DS0-001 Exam Dumps - CompTIA DataSys+ Questions and Answers

 The category of SQL commands that is required to revoke access to database objects is DCL. DCL, or Data Control Language, is a subset of SQL commands that are used to control or manage the access or permissions of users or roles on a database. DCL includes commands such as GRANT and REVOKE. GRANT is a DCL command that is used to grant privileges or roles to users or roles on specific objects in a database, such as tables, views, procedures, etc. REVOKE is a DCL command that is used to revoke privileges or roles from users or roles on specific objects in a database. For example, the following statement uses the REVOKE command to revoke the SELECT privilege from user Alice on table employee:

REVOKE SELECT ON employee FROM Alice;

The other options are either different categories of SQL commands or not related to SQL commands at all. For example, IDDL is not a valid acronym or category of SQL commands; IDML is not a valid acronym or category of SQL commands; TCL, or Transaction Control Language, is a subset of SQL commands that are used to control or manage transactions on a database, such as committing or rolling back changes. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.

A result of an on-path attack on a system is a Wi-Fi network that redirects to clones of legitimate websites. An on-path attack is a type of attack that intercepts and modifies the traffic between two parties without their knowledge or consent. An attacker can use an on-path attack to create a rogue Wi-Fi network that mimics a legitimate one, and then redirect the users to fake websites that look like the ones they intended to visit. The attacker can then steal the users’ personal or financial information, such as usernames, passwords, credit card numbers, or bank account details. The other options are either results of different types of attacks or not related to attacks at all. For example, a website that has crashed and is no longer accessible may be a result of a denial-of-service attack, an email from an unknown source requesting bank account details may be a result of a phishing attack, and a web application that returns the addresses of its customers may be a result of a poor design or a data breach. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.4 Given a scenario, identify common types of attacks against databases.

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.

The correct order of the steps in the database deployment process is option C. This order follows the best practices for deploying a database system, which are:

Confirm prerequisites: Check the system requirements and compatibility of the database software and tools before installation.

Install: Install the database software and tools on the target server or platform.

Configure: Configure the database settings and parameters according to the specifications and needs of the application or organization.

Connect: Connect the database to the network and other systems or applications that will access it.

Test: Test the functionality and performance of the database system and verify that it meets the expectations and requirements.

Validate: Validate the data quality and integrity of the database system and ensure that it complies with the standards and regulations.

Release: Release the database system to production and make it available for use by end-users or customers. The other options do not follow this order and may result in errors, inefficiencies, or security issues. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.1 Given a scenario, install and configure database software and tools.

The attack in which an attacker hopes to profit from locking the database software is ransomware. Ransomware is a type of malware that encrypts the data or files on a system or network and demands a ransom from the victim to restore them. Ransomware can target database software and lock its access or functionality until the victim pays the ransom, usually in cryptocurrency. Ransomware can cause serious damage and loss to the victim, as well as expose them to further risks or threats. Ransomware can be delivered through various methods, such as phishing emails, malicious attachments, compromised websites, etc. The other options are either different types of attacks or not related to locking database software at all. For example, spear phishing is a type of phishing attack that targets a specific individual or organization with personalized or customized emails; SQL injection is a type of attack that inserts malicious SQL statements into an input field or parameter of a web application to manipulate or compromise the underlying database; on-path is a type of attack that intercepts and modifies the data in transit between two parties on a network. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.4 Given a scenario, identify common types of attacks against databases
