Q24. (Which of the following is a characteristic of a multizone region in a disaster recovery policy?)

Three or more availability zones

A single geographic location

Application high availability

Active/active deployment on secondary zones

The correct answer is C. Application high availability. CompTIA DataSys+ describes a multizone region as an architecture that deploys systems across multiple availability zones within the same geographic region to improve availability, fault tolerance, and resilience. Availability zones are physically separate data centers with independent power, cooling, and networking, but they are connected through low-latency links.
A key characteristic of a multizone disaster recovery (DR) design is high availability of applications. By distributing application components and databases across multiple zones, the system can continue operating even if one zone experiences a failure. DataSys+ emphasizes that multizone architectures are primarily designed to protect against localized infrastructure failures, such as power outages or hardware issues within a single zone, while maintaining service continuity.
Option A, three or more availability zones, is incorrect because a multizone region does not require a specific number of zones. Most implementations use two or more zones, and the exact count depends on the cloud provider and design requirements. Option B, a single geographic location, is misleading; while availability zones are within the same broader region, they are still separate physical locations and not a single data center. Option D, active/active deployment on secondary zones, more accurately describes a multi-region or advanced global DR strategy, not a basic multizone regional design. Secondary zones imply geographically separate regions used for regional disaster recovery.
CompTIA DataSys+ clearly distinguishes high availability from disaster recovery. Multizone deployments primarily focus on availability and fault tolerance within a region, while multi-region strategies address large- scale regional outages. In a multizone DR policy, applications are architected to remain available despite zone- level failures.
Therefore, the defining characteristic of a multizone region in a disaster recovery policy is application high availability, making option C the correct and fully verified answer.

Q25. Following a security breach, a database administrator needs to ensure users cannot change data unless a request is approved by the management team. Which of the following principles addresses this issue?

Open access

Least resistance

Elevated privilege

Least privilege

Q26. Which of the following is a result of an on-path attack on a system?

A Wi-Fi network that redirects to clones of legitimate websites

A website that has crashed and is no longer accessible

An email from an unknown source requesting bank account details

A web application that returns the addresses of its customers

Q27. A developer is designing a table that does not have repeated values. Which of the following indexes should the developer use to prevent duplicate values from being inserted?

Unique

Single column

Implicit

Composite

Q28. (A healthcare company relies on contact forms and surveys on its website to properly communicate with patients. To which of the following attacks is the company’s data most vulnerable?)

DoS

Ransomware

SQL injection

Brute-force

The correct answer is C. SQL injection. According to CompTIA DataSys+ objectives, web-based input mechanisms such as contact forms and online surveys represent a significant attack surface for databases if they are not properly secured. These forms commonly accept user-supplied input that is later processed by backend database queries. If input validation and parameterized queries are not correctly implemented, attackers can exploit this by injecting malicious SQL code into form fields.
SQL injection attacks allow an attacker to manipulate database queries executed by the application. This can result in unauthorized access to sensitive data, data modification, data deletion, or even full database compromise. In a healthcare environment, this risk is especially critical because patient data is highly sensitive and often protected by regulatory requirements. DataSys+ highlights SQL injection as one of the most common and dangerous database-focused attacks due to its direct impact on data confidentiality, integrity, and availability.
Option A, Denial of Service (DoS), primarily affects system availability by overwhelming resources, but it does not directly target data stored within the database. Option B, ransomware, typically requires malware execution on servers or endpoints and is not specifically tied to web form input mechanisms. Option D, brute- force attacks, focus on repeatedly guessing authentication credentials and are more closely associated with login systems rather than data entry forms or surveys.
CompTIA DataSys+ materials emphasize that databases connected to web applications must use strong input validation, stored procedures, prepared statements, and least-privilege database accounts to mitigate SQL injection risks. Because contact forms and surveys directly interact with database queries and rely on untrusted user input, SQL injection represents the most direct and realistic threat in this scenario.
Therefore, SQL injection is the attack type to which the company’s data is most vulnerable, making option C the verified and correct answer.

Q29. Which of the following is a reason to create a stored procedure?

To minimize storage space

To improve performance

To bypass case sensitivity requirements

To give control of the query logic to the user

The IP addresses for the users’ workstations changed.

The DNS permissions changed.

Q31. A developer is designing a table that does not have repeated values. Which of the following indexes should the developer use to prevent duplicate values from being inserted?

Unique

Implicit

Composite
