 advertisement. Both routes have the same path cost. Which path will the router prefer?

A. Both routes will be suppressed until the path conflict has been resolved.
B. The router will use both paths equally utilizing ECMP.
C. The router will prefer the E2 path.
D. The router will prefer the E1 path.

Answer: D

Explanation:
In HPE Aruba Networking (AOS-CX and AOS-Switch) OSPF implementation, the routing behavior for external routes (Type 5 LSAs) distinguishes between two types of external advertisements:
* E1 (Type-1 external) - The total path cost is calculated as the sum of the internal cost to reach the ASBR (Autonomous System Boundary Router) plus the external cost as advertised in the LSA.
* E2 (Type-2 external) - The external cost is considered independent of the internal OSPF path cost to reach the ASBR. Thus, the metric used is only the external cost from the LSA.
When both an E1 and an E2 route exist to the same external destination, OSPF gives preference to the E1 route, regardless of metric values, because the E1 route represents a more accurate total cost to the destination (including internal OSPF cost).
Extract (as per HPE Aruba OSPF Technical Overview and AOS-CX Routing Guide):
"When both Type-1 (E1) and Type-2 (E2) external LSAs for the same destination are present, the router always prefers the Type-1 route. Type-1 routes include both internal and external costs in the total metric, while Type-2 routes use only the external cost. The E1 path is therefore considered more precise and is selected as the preferred route." This is consistent across Aruba's OSPF implementation and follows standard OSPF behavior as defined by the protocol (RFC 2328).
Therefore, when both E1 and E2 routes are available and have the same overall cost, the router will always prefer the E1 path.

NEW QUESTION # 29

A network administrator attempts to improve multicast traffic flow and performs some packet captures for validation. What can the network administrator conclude from the results?

A. The data rate increased from 6 Mbps to 300 Mbps because Dynamic Multicast Optimization (DMO) was configured.
B. The capture taken after optimization does not show a packet length because Multicast Transmission Optimization was configured.
C. The type field remains consistent because Dynamic Multicast Optimization (DMO) was configured.
D. The data rate increased from 6 Mbps to 300 Mbps because Broadcast Multicast Optimization (BCMCO) was configured.

Answer: A

Explanation:
The packet decode excerpt shows a QoS Data frame, not a multicast-control low-rate frame.
Frame control flags indicate:
* Subtype: QoS Data # This is unicast, not broadcast/multicast
* From DS bit = 1, To DS bit = 0 # Wireless unicast from AP to client
* High-rate MCS data present # Indicates optimized transmission speed
This behavior aligns directly with Dynamic Multicast Optimization (DMO).
Aruba DMO Overview - Official Behavior
ArubaOS Wi-Fi optimization guides state:
"Dynamic Multicast Optimization converts multicast packets into unicast transmissions and sends them using the highest supported data rate, improving delivery reliability and efficiency." This means:
Before DMO
After DMO
Multicast sent at lowest basic rate (e.g., 6 Mbps)
Converted to unicast # can use high PHY rates (e.g., 300 Mbps+)
High drop probability
Reliable delivery
Poor performance
Optimized throughput
The packet remaining a Data/QoS Data subtype is correct - DMO does not change the 802.11 frame Type field; it changes transmission handling and rate control.
Why the Other Options Are Incorrect
Option
Why Incorrect
A BCMCO does not exist - incorrect feature name
B Type consistency is not the key validation point - rate increase is
D Packet length always appears in frame decode; optimization never hides it
# Final Verified answer: C
The data rate increased from 6 Mbps to 300 Mbps because Dynamic Multicast Optimization (DMO) was configured.

NEW QUESTION # 30
Refer to the exhibit.

Which statement is true?

A. The client is using BSS Fast Transition
B. The client used an incorrect passphrase
C. The client is failing 802.1X authentication
D. The client performed passive scanning

Answer: C

Explanation:
The exhibit shows a series of 802.1X authentication steps with multiple "Deauthentication" frames, which indicate that the client is not successfully completing the authentication process. Since the frames show repeated attempts at authentication followed by deauthentication, this suggests that the client is failing the
802.1X authentication process, which is required for network access in a WPA2/WPA3-Enterprise security environment.

NEW QUESTION # 31
What is the recommended configuration to ensure link aggregation is consistent in a campus topology using VSX with two aggregation switches and downlinks to access switches?

A. Use the command "vsx-sync mclag-interfaces" under the VSX context.
B. Use the command "vsx-sync active-gateways" under the VSX context.
C. Use a custom LACP hash algorithm for improved load balancing.
D. Use the command "vsx-sync mclag-interfaces" from the global context.

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
The VSX synchronization feature provides per-feature synchronization from the primary to the secondary VSX peer. For multi-chassis LAGs (MC-LAGs), the command that ensures both VSX peers maintain consistent LAG interface associations and attributes is entered under the VSX configuration context:
* Command syntax: vsx-sync mclag-interfaces
* Command context: config-vsx
Description (extract): Enables VSX synchronization of VSX LAG interface associations and attributes from the primary VSX switch to the secondary peer switch.
In a campus design with two aggregation switches in a VSX pair and access switches dual-homed using MC- LAG, enabling vsx-sync mclag-interfaces under the VSX context ensures consistent LAG membership, attributes, and behavior across the pair-avoiding configuration drift and aggregation inconsistencies.

NEW QUESTION # 32
You recently added ClearPass as an authentication server to an HPE Aruba Networking Central group.
RADIUS authentication with Local User Roles (LUR) works fine Out the same access points cannot use Downloadable User Roles (DUR).
What should he corrected in this configuration to fa the issue with DUR?

A. Replace the AP's expiree digital certificate using the "crypto pki-import pem serverCert" command.
B. Add a new Enforcement Policy of type ''WEBAUTH''on ClearPass and associate it with the matching service on ClearPass
C. Add the correct values for "CPPM username" and "CPPM Password" m the authentication server configuration on HPEAruba Networking Central
D. Add the correct IP addresses or IP subnets of the Network Access Devices(NADs) under the "Devices" tabon ClearPass

Answer: D

Explanation:
For Downloadable User Roles (DUR) to function correctly with ClearPass, the Network Access Devices (NADs) need to be correctly defined in ClearPass under the "Devices" tab. This ensures that ClearPass can identify and communicate with the NADs to deliver the appropriate user roles. If the NADs are not correctly defined, ClearPass will not be able to provide the DURs to the access points for enforcement. This is a common configuration step that is required to integrate ClearPass with network devices for advanced role-based access control.
