comptia server+ practice test Practice Exam 2025: Latest Questions

A technician is installing a new rackmount server in a data center. Which action is the BEST practice to reduce the risk of injury and equipment damage during installation?

An administrator wants to ensure a server can continue operating if one power supply fails. Which feature should be implemented?

A server’s iDRAC/iLO management interface is reachable on the production network and uses default credentials. Which action is the MOST appropriate immediate remediation?

A server’s NIC link light is off after a planned move to a new rack. The switch port shows no link. Which is the FIRST troubleshooting step?

A company needs to run multiple isolated workloads on a single physical server. The workloads require different operating systems, and the company wants the ability to move workloads between hosts with minimal downtime. Which solution BEST meets these requirements?

An administrator must ensure that if the primary site is lost, business-critical services can be restored at a secondary site within 2 hours, with no more than 15 minutes of data loss. Which pairing BEST represents these requirements?

A file server’s RAID controller reports a degraded array after a disk failure. The array supports hot-swap. Which action should the administrator take to minimize downtime while restoring redundancy?

Users report that an application hosted on a server becomes slow at random times. Monitoring shows CPU utilization is low, but disk latency spikes and the disk queue length is consistently high during slowdowns. Which is the MOST likely bottleneck?

A security audit requires that backups stored offsite remain confidential even if the storage provider is compromised, and that only specific servers can decrypt the data. Which approach BEST meets the requirement?

A virtualized database server experiences brief freezes. The hypervisor logs show frequent VM pauses due to memory reclamation, and the host reports swapping activity. Other VMs on the same host appear unaffected. Which change is MOST likely to resolve the issue without adding new hardware?

A technician installs additional RAM in a rack server. On the next boot, the system beeps and reports a memory configuration error. The new DIMMs are the same capacity as existing modules but were installed in random slots. What is the MOST likely fix?

A server administrator wants to reduce the chance that a user can recover sensitive data from a decommissioned storage array before it is returned to the vendor. Which action BEST addresses this requirement?

A technician needs to verify whether a server’s management NIC is reachable on the network before attempting remote KVM access. Which tool is the BEST first step?

A company is implementing a backup strategy for a file server. Management requires backups that can be quickly restored from disk while also maintaining an off-site copy in case of a site outage. Which approach BEST meets these requirements?

A technician replaces a failed drive in a RAID 6 array. The controller marks the new drive as 'Unconfigured Good' but the array does not begin rebuilding. What is the MOST likely next step?

After a power event, a server boots but services are unreachable. The OS reports the NIC is up, but users cannot connect. The switch shows the port is err-disabled due to a security violation. Which configuration is MOST likely responsible?

An administrator needs to ensure only approved workloads can run on a virtualization host and wants to reduce risk from malicious or unsigned images. Which control BEST supports this goal?

A database server experiences intermittent performance degradation. Monitoring shows high disk latency and a queue depth that spikes during peak hours, but CPU and memory are within normal ranges. Which action is MOST likely to improve performance?

A company requires that administrators access servers through a single controlled entry point where sessions are logged and privileged commands can be audited. The servers are distributed across multiple network segments. Which solution BEST meets this requirement?

A virtualization cluster must tolerate the loss of any one host without downtime. Each host has two 10GbE NICs available for VM traffic and storage traffic. The storage platform uses network-based storage. Which design BEST supports high availability and reduces single points of failure?

A server has multiple identical hot-swappable power supplies installed. During routine maintenance, an administrator wants to confirm the power configuration provides continued operation if a PSU fails. Which configuration BEST describes this capability?

A technician installs a new hardware RAID controller and wants to ensure the OS can boot even if a single drive fails. Which RAID level is the BEST choice?

An administrator must allow a vendor to access a server for troubleshooting, but access should automatically expire after 24 hours and should not require sharing permanent admin credentials. Which solution BEST meets these requirements?

After a scheduled reboot, a virtualized application server comes online but users report intermittent timeouts. The hypervisor dashboard shows the VM's CPU usage is low, but disk latency is consistently high across multiple VMs on the same datastore. Which action is the BEST next step?

A company wants to improve recoverability for a critical file server. They need the ability to restore individual files from a known-good point without taking the entire server offline, and they also want protection against ransomware encrypting the production share. Which approach BEST meets these goals?
