NEW QUESTION # 67
Refer to the exhibit.
The BIG-IP Administrator is investigating disk utilization on the BIG-IP device. What should the BIG-IP Administrator check next? (Choose one answer)
Answer: C
Explanation:
When troubleshooting a BIG-IP system where a partition is reported as full (100% utilization), identifying and removing large or unnecessary files is the immediate next step for restoration of system stability.
* Symptoms of Full Partitions : If a file system (such as the root / or /var) becomes full, it can result in unpredictable system behavior, failure to save configurations, and the inability to log in to the Web UI.
* The Root (/) Partition : This partition is intentionally kept small on F5 systems. It is highly sensitive to the storage of third-party software or diagnostic files that should ideally be stored in the /shared or /var directories.
* Procedural Resolution : To resolve 100% disk usage, administrators should check for large files on the affected partition using CLI commands like du -ah or find / -xdev -type f -exec du {} \; | sort -rn | head
-20.
* Common Culprits : Large files typically causing these issues include old core files, tech support bundles, large diagnostic logs (packet diags), or temporary files created during administrative tasks.
* Diagnostics vs. Remediation : While tests like the EUD (End User Diagnostics) or platform diagnostics are useful for hardware verification, they do not resolve file system exhaustion issues that have already reached a critical 100% state.
NEW QUESTION # 68
Refer to the exhibit.
The BIG-IP Administrator runs the command shown and observes a device trust issue between BIG-IP devices in a device group. The issue prevents config sync on device bigip3.local. What is preventing the config sync?
Answer: C
Explanation:
Maintaining an accurate and synchronized clock across all members of a device group is a fundamental requir5ement for the BIG-IP Control P6lane to establis7h and maintain device tru8st9.
* Time Delta Impact : As shown in the exhibit, the " Time Delta to Local Device (sec) " is 12 .
* Trust Mechanism : Device trust relies on secure certificate-based communication (SSL/TLS) . If the time difference between devices is too large (typically more than a few seconds), the Control Plane cannot validate the certificates, leading to a failure in the trust relationship .
* ConfigSync Failure : When device trust is broken due to time drift, the systems cannot verify the identity of the peer, which directly prevents the ConfigSync process from executing on the affected device, such as bigip3.local in this scenario.
* Resolution : Administrators must ensure that all devices in a high availability pair are configured to use the same reliable NTP servers to keep their system clocks aligned.
The correct command for restoring an encrypted UCS archive via the command line is D. load /sys ucs < filepath > passphrase < password > .
NEW QUESTION # 69
A BIG-IP Administrator needs to check the memory utilization on a BIG-IP system. Which two methods can the BIG-IP Administrator use? (Choose two.)
Answer: A,D
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: Reporting device status includes monitoring physical resource exhaustion, such as memory48. The Control Plane provides both a command-line method via TMSH (show /sys memory) and a graphical method under Statistics > Module Statistics > Memory to report on how memory is allocated across TMM and the Linux host494949494949494949. This is essential for identifying potential "Aggressive Mode" triggers or hardware performance bottlenecks50.
NEW QUESTION # 70
The BIG-IP system is provisioned for LTM only. The BIG-IP Administrator is tasked with provisioning ASM. What process restarts when the BIG-IP Administrator changes the module provisioning? (Choose one answer)
Answer: B
Explanation:
When a BIG-IP Administrator changes module provisioning (for example, enabling ASM on a system previously provisioned only for LTM), the BIG-IP system must restart the Traffic Management Microkernel (TMM) process.
The TMM process is responsible for:
Traffic handling
LTM, ASM, and other traffic-processing modules
Enforcing security and application policies
Provisioning changes affect how traffic modules are loaded and integrated into TMM. As a result, TMM is restarted, which causes a temporary interruption of traffic processing. This is expected behavior and is why module provisioning changes should be planned during a maintenance window.
NEW QUESTION # 71
What are the recommended methods for forcing a BIG-IP system to standby mode? (Choose two answers)
Answer: B,D
Explanation:
BIG-IP provides two supported and documented methods to manually force a device into standby state in a high-availability (HA) configuration:
CLI method (A):
tmsh run /sys failover device standby
This is the correct and supported TMSH command to force the local device to transition from active to standby.
Configuration Utility method (B):
Navigating to Device Management > Devices > Local Device (Self) and selecting Force to Standby performs the same operation through the GUI and is fully supported.
