   A GTM administrator is replacing a failed BIG-IP DNS system under RMA. The replacement hardware is running the same BIG-IP version as the failed unit. The administrator has a UCS backup from the failed unit and has completed the initial setup on the replacement. After restoring the UCS, the administrator notices that the GTM service is running, but the wide IPs are not resolving. The administrator checks the DNS listeners and sees they are bound to the correct self-IPs. What is the most likely cause of the wide IPs not resolving?

   • AThe DNS listeners are not configured to answer queries for the wide IP domains.
   • BThe zone files for the wide IP domains were not restored or are out of date.
   • CThe GTM service needs to be restarted to load the restored wide IP configuration.
   • DThe wide IPs are not enabled after the restore and must be manually activated.

   A GTM system has failed and is being replaced under an RMA. The replacement hardware has been received and is running the same BIG-IP version as the failed unit. The administrator has a UCS backup from the failed unit. What is the correct sequence of steps to restore the GTM service on the replacement hardware?

   • ARecreate the GTM configuration manually on the replacement and then restore the UCS to merge the settings.
   • BRestore the UCS immediately after powering on the replacement, before completing the initial setup.
   • CPerform the initial setup on the replacement, restore the UCS, and then verify GTM objects and DNS resolution.
   • DRestore the UCS, then reconfigure the management IP address to match the failed unit's address.

   A GTM administrator is restoring a UCS backup to a BIG-IP DNS system. The backup was taken 60 days ago, and since then, several zone files have been updated with new records. The administrator wants to ensure that the current zone files are not lost during the restore. What is the best approach?

   • AExport the current zone files to a remote location before performing the UCS restore.
   • BTake a new UCS backup immediately before the restore to include the current zone files.
   • CDisable zone file restoration in the UCS restore settings.

   A GTM administrator is planning to restore a UCS backup to a BIG-IP DNS system. The current system has zone files that have been updated with new records since the backup was taken. The administrator wants to preserve the current zone files while restoring the rest of the GTM configuration. What is the best approach?

   • ABack up the current zone files separately and restore them after the UCS restore completes.
   • BTake a new UCS backup immediately before the restore to include the current zone files.
   • CDisable zone file restoration in the UCS restore settings.
   • DUse the merge option during the UCS restore to combine the current zone files with the backup.

   A GTM administrator restores a UCS backup to a BIG-IP DNS system. After the restore, the GTM is serving DNS responses, but the zone file for a customer domain is missing several recently added records. The administrator confirms the records were present in the current zone file before the restore. What is the most likely explanation for the missing records?

   • AThe zone file was not included in the UCS backup and was recreated from scratch, missing the recent additions.
   • BThe zone file was synchronized with a secondary DNS server after the restore, which removed the records.
   • CThe UCS backup contained an older version of the zone file, which overwrote the current version during the restore.
   • DThe zone file was corrupted during the restore process, causing the records to be dropped.
