A server administrator notices that one server is intermittently NOT being sent any HTTP requests. The server logs display no issues. The LTM Specialist notices log entries stating the node (172.16.20.1) status cycling between down and up. The pool associated with the virtual server (10.10.1.100) has a custom HTTP monitor applied.
Which tcpdump filter will help trace the monitor?
- tcpdump -i internal port 80 and host 172.16.1.31
- tcpdump -i external port 80 and host 10.10.1.100
- tcpdump -i internal port 80 and host 172.16.1.33

An LTM Specialist is troubleshooting a new HTTP monitor on a pool. The pool member is functioning correctly when accessed directly through a browser. However, the monitor is marking the member as down. The LTM Specialist captures the monitor traffic via tcpdump.
What is the issue?
- The server is marking the connection as closed.
- The pool member is rejecting the monitor request.
- The monitor request is NOT returning the page body.
- The 'time-until-up' setting on the monitor is incorrect.

- import the hot fix to the /var/shared/images directory check the integrity of the file with an md5 checksum tmsh install sys software hotfix <hotfix_name>.iso volume <volume_name>
- import the hot fix to the /shared/images directory check the integrity of the file with an md5 checksum tmsh apply sys software hotfix volume <volume_name> <hotfix_name>.iso
- import the hot fix to the /shared/images directory check the integrity of the file with an md5 checksum tmsh install sys software hotfix <hotfix_name>.iso volume <volume_name>

Question 10
What is a benefit provided by F5 Enterprise Manager?
- Enterprise Manager allows administrators to analyze traffic flow and create custom application IPS signatures.
- Enterprise Manager allows administrators to establish baseline application usage and generate an alert if an administratively set threshold for the application is exceeded.
- Enterprise Manager allows administrators to identify application vulnerabilities. Virtual patches are then automatically generated and applied to remediate the detected application vulnerability.
- Enterprise Manager allows administrators to monitor all application traffic. Configuration optimization suggestions based on the observed traffic patterns are then generated for the administrator to review and apply.
