The organization should retrieve the tapes from the cold site and test them to ensure they are properly maintained and usable during a DR scenario. A cold site is a location that has space and power for backup equipment, but no actual equipment installed or configured. The organization stores backup tapes of its servers at cold sites as a precaution in case of a disaster that affects its primary site. However, backup tapes can degrade over time due to environmental factors such as temperature, humidity, dust, or magnetic fields. Therefore, the organization should periodically retrieve the tapes from the cold site and test them on compatible equipment to verify their integrity and readability.

A tabletop exercise is a type of disaster recovery testing exercise that is primarily used to discuss incident response strategies for critical systems without affecting production data. A tabletop exercise is a discussion-based session where team members meet in an informal, classroom setting to review their roles and responsibilities during an emergency and their responses to a hypothetical scenario. A facilitator guides the participants through the discussion and evaluates the strengths and weaknesses of the preparedness program. A tabletop exercise does not involve any actual deployment of resources or activation of systems12. A backup recovery test (B) is a type of disaster recovery testing exercise that involves restoring data from backup media to verify its integrity and availability. A backup recovery test may affect production data if it is not performed on a separate environment. A live failover © is a type of disaster recovery testing exercise that involves switching operations from a primary site to a secondary site in case of a failure or disruption. A live failover may affect production data if it is not performed on a simulated environment. A hot-site visit audit (D) is a type of disaster recovery testing exercise that involves inspecting and evaluating a hot site, which is a backup location that has fully operational equipment and resources to resume business operations in case of a disaster. A hot-site visit audit does not involve any discussion of incident response strategies or simulation of scenarios.

RAID 6 is a type of RAID that uses block-level striping with two parity blocks distributed across all member disks. It allows for two disk failures within the RAID set before any data is lost1. A minimum of four disks is required to create RAID 61. To increase the size of an existing RAID 6 array, the administrator can replace the array drives one at a time with larger drives and then expand the array. This way, the data and parity are rebuilt on each new drive and the array remains operational during the process2.

The chmod command is used to change the permissions of files and directories. The g+w option means to grant write permission to the group owner of the file. Since Joe is a member of the IT group, which is also the group owner of the file, this command will allow him to save changes to the file without affecting the permissions of other users.
