NEW QUESTION # 126
How can HPE Aruba Networking User-Based Tunneling (UBT) help companies implement a Zero Trust Security strategy?
Answer: C
Explanation:
User-Based Tunneling supports Zero Trust by allowing organizations to enforce consistent role-based policies for wired and wireless users. Instead of trusting a device because it is physically connected to the LAN, the network uses identity, role, and context to determine access. UBT can tunnel selected wired traffic from AOS- CX switches to gateways where centralized firewall policies are applied. This allows wired users to receive enforcement similar to wireless users. Zero Trust requires least-privilege access and consistent policy based on identity and device context, not broad network placement. UBT is not mainly about VXLAN, universal LAN encryption, or cloud-zone extension. Its main Zero Trust value is consistent identity-based access enforcement.
NEW QUESTION # 127
A company has HPE Aruba Networking Central-managed APs. The company wants to block all clients connected through the APs from using YouTube.
Which steps should you take?
Answer: D
Explanation:
To block all clients connected through HPE Aruba Networking Central-managed APs from accessing YouTube, you should enable DPI (Deep Packet Inspection) and then create application rules to deny YouTube on the firewall roles. DPI allows the network to inspect and classify traffic based on application signatures, making it possible to enforce application-specific policies. By creating rules that specifically block YouTube traffic, you can effectively prevent clients from accessing the service.
NEW QUESTION # 128
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: B
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 # 129
As part of setting up an HPE Aruba Networking ClearPass Onboard solution for wireless clients, you created Network Settings, a Configuration Profile, and a Provisioning Settings object in ClearPass Onboard. You also ran the ClearPass Onboard Service Only Template on ClearPass Policy Manager (CPPM).
You now need to ensure that only domain users are authenticated and allowed to log into the ClearPass Onboard portal.
Which component should you edit?
Answer: A
Explanation:
Access to the Onboard portal is controlled by a dedicated Pre-Auth service in ClearPass Policy Manager:
* The "ClearPass Onboard Service Pre-Auth" service defines which authentication sources (e.g., AD domain, local DB, guest) are used when users log into the Onboard web portal.
* To restrict access to domain users only, you edit this Pre-Auth service to use only the Active Directory auth source (and appropriate authorization checks, such as group membership).
Exam and configuration references for ClearPass Onboard clearly identify the Onboard Pre-Auth service as the place where you control who can log into the Onboard portal.
* Network Settings and Provisioning profiles in Onboard govern SSID, profiles, and device configuration, not portal user authentication.
* The 802.1X services for wireless control network access after onboarding, not login to the onboarding portal itself.
Therefore, to limit the portal to domain users, you should edit the ClearPass Onboard Service Pre-Auth service on CPPM # Option B.
NEW QUESTION # 130
A company wants to use the HPE Aruba Networking ClearPass OnGuard agent to assign posture to clients.
How do you define the conditions by which a client receives a particular posture?
Answer: C
Explanation:
ClearPass OnGuard uses a Posture Policy object to define:
Which checks are performed (e.g., AV installed, firewall status, patches) How the results map to posture tokens such as "Healthy," "Quarantined," etc.
The official OnGuard configuration workflow states that you must first "Define the posture policy", and that these posture policies contain the rules for evaluating health and determining posture tokens.
Service enforcement policies then consume the posture token (e.g., Tips:Posture = Healthy) but do not define the posture conditions themselves. The "Posture" tab on a service is used to enable posture and associate it with the posture policy; the detailed rules live in the posture policy object.
Therefore, posture logic is defined by creating rules within a posture policy # Option A.
