Sample HPE6-A88 Questions
Practice with real exam-style questions, each with the verified correct answer and explanation.
An IT administrator notices that endpoints are being re-evaluated with the same enforcement decisions even after client status changes. They realize this is causing inefficient network access control. What could be the underlying issue?
While caching can sometimes cause issues (as seen in Q76), enabling 'Use Cached Results' is often necessary for efficiency in complex multi-stage authentications. If this is not enabled, ClearPass may fail to properly correlate new status changes (like a profile update) with the existing session, leading the system to revert to a default or previous decision rather than dynamically adjusting the access based on the latest context.
An organization using SAN records in their certificates wants to ensure all hostnames are properly validated. What critical step must they take?
Modern browsers and operating systems (such as iOS and newer versions of Windows/Android) often ignore the Common Name (CN) if Subject Alternative Name (SAN) fields are present. If an administrator puts the primary hostname in the CN but forgets to repeat it in the SAN list, the client device may reject the certificate as 'Invalid'. Best practice is to include every possible FQDN and hostname the server might be accessed by within the SAN section.
A network administrator is troubleshooting connectivity issues between clients and the ClearPass server. They suspect that the firewall configuration might be causing the problem. Which action should the administrator take to ensure the OnGuard agent can properly communicate with the ClearPass server?
Communication between the OnGuard agent and ClearPass requires specific firewall ports to be open. TCP Port 443 (HTTPS) is used for the initial control channel and software updates. TCP Port 6658 is the proprietary port used for the agent's 'heartbeat,' which provides real-time health updates and session monitoring. If either port is blocked, the agent will appear offline or fail to report its posture status.
An IT administrator is setting up a captive portal for a company's network and needs to ensure that the SSL certificate is compatible with the Aruba Instant device they are using. Which type of certificate should the administrator install to meet this requirement?
Network access devices, including Aruba Instant APs and controllers, generally require certificates in the PEM (Privacy Enhanced Mail) format. PEM certificates are Base64 encoded and are standard for Unix-based systems and networking hardware because they can easily include the entire trust chain (server, intermediate, and root certificates) in a single text file.
An IT administrator is configuring ClearPass to send guest receipts for registrations. They want to ensure that guests receive these receipts through both email and SMS simultaneously. What steps should the administrator follow to achieve this configuration?
System-wide notification settings are managed under Administration > External Servers > Messaging Setup. To support simultaneous delivery, both the Email Relay (SMTP) and the SMS Gateway must be fully configured and tested within this menu. This centralizes the messaging logic, allowing various Guest and Insight services to utilize these pre-configured channels for automated alerts and receipts.
