SK0-005 Exam Dumps - CompTIA Server+ Questions and Answers

Comprehensive and Detailed Explanation:

Data Loss Prevention (DLP) policies are designed to detect and prevent unauthorized transmission of sensitive data outside the organization. Implementing DLP helps monitor and control data flows, ensuring proprietary information remains within the company.​

RAID 5 configuration: Using five of the available drives in a RAID 5 configuration meets the requirements for:

Storage capacity: Four 600GB drives (2, 5, and 6) provide a total usable capacity of 2.4TB (4 * 600 * 0.8), exceeding the minimum requirement of 2TB. RAID 5 introduces parity data for fault tolerance, sacrificing some usable space (one drive's worth).

Performance: The combination of multiple drives in a RAID 5 array improves read performance compared to a single drive setup.

Fault tolerance: Even with a single drive failure (any of the five drives used in the RAID 5), the remaining drives can reconstruct the lost data, allowing the server to continue operating.

When a server that previously received updates from a Windows Server Update Services (WSUS) server suddenly fails to do so, one common cause is that the local software firewall is blocking the necessary ports or services required for WSUS communication. Firewalls can be reconfigured, either intentionally or accidentally, leading to such connectivity issues.

Biometric lockis a physical security feature but does not restrict access to motherboard software directly.

Data-at-rest encryptionprotects data stored on the system's hard drives but does not secure the BIOS or firmware.

Bootloader authenticationensures that the operating system's boot process is secured, but it is not a method to restrict access to the motherboard's software.

An emergency change request is a type of change request that is initiated in response to an urgent situation, such as a system breach, that requires immediate action to restore normal operations or prevent further damage. An emergency change request may bypass some of the normal change management procedures, such as approval, testing, or documentation, in order to expedite the implementation of the change. However, an emergency change request should still follow the basic steps of change management, such as identification, analysis, planning, execution, and evaluation, and should be reviewed and documented after the change is completed.

RAID 5 is efficient for read-heavy workloads but is not well-suited for applications that perform many small reads and writes due to the overhead of parity calculations. To improve performance while maintaining redundancy:

RAID 0 (A): This would improve performance but does not offer any data protection, making it unsuitable.

RAID 1 (B): Provides redundancy but does not enhance write performance significantly.

RAID 6 (C): Offers better fault tolerance than RAID 5 but suffers from even higher write penalties due to double parity.

RAID 10 (D): Combines mirroring (RAID 1) and striping (RAID 0), significantly improving both read and write performance while ensuring redundancy. This makes it the best choice for applications with high-frequency small reads/writes.

Since the administrator needs higher performance and data protection, RAID 10 is the best choice.

A DNS entry is a record that maps a domain name to an IP address. If the DNS entry for the new application is incorrect, users will not be able to resolve the domain name to the correct IP address and port number. This will prevent them from accessing the application, even if the firewall rules allow port 8443. To fix this issue, the server administrator should verify and update the DNS entry for the new application.

The next step to troubleshoot the issue after developing and testing a theory is to establish an action plan. This involves identifying the steps needed to implement the solution, estimating the time and resources required, and evaluating the potential risks and impacts of the solution. Documenting the findings and actions, escalating the issue to the management team, or implementing the solution are steps that should be done after establishing an action plan. References: [CompTIA Server+ Certification Exam Objectives], Domain 6.0: Disaster Recovery, Objective 6.2: Explain troubleshooting theory and methodologies.

Port 443 is used for HTTPS, which is a secure version of HTTP that encrypts the data between the web server and the client. Port 3389 is used for RDP, which is a protocol that allows remote desktop connections to a server. These ports should be allowed for a secure web server that can be administered via RDP.
