Explanation

Cisco Expressway backups are tightly coupled to the software version that created them. A backup can only be restored to an Expressway running the exact same software version as the one that generated the backup. Attempting to restore a backup to a different software version will fail. This is because the configuration schema, database structure, and binary components are version-specific. Option A is incorrect - software version is critically relevant. Option B is incorrect because Cisco does support restoring a backup to a different physical Expressway server (a replacement unit), provided the software version matches. Option C is incorrect because the encryption/decryption password set during backup creation is mandatory during restore; without it, the encrypted backup cannot be decrypted.
