質問 # 68
A company has AOS-CX switches at the access layer, managed by HPE Aruba Networking Central. You have identified suspicious activity on a wired client. You want to analyze the client's traffic with Wireshark, which you have on your management station.
What should you do?
正解：C
解説：
Why a Mirror Session Is the Correct Choice
To analyze a wired client's traffic with Wireshark, you need the traffic mirrored to your management station where Wireshark is installed. The most effective way to achieve this is by configuring a mirror session on the AOS-CX switch, specifying the client port as the source and your management station as the destination.
Analysis of Each Option
A: Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port:
* Incorrect:
* AOS-CX switches do not natively support packet capture (e.g., tcpdump) directly on the switch CLI.
* This approach is not feasible for capturing and analyzing live client traffic.
B: Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture:
* Incorrect:
* HPE Aruba Networking Central provides security insights but does not directly support initiating packet captures for detailed analysis.
* Traffic analysis with tools like Wireshark requires local packet capture at the management station.
C: Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port:
* Incorrect:
* Captive portals are designed for user authentication and redirection, not traffic analysis.
* This would disrupt the client's network activity without enabling traffic analysis in Wireshark.
D: Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination:
* Correct:
* Mirroring the client port to your management station is the standard method for analyzing live network traffic with Wireshark.
* Steps include:
* Configure a mirror session on the client's AOS-CX switch.
* Set the client's port as the source.
* Set your management station as the destination using its IP address (via GRE tunnel or physical interface).
* Start capturing traffic with Wireshark on the management station.
Final Recommendation
To analyze the client's traffic, configure a mirror session on the switch, set the client port as the source, and direct the traffic to your management station where Wireshark is running.

Refer to Exhibit:
An HPE Aruba Networking 9x00 gateway is part of an HPE Aruba Networking Central group that has the settings shown in the exhibit. What would cause the gateway to drop traffic as part of its IDPS settings?
正解：A
解説：
1. IDPS Mode Configuration Overview
The exhibit shows the HPE Aruba Networking Central settings for the Gateway IDS/IPS configuration:
Mode: Configured for Intrusion Prevention System (IPS), meaning that the gateway actively blocks traffic identified as threats.
Fail Strategy: Configured to Block, meaning that if the gateway cannot determine the traffic ' s nature due to a system issue, it will block the traffic.
Ruleset: The gateway uses a predefined set of intrusion detection/prevention rules (ruleset version 9861), which is updated automatically every day.
2. Traffic Evaluation in IPS Mode
In IPS mode, the gateway analyzes traffic against the active ruleset:
If traffic matches a rule in the ruleset and is deemed malicious, the gateway will drop the traffic as part of its prevention mechanism.
The ruleset defines specific conditions (e.g., signatures of known attacks, protocol anomalies) under which traffic should be blocked.
3. Explanation of Each Option
A). Its site-to-site VPN connections failing:
Incorrect:
Site-to-site VPN connection issues do not directly trigger traffic drops under IDPS settings.
IDPS is focused on detecting and preventing malicious activity, not general connectivity issues.
B). Traffic matching a rule in the active ruleset:
Correct:
In IPS mode, the gateway drops traffic that matches any predefined rules in the active ruleset.
For example, if traffic matches the signature of a known exploit or attack, it is immediately blocked.
C). Its IDPS engine failing:
Incorrect:
The fail strategy determines how the gateway behaves in the event of an IDPS engine failure.
In this case, the fail strategy is set to Block, but this applies only if the engine itself fails, not as a proactive traffic drop mechanism.
D). Traffic showing anomalous behavior:
Incorrect:
While anomalous behavior may be logged or flagged, it does not necessarily lead to traffic drops unless it matches a specific rule in the active ruleset.
Anomaly detection alone is not sufficient for IPS action without explicit rule matches.
Final Outcome:
Traffic is dropped only when it matches a rule in the active ruleset, ensuring targeted prevention of malicious activity.

質問 # 70
You are establishing a cluster of HPE Aruba Networking ClearPass servers. (Assume that they are running version 6.9.).
For which type of certificate it is recommended to install a CA-signed certificate on the Subscriber before it joins the cluster?
正解：D
解説：
When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA-signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in the cluster and provides a trusted certificate for client connections.
1.HTTPS Security: A CA-signed certificate for HTTPS ensures that all web-based communication to and from the ClearPass server is encrypted and secure.
2.Cluster Communication: Secure communication between ClearPass nodes in the cluster is essential for synchronization and data integrity.
3.Client Trust: Clients accessing the ClearPass server will trust the CA-signed certificate, avoiding security warnings and ensuring smooth operations.
質問 # 71
A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application).
You have identified a device, which is currently
classified as one type, but you want to classify it as a custom type. You also want to classify all devices with similar attributes as this type, both already-discovered devices and new devices discovered later.
What should you do?
正解：D
解説：
When using HPE Aruba Networking ClearPass Device Insight (CPDI) and you need to reclassify a device to a custom type and apply this classification to all devices with similar attributes, both already discovered and newly discovered, you should follow these steps:
1.Navigate to the device details in CPDI.
2.Select the option to reclassify the device.
3.Create a user rule based on the desired attributes of the device.
4.Choose the "Save & Reclassify" option.
This process ensures that the device is reclassified according to the new custom type and that the rule is applied to all existing and future devices with matching attributes, maintaining consistent classification across the network.
質問 # 72
An AOS-CX switch has been configured to implement UBT to a cluster of three HPE Aruba Networking gateways.
How does the switch determine to which gateways to tunnel UBT users' traffic?
正解：D
解説：
When an AOS-CX switch implements User-Based Tunneling (UBT) to a cluster of three HPE Aruba Networking gateways, the switch determines to which gateway to tunnel each user's traffic based on the particular gateway assigned as that user's active user designated gateway. This ensures that traffic is efficiently distributed and managed according to the designated gateway for each user.
1.User Designated Gateway: Each user's traffic is tunneled to a specific gateway that has been designated for that user, ensuring efficient handling of traffic.
2.Traffic Distribution: This method allows for balanced distribution of user traffic across multiple gateways, enhancing network performance and reliability.
3.Gateway Assignment: The switch uses the assigned gateway for each user to determine the tunneling path, ensuring that traffic is directed to the appropriate gateway.
Reference: Aruba's UBT and AOS-CX configuration guides detail the process of setting up and managing user-based tunneling, including the assignment of user designated gateways for traffic tunneling.
