NEW QUESTION # 145
Refer to the exhibit.
You have verified that AOS-CX Switch-1 has constructed an IP-to-MAC binding table in VLANs 10-19.
Now you need to enable ARP inspection for the endpoint connected to Switch-1. What must you do first to prevent traffic disruption?
Answer: C
Explanation:
Dynamic ARP Inspection (DAI):
* ARP inspection verifies ARP packets against a trusted IP-to-MAC binding table to prevent ARP spoofing attacks.
* DHCP snooping is required to construct the IP-to-MAC binding table dynamically.
* To avoid traffic disruption, uplink ports that connect to trusted switches, DHCP servers, or routers must be explicitly configured as trusted ports for ARP inspection.
Steps to Prevent Traffic Disruption:
* Trust the Uplinks: ARP inspection must treat uplink ports as trusted to allow ARP traffic from legitimate DHCP servers and upstream switches.
* Enable DHCP Snooping: DHCP snooping must be enabled on Switch-2 to ensure consistent IP-to- MAC bindings upstream.
Why the Answer is Correct:
* Option A: Incorrect. ARP inspection on Switch-2 is important but not required first to prevent disruption on Switch-1.
* Option B: Incorrect. DHCP snooping must be enabled upstream eventually, but this alone will not stop immediate traffic disruption on Switch-1.
* Option C: Correct. Switch-1 uplinks must be trusted ARP inspection ports first to allow legitimate upstream traffic and prevent ARP disruption.
* Option D: Incorrect. Static bindings are not required if DHCP snooping is enabled, and they are manual, limiting scalability.
Conclusion:
To avoid traffic disruption, configure Switch-1 uplinks as trusted ARP inspection ports to ensure valid ARP traffic can pass upstream and downstream.
NEW QUESTION # 146
A company has HPE Aruba Networking gateways that implement gateway IDS/IPS. Admins sometimes check the Security Dashboard, but they want a faster way to discover if a gateway starts detecting threats in traffic.
What should they do?
Answer: C
Explanation:
1. The Need for Faster Threat Notifications
Admins need immediate alerts when threats are detected by the gateway ' s IDS/IPS functionality. Regularly checking the Security Dashboard is inefficient, so an automated notification system is essential for faster response times.
2. Explanation of Each Option
A). Set up Webhooks that are attached to the HPE Aruba Networking Central Threat Dashboard:
Incorrect:
Webhooks are useful for integrating alerts with third-party tools or custom workflows. However, setting up email notifications through global alert settings is faster and simpler for this purpose.
B). Use Syslog to integrate the gateways with HPE Aruba Networking ClearPass Policy Manager (CPPM) event processing:
Incorrect:
Syslog integration with CPPM is typically used for logging and correlating events, not for real-time notifications about threats.
CPPM is better suited for policy enforcement, not instant threat alerts.
C). Set up email notifications using HPE Aruba Networking Central ' s global alert settings:
Correct:
HPE Aruba Networking Central has global alert settings that allow admins to configure email notifications for specific events, such as threat detection.
This is the simplest and most effective way to ensure admins receive immediate notifications when threats are detected by the gateways.
D). Integrate HPE Aruba Networking ClearPass Device Insight (CPDI) with Central and schedule hourly reports:
Incorrect:
While CPDI integration provides enhanced device profiling, it is not directly tied to gateway IDS/IPS threat detection.
Hourly reports are not real-time notifications and would not meet the requirement for faster threat alerts.
Final Recommendation
Setting up email notifications through HPE Aruba Networking Central ' s global alert settings provides the most direct and efficient solution for immediate threat detection alerts.

NEW QUESTION # 147
An admin has configured an AOS-CX switch with these settings:
port-access role employees
vlan access name employees
This switch is also configured with CPPM as its RADIUS server.
Which enforcement profile should you configure on CPPM to work with this configuration?
Answer: B
Explanation:
To ensure that the AOS-CX switch properly assigns the " employees " role when using CPPM (ClearPass Policy Manager) as the RADIUS server, you should configure a RADIUS Enforcement profile on CPPM with the Aruba-User-Role VSA (Vendor-Specific Attribute) set to " employees " . This configuration ensures that when an endpoint authenticates, CPPM sends the appropriate role assignment to the AOS-CX switch, which then applies the corresponding policies and VLAN settings defined for the " employees " role.
Reference: Aruba ' s ClearPass documentation and AOS-CX configuration guides detail the integration and configuration of RADIUS enforcement profiles using Aruba-User-Role VSAs for role-based access control.
NEW QUESTION # 148
A company has HPE Aruba Networking APs managed by HPE Aruba Networking Central. You have set up a WLAN to enforce WPA3 with 802.1X authentication.
What happens if the client fails authentication?
Answer: D
Explanation:
When WPA3 with 802.1X authentication is enforced on an HPE Aruba Networking WLAN, the authentication process strictly adheres to security standards. Here's how the process works:
1. 802.1X Authentication Workflow in WPA3
The client must provide valid credentials (such as certificates or username/password) to authenticate with the RADIUS server via 802.1X.
If the client fails authentication (e.g., due to invalid credentials or lack of proper configuration), the 802.1X handshake fails, and the AP terminates the connection.
2. Role Assignment in WLANs
Default Role: The role assigned to authenticated clients after a successful 802.1X authentication. It is not applied to unauthenticated clients.
Critical Role: This is a fallback role applied when there are issues communicating with the RADIUS server, not when authentication fails.
Initial Role: A temporary role assigned to clients before authentication completes. However, this role is removed once the authentication process determines failure.
3. Behavior Upon Authentication Failure
In the case of an authentication failure, the client does not get assigned to any role (default, critical, or initial) because it does not meet the conditions for network access.
The client is dropped immediately, and no further communication is allowed until reauthentication is attempted.
Explanation of Each Option
A). The AP assigns the client to the WLAN ' s default role:
Incorrect: The default role applies only after successful authentication, not in case of authentication failure.
B). The AP drops the client because authentication aborts:
Correct: If the client fails authentication, the AP terminates the connection without assigning any roles.
C). The AP assigns the client to the WLAN ' s critical role:
Incorrect: The critical role is used when the AP cannot reach the RADIUS server, not when authentication fails.
D). The AP assigns the client to the WLAN ' s initial role:
Incorrect: The initial role is applied during the authentication process, but it is not retained after a failed authentication.

NEW QUESTION # 149
A company has HPE Aruba Networking APs running AOS-10 that connect to AOS-CX switches. The APs will:
. Authenticate as 802.1X supplicants to HPE Aruba Networking ClearPass Policy Manager (CPPM)
. Be assigned to the "APs" role on the switches
. Have their traffic forwarded locally
What information do you need to help you determine the VLAN settings for the "APs" role?
Answer: A
Explanation:
To determine the VLAN settings for the "APs" role on AOS-CX switches, it is crucial to know whether the APs bridge or tunnel traffic on their SSIDs. If the APs are bridging traffic, the VLAN settings on the switch need to align with the VLANs used by the SSIDs. If the APs are tunneling traffic to a controller or gateway, the VLAN settings might differ as the traffic is encapsulated and forwardedthrough the tunnel. Understanding this aspect ensures that the VLAN configuration on the switches correctly supports the traffic forwarding method employed by the APs.
