Final answer:
CompTIA classifies scanning as part of the recovery validation effort. Rebuilding systems, sanitization, and secure disposal may be part of the recovery process, but they are not specifically classified as part of the recovery validation effort by CompTIA.
Step-by-step explanation:
CompTIA classifies scanning as part of the recovery validation effort. Scanning is the process of examining systems and networks for vulnerabilities or potential threats. It helps identify any areas that need to be addressed in order to ensure the recovery process is successful.
Rebuilding systems may be part of the recovery process, but it is not specifically classified as part of the recovery validation effort by CompTIA.
Sanitization and secure disposal are important steps in the recovery process, but they are not specifically classified as part of the recovery validation effort by CompTIA.
