HP Aruba Certified Network Security Professional Exam Sample Questions (Q125-Q130):

NEW QUESTION # 125
Refer to the Exhibit:

These packets have been captured from VLAN 10. which supports clients that receive their IP addresses with DHCP.
What can you interpret from the packets that you see here?
These packets have been captured from VLAN 10, which supports clients that receive their IP addresses with DHCP. What can you interpret from the packets that you see here?

A. An admin has likely misconfigured two clients to use the same DHCP settings.
B. The mirroring session that captured the packets was likely misconfigured and captured duplicate traffic.
C. Someone is possibly implementing an ARP poisoning and MITM attack.
D. Someone is possibly implementing a MAC spoofing attack to gain unauthorized access.

Answer: D

Explanation:
The exhibit reveals duplicate IP addresses detected for 10.1.140.6, associated with two different MAC addresses:
* 88:56:56:ab:c6:89
* 88:13:30:a3:02:00
Key observations:
* Duplicate IP Address Detection:
* The message "Duplicate IP address detected for 10.1.140.6" clearly indicates two devices claiming the same IP address.
* This typically occurs when one device spoofs the MAC address of another device to intercept or disrupt traffic.
* MAC Spoofing Context:
* MAC spoofing is a tactic used to impersonate another device's hardware address to gain unauthorized access to a network.
* By spoofing a legitimate IP-MAC pairing, an attacker can bypass security mechanisms or cause denial-of-service conditions.
* Why the Other Options are Incorrect:
* Option B (Mirroring Misconfigured): While mirroring misconfiguration can duplicate traffic, it does not lead to a "duplicate IP detected" alert.
* Option C (Misconfigured DHCP): Misconfigurations usually result in DHCP conflicts, but they do not typically involve two different MAC addresses for the same IP.
* Option D (ARP Poisoning/MITM): ARP poisoning involves falsified ARP tables, but it does not directly trigger duplicate IP address detection. Instead, ARP packets flood the network.
Conclusion:
The evidence strongly suggests MAC spoofing, as two different MAC addresses are claiming the same IP address (10.1.140.6). This behavior is typical of attempts to gain unauthorized access or disrupt network operations.

NEW QUESTION # 126
Which issue can an HPE Aruba Networking Secure Web Gateway (SWG) solution help customers address?

A. Remote workers need access to private data center applications without exposing those applications to unauthorized users.
B. The organization needs a faster way to quarantine clients that have generated threats, as detected by third-party firewalls.
C. The organization currently has no way to prevent users from exfiltrating sensitive data from SaaS applications.
D. Hybrid workers are exposing their computers to risky internet sites and infection by malware when they work from home.

Answer: D

Explanation:
An HPE Aruba Networking Secure Web Gateway (SWG) is designed to provide secure internet access by monitoring and controlling web traffic. It primarily focuses on protecting users from malicious content and ensuring compliance with corporate security policies, particularly for hybrid and remote workers.
Explanation of Each Option
A: The organization needs a faster way to quarantine clients that have generated threats, as detected by third-party firewalls.
* Incorrect:
* Quarantining clients based on detected threats is typically managed by endpoint detection and response (EDR) solutions or next-generation firewalls (NGFWs).
* While an SWG can monitor and block risky web activity, it does not manage threat quarantine actions directly.
B: Hybrid workers are exposing their computers to risky internet sites and infection by malware when they work from home.
* Correct:
* SWGs monitor and control web traffic to block malicious websites and prevent exposure to malware.
* They enforce web usage policies even when users work remotely, protecting against phishing, drive-by downloads, and other web-based threats.
* With the proliferation of hybrid work environments, an SWG ensures that users are protected from risky sites regardless of their location.
C: Remote workers need access to private data center applications without exposing those applications to unauthorized users.
* Incorrect:
* This use case falls under secure access service edge (SASE) solutions with Zero Trust Network Access (ZTNA), not an SWG.
* ZTNA focuses on granting secure, conditional access to applications, while SWGs focus on internet traffic security.
D: The organization currently has no way to prevent users from exfiltrating sensitive data from SaaS applications.
* Incorrect:
* Data loss prevention (DLP) tools or cloud access security brokers (CASBs) are designed for monitoring and preventing data exfiltration from SaaS applications.
* While SWGs can block access to specific websites or categories, they do not offer advanced DLP capabilities for SaaS environments.

NEW QUESTION # 127
Admins have recently turned on Wireless IDS/IPS infrastructure detection at the high level on HPE Aruba Networking APs. When you check WIDS events, you see several RTS rate and CTS rate anomalies, which were triggered by neighboring APs.
What can you interpret from this event?

A. These neighboring APs are actually rogue APs, and you should enable wireless tarpit containment on them.
B. These neighboring APs are actually rogue APs, and you should enable wireless de-authentication containment on them.
C. These neighboring APs are likely to be wireless clients that are inappropriately bridging their wired and wireless NICs; you should track down and remove them.
D. These neighboring APs might be hackers trying to launch a DoS, but are more likely operating normally; you should start by tuning the event thresholds.

Answer: D

Explanation:
When Wireless IDS/IPS infrastructure detection reports RTS (Request to Send) and CTS (Clear to Send) rate anomalies triggered by neighboring APs, it is often an indication of unusual, but not necessarily malicious, behavior. These anomalies can be caused by neighboring APs operating normally but under specific conditions that trigger the alerts. Before assuming a security threat, it is recommended to tune the event thresholds to better match the environment and reduce false positives. This approach helps to distinguish between normal operations and potential DoS attacks.
Reference: Aruba's Wireless IDS/IPS configuration guides provide information on interpreting events, adjusting thresholds, and distinguishing between legitimate and malicious activities in a wireless network environment.

NEW QUESTION # 128
You have created this rule in an HPE Aruba Networking ClearPass Policy Manager (CPPM) service's enforcement policy: IF Authorization [Endpoints Repository] Conflict EQUALS true THEN apply "quarantine_profile" What information can help you determine whether you need to configure cluster-wide profiler parameters to ignore some conflicts?

A. Whether the company has rare Internet of Things (loT) devices
B. Whether the company has devices that use PXE boot
C. Whether some devices are incapable of captive portal or 802.1X authentication
D. Whether some devices are running legacy operating systems

Answer: B

Explanation:
When you have created a rule in a ClearPass Policy Manager (CPPM) service's enforcement policy to quarantine devices with endpoint conflicts, it is important to consider whether the company has devices that use PXE boot. PXE booting devices can create conflicts in the profiler because they may temporarily have different network attributes (e.g., MAC address or IP address) before fully booting and obtaining their final configuration. Understanding whether PXE boot is in use can help determine if profiler parameters need to be adjusted to ignore such temporary conflicts, ensuring that devices are not incorrectly quarantined.

NEW QUESTION # 129
Refer to Exhibit.

A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application). In the CPDI interface, you go to the Generic Devices page and see the view shown in the exhibit.
What correctly describes what you see?

A. Each cluster is a group of devices that match one of the tags configured by admins.
B. Each cluster is a group of devices that have been classified with user rules, but for which CPDI offers different recommendations.
C. Each cluster is a group of unclassified devices that CPDI's machine learning has discovered to have similar attributes.
D. Each cluster is all the devices that have been assigned to the same category by one of CPDI's built-in system rules.

Answer: C

Explanation:
In HPE Aruba Networking ClearPass Device Insight (CPDI), the clusters shown in the exhibit represent groups of unclassified devices that CPDI's machine learning algorithms have identified as having similar attributes. These clusters are formed based on observed characteristics and behaviors of the devices, helping administrators to categorize and manage devices more effectively.
1.Machine Learning: CPDI uses machine learning to analyze device attributes and group them into clusters based on similarities.
2.Unclassified Devices: These clusters typically represent devices that have not yet been explicitly classified by admins but share common attributes that suggest they belong to the same category.
3.Management: This clustering helps in simplifying the process of managing and applying policies to groups of similar devices.
Reference: ClearPass Device Insight documentation on device clustering and machine learning provides detailed information on how devices are grouped into clusters based on observed attributes and behaviors.
