comptia server+ practice test Intermediate Practice Exam: Medium Difficulty 2025

A technician is installing a new RAID controller in a rack server. The controller includes a battery-backed cache module to improve write performance. Which action is MOST important to ensure data integrity during a power loss event?

A data center is adding a second power supply to an existing server to improve availability. After installation, the server still powers off when one power feed is cut during maintenance. Which change will BEST provide power redundancy for that server?

An administrator wants to deploy a new application server quickly and consistently across multiple environments (test, staging, production). The OS must be standardized, and deployments should be repeatable with minimal manual steps. Which approach BEST meets this requirement?

A company is moving a workload to a virtualized cluster. The application requires low latency disk access and must remain available during host maintenance. Which solution BEST supports these requirements?

An administrator is troubleshooting authentication issues after joining a Linux server to an enterprise directory service. Users can authenticate locally but not with domain credentials. Network connectivity to the directory servers is verified. Which action is the MOST appropriate next step?

A security team requires that administrative access to servers be tightly controlled and auditable. Administrators currently share a single privileged account to log in via SSH/RDP. Which change BEST meets the requirement while maintaining operational efficiency?

A company needs to protect a file server from ransomware while ensuring the ability to restore files to a clean point in time. The backup repository must be resilient to deletion or encryption by compromised admin credentials. Which solution BEST addresses this requirement?

A server in a remote branch must be secured in a small wall-mounted rack that is accessible to non-IT staff. The organization wants to reduce the risk of data exposure if a drive is removed and also wants to prevent accidental disconnects. Which combination of controls is BEST?

A server intermittently reboots under load. Logs show thermal warnings shortly before each reboot. The server is in a rack with several adjacent devices. Which action should be performed FIRST to address the issue?

After replacing a failed disk in a RAID 5 array, the administrator notices very poor performance and elevated disk latency across the server. Users report slow application response times. The array status shows a rebuild is in progress. What is the BEST next step?
