NEW QUESTION # 14
A company has wired VolP phones, which transmit tagged traffic and connect to AOS-CX switches. The company wants to tunnel the phones' traffic to an HPE Aruba Networking gateway for applying security policies.
What is part of the correct configuration on the AOS-CX switches?
- A. UBT mode set to VLAN extend
- B. VLANs assigned to the VolP phones configured on the switch uplinks
- C. A UBT reserved VLAN set to a VLAN dedicated for that purpose
- D. A VXLAN VNI mapped to the VLAN assigned to the VolP phones
Answer: C
Explanation:
To tunnel VoIP phone traffic from AOS-CX switches to an HPE Aruba Networking gateway, you need to configure a User-Based Tunneling (UBT) reserved VLAN on the switches. This VLAN is dedicated for tunneling purposes and ensures that the VoIP traffic is correctly identified and tunneled to the gateway where security policies can be applied.
1.UBT Configuration: Setting a UBT reserved VLAN ensures that the switch knows which VLAN to use for tunneling traffic to the gateway.
2.Traffic Tunneling: The reserved VLAN helps in segregating the VoIP traffic, ensuring it is handled securely and according to the configured policies at the gateway.
3.Policy Application: By tunneling the traffic, the gateway can apply advanced security policies to the VoIP traffic.
Reference: Aruba's AOS-CX and UBT configuration guides detail the steps for setting up reserved VLANs for tunneling traffic to gateways.
NEW QUESTION # 15
What is one use case for implementing user-based tunneling (UBT) on AOS-CX switches?
- A. Tunneling traffic directly to a third-party firewall in a client data center
- B. Applying enhanced security features such as deep packet inspection (DPI) to wired traffic
- C. Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
- D. Centralizing the distribution of wired traffic without requiring HPE Aruba Networking gateways
Answer: B
Explanation:
Implementing user-based tunneling (UBT) on AOS-CX switches is beneficial for applying enhanced security features such as deep packet inspection (DPI) to wired traffic. UBT allows the traffic from specific users or devices to be tunneled to a central controller or security appliance where advanced security policies, including DPI, can be applied. This approach ensures that even wired traffic benefits from the same level of security and inspection typically available for wireless traffic, thus enhancing overall network security.
Reference: Aruba's documentation on UBT and AOS-CX configuration guides detail how to set up user-based tunneling and the benefits of applying advanced security features like DPI to tunneled traffic.
NEW QUESTION # 16
A company has AOS-CX switches and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants switches to implement 802.1X authentication to CPPM and download user roles. What is one task that you must complete on CPPM to support this use case?
- A. Create an admin account for the switch on CPPM with the HPE Aruba Networking User Role Download privilege level.
- B. Upload the switch TPM certificate as a trusted CA certificate with the Others usage.
- C. Configure RADIUS enforcement profiles that specify the HPE-User-Role VSA.
- D. Export roles on CPPM to a file that uses XML format.
Answer: C
Explanation:
* 802.1X and User Role Download:
* AOS-CX switches use RADIUS attributes to dynamically download user roles from CPPM.
* The HPE-User-Role VSA (Vendor-Specific Attribute) must be configured in the RADIUS enforcement profiles to specify which role the switch should apply.
* Option Analysis:
* Option A: Incorrect. Exporting roles in XML is not needed for dynamic role download.
* Option B: Incorrect. Switches authenticate via RADIUS, not admin accounts with specific privileges.
* Option C: Correct. RADIUS enforcement profiles must include the HPE-User-Role VSA to implement user role download.
* Option D: Incorrect. TPM certificates are unrelated to RADIUS-based user role downloads.
NEW QUESTION # 17
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?
- A. Enable DPI. Then, create application rules to deny YouTube on the firewall roles.
- B. Enable WebCC on all client firewall roles. Then, create WebCC category rules that deny suspicious URLs.
- C. Deploy gateways and have the APs tunnel traffic to the gateways. Then, enable the gateway IDS/IPS engine.
- D. Enable Client IPS at the "custom" level, and then specify the check for YouTube.
Answer: A
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.
Reference: Aruba Central's documentation on firewall and application control provides detailed instructions on enabling DPI and creating application rules to manage and restrict access to specific applications such as YouTube.

NEW QUESTION # 20
A company has several use cases for using its AOS-CX switches' HPE Aruba Networking Network Analytics Engine (NAE).
What is one guideline to keep in mind as you plan?
- A. When you use custom scripts, you can create as many agents from each script as you want.
- B. Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
- C. You can install multiple scripts on a switch, but you can deploy only one agent per script.
- D. The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
Answer: B
Explanation:
The Network Analytics Engine (NAE) in AOS-CX switches provides intelligent monitoring, troubleshooting, and performance analysis through predefined or custom scripts. Here's an analysis of the guidelines for NAE:
A: Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
* Correct:
* Each AOS-CX switch model has hardware and software limitations, including the number of agents and monitors it supports.
* Monitors are data collection points for tracking specific metrics like interface statistics, CPU usage, or custom-defined parameters.
* Agents are scripts that use monitors to evaluate data, trigger actions, or generate alerts.
* Since one agent can have multiple monitors, the total number of monitors might impact the scalability of agents.
B: You can install multiple scripts on a switch, but you can deploy only one agent per script.
* Incorrect:
* Multiple agents can be deployed from the same script if they monitor different parameters or have different configurations.
* The limitation is usually related to the total number of agents and monitors supported by the switch model, not the script itself.
C: The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
* Incorrect:
* AOS-CX enforces hardware and software limits on the number of agents and monitors. These limits are designed to prevent degradation of switch performance.
* You cannot deploy an unlimited number of agents, as the system enforces these restrictions.
D: When you use custom scripts, you can create as many agents from each script as you want.
* Incorrect:
* While you can use custom scripts to create agents, the total number of agents is subject to the switch's maximum supported limits.
* The scalability of agents is still bound by hardware and software constraints, even with custom scripts.

NEW QUESTION # 21
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?
- A. Its site-to-site VPN connections failing
- B. Its IDPS engine failing
- C. Traffic showing anomalous behavior
- D. Traffic matching a rule in the active ruleset
Answer: D
Explanation:
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.

NEW QUESTION # 22
You are using OpenSSL to obtain a certificate signed by a Certification Authority (CA). You have entered this command:
openssl req -new -out file1.pem -newkey rsa:3072 -keyout file2.pem
Enter PEM pass phrase: **********
Verifying - Enter PEM pass phrase: **********
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:California
Locality Name (eg, city) []:Sunnyvale
Organization Name (eg, company) [Internet Widgits Pty Ltd]:example.com
Organizational Unit Name (eg, section) []:Infrastructure
Common Name (e.g. server FQDN or YOUR name) []:radius.example.com
What is one guideline for continuing to obtain a certificate?
- A. You should submit file2.pem, but not file1.pem, to the desired CA to sign.
- B. You should submit file1.pem, but not file2.pem, to the desired CA to sign.
- C. You should use a third-party tool to encrypt file2.pem before sending it and file1.pem to the CA.
- D. You should concatenate file1.pem and file2.pem into a single file, and submit that to the desired CA to sign.
Answer: B
Explanation:
When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem.
The CA uses the information in the CSR to create and sign the certificate.
1.CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.
2.Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor's server.
3.Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.
Reference: OpenSSL documentation and best practices for obtaining and managing certificates emphasize the importance of keeping the private key secure and only submitting the CSR to the CA.

A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server to authenticate managers on its AOS-CX switches. You want to assign managers to groups on the AOS-CX switch by name.
How do you configure this setting in a CPPM TACACS+ enforcement profile?
- A. Add the Aruba:Common service and set Aruba-Admin-Role to the group name.
- B. Add the Aruba:Common service and set Aruba-Priv-Admin-User to the group name.
- C. Add the Shell service and set autocmd to the group name.
- D. Add the Shell service and set priv-Ivl to the group name.
Answer: A
Explanation:
To assign managers to groups on the AOS-CX switch by name using HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server, you should add the Aruba service to the TACACS+ enforcement profile and set the Aruba-Admin-Role to the group name. This configuration ensures that the appropriate administrative roles are assigned to managers based on their group membership, allowing for role-based access control on the AOS-CX switches.
NEW QUESTION # 24
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?
- A. The switch load balances client traffic across the primary and standby gateway configured in the UBT zone.
- B. The switch tunnels all users' traffic to the gateway configured as the primary gateway in the UBT zone, unless that gateway fails.
- C. The switch tunnels each user's traffic to the particular gateway assigned as that user's active user designed gateway.
- D. The switch tunnels all users' traffic to the gateway assigned as the switch's active device designated gateway.
Answer: C
Explanation:
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.
NEW QUESTION # 25
A company uses HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application option). In the details for a generic device cluster, you see a recommendation for "Windows 8/10" with 70% accuracy.
What does this mean?
- A. CPDI has used MAC OUI to group these devices together. The average device's MAC address matches
70% of the "Windows 8/10" OUI. - B. CPDI has detected that these devices match about 70% of the system rule for defining "Windows 8/10" devices.
- C. CPDI has grouped this cluster with similar classified devices. 70% of those classified devices are
"Windows 8/10." - D. CPDI has matched these devices against several, conflicting system rules. 70% of those rules are for
"Windows 8/10" devices.
Answer: B
Explanation:
When HPE Aruba Networking ClearPass Device Insight (CPDI) shows a recommendation for "Windows 8
/10" with 70% accuracy for a generic device cluster, it means that CPDI has detected that these devices match about 70% of the system rule criteria for defining "Windows 8/10" devices. This percentage indicates the confidence level based on the observed characteristics and behavior of the devices, helping administrators understand the likelihood that these devices are indeed running Windows 8 or 10.

NEW QUESTION # 27
You manage AOS-10 APs with HPE Aruba Networking Central. A role is configured on these APs with these rules (in order):
* Allow UDP on port 67 to any destination
* Allow any to network 10.1.4.0/23
* Deny any to network 10.1.0.0/18 + log
* Deny any to network 10.0.0.0/8
* Allow any to any destination
You add this new rule immediately before rule 4:
* Deny SSH to network 10.1.0.0/21 + denylist
After this change, what happens when a client assigned to this role sends SSH traffic to 10.1.7.12?
- A. The traffic is dropped and logged
- B. The traffic is dropped (without any logging or further action against the client)
- C. The traffic is permitted
- D. The traffic is dropped, and the client is denylisted
Answer: A
Explanation:
Aruba firewall / role access rules are evaluated top-down, first-match wins; once a rule matches, no later rules are processed.
Let's walk the packet through the ordered rules:
* The traffic is SSH, not UDP/67 # rule 1 does not match.
* Destination 10.1.7.12 is not in 10.1.4.0/23 # rule 2 does not match.
* 10.1.7.12 is in 10.1.0.0/18 # rule 3 matches first.
* Rule 3 action: Deny any to 10.1.0.0/18 + log.
* Because rule 3 already matched, the later "Deny SSH to 10.1.0.0/21 + denylist" rule is never evaluated, so no denylist is applied.
Aruba documentation for session ACLs and firewall rules explicitly states that rules are evaluated from top to bottom and "the first match terminates further evaluation," and logging/denylist flags on a rule are applied only when that specific rule matches.
So the outcome is: the SSH traffic is dropped and logged, but the client is not denylisted # Option B.
NEW QUESTION # 28
A company has HPE Aruba Networking APs managed by HPE Aruba Networking Central. You have set up a WLAN to enforce WPA3 with 802.1X authentication.
What happens if the client fails authentication?
- A. The AP assigns the client to the WLAN's initial role.
- B. The AP assigns the client to the WLAN's critical role.
- C. The AP assigns the client to the WLAN's default role.
- D. The AP drops the client because authentication aborts.
Answer: D
Explanation:
When WPA3 with 802.1X authentication is enforced on an HPE Aruba Networking WLAN, the authentication process strictly adheres to security standards. Here's how the process works:
1. 802.1X Authentication Workflow in WPA3
* The client must provide valid credentials (such as certificates or username/password) to authenticate with the RADIUS server via 802.1X.
* If the client fails authentication (e.g., due to invalid credentials or lack of proper configuration), the
802.1X handshake fails, and the AP terminates the connection.
2. Role Assignment in WLANs
* Default Role: The role assigned to authenticated clients after a successful 802.1X authentication. It is not applied to unauthenticated clients.
* Critical Role: This is a fallback role applied when there are issues communicating with the RADIUS server, not when authentication fails.
* Initial Role: A temporary role assigned to clients before authentication completes. However, this role is removed once the authentication process determines failure.
3. Behavior Upon Authentication Failure
* In the case of an authentication failure, the client does not get assigned to any role (default, critical, or initial) because it does not meet the conditions for network access.
* The client is dropped immediately, and no further communication is allowed until reauthentication is attempted.
Explanation of Each Option
* A. The AP assigns the client to the WLAN's default role:
* Incorrect: The default role applies only after successful authentication, not in case of authentication failure.
* B. The AP drops the client because authentication aborts:
* Correct: If the client fails authentication, the AP terminates the connection without assigning any roles.
* C. The AP assigns the client to the WLAN's critical role:
* Incorrect: The critical role is used when the AP cannot reach the RADIUS server, not when authentication fails.
* D. The AP assigns the client to the WLAN's initial role:
* Incorrect: The initial role is applied during the authentication process, but it is not retained after a failed authentication.

NEW QUESTION # 29 
You have downloaded a packet capture that you generated on HPE Aruba Networking Central. When you open the capture in Wireshark, you see the output shown in the exhibit.
What should you do in Wireshark so that you can better interpret the packets?
- A. Edit preferences for IEEE 802.11 and chose to ignore the Protection bit with IV.
- B. Apply the following display filter: wlan.fc.type == 1.
- C. Edit the Enabled Protocols and make sure that 802.11, GRE, and Aruba_ERM are enabled.
- D. Choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0.
Answer: D
Explanation:
To better interpret the packets shown in the Wireshark capture, you should choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0. This configuration will allow Wireshark to properly decode and display the Aruba-specific encapsulated remote mirroring (ERM) packets, providing a clearer understanding of the traffic.
1.Decoding Protocols: Selecting the correct protocol decoding in Wireshark ensures that the captured packets are interpreted correctly, displaying the relevant information.
2.Aruba ERM: The packets in the capture are likely encapsulated remote mirroring (ERM) packets specific to Aruba, which require proper decoding settings in Wireshark.
3.Clear Interpretation: By setting the Aruba ERM Type to 0 and decoding the packets as ARUBA_ERM, you can view the encapsulated data accurately.
Reference: Wireshark documentation and Aruba network packet analysis guides provide instructions on setting protocol decoding options to accurately interpret specific types of network traffic, such as Aruba ERM packets.
