1Which of the following best distinguishes a security threat from a security vulnerability in HPE Aruba Networking terminology?

A.A threat is an actor or event that can exploit a weakness; a vulnerability is the weakness itself

B.A threat is an unpatched system; a vulnerability is the attacker behind it

C.A threat is always external; a vulnerability is always internal

D.A threat is a confirmed compromise; a vulnerability is only theoretical

Explanation: In Aruba security training, a threat is any entity or circumstance with the potential to cause harm, while a vulnerability is a weakness in a system, configuration, or process that a threat can exploit. The two concepts are related but distinct: vulnerabilities exist independently of attackers, and threats become real risk only when they can reach a vulnerability.

2An attacker positions a rogue device between a wireless client and a legitimate AP, terminates the client's session, and forwards traffic to the real AP while reading the data. Which class of attack is this?

A.Distributed denial of service

B.Man-in-the-middle

C.Zero-day exploit

D.Privilege escalation

Explanation: A man-in-the-middle (MITM) attack inserts the attacker into the communication path between two endpoints so traffic can be observed or modified while both ends believe they are communicating directly. Wireless evil-twin and ARP-poisoning attacks are common MITM variants on Aruba networks.

3Which statement best describes a zero-day vulnerability?

A.A vulnerability disclosed for less than 24 hours

B.A vulnerability that exists before a vendor patch or signature is publicly available

C.A vulnerability discovered during the first day of a penetration test

D.A vulnerability rated CVSS 0.0 because it has no impact

Explanation: A zero-day vulnerability is a flaw that is exploited or known to attackers before the vendor has issued a patch and before defenders have a signature or mitigation. Defenders have zero days of advance notice, which is why behavior-based detection and segmentation are emphasized as compensating controls.

4An employee receives an email pretending to be from IT asking for credentials to 'reactivate' VPN access. Which threat category does this represent?

A.Social engineering

B.Buffer overflow

C.Cross-site scripting

D.ARP poisoning

Explanation: Social engineering attacks manipulate users into revealing information or taking actions that compromise security. Phishing emails impersonating IT are a classic social engineering technique covered in the HPE6-A78 threats objective.

5Which Aruba defense-in-depth principle states that a user, device, or process should be granted only the access strictly required to perform its function?

A.Implicit trust

B.Least privilege

C.Network of last resort

D.Vendor-verified access

Explanation: Least privilege limits each principal to the minimum access required for its role. Aruba's role-based access control, downloadable user roles, and dynamic segmentation are all expressions of least privilege for users and devices on the network.

6Aruba's Zero Trust Security framework is most accurately summarized by which of the following?

A.Trust devices on the corporate VLAN, verify guests at the edge

B.Never trust, always verify, and continuously assess every user and device

C.Encrypt all traffic and disable internal authentication

D.Use one strong perimeter firewall as the only enforcement point

Explanation: Zero Trust assumes no implicit trust based on network location and requires authentication, authorization, and continuous assessment for every user and device session. Aruba's reference architecture combines ClearPass for identity and posture, dynamic segmentation for enforcement, and Aruba Central/AIOps for continuous visibility.

7Which Public Key Infrastructure (PKI) component issues and signs digital certificates used for 802.1X EAP-TLS on an Aruba network?

A.Registration Authority (RA)

B.Certificate Authority (CA)

C.OCSP responder

D.Certificate Revocation List (CRL) distribution point

Explanation: The Certificate Authority (CA) is the trusted entity that signs and issues certificates. ClearPass Onboard can act as a CA, or it can integrate with an enterprise CA such as Microsoft AD CS to issue user and device certificates used for EAP-TLS.

8On a ClearPass Onboard deployment that issues device certificates, which mechanism most reliably tells the network to reject a stolen laptop's certificate without changing every authentication policy?

A.Disable the user account in Active Directory

B.Revoke the certificate so it appears on the CRL or OCSP

C.Lower the certificate's validity period

D.Remove the laptop from the Endpoints database

Explanation: Revocation is the PKI control for invalidating a certificate before it expires. ClearPass publishes a CRL and supports OCSP so that authenticators learn the certificate is no longer valid. Onboard maintains the per-device certificate so revocation can be performed for a single endpoint.

9Which TLS/PKI element does an Aruba controller present to a wireless supplicant during EAP-TLS authentication so the supplicant can verify the RADIUS server's identity?

A.The supplicant's user certificate

B.The RADIUS server certificate signed by a trusted CA

C.The pre-shared key derived from the SSID password

D.An IPsec security association

Explanation: In EAP-TLS the RADIUS server (ClearPass Policy Manager in most Aruba deployments) presents a server certificate that the supplicant validates against a trusted root CA. This protects against rogue RADIUS servers and is foundational to mutual authentication.

10Which protocol does ClearPass Policy Manager (CPPM) use to authenticate 802.1X clients on an Aruba controller or AOS-CX switch?

A.RADIUS

B.TACACS+

C.SNMPv3

D.LDAP referral

Explanation: CPPM uses RADIUS as the AAA transport for 802.1X user authentication. The Aruba authenticator (controller, gateway, or AOS-CX switch) sends Access-Request messages and receives Access-Accept with role/VLAN attributes that drive enforcement.

About the Aruba Network Security Associate Exam

The HPE Aruba Networking Certified Associate - Network Security (HPE6-A78) certification, formerly the Aruba Certified Network Security Associate (ACNSA), validates associate-level network security skills on the HPE Aruba Networking stack. The exam covers describing and combating common security threats and vulnerabilities, device hardening, AAA at the edge with 802.1X and MAC authentication, role-based access and dynamic segmentation with downloadable user roles, ClearPass Policy Manager and its OnBoard/OnGuard/Guest/Insight extensions, captive portal, basic WIDS/WIPS analysis, log collection, and forensic investigation procedures. The credential absorbed the legacy ACCA (ClearPass Associate) and is the on-ramp to the HPE7-A02 professional security certification.
