   An administrator is investigating a disk space issue on a BIG-IP. The 'df -h' output shows /var is 90% full. The administrator runs 'du -sh /var/log' and sees that /var/log is 10G. The administrator also runs 'ls -lh /var/log/ltm' and sees that the ltm log file is 8G. What is the most likely cause of the disk space issue?

   • AThe /var/log directory is mounted on a separate partition that is too small.
   • BThe system is logging at a debug level, which is causing excessive log growth.
   • CThe /var/log directory contains too many small files, consuming inodes.
   • DThe /var/log/ltm log file is excessively large and is the primary consumer of disk space.

   An administrator is investigating why a BIG-IP is running out of disk space on /var. The 'df -h' output shows /var is 100% full. The administrator runs 'du -sh /var/*' and sees the following: /var/log 15G, /var/tmp 5G, /var/config 1G, /var/run 500M. What is the most likely cause of the disk full issue?

   • AThe /var/log directory is consuming the most space, likely due to excessive logging.
   • BThe /var/run directory is consuming too much space due to runtime files.
   • CThe /var/config directory is consuming too much space due to configuration files.
   • DThe /var/tmp directory is consuming too much space due to temporary files.
