F5 BIG-IP Administration Support and Troubleshooting 認定 F5CAB5 試験問題 (Q81-Q86):質問 # 81
resume is enabled and a health check first fails and then passes?
  • A. Available (Enabled)
  • B. Offline (Disabled)
  • C. Offline (Enabled)
  • D. Available (Disabled)
正解：B
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents: 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.

質問 # 82
A BIG-IP Administrator suspects that one of the BIG-IP device power supplies is experiencing power outages. Which log file should the BIG-IP Administrator check to verify the suspicion?
  • A. /var/log/ltm
  • B. /var/log/kern.log
  • C. /var/log/daemon.log
  • D. /var/log/audit
正解：A
解説：
On a BIG-IP system, hardware-related alerts, including those for power supply units (PSUs), fans, and chassis components, are primarily logged in the Local Traffic Manager (LTM) log file.
* Log Location: The file path is /var/log/ltm.
* PSU Alert Messages: When a power supply fails, experiences an outage, or is unplugged, the chmand (Chassis Manager) or system_check processes log specific error codes to this file. For example, you may see messages like 010d0006:0: Chassis power supply <X> has experienced an issue or VINPUT=bad.
* Troubleshooting: Administrators can use the command grep -i "power supply" /var/log/ltm to quickly filter for PSU-related events.
* Other Logs: * /var/log/kern.log typically contains low-level kernel and driver messages.
* /var/log/audit tracks administrative changes and commands executed by users.
* /var/log/daemon.log contains messages from various system background services but is not the primary location for hardware sensor alerts.

質問 # 83
Refer to Exhibit. An organization is reporting slow performance accessing their Intranet website, hosted in a public cloud. All employees use a single Proxy Server with the public IP of
104.219.110.168 to connect to the Internet. What should the BIG-IP Administrator of the Intranet website do to fix this issue?

  • A. Change Source Address to 104.219.110.168/32
  • B. Change Load Balancing Method to Least Connection
  • C. Change Default Persistence Profile to cookie
  • D. Change Fallback Persistence Profile to source_addr
正解：C
解説：
This scenario describes a classic network performance issue known as the "Mega-Proxy" problem. When an organization routes all employee traffic through a single proxy server, the BIG- IP sees thousands of unique users as having the exact same source IP address. If the administrator has configured "Source Address Affinity" persistence, the BIG-IP will correctly follow the rule but incorrectly route all users to the same single backend pool member. This creates a severe load imbalance where one server is overwhelmed while others remain idle, leading to poor application response times. To resolve this, the administrator must change the persistence profile to "HTTP Cookie". Cookie-based persistence allows the BIG-IP to place a unique identifier in each user's browser, allowing the system to distinguish between individual sessions even if they share the same source IP. This fix ensures that traffic is distributed evenly across the pool members, restoring the expected load balancing functionality and resolving the slow performance reported by users behind the corporate proxy.

質問 # 84
Which command restarts a BIG-IP service?
  • A. stop sys traffic
  • B. show sys service
  • C. restart sys service <service_name>
  • D. reload sys config
正解：C
解説：
Used to restart specific system services.

質問 # 85
Which menu should you use on the BIG-IP Configuration Utility to generate a QKView support file? (Choose one answer)
  • A. System > Configuration
  • B. System > Support
  • C. System > Logs
  • D. System > Archive
正解：B
解説：
Comprehensive and Detailed 150 to 250 Words Explanation From BIG-IP Administration, Support, and Troubleshooting Documents:
AQKViewfile is the primary diagnostic support bundle used by F5 Support to troubleshoot BIG-IP system issues. It contains comprehensive system information, including running configuration, licensing details, module provisioning, hardware status, software versions, log files, statistics, and the output of numerous diagnostic commands. Generating a QKView is a standard and recommended first step when investigating performance problems, configuration issues, or when opening a support case with F5.
In the BIG-IP Configuration Utility (GUI), the correct and supported location to generate a QKView isSystem
> Support. This menu is specifically designed for support and troubleshooting operations. From this section, administrators can generate a QKView file, monitor its creation progress, download it locally, or upload it directly to F5 iHealth for automated analysis. This workflow is clearly documented in BIG-IP Administration and Support guides and aligns with F5 best practices.
The other menu options are not appropriate:
* System > Configurationis used for system-wide settings such as DNS, NTP, and device identity.
* System > Archiveis used to create UCS backup files, which are configuration backups, not diagnostic bundles.
* System > Logsis used only for viewing system logs, not generating support files.
Therefore,System > Supportis the correct and only valid answer.
