CAS-004 Timed Practice Test 2 — 10 Questions

Question 1

A healthcare organization is planning to migrate patient data to a cloud provider. The risk assessment identifies that the provider's SOC 2 report does not cover HIPAA controls. What is the BEST course of action?

Accepted Answer

Require the provider to sign a Business Associate Agreement (BAA). Option B is correct because a BA agreement is required under HIPAA to ensure the provider contractually agrees to safeguard ePHI. Option A is wrong because the risk assessment should drive decisions, not just acceptance. Option C is wrong because encryption does not eliminate the need for contractual protections. Option D is wrong because a SOC 2 report without HIPAA coverage does not suffice.

Answer

Request the provider's most recent SOC 3 report

Answer

Accept the risk and proceed with migration

Answer

Require the provider to encrypt all data at rest and in transit

Question 2

An organization's risk appetite is defined as 'low' for data privacy. Which of the following risk treatments is most aligned with this appetite?

Accepted Answer

Avoid the risk by not collecting unnecessary personal data. With a 'low' risk appetite for data privacy, the organization must minimize exposure to privacy breaches. Avoiding the risk by not collecting unnecessary personal data is the most aligned treatment because it eliminates the privacy risk entirely rather than reducing or transferring it. This approach ensures no personal data exists to be compromised, directly supporting a low-risk appetite.

Answer

Transfer the risk through cyber insurance

Answer

Mitigate the risk by encrypting personal data

Answer

Accept the risk and self-insure

Question 3

An organization wants to ensure that its third-party vendors comply with the company's security policies. Which of the following is the MOST effective method?

Accepted Answer

Include security requirements in contracts and conduct periodic audits. Including security requirements in contracts and conducting periodic audits is the most effective method because it creates a legally binding obligation for vendors to adhere to the organization's security policies, and audits provide direct, verifiable evidence of compliance. Unlike self-assessments or certifications, audits allow the organization to actively inspect controls, configurations, and processes, ensuring ongoing adherence rather than relying on a point-in-time assertion. This approach aligns with the NIST SP 800-53 continuous monitoring framework and is a core principle of third-party risk management (TPRM) in the CAS-004 domain.

Answer

Require vendors to obtain ISO 27001 certification

Answer

Send annual self-assessment questionnaires

Answer

Perform quarterly penetration tests on vendor networks

Question 4

A security architect is designing a system that must comply with FedRAMP Moderate controls. The system will use a cloud service provider (CSP) that is already FedRAMP Authorized. What is the primary benefit of using this CSP?

Accepted Answer

The CSP's authorization can be reused, reducing the agency's assessment burden. The primary benefit of using a FedRAMP Authorized CSP is that the CSP has already undergone a rigorous third-party assessment and continuous monitoring process. This allows the agency to reuse the existing authorization (via the 'JAB' or agency Provisional Authorization), significantly reducing the time, cost, and effort required for the agency's own assessment and authorization (ATO) process. It does not eliminate the agency's responsibility for risk management or compliance with FedRAMP Moderate controls, but it leverages the CSP's proven security posture.

Answer

The agency no longer needs to conduct any risk assessments

Answer

The CSP guarantees 100% security

Answer

The system automatically complies with all international regulations

Question 5

A company's data classification policy labels all financial data as 'Confidential.' An employee accidentally emails a spreadsheet containing customer payment information to an unauthorized external party. Which type of control failure occurred?

Accepted Answer

Preventive control failure. A preventive control failure occurred because the organization lacked a technical safeguard—such as Data Loss Prevention (DLP) rules, email content filtering, or mandatory access controls—to block the outbound transmission of confidential financial data. Preventive controls are designed to stop unauthorized actions before they happen, and the absence of such a mechanism allowed the accidental email to be sent. The failure is not in detection or correction, but in the inability to prevent the data exfiltration at the point of transmission.

Answer

Corrective control failure

Answer

Administrative control failure

Answer

Detective control failure

Question 6

Which TWO of the following are examples of administrative controls? (Select TWO)

Accepted Answer

Security awareness training. Security awareness training (C) is an administrative control because it involves policies, procedures, and human behavior management rather than technical mechanisms. It educates users on security risks and compliance requirements, reducing the likelihood of social engineering or policy violations. This aligns with the administrative domain of the CIA triad's governance framework.

Answer

Firewall rules

Answer

Encryption of data at rest

Answer

Intrusion detection system

Question 7

Which of the following is the PRIMARY purpose of a business impact analysis (BIA)?

Accepted Answer

Identify critical business processes and their impact if disrupted. The primary purpose of a business impact analysis (BIA) is to identify critical business processes and quantify the operational and financial impact if they were disrupted. This foundational step determines which systems and functions are essential to the organization's survival, directly informing the selection of recovery strategies and objectives. Without a BIA, continuity planning lacks a data-driven basis for prioritizing resources.

Answer

Identify vulnerabilities and threats

Answer

Determine recovery time objectives (RTOs)

Answer

Develop continuity strategies

Question 8

Which THREE of the following are common challenges when implementing a vendor risk management program? (Select THREE)

Accepted Answer

Lack of visibility into vendor security practices. A is correct because organizations often lack visibility into vendor security practices, meaning they cannot verify whether vendors comply with security policies or contractual obligations. This challenge arises when vendors do not provide access to their security controls, audit reports, or real-time monitoring data, leaving gaps in the risk assessment process.

Answer

Over-automation of risk scoring

Answer

Excessive cooperation from vendors

Question 9

You are the security architect for a mid-sized e-commerce company that processes credit card payments. The company must comply with PCI DSS. Currently, the cardholder data environment (CDE) includes a web server, an application server, and a database server, all on the same flat network segment. The QSA has identified that the CDE is not properly segmented, and network access controls are insufficient. The company wants to minimize the scope of PCI compliance by reducing the number of systems that handle cardholder data. You propose implementing network segmentation to isolate the CDE. Which of the following is the most effective approach to reduce PCI scope while maintaining business functionality?

Accepted Answer

Deploy a firewall between the CDE and corporate network, allowing only necessary traffic. Option D is correct because deploying a firewall between the CDE and the corporate network, and restricting traffic to only what is necessary, creates a proper network segmentation boundary. This isolation reduces the PCI DSS scope by ensuring that only systems within the CDE are subject to the full set of PCI requirements, while the corporate network remains out of scope. The firewall enforces a default-deny policy, which aligns with PCI DSS Requirement 1 for network segmentation and access control.

Answer

Encrypt all cardholder data at rest and in transit

Answer

Replace the database with a tokenization service and remove the database from the CDE

Answer

Move all servers to a DMZ and implement host-based firewalls

Question 10

A security architect is evaluating a new cloud-based application that will process sensitive customer data. The architect must ensure compliance with GDPR and PCI DSS. Which THREE of the following controls should be implemented? (Select THREE.)

Accepted Answer

Implement a process for customers to request deletion of their personal data.. Option B is correct because GDPR grants data subjects the right to erasure (Article 17), also known as the 'right to be forgotten.' Implementing a process for customers to request deletion of their personal data is a mandatory control for GDPR compliance, directly addressing this regulatory requirement.

Answer

Deploy geo-fencing to block access from non-EU countries.

Answer

Retain all access logs for a minimum of 7 years.
