CompTIA DataSys+ Certification Exam Sample Questions (Q64-Q69):

NEW QUESTION # 64
Which of the following should a company develop to ensure preparedness for a fire in a data center?

Answer: B

Explanation:
The document that a company should develop to ensure preparedness for a fire in a data center is a disaster recovery plan. A disaster recovery plan is a document that outlines how an organization will continue its operations in the event of a disaster or disruption, such as fire, flood, earthquake, cyberattack, etc. A disaster recovery plan typically includes the following elements: - The objectives and scope of the plan - The roles and responsibilities of the staff involved - The identification and assessment of the risks and impacts - The strategies and procedures for restoring the critical functions and data - The resources and tools required for the recovery process - The testing and maintenance schedule for the plan A disaster recovery plan helps an organization to minimize the damage and downtime caused by a disaster, as well as to resume normal operations as soon as possible. The other options are either different types of documents or not specific to fire preparedness. For example, a deployment plan is a document that describes how a system or software will be installed or launched; a backup plan is a document that specifies how data will be copied and stored for backup purposes; a data retention policy is a document that defines how long data should be kept and when it should be deleted or archived.


NEW QUESTION # 65
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?

Answer: C

Explanation:
The principle that addresses this issue is least privilege. Least privilege is a security principle that states that users should only have the minimum level of access or permissions required to perform their tasks or roles. By applying this principle, the administrator can ensure that users cannot change data unless they have been authorized by the management team through a request approval process. This prevents unauthorized or accidental modifications of data that may compromise its integrity or security. The other options are either opposite or unrelated to this principle. For example, open access means that users have unrestricted access to data; least resistance means that users have the easiest or most convenient access to data; elevated privilege means that users have higher or more permissions than they need.


NEW QUESTION # 66
Which of the following types of RAID, if configured with the same number and type of disks, would provide the best write performance?

Answer: D

Explanation:
The type of RAID that would provide the best write performance if configured with the same number and type of disks is RAID 10. RAID 10, or RAID 1+0, is a type of RAID that combines mirroring and striping techniques to provide both redundancy and performance. Mirroring means that data is duplicated across two or more disks to provide fault tolerance and data protection.
Striping means that data is split into blocks and distributed across two or more disks to provide faster access and throughput. RAID 10 requires at least four disks and can tolerate the failure of up to half of the disks without losing data. RAID 10 provides the best write performance among the RAID types because it can write data in parallel to multiple disks without parity calculations or overhead. The other options are either different types of RAID or not related to RAID at all. For example, RAID 3 is a type of RAID that uses striping with a dedicated parity disk to provide redundancy and performance; RAID 5 is a type of RAID that uses striping with distributed parity to provide redundancy and performance; RAID 6 is a type of RAID that uses striping with double distributed parity to provide extra redundancy and performance.


NEW QUESTION # 67
Which of the following scripts would set the database recovery model for sys.database?

Answer: D

Explanation:
The script that would set the database recovery model for sys.database is option A. This script uses the ALTER DATABASE statement to modify the recovery model of the sys.database to full with no wait. The other options either have syntax errors, use incorrect keywords, or do not specify the recovery model correctly. Reference: CompTIA DataSys+ Course Outline, Domain 3.0 Database Management and Maintenance, Objective 3.1 Given a scenario, perform common database maintenance tasks.


NEW QUESTION # 68
Which of the following does a database administrator need to know before planning the setup of a new server for a client?

Answer: B

Explanation:
Knowing the size and importance of the server is crucial for proper planning, as it determines the required resources, configurations, and level of redundancy needed to meet the client's needs.
