HP Aruba Certified Network Security Associate Exam Sample Questions (Q74-Q79):

NEW QUESTION # 74
You are managing an Aruba Mobility Controller (MC). What is a reason for adding a "Log Settings" definition in the ArubaOS Diagnostics > System > Log Settings page?

A. Configuring a filter that you can apply to a defined Syslog server in order to filter events by subcategory
B. Configuring the MC to generate logs for a particular event category and level, but only for a specific user or AP.
C. Configuring the log facility and log format that the MC will use for forwarding logs to all Syslog servers
D. Configuring the Syslog server settings for the server to which the MC forwards logs for a particular category and level

Answer: D

NEW QUESTION # 75
What is a use case for Transport Layer Security (TLS)?

A. to enable a client and a server to establish secure communications for another protocol
B. to enable two parties to asymmetrically encrypt and authenticate all data that passes be-tween them
C. to provide a secure alternative to certificate authentication that is easier to implement
D. to establish a framework for devices to determine when to trust other devices' certificates

Answer: A

Explanation:
The use case for Transport Layer Security (TLS) is to enable a client and a server to establish secure communications for another protocol. TLS is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used for web browsers and other applications that require data to be securely exchanged over a network, such as file transfers, VPN connections, and voice-over-IP (VoIP). TLS operates between the transport layer and the application layer of the Internet Protocol Suite and is used to secure various other protocols like HTTP (resulting in HTTPS), SMTP, IMAP, and more. This protocol ensures privacy and data integrity between two communicating applications. Detailed information about TLS and its use cases can be found in IETF RFC 5246, which outlines the specifications for TLS 1.2, and in subsequent RFCs that define TLS 1.3.

NEW QUESTION # 76
What is one way that Control Plane Security (CPsec) enhances security for me network?

A. It prevents Denial of Service (DoS) attacks against Mobility Controllers' (MCs") control plane.
B. It protects management traffic between APs and Mobility Controllers (MCs) from eavesdropping.
C. It protects wireless clients' traffic tunneled between APs and Mobility Controllers, from eavesdropping
D. It prevents access from unauthorized IP addresses to critical services, such as SSH on Mobility Controllers (MCs).

Answer: B

Explanation:
Control Plane Security (CPsec) enhances security in the network by protecting management traffic between APs and Mobility Controllers (MCs) from eavesdropping. CPsec ensures that all control and management traffic that transits the network is encrypted, thus preventing potential attackers from gaining access to sensitive management data. It helps in securing the network's control plane, which is crucial for maintaining the integrity and privacy of the network operations.References:
Aruba Networks' CPsec documentation.

NEW QUESTION # 77
Which is a correct description of a stage in the Lockheed Martin kill chain?

A. In the weaponization stage, which occurs after malware has been delivered to a system, the malware executes Its function.
B. In the reconnaissance stage, the hacker assesses the impact of the attack and how much information was exfilltrated.
C. In the delivery stage, malware collects valuable data and delivers or exfilltrated it to the hacker.
D. In the exploitation and installation phases, malware creates a backdoor into the infected system for the hacker.

Answer: D

Explanation:
The Lockheed Martin Cyber Kill Chain model describes the stages of a cyber attack. In the exploitation phase, the attacker uses vulnerabilities to gain access to the system. Following this, in the installation phase, the attacker installs a backdoor or other malicious software to ensure persistent access to the compromised system. This backdoor can then be used to control the system, steal data, or execute additional attacks.

NEW QUESTION # 78
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. Click Edit in Access Viewer and make sure that the correct servers are selected.
C. Make sure that CPPM cluster settings are configured to show Access-Rejects.
D. Go to the CPPM Event Viewer, because this is where RADIUS Access Rejects are stored.

Answer: D

Explanation:
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."
