Pass the CompTIA CompTIA Server+ SK0-005 Questions and answers with CertsForce

Abusiness impact analysis (BIA)is a document that outlines the potential effects of downtime on business operations. It identifies critical business functions and estimates the impact of disruption on the organization's ability to function.

Business impact analysis (Answer D):This document is specifically designed to assess the consequences of downtime and other disruptions.

Service-level agreement (Option A):Defines the expected level of service between a provider and a client but doesn't directly explain downtime consequences.

Business continuity plan (Option B):Outlines how the business will continue operating during a disruption but doesn’t focus solely on the consequences of downtime.

Disaster recovery plan (Option C):Focuses on restoring systems after a disaster but doesn’t outline the specific impact of downtime.

CompTIA Server+ Reference:This topic relates toSK0-005 Objective 4.1: Explain disaster recovery concepts.

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.​

The server is shutting down after being powered on, which could indicateoverheating. This is a common issue whenfans fail, causing the CPU or other components to overheat and forcing the system to shut down to protect itself from damage.

Check for fan failure (Answer B):Ensuring the server’s cooling system is functioning properly is crucial. Overheating due to a fan failure can cause the system to shut down automatically.

Resetting memory modules (Option A):While memory issues can cause system instability, they generally do not lead to immediate shutdowns as described.

Changing the VM password (Option C):This is unrelated to the shutdown issue.

Setting credentials for the remote console (Option D):This is irrelevant to the described problem of server shutdown.

CompTIA Server+ Reference:This topic is related toSK0-005 Objective 3.3: Diagnose hardware and software issues.

A faulty PSU needs replacement, and the management team wants a solution to prevent future downtime.

Solution: Implement redundancy (Option D):

Redundant power supplies ensure that if one fails, the other takes over seamlessly.

Separate circuits, load balancing, and server monitoring are important but do not directly prevent PSU failures.

When selecting a RAID level, both redundancy and storage efficiency must be considered:

RAID 1 mirrors data, providing high redundancy but reducing available storage to 50%. With eight drives, only four drives' worth of space would be available.

RAID 5 uses striping with distributed parity. It provides good storage efficiency (n-1) but can only tolerate one drive failure.

RAID 6 is similar to RAID 5 but uses dual parity, allowing two drives to fail while still maintaining data integrity. However, it reduces available storage to (n-2).

RAID 10 (also known as RAID 1+0) combines mirroring and striping. It provides excellent redundancy and performance, allowing multiple drive failures as long as they aren't in the same mirrored pair. Storage efficiency is 50%, but the redundancy and performance benefits outweigh this trade-off in high-availability environments.

Since the technician requires both maximum redundancy and high available storage, RAID 10 is the best choice.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:Event logsare the primary source for tracking server reboots and other system events. Logs such as the system log in Linux (/var/log/syslog or /var/log/messages) or the Event Viewer in Windows provide timestamps and details about shutdowns, restarts, and boot processes. Regular monitoring ensures that unplanned reboots or system errors are identified and addressed.

Uptime:Indicates how long the server has been running since the last reboot but does not provide detailed reboot evidence.

IOPS:Refers to input/output operations per second, unrelated to reboots.

CPU utilization:Reflects processor activity but offers no reboot evidence.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:Scripting is commonly used to automate repetitive step-by-step tasks in server management, such as:

Automating system configurations.

Running maintenance jobs like backups or log file cleanup.

Performing administrative tasks like provisioning new users or setting permissions.

This automation improves efficiency and reduces the likelihood of human error. Referencing the SK0-005 guide, scripting is a best practice for simplifying tasks that involve consistent, repeatable processes.

Multi-Factor Authentication (MFA) requires the use of two or more different authentication factors to verify a user’s identity. The three main authentication factors are:

Something You Know – Password, PIN, security questions

Something You Have – Smart card, key fob, RFID chip

Something You Are – Biometrics such as fingerprint, retina scan

Option C (RFID chip and PIN code) meets the MFA requirement because:

RFID chip (Something You Have) provides a physical security token.

PIN code (Something You Know) adds a knowledge-based authentication factor.

Other Options:

A. Retinal scan and fingerprint reader: Both are biometric factors (Something You Are) and do not satisfy MFA requirements, which need at least two different categories.

B. Key fob and employee badge: Both are physical items (Something You Have), failing to meet MFA requirements.

D. An alphanumeric, case-sensitive password with symbols: This only represents Something You Know, not MFA.

Thus, RFID chip and PIN code (Option C) provides two separate authentication factors and meets the MFA policy requirements.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:Blanking panelsare used to fill empty spaces in server racks. By blocking airflow gaps between servers, blanking panels help to direct airflow properly, ensuring that the cold air from the cold aisle is not wasted and that the hot air from the hot aisle is contained. This is crucial for maintaining the efficiency of cooling systems in a hot/cold aisle configuration.

Rack balancingaddresses the physical distribution of equipment, but it does not directly address thermal issues.

Higher-capacity PDUs(Power Distribution Units) provide more power, but they do not address cooling or airflow problems.

Rail kitsare used for mounting servers and are unrelated to cooling efficiency.

After an update, if a core service fails to start, potential causes include dependencies, authentication, or incomplete updates:

The server requires another reboot to complete the rollback (A): Some updates require multiple reboots, but if rolling back did not resolve the issue, a missing dependency is more likely.

The administrator is not authorized to run the service (B): If the administrator previously had access and the update broke the service, it is likely due to software conflicts rather than permissions.

The server requires further updates of other software components (C): Many services rely on dependent libraries, drivers, or patches. If an update replaces or removes a necessary component, the service may fail until additional updates are applied.

The account used to run the service has expired (D): Expired accounts usually cause authentication failures but not outright service crashes unless explicitly required for the update process.

Since rolling back the update did not fix the issue, the most likely reason is that additional updates or dependencies are missing.
