The HPE Aruba Networking ClearPass Advanced Product Certified exam (HPE6-A88) is a 50-question, 90-minute proctored Pearson VUE test with a 70% passing score and a fee around $230 USD. It validates ClearPass-specific NAC skills across Policy Manager services, AAA (RADIUS, TACACS+, 802.1X with EAP-TLS/PEAP, MAC Auth), Guest captive portal workflows, OnBoard certificate provisioning, OnGuard posture, dynamic user roles and segmentation, and ClearPass cluster administration. The exam is delivered in English, Japanese, and Latin American Spanish, and the credential is valid for three years.

1Which best describes Network Access Control (NAC) as implemented by HPE Aruba Networking ClearPass?
A.A perimeter firewall product
B.A policy engine that authenticates users and devices and authorizes their level of network access based on identity, posture, and context
C.A wireless intrusion prevention system
D.A SIEM that only logs authentication events
Explanation: ClearPass is an Aruba NAC platform that authenticates endpoints (users, devices, IoT), evaluates contextual attributes (location, time, posture, profile), and authorizes their access via RADIUS/TACACS+ enforcement. It does not replace a firewall, IDS, or SIEM.
2A ClearPass administrator wants to enforce different VLANs and ACLs on a single SSID based on whether the connecting device is a corporate laptop, BYOD smartphone, or a printer. Which ClearPass capability makes this possible?
A.Only RADIUS shared secrets
B.Role-based access control delivered through enforcement profiles tied to authentication and authorization results
C.Static MAC filtering at the AP
D.Captive portal only
Explanation: ClearPass evaluates a service's policies, computes a role using role-mapping policies, and returns an enforcement profile (RADIUS attributes such as Aruba-User-Role, VLAN, downloadable role) so the NAS applies the correct VLAN/ACL per session. One SSID can serve many roles.
3Which standards-based protocol does ClearPass use to push a mid-session policy change (for example moving a posture-failed device into a quarantine role) to a controller without waiting for the next authentication?
A.SNMPv3
B.RADIUS Change of Authorization (CoA) per RFC 3576/5176
C.HTTPS to the AP CLI
D.802.11k action frames
Explanation: RADIUS CoA (RFC 3576, updated by RFC 5176) lets ClearPass send Disconnect-Request or CoA-Request messages to the NAS to terminate or modify an active session. ClearPass uses CoA when posture changes, when an admin bounces a session, or when ClearPass Exchange triggers occur.
4Which statement about ClearPass and Zero Trust is most accurate?
A.ClearPass replaces all firewalls in a Zero Trust design
B.ClearPass enforces continuous identity-, device-, and posture-based access decisions and shares context with other security tools to support Zero Trust
C.ClearPass is unrelated to Zero Trust
D.Zero Trust requires ClearPass to be installed inline at the data plane
Explanation: ClearPass aligns with Zero Trust by validating identity, device posture, and context for every access request, by reauthorizing sessions when context changes (CoA), and by exchanging context with firewalls, EDR, MDM, and SIEM through ClearPass Exchange.
5An administrator wants ClearPass to share endpoint context (role, posture status, profile) with a third-party firewall for adaptive segmentation. Which ClearPass component is designed for this purpose?
A.ClearPass OnGuard
B.ClearPass Exchange (Context Server Actions / Endpoint Context Servers)
C.ClearPass Insight
D.ClearPass Onboard
Explanation: ClearPass Exchange uses Endpoint Context Servers and Context Server Actions to push and pull endpoint context (user, role, posture, profile) to/from third-party systems such as Palo Alto, Check Point, EDR, MDM, and SIEM. Insight, OnGuard, and Onboard cover other roles.
6Which best describes the value of network segmentation enforced through ClearPass dynamic roles?
A.Faster Wi-Fi throughput
B.Reducing the blast radius of a compromise by restricting east-west traffic per identity and device class
C.Lower power draw on switches
D.Replacing the need for VLANs
Explanation: Per-identity, per-device segmentation limits lateral movement: a compromised IoT camera can only reach its specific server, and a contractor cannot reach finance servers. ClearPass distributes this segmentation through user-role/VLAN/ACL assignments at authentication.
7Which protocol does ClearPass use as the AAA transport for 802.1X-authenticated wired and wireless network access?
A.TACACS+
B.RADIUS (UDP 1812 auth, 1813 accounting)
C.SSH
D.SMB
Explanation: 802.1X relies on RADIUS as the AAA backend. ClearPass listens on UDP 1812 (auth) and 1813 (accounting) by default and supports RadSec (RADIUS over TLS, TCP 2083) for encrypted transport.
8Which ClearPass feature lets you encrypt RADIUS traffic between ClearPass and a NAS over TLS rather than using only the shared secret?
A.RadSec (RADIUS over TLS, TCP 2083)
B.RadiusGuard
C.SNMPv3
D.TACACS+
Explanation: RadSec (RFC 6614) tunnels RADIUS over TLS on TCP 2083, providing confidentiality and integrity beyond the legacy shared-secret model. Each NAS presents a TLS client certificate that ClearPass validates.
9An IoT camera does not support 802.1X. Which ClearPass-supported authentication method is most appropriate for granting it network access while still applying a role?
A.EAP-TLS only
B.MAC Authentication (MAC Auth) with a service that maps the MAC to a role via static host list, endpoint database, or profile
C.Captive portal
D.Kerberos
Explanation: For headless devices, ClearPass uses MAC Authentication: the NAS sends the device MAC as username/password in a RADIUS request, and ClearPass authorizes against a static host list, the endpoint repository, or profile-derived attributes, then returns the appropriate role.
10Which use case is best handled by combining ClearPass Profile (Device Insight) with MAC Authentication?
A.Replacing 802.1X for managed laptops
B.Identifying unknown devices by their fingerprints (DHCP, HTTP UA, MAC OUI, SNMP, NMAP, Active Sync) and using the discovered category in policy
C.Encrypting RADIUS traffic
D.Issuing client certificates
Explanation: Profile passively and actively fingerprints endpoints, classifying them (e.g., 'Apple iPad', 'Axis Camera'). The resulting Category/Family/Name attributes can be matched in role-mapping or service rules so that, for example, all 'IP-Camera' devices land in an IoT role even though they only do MAC auth.
