CompTIA CAS-005 Exam With Confidence Using Practice Dumps

Understanding the Ransomware Issue:

The key issue here is thatbackups were not recoverable within the required RPO timeframe.

This means the organizationdid not properly testitsbackup and disaster recovery (DR) processes.

To prevent this from happening again, regular disaster recovery testing is essential.

Why Option C is Correct:

Disaster recovery testing ensures that backups are functionaland can meetbusiness continuity needs.

Frequent DR testingallows organizations to identify and fixgaps in recovery strategies.

Regular testing ensuresthat recoverymeets the RPO & RTO (Recovery Time Objective) requirements.

Why Other Options Are Incorrect:

A (Encrypt & label backup tapes):While encryption is important, it does not address thefailure to meet RPO requirements.

B (Reverting to manual business processes):While amanual continuity planis good for resilience, it doesnot resolve the backup and recovery failure.

D (Tabletop exercise & RACI matrix):Atabletop exerciseis a planning activity, butit does not involve actual recovery testing.

The best option is to provide sanitized devices with remote connections to a Virtual Desktop Infrastructure (VDI). This ensures that no sensitive intellectual property is stored locally on the laptops carried across borders. Even if the devices are inspected, seized, or tampered with, attackers cannot access corporate data since all sensitive files remain within secure, centralized infrastructure.

Option A (Measured Boot) reports firmware tampering but does not prevent data theft if the device is compromised. Option C (self-encrypting drives) protect data at rest but can be bypassed if customs agents demand login credentials. Option D (tamper-evident stickers) provide only physical inspection indicators and are ineffective against sophisticated data theft attempts.

CAS-005 emphasizes secure remote access strategies and temporary “clean laptops” for high-risk travel scenarios. Sanitized laptops with VDI access minimize exposure while maintaining productivity, making this the strongest mitigation.
