CompTIA CompTIA Server+ SK0-005 Questions & Answers

• Question 371:

  An organization implements split encryption keys for sensitive files. Which of the following types of risks does this mitigate?

  A. Hardware failure

  B. Malware

  C. Data corruption

  D. Insider threat

  Correct Answer: D

  An insider threat is a type of risk that can be mitigated by implementing split encryption keys for sensitive files. An insider threat is a malicious actor who has authorized access to an organization's system or data and uses it for unauthorized or harmful purposes. An insider threat can cause data breaches, sabotage, fraud, theft, espionage, or other damages to the organization. Split encryption keys are a method of encrypting data using multiple keys that are stored separately and require collaboration to decrypt. Split encryption keys can prevent an insider threat from accessing or compromising sensitive data without being detected by another authorized party who holds another key. Hardware failure is a type of risk that involves physical damage or malfunction of hardware components such as hard drives, memory modules, power supplies, or fans. Hardware failure can cause data loss, system downtime, performance issues, or other problems for the organization. Hardware failure cannot be mitigated by split encryption keys, but by backup, redundancy, monitoring, and maintenance measures.

• Question 372:

  An administrator is installing a new file server that has four drive bays available. Which of the following RAID types would provide the MOST storage as well as disk redundancy?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 10

  Correct Answer: D

  RAID 10 would provide the MOST storage as well as disk redundancy out of the given options.

  RAID 0 provides no redundancy and only offers increased performance by striping data across multiple drives.

  RAID 1 provides disk redundancy but only half the total storage capacity since each disk is a mirror of the other.

  RAID 5 provides a good balance of storage and redundancy by striping data across multiple disks with parity data distributed among the disks. However, it requires at least three drives and can only withstand the failure of one disk.

  RAID 10, also known as RAID 1+0, provides both disk redundancy and increased storage capacity by mirroring two drives and then striping data across the mirrored pairs. This configuration requires at least four drives and can withstand the

  failure of one drive in each mirrored pair.
