HP HPE6-A88 Exam Questions Instant Access

Question 1

An organization is setting up a guest network using ClearPass and wants to ensure a seamless login experience for repeat visitors. Which approach should they take to achieve this goal while maintaining a reasonable level of security?

AImplement a fully secured 802.1X network for guest users.

BCombine MAC authentication with the captive portal authentication process.

CCreate a web login page without any additional authentication methods.

Answer : B

This approach is known as MAC Caching. During the first visit, the guest logs in via the captive portal. ClearPass then 'caches' the device's MAC address for a specific period (e.g., 24 hours or 1 week). When the user returns, the network device performs a MAC-based authentication; ClearPass recognizes the cached device and grants access immediately, allowing the guest to bypass the portal entirely for a 'seamless' experience.

Question 2

An IT administrator attempts to join a ClearPass server to an Active Directory domain. They notice that the system clocks of the ClearPass server and the AD domain are not in sync. The ClearPass server is 10 minutes behind the AD domain. As a best practice, what should the administrator do?

AThe administrator should manually set the ClearPass server clock to match the AD domain.

BThe administrator should sync the ClearPass server and the AD domain to the same time source.

CThe administrator should proceed with the join.

Answer : B

Manual time setting is a temporary fix and will inevitably drift. The best practice for any distributed system, especially one relying on Kerberos and Active Directory, is to sync all components to the same NTP (Network Time Protocol) source. By pointing both the ClearPass servers and the Domain Controllers to the same authoritative clock, the administrator ensures that the time difference remains near zero, preventing domain join failures and ensuring certificate validity and log accuracy across the entire infrastructure.

Question 3

A network engineer is reviewing the policy cache tab for an endpoint in the Identity: Endpoints Database. They notice the cache was updated three minutes ago. What can the engineer conclude about the current status of the endpoint's role or posture token?

AThe endpoint's role or posture token has expired and needs to be reassigned immediately.

BThe policy cache will not expire until the endpoint is disconnected from the network.

CThe endpoint's role or posture token is still valid and will be updated if necessary within the next two minutes.

Answer : C

Policy cache entries in ClearPass typically have a default life-cycle of 5 minutes. If the cache was updated three minutes ago, it has two minutes of validity remaining. During this time, ClearPass will use the cached roles and posture status for any incoming requests from that device. Once the 5-minute mark is reached, the cache expires, and ClearPass will perform a full re-evaluation on the next request.

Question 4

An IT administrator is managing a network with ClearPass and notices that one of the devices is sending multiple health checks throughout the day via different networks (wired, wireless, and VPN). How does OnGuard handle the license usage for this device?

AOnGuard debits one license per day for the device regardless of the number of health checks or networks used.

BOnGuard debits a license for each network the device connects to throughout the day.

COnGuard debits a separate license for each health check sent by the device.

Answer : A

ClearPass OnGuard licensing is based on the unique endpoint, not the number of connections or checks. A single device that connects via wired in the morning, Wi-Fi in the afternoon, and VPN in the evening---triggering a health check each time---will only consume one OnGuard license for that 24-hour period. This 'per-device' model makes licensing predictable for enterprise deployments with roaming users.

Question 5

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?

AThe client devices are not compliant with the network security policies.

BThe service is configured to reset posture and role status every time.

CThe 'Use Cached Results' option is not enabled on the enforcement tab.

Answer : C

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.

Question 6

A company has deployed ClearPass Onboard to manage their BYOD environment. They want to ensure that each device connecting to the network has a unique identity for auditing purposes. Which feature of ClearPass Onboard directly supports the company's need for unique device identities?

AClearPass Onboard supports anti-virus and firewall checks for device compliance.

BClearPass Onboard provides endpoint compliance and control capabilities.

CClearPass Onboard assigns a unique certificate to each device that goes through the Onboard process.

Answer : C

The core of ClearPass Onboard is a specialized Certificate Authority (CA). During the provisioning process, each device generates a unique private key and receives a unique identity certificate. This certificate is tied to both the user and the specific hardware. When the device authenticates via 802.1X (EAP-TLS), ClearPass logs the exact certificate used, providing a perfect audit trail of 'who' connected with 'which' specific personal device.

Question 7

An organization uses ClearPass to manage network access for its devices. A device reported as stolen is detected attempting to connect to the network. What action can the EMM server trigger upon receiving an HTTP API call from ClearPass?

AThe EMM server can automatically block all network traffic from the device.

BThe EMM server can send a message to the user or wipe the user's device.

CThe EMM server can permanently disable the device's network interface.

Answer : B

ClearPass and EMM/MDM integration provides 'Closed-Loop' security. When ClearPass identifies a 'Stolen' device status (either via its own database or a real-time check), it can use a Context Server Action to signal the EMM server. The EMM server, which has deep administrative control over the device OS, can then execute high-level security commands such as Remote Wipe (deleting all data) or displaying a 'Lock Screen' message to the person holding the device.
