CompTIA Updated CAS-004 Exam Questions and Answers by lylah

Option A (Origin assurance): Digital signatures ensure that the code originates from a trusted source.

Option B (Integrity verification): Digital signatures verify that the code has not been tampered with since it was signed.

Option C (Confidentiality): Digital signatures do not provide encryption or confidentiality.

Option D (DRMs): Digital signatures are not specifically related to Digital Rights Management.

Option E (Recipient verification): Digital signatures validate the sender, not the recipient.

Option F (Free of malware): While digital signatures verify integrity, they cannot guarantee that the code is free of malware.

In the event of a fire at the main data center, the immediate action should be to review and engage the disaster recovery plan. This is to ensure the continuity of business operations. The CIO should coordinate with IT leaders from both companies to ensure a unified response. Assessing the damage and planning for recovery are crucial, and leveraging the expertise from both companies can help streamline the process.

A downgrade attack likely exploited the outdated OpenSSL version, allowing the attacker to bypass secure encryption and impersonate the user. Upgrading to a secure version of OpenSSL and disabling older versions is critical. This aligns with CASP+ objective 1.5, emphasizing the importance of securing cryptographic implementations.

Caching is the most appropriate solution to improve response time for static content, such as sponsor-related data on the entry pages. Caching stores frequently accessed data closer to users, reducing the need to retrieve it from the database repeatedly. This results in faster load times, especially during high-traffic events. While scalability (horizontal or vertical) might address overall system performance, caching specifically targets improving the speed of accessing static content. CASP+ emphasizes caching as a performance optimization technique for handling high-demand, static web content.
