NEW QUESTION # 139
A company wants you to integrate HPE Aruba Networking ClearPass Policy Manager (CPPM) with HPE Aruba Networking ClearPass Device Insight (CPDI).
What is one aspect of the integration that you should explain?
Answer: B
Explanation:
When integrating ClearPass Policy Manager (CPPM) with ClearPass Device Insight (CPDI), it is important to understand how device profiling and classification work between the two solutions:
1. CPPM and CPDI Integration Overview
* CPPM is primarily used for access control and policy enforcement, while CPDI specializes in device profiling and classification through advanced analytics and machine learning.
* Integration allows CPPM to leverage CPDI's enhanced profiling capabilities for more accurate device identification and policy enforcement.
2. Detailed Analysis of Each Option
A: CPPM no longer supports any Device Profiler features and relies on CPDI for this profile information:
* Incorrect: CPPM still supports its own basic device profiling features and can operate independently.
However, when integrated with CPDI, CPPM can use CPDI's advanced profiling capabilities as a supplement.
B: CPDI must be configured as an audit server on CPPM for the integration to be successful:
* Incorrect: CPDI is not configured as an audit server on CPPM. Integration is achieved via API integration and communication between the two solutions, not through audit server settings.
C: CPDI must have security analysis disabled on it for the integration to be successful:
* Incorrect: Security analysis does not need to be disabled for integration. In fact, CPDI's security analysis enhances the classification process by identifying anomalous behaviors.
D: CPPM can submit profile information to CPDI, but if CPDI derives a different classification, CPDI takes precedence:
* Correct:
* CPPM and CPDI exchange profile data, but CPDI has more advanced device classification capabilities due to its machine learning-based engine.
* When CPDI derives a different classification than CPPM, CPDI's classification is considered more accurate and takes precedence.
* This ensures that policies are based on the most reliable device classification.

NEW QUESTION # 140 
The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?
Answer: A
Explanation:
To follow best security practices for 802.1X authentication settings in Windows domain clients:
Specify at least two server names under " Connect to these servers " :
Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
Select the desired Trusted Root Certificate Authority and " Don ' t prompt users " :
Select the Trusted Root CA that issued the RADIUS server ' s certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
Enabling " Don ' t prompt users " ensures end users are not confused or tricked into accepting certificates from untrusted servers.
Why the other options are incorrect:
Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
Option D: Incorrect. Clearing " Use simple certificate selection " requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
Server Validation: Specify the exact RADIUS server names in the " Connect to these servers " field.
Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
User Prompts: Enable " Don ' t prompt users " to enforce automatic and secure authentication without user intervention.
NEW QUESTION # 141
A company has AOS-CX switches. The company wants to make it simpler and faster for admins to detect denial of service (DoS) attacks, such as ping or ARP floods, launched against the switches.
What can you do to support this use case?
Answer: A
Explanation:
Why Monitoring Control Plane Policing (CoPP) with an NAE Agent Is Effective for Detecting DoS Attacks
* Control Plane Policing (CoPP): AOS-CX switches use CoPP to protect the CPU from excessive traffic caused by DoS attacks (e.g., ARP floods, ICMP floods). CoPP enforces rate limits and drops malicious traffic at the control plane level.
* NAE (Network Analytics Engine) Agent:
* The NAE on AOS-CX switches can monitor CoPP counters in real time and trigger alerts if thresholds for certain traffic types (e.g., ICMP, ARP) are exceeded.
* Admins can use NAE to automate detection and respond faster to DoS attacks.
Analysis of Each Option
A: Deploy an NAE agent on the switches to monitor control plane policing (CoPP):
* Correct:
* NAE agents provide real-time visibility into CoPP behavior, helping detect DoS attacks more quickly.
* By analyzing CoPP statistics, the NAE can pinpoint abnormal traffic patterns and alert admins.
* This is the most efficient and scalable solution for this use case.
B: Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight:
* Incorrect:
* While ClearPass can provide visibility into user authentication and device activity, it is not specifically designed to detect or mitigate DoS attacks against switches.
C: Implement ARP inspection on all VLANs that support end-user devices:
* Incorrect:
* ARP inspection helps mitigate ARP spoofing or poisoning, but it does not directly address detection of DoS attacks like ICMP or ARP floods.
* It is a preventative measure, not a detection tool.
D: Enabling debugging of security functions on the switches:
* Incorrect:
* Debugging logs can help troubleshoot specific issues but are not practical for real-time detection of DoS attacks.
* Enabling debugging can overload the switch and is not suitable for proactive monitoring.
Final Recommendation
Deploying an NAE agent to monitor CoPP is the best solution because it provides real-time detection, alerting, and insights into traffic patterns that indicate DoS attacks.

NEW QUESTION # 142
You have run an Active Endpoint Security Report on HPE Aruba Networking ClearPass. The report indicates that hundreds of endpoints have MAC addresses but no known IP addresses.
What is one step for addressing this issue?
Answer: C
Explanation:
When the Active Endpoint Security Report on HPE Aruba Networking ClearPass indicates that endpoints have MAC addresses but no known IP addresses, one effective step to address this issue is to add CPPM's (ClearPass Policy Manager) IP address to the IP helper list on routing switches. This configuration ensures that DHCP requests are forwarded to the ClearPass server, allowing it to track and report the IP addresses assigned to the endpoints. This helps ClearPass maintain an accurate mapping of MAC addresses to IP addresses, improving endpoint visibility and security management.
NEW QUESTION # 143
Which statement describes Zero Trust Security?
Answer: C
Explanation:
What is Zero Trust Security?
Zero Trust Security is a security model that operates on the principle of " never trust, always verify. " It focuses on securing resources (data, applications, systems) and continuously verifying the identity and trust level of users and devices, regardless of whether they are inside or outside the network.
The primary aim is to reduce reliance on perimeter defenses and implement granular access controls to protect individual resources.
Analysis of Each Option
A). Companies must apply the same access controls to all users, regardless of identity:
Incorrect:
Zero Trust enforces dynamic and identity-based access controls, not the same static controls for everyone.
Users and devices are granted access based on their specific context, role, and trust level.
B). Companies that support remote workers cannot achieve zero trust security and must determine if the benefits outweigh the cost:
Incorrect:
Zero Trust is particularly effective for securing remote work environments by verifying and authenticating remote users and devices before granting access to resources.
The model is adaptable to hybrid and remote work scenarios, making this statement false.
C). Companies should focus on protecting their resources rather than on protecting the boundaries of their internal network:
Correct:
Zero Trust shifts the focus from perimeter security (traditional network boundaries) to protecting specific resources.
This includes implementing measures such as:
Micro-segmentation.
Continuous monitoring of user and device trust levels.
Dynamic access control policies.
The emphasis is on securing sensitive assets rather than assuming an internal network is inherently safe.
D). Companies can achieve zero trust security by strengthening their perimeter security to detect a wider range of threats:
Incorrect:
Zero Trust challenges the traditional reliance on perimeter defenses (firewalls, VPNs) as the sole security mechanism.
Strengthening perimeter security is not sufficient for Zero Trust, as this model assumes threats can already exist inside the network.
Final Explanation
Zero Trust Security emphasizes protecting resources at the granular level rather than relying on the traditional security perimeter, which makes C the most accurate description.
