You have deployed about 100 new Aruba 335-APs. What is required for the APs to become managed?

A. configuring a PAPI key that matches on the APs and MCs
B. installing CA-signed certificates on the APs
C. installing self-signed certificates on the APs
D. approving the APs as authorized APs on the AP whitelist

正解：D

解説：
Based on the exhibit, which shows the settings on the company's Mobility Controllers (MCs), with 'Control Plane Security' enabled and 'Enable auto cert provisioning' available, new Aruba 335-APs require approval on the MC to become managed. This is commonly done by adding the APs to an authorized AP whitelist, after which they can be automatically provisioned with certificates generated by the MC.

質問 # 93
You have an HPE Aruba Networking Mobility Controller (MC) that is locked in a closet. What is another step that HPE Aruba Networking recommends to protect the MC from unauthorized access?

A. Use local authentication rather than external authentication to authenticate admins.
B. Disable local authentication of administrators entirely.
C. Change the password recovery password.
D. Set the local admin password to a long random value that is unknown or locked up securely.

正解：D

解説：
The scenario involves an HPE Aruba Networking Mobility Controller (MC) that is physically secured in a locked closet, which provides protection against physical tampering. However, additional steps are needed to protect the MC from unauthorized access, particularly through administrative interfaces (e.g., SSH, web UI, console).
Option A, "Set the local admin password to a long random value that is unknown or locked up securely," is correct. HPE Aruba Networking recommends securing administrative access to the MC by setting a strong, random password for the local admin account (e.g., the default "admin" user). The password should be long (e.g., 16+ characters), random, and stored securely (e.g., in a password manager or safe). This ensures that even if an attacker gains physical access to the MC (e.g., by bypassing the locked closet) or attempts remote access, they cannot easily guess or brute-force the password.
Option B, "Disable local authentication of administrators entirely," is incorrect. Disabling local authentication entirely would prevent any fallback access to the MC if external authentication (e.g., RADIUS, TACACS+) fails. HPE Aruba Networking recommends maintaining a local admin account as a backup, but securing it with a strong password.
Option C, "Change the password recovery password," is incorrect. AOS-8 Mobility Controllers do not have a specific "password recovery password." Password recovery typically involves physical access to the device (e.g., via the console port) and a factory reset, which would be mitigated by the locked closet. This option is not a standard recommendation for securing the MC.
Option D, "Use local authentication rather than external authentication to authenticate admins," is incorrect. HPE Aruba Networking recommends using external authentication (e.g., RADIUS or TACACS+) for centralized management and stronger security (e.g., two-factor authentication). Local authentication should be a fallback, not the primary method, and it must be secured with a strong password.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"To protect the Mobility Controller from unauthorized access, even if it is physically secured in a locked closet, set the local admin password to a long, random value that is unknown or locked up securely. For example, use a password of at least 16 characters generated by a password manager, and store it in a secure location (e.g., a safe). This ensures that the local admin account, which is used as a fallback, is protected against unauthorized access attempts." (Page 385, Securing Administrative Access Section) Additionally, the HPE Aruba Networking Security Best Practices Guide notes:
"A recommended step to secure the Mobility Controller is to set a strong, random password for the local admin account. The password should be long (e.g., 16+ characters), randomly generated, and stored securely to prevent unauthorized access, even if the device is physically protected in a locked closet."

質問 # 94
You are troubleshooting an authentication issue for HPE Aruba Networking switches that enforce 802.1X to a cluster of HPE Aruba Networking ClearPass Policy Manager (CPPMs). You know that CPPM is receiving and processing the authentication requests because the Aruba switches are showing Access-Rejects in their statistics. However, you cannot find the record for the Access-Rejects in CPPM Access Tracker.
What is something you can do to look for the records?

A. Verify that you are logged in to the CPPM UI with read-write, not read-only, access.
B. Go to the CPPM Event Viewer, because this is where RADIUS Access Rejects are stored.
C. Make sure that CPPM cluster settings are configured to show Access-Rejects.
D. Click Edit in Access Viewer and make sure that the correct servers are selected.

正解：B

解説：
The scenario involves troubleshooting an 802.1X authentication issue on HPE Aruba Networking switches (likely AOS-CX switches) that use a cluster of HPE Aruba Networking ClearPass Policy Manager (CPPM) servers as the RADIUS server. The switches show Access-Rejects in their statistics, indicating that CPPM is receiving and processing the authentication requests but rejecting them. However, the records for these Access-Rejects are not visible in CPPM Access Tracker.
Access Tracker: Access Tracker (Monitoring > Live Monitoring > Access Tracker) in CPPM logs all authentication attempts, including successful (Access-Accept) and failed (Access-Reject) requests. If an Access-Reject is not visible in Access Tracker, it suggests that the request was processed at a lower level and not logged in Access Tracker, or there is a visibility issue (e.g., filtering, clustering).
Option A, "Go to the CPPM Event Viewer, because this is where RADIUS Access Rejects are stored," is correct. The Event Viewer (Monitoring > Event Viewer) in CPPM logs system-level events, including RADIUS-related events that might not appear in Access Tracker. For example, if the Access-Reject is due to a configuration issue (e.g., the switch's IP address is not recognized as a Network Access Device, NAD, or the shared secret is incorrect), the request may be rejected before it is logged in Access Tracker, and the Event Viewer will capture this event (e.g., "RADIUS authentication attempt from unknown NAD"). Since the switches confirm that CPPM is sending Access-Rejects, the Event Viewer is a good place to look for more details.
Option B, "Verify that you are logged in to the CPPM UI with read-write, not read-only, access," is incorrect. Access Tracker visibility is not dependent on read-write vs. read-only access. Both types of accounts can view Access Tracker records, though read-only accounts cannot modify configurations. The issue is that the records are not appearing, not that the user lacks permission to see them.
Option C, "Make sure that CPPM cluster settings are configured to show Access-Rejects," is incorrect. In a CPPM cluster, Access Tracker records are synchronized across nodes, and there is no specific cluster setting to "show Access-Rejects." Access Tracker logs all authentication attempts by default, unless filtered out (e.g., by time range or search criteria), but the issue here is that the records are not appearing at all.
Option D, "Click Edit in Access Viewer and make sure that the correct servers are selected," is incorrect. Access Tracker (not "Access Viewer") does not have an "Edit" option to select servers. In a CPPM cluster, Access Tracker shows records from all nodes by default, and the user can filter by time, NAD, or other criteria, but the absence of records suggests a deeper issue (e.g., the request was rejected before logging in Access Tracker).
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"If an Access-Reject is not visible in Access Tracker, it may indicate that the RADIUS request was rejected at a low level before being logged. The Event Viewer (Monitoring > Event Viewer) logs system-level events, including RADIUS Access-Rejects that do not appear in Access Tracker. For example, if the request is rejected due to an unknown NAD or shared secret mismatch, the Event Viewer will log an event like 'RADIUS authentication attempt from unknown NAD,' providing insight into the rejection." (Page 301, Troubleshooting RADIUS Issues Section) Additionally, the HPE Aruba Networking AOS-CX 10.12 Security Guide notes:
"When troubleshooting 802.1X authentication issues, if the switch logs show Access-Rejects from the RADIUS server (e.g., ClearPass) but the records are not visible in Access Tracker, check the RADIUS server's system logs. In ClearPass, the Event Viewer logs RADIUS Access-Rejects that may not appear in Access Tracker, such as those caused by NAD configuration issues."

質問 # 95
What is a Key feature of me ArubaOS firewall?

A. The firewall is designed to fitter traffic primarily based on wireless 802.11 headers, making it ideal for mobility environments
B. The firewall examines all traffic at Layer 2 through Layer 4 and uses source IP addresses as the primary way to determine how to control traffic.
C. The firewall is stateful which means that n can track client sessions and automatically allow return traffic for permitted sessions
D. The firewall Includes application layer gateways (ALGs). which it uses to filter Web traffic based on the reputation of the destination web site.

正解：C

解説：
The ArubaOS firewall is a stateful firewall, meaning that it can track the state of active sessions and can make decisions based on the context of the traffic. This stateful inspection capability allows it to automatically allow return traffic for sessions that it has permitted, thereby enabling seamless two-way communication for authorized users while maintaining the security posture of the network.References:
ArubaOS firewall documentation.

質問 # 96
You have been asked to send RADIUS debug messages from an ArubaOS-CX switch to a central SIEM server at 10.5.15.6. The server is already defined on the switch with this command: logging 10.5.6.12 You enter this command: debug radius all What is the correct debug destination?

A. buffer
B. file
C. console
D. syslog

正解：D

解説：
When configuring an ArubaOS-CX switch to send RADIUS debug messages to a central SIEM server, it is important to correctly direct these debug outputs. The command debug radius all activates debugging for all RADIUS processes, capturing detailed logs about RADIUS operations. If the SIEM server is already defined on the switch for logging purposes (as indicated by the command logging 10.5.6.12), the correct destination for these debug messages to be sent to the SIEM server would be through the syslog. This ensures that all generated logs are forwarded to the centralized server specified for logging, enabling consistent log management and analysis. Using syslog as the destination leverages the existing logging setup and integrates seamlessly with the network's centralized monitoring systems.
