NEW QUESTION # 67
A port-access role for AOS-CX switches has this policy applied to it:
plaintext
Copy code
port-access policy mypolicy
10 class ip zoneC action drop
20 class ip zoneA action drop
100 class ip zoneB
The classes have this configuration:
plaintext
Copy code
class ip zoneC
10 match tcp 10.2.0.0/16 eq https
class ip zoneA
10 match ip any 10.1.0.0/16
class ip zoneB
10 match ip any 10.0.0.0/8
The company wants to permit clients in this role to access 10.2.12.0/24 with HTTPS. What should you do?

  • A. Add this rule to zoneC: 5 match any 10.2.12.0/24 eq https
  • B. Add this rule to zoneB: 5 match tcp any 10.2.12.0/24 eq https
  • C. Add this rule to zoneC: 5 ignore tcp any 10.2.12.0/24 eq https
  • D. Add this rule to zoneA: 5 ignore tcp any 10.2.12.0/24 eq https

Answer: A

Explanation:
Comprehensive Detailed Explanation
* The requirement is to permit HTTPS traffic from clients to the 10.2.12.0/24 subnet.
* ZoneC is configured to drop all HTTPS traffic to the 10.2.0.0/16 subnet. Therefore, the first match in the zoneC class (priority 10) will drop the desired traffic.
* To override this behavior, you must add a higher-priority rule (lower rule number) to zoneC that explicitly matches 10.2.12.0/24 and permits the traffic.
Thus, adding the rule 5 match any 10.2.12.0/24 eq https to zoneC ensures the desired traffic is permitted while maintaining the drop behavior for the rest of 10.2.0.0/16.

NEW QUESTION # 68
A company has been running Gateway IDS/IPS on its gateways in IDS mode for several weeks. The company wants to transition to IPS mode.
What is one step you should recommend?

  • A. Consider applying a stricter IPS policy to minimize issues during the transition period.
  • B. Change the mode on one gateway at a time to establish a smoother transition period.
  • C. Check for legitimate traffic that has been flagged as a threat and allow list the associated rules.
  • D. Disable traffic inspection and reboot before re-enabling traffic inspection with the new mode.

Answer: C

Explanation:
When transitioning from Intrusion Detection System (IDS) mode to Intrusion Prevention System (IPS) mode, it's critical to review and refine configurations to ensure legitimate traffic is not blocked. Here's the reasoning behind each option:
A: Disable traffic inspection and reboot before re-enabling traffic inspection with the new mode.
* Incorrect:
* Transitioning to IPS mode does not require a full reboot or disabling traffic inspection.
* This step is unnecessary and could lead to downtime that impacts network operations.
B: Change the mode on one gateway at a time to establish a smoother transition period.
* Incorrect:
* While a phased approach might help in some large deployments, it does not directly address the potential for legitimate traffic to be blocked by IPS mode.
* IPS operates in real-time, so misconfigured rules or policies need to be addressed before enabling IPS on any gateway.
C: Consider applying a stricter IPS policy to minimize issues during the transition period.
* Incorrect:
* A stricter IPS policy increases the likelihood of false positives, which could disrupt legitimate business-critical traffic.
* During the transition, the focus should be on minimizing disruptions by fine-tuning policies, not making them stricter.
D: Check for legitimate traffic that has been flagged as a threat and allow list the associated rules.
* Correct:
* In IDS mode, the system only detects and logs suspicious traffic but does not block it. Reviewing these logs for false positives allows the organization to fine-tune policies and allow list legitimate traffic before transitioning to IPS mode.
* By doing this, the company ensures that IPS mode will block actual threats while permitting legitimate traffic.
* This is a proactive step to prevent unnecessary disruptions to normal operations when IPS mode is enabled.

NEW QUESTION # 69
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?

  • A. Enabling debugging of security functions on the switches.
  • B. Deploy an NAE agent on the switches to monitor control plane policing (CoPP).
  • C. Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight.
  • D. Implement ARP inspection on all VLANs that support end-user devices.

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.
