A server is reporting a hard drive S.M.A.R.T. error. When a technician checks on the drive, however, it appears that all drives in the server are functioning normally. Which of the following is the reason for this issue?

1. A. A S.M.A.R.
2. B. error is a predictive failure notic
3. C. The drive will fail in the near future and should be replaced at the next earliest time possible
4. D. A S.M.A.R.
5. E. error is a write operation erro
6. F. It has detected that the write sent to the drive was incorrectly formatted and has requested a retransmission of the write from the controller
7. G. A S.M.A.R.
8. H. error is simply a bad secto
9. I. The drive has marked the sector as bad and will continue to function properly
10. J. A S.M.A.R.
11. K. error is an ECC erro
12. L. Due to error checking and correcting, the drive has corrected the missing bit and completed the write operation correctly.

Correct Answer: A
A S.M.A.R.T. error is a predictive failure notice. The drive will fail in the near future and should be replaced at the next earliest time possible. S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a feature that monitors the health and performance of hard drives and alerts the user of any potential problems or failures. S.M.A.R.T. can detect various indicators of drive degradation, such as bad sectors, read/write errors, temperature, or spin-up time. If a S.M.A.R.T. error is reported, it means that the drive has exceeded a predefined threshold of acceptable operation and is likely to fail soon. The drive may still function normally for a while, but it is recommended to back up the data and replace the drive as soon as possible to avoid data loss or system downtime.

Which of the following BEST describes a warm site?

1. A. The site has all infrastructure and live data.
2. B. The site has all infrastructure and some data
3. C. The site has partially redundant infrastructure and no network connectivity
4. D. The site has partial infrastructure and some data.

Correct Answer: D
A warm site is a type of disaster recovery site that has some pre-installed hardware, software, and network connections, but not as much as a hot site. A warm site also has some backup data, but not as current as a hot site. A warm site requires some time and effort to become fully operational in the event of a disaster. A hot site is a disaster recovery site that has all infrastructure and live data, and can take over the primary site’s operations immediately. A cold site is a disaster recovery site that has no infrastructure or data, and requires significant time and resources to set up. References:

An application server's power cord was accidentally unplugged. After plugging the cord back in the server administrator notices some transactions were not written to the disk array. Which of the following is the MOST likely cause of the issue?

1. A. Backplane failure
2. B. CMOS failure
3. C. Misconfigured RAID
4. D. Cache battery failure

Correct Answer: D
A cache battery is a battery that provides backup power to the cache memory of a disk array controller. The cache memory stores data that is waiting to be written to the disk array. If the cache battery fails, the data in the cache memory may be lost or corrupted when the power is interrupted. Verified References: [Cache battery], [Disk array controller]

Which of the following BEST describes a guarantee of the amount of time it will take to restore a downed service?

1. A. RTO
2. B. SLA
3. C. MTBF
4. D. MTTR

Correct Answer: A
RTO stands for Recovery Time Objective and it is a metric that defines the maximum acceptable amount of time that a system or service can be unavailable after a disaster or disruption. RTO is part of the business continuity planning and disaster recovery planning processes. RTO ensures a guarantee of the amount of time it will take to restore a downed service by setting a target or goal for recovery. RTO can vary depending on the criticality and priority of the service.References: https://www.comptia.org/training/resources/exam-objectives/comptia-server-sk0-005-exam- objectives (Objective 3.3)

An administrator is researching the upcoming licensing software requirements for an application that usually requires very little technical support. Which of the following licensing models would be the LOWEST cost solution?

1. A. Open-source
2. B. Per CPU socket
3. C. Per CPU core
4. D. Enterprise agreement

Correct Answer: A
Open-source software is software that is freely available and can be modified and distributed by anyone. It usually requires very little technical support and has no licensing fees. Therefore, it would be the lowest cost solution for an application that does not need much support.References: https://www.comptia.org/training/resources/exam- objectives/comptia-server-sk0-005-exam-objectives (Objective 2.3)
