HP Aruba Certified Network Security Professional Exam HPE7-A02 Prüfungsfragen mit Lösungen (Q39-Q44):

39. Frage
Refer to the exhibits.

You are setting up HPE Aruba Networking ClearPass Policy Manager (CPPM) to authenticate wireless clients with EAP-TLS and 802.1X. CPPM should assign clients to an AOS firewall role named contractors- fullaccess if the clients meet these requirements:
* AD account is enabled: AccountStatus 512
* Security group name is Contractors
What should you do to make these policies meet these requirements?

A. In the role mapping policy rule 2, change "role2" to a role named "contractors-fullaccess."
B. In the enforcement policy rule 1, change the profile to a RADIUS enforcement profile with the Aruba- User-Role attribute set to contractors-fullaccess .
C. In the enforcement policy rule 1, remove the second condition; also change the profile to one named
"contractors-fullaccess."
D. Add this rule to the enforcement policy: IF Tips:Role EQUALS role2 , THEN profile = RADIUS enforcement profile with the Aruba-User-Role attribute set to contractors-fullaccess .

Antwort: B

Begründung:
The role mapping policy is configured to Evaluate all , so a client with an enabled AD account receives role1
, and a client in the Contractors group receives role2 . A client that meets both requirements receives both roles. The enforcement policy uses First applicable , and rule 1 already checks for both conditions: Tips:
Role EQUALS role1 AND Tips:Role EQUALS role2 . Therefore, the matching logic is already correct.
What is missing is the correct enforcement action. To assign an AOS firewall role, CPPM must return the appropriate RADIUS enforcement profile containing the Aruba-User-Role VSA set to contractors-fullaccess
. Changing only role mapping names does not assign the firewall role. Adding a separate role2-only rule would incorrectly match Contractors users whose AD account status is not enabled.

40. Frage

The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?

A. Specify at least two server names under the "Connect to these servers" field.
B. Under the "Connect to these servers" field, use a wildcard in the server name.
C. Select the desired Trusted Root Certificate Authority and select the check box next to "Don't prompt users."
D. Clear the check box for using simple certificate selection and select the desired certificate manually.

Antwort: A

Begründung:
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.

41. Frage
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 (without any logging or further action against the client)
B. The traffic is dropped, and the client is denylisted
C. The traffic is dropped and logged
D. The traffic is permitted

Antwort: C

Begründung:
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.

42. Frage
A company uses HPE Aruba Networking APs running AOS-10, HPE Aruba Networking Central, and HPE Aruba Networking ClearPass Policy Manager (CPPM). After starting to implement TEAP to authenticate wireless clients, admins notice that all clients are showing up on APs and in HPE Aruba Networking Central with the "anonymous" username. They want to see users' actual names there.
What can they do to address this issue?

A. Configure the HPE Aruba Networking Central group settings to enable deep packet inspection and firewall visibility on all HPE Aruba Networking APs.
B. On CPPM, edit the AD authentication source and add a custom attribute that collects the username.
C. On the APs, make sure that RADIUS proxy is disabled. Also ensure that all APs are added as network devices on CPPM.
D. Have CPPM apply an additional RADIUS enforcement profile to authenticated clients, which specifies the TEAP Method 2 username.

Antwort: D

Begründung:
TEAP can use an anonymous outer identity to protect user privacy during the EAP exchange.
That is why APs and Aruba Central might display "anonymous" instead of the authenticated username. To make the actual username visible, CPPM must return the correct identity attribute after authentication. Applying an additional RADIUS enforcement profile that specifies the TEAP Method 2 username allows the infrastructure to display the real authenticated user identity.
Editing the AD source does not solve what identity is returned to the AP. DPI and firewall visibility are unrelated to RADIUS identity reporting. Disabling RADIUS proxy or adding APs as network devices might help other deployments, but it does not directly replace anonymous TEAP identity reporting.

43. Frage
What is a benefit of Online Certificate Status Protocol (OCSP)?

A. It lets a device dynamically renew its certificate before the certificate expires.
B. It lets a device download all the serial numbers for certificates revoked by a CA at once.
C. It lets a device query whether a single certificate is revoked or not.
D. It lets a device determine whether to trust a certificate without needing any root certificates installed.

Antwort: C

Begründung:
The benefit of the Online Certificate Status Protocol (OCSP) is that it allows a device to query whether a single certificate is revoked or not. OCSP provides a real-time mechanism for checking the revocation status of an individual certificate, enabling devices to verify the validity of certificates quickly and efficiently.
1.Certificate Status Query: OCSP enables devices to send a query to an OCSP responder to check the revocation status of a specific certificate.
2.Real-Time Verification: This protocol offers real-time responses, ensuring that the most up-to-date status of the certificate is obtained.
3.Efficiency: OCSP is more efficient than downloading an entire Certificate Revocation List (CRL), as it only queries the status of one certificate at a time.
