質問 # 52
Refer to the exhibit.
A pool member fails the monitor checks for about 30 minutes and then starts passing the monitor checks. New traffic is NOT being sent to the pool member. What is the likely reason for this problem? (Choose one answer)
正解：A
解説：
In BIG-IP LTM, health monitors are used to determine if a pool member or node is "Up" and capable of processing traffic. Based on the provided exhibit, the specific configuration setting causing this behavior is Manual Resume.
Manual Resume (Enabled/Yes): When the Manual Resume setting is set to Yes, it changes the default behavior of how a pool member returns to service. Under normal circumstances (Manual Resume set to No), once a pool member starts passing its health check again, the BIG-IP system automatically marks it as "Up" and resumes sending traffic to it. However, with Manual Resume enabled, the system will continue to mark the pool member as "Down" (or "Unavailable") even after it passes the health check. It requires a manual intervention by an administrator to reset the status and allow traffic to flow again.
Exhibit Analysis: The screenshot clearly shows the Manual Resume radio button is selected as Yes. This explains why, even after the pool member "starts passing the monitor checks," it does not receive new traffic.
Incorrect Options Analysis:
Time Until Up (0 seconds): This setting defines how long a member must consistently pass health checks before being marked "Up." If it is set to 0, it should actually return to service immediately upon the first successful check.
The pool member is disabled: While a disabled member won't receive traffic, the question focuses on why passing a monitor check didn't restore service, which points specifically to the monitor configuration shown.
Monitor Type is TCP Half Open: This is simply the method used to check the service (sending a SYN and expecting a SYN-ACK, then sending a RST). It determines how the check is performed, not what happens after the check succeeds.

The BIG-IP appliance fails to boot. The BIG-IP Administrator needs to run the End User Diagnostics (EUD) utility to collect data to send to F5 Support. Where can the BIG-IP Administrator access this utility?
正解：C
解説：
The End User Diagnostics (EUD) utility is a hardware-level testing suite used to verify the integrity of the physical components of a BIG-IP appliance.
* Access Requirements: Because the EUD must be run while the TMOS operating system is not loaded (typically when the device cannot boot or requires hardware validation), it cannot be accessed via network-based interfaces like the Management Port or VLANs.
* Console Connection: The administrator must connect a terminal to the physical Console Port (using a serial cable) to interact with the boot menu.
* Execution Process: Upon restarting the appliance, the administrator must intercept the boot process at the GRUB menu and select the "End User Diagnostics" option. All output and menu selections are then handled through the serial console session.
質問 # 54
What information is required for a BIG-IP Administrator to open an F5 Support ticket?
正解：C
解説：
To ensure a support case is processed and routed efficiently, F5 specifies a mandatory set of baseline information.
* Serial Number: Required to verify the support contract and entitlement level for the hardware or virtual edition.
* QKView: This is described as the "first and most important thing to have when opening a case". It provides the F5 Support Engineer with the necessary diagnostic data to understand the system's current state and resource utilization.
* Problem Description: A precise description of the issue, including symptoms, when the problem started, and the business impact, is critical for routing the case to the correct technical team.
* Contact Info: Accurate contact information for the individual who will be working on the ticket with F5.
* Comparison: While packet captures (Option A) or UCS files (Option B) are often useful, they are not strictly required for the initial opening of all support tickets; however, a QKView is considered a primary prerequisite for technical analysis.
質問 # 55
A gateway_icmp health monitor is configured on a pool. The BIG-IP Administrator is investigating why the pool is reported as down while the server is online. Other pools with servers in the same subnet are correctly monitored.
What can cause this behavior? (Choose one answer)
正解：D
解説：
A gateway_icmp monitor checks basic network reachability by sending ICMP echo requests (pings) to the pool member or its gateway. If the pool is marked DOWN while the server is confirmed to be online, the most likely cause is that ICMP traffic is being blocked.
A host-based firewall active on the server (Option C) can block ICMP echo requests or replies, preventing BIG-IP from receiving a successful response to the health check. This results in the monitor failing and the pool member being marked down, even though the server and application are otherwise functioning normally. This explanation is consistent with the scenario where other servers in the same subnet work correctly, indicating that routing and BIG-IP configuration are not the issue.
The other options are unrelated to ICMP monitoring. Logged-in users (Option A), missing patches (Option B), and stopped HTTP services (Option D) do not affect a gateway_icmp monitor. BIG-IP troubleshooting best practices recommend verifying ICMP reachability and firewall policies when diagnosing ICMP-based monitor failures.
質問 # 56
In an F5 BIG-IP system, a pool is configured with a health monitor and the "Manual Resume" feature is Enabled. If a pool member is marked Offline (Red) due to a health monitor failure, what will be the status of the member once the health monitor successfully passes again?
正解：C
解説：
The "Manual Resume" feature is a safety mechanism used when a pool is not working as expected due to flapping services or unstable backend applications. Normally, when a health monitor fails, the pool member is marked "Offline" (Red), and when the monitor passes, it automatically returns to "Available" (Green)47. However, if "Manual Resume" is enabled, the BIG-IP will not automatically put the member back into rotation after a failure48. Even if the health check begins to pass again, the member remains in an "Offline (Disabled)" state49. This requires an administrator to manually intervene and re-enable the member. This is a common point of confusion when troubleshooting; a member may show passing health checks but still not receive traffic because it is waiting for a manual administrative "resume" command. This feature is intended to prevent "unhealthy" servers from receiving traffic until an engineer has confirmed the root cause of the initial failure was resolved.
