A Linux server was recently updated. The server now stops during the boot process with a blank screen and an fs> prompt. Which of the following is the most likely cause of this issue?
Answer : B
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:
The fs> prompt typically indicates that the Unified Extensible Firmware Interface (UEFI) has entered the EFI shell due to a failure in locating the bootloader or a critical Linux boot file. This often occurs after an update where boot files are moved, renamed, or deleted. To resolve:
Verify the bootloader configuration (e.g., GRUB) and ensure the correct partition is set for booting.
Recreate or repair the bootloader files if necessary.
Ensure the boot sequence in UEFI settings points to the correct disk and partition.
Other options:
A . USB flash drive booting: Unlikely unless the boot order was unintentionally altered.
C . BIOS not finding a bootable hard disk: Would generally result in a different error message.
D . BIOS firmware upgrade: Not typically required for this specific issue.
The internal IT department policy for monitoring server health requires that evidence of server reboots be collected and reviewed on a regular basis. Which of the following should be monitored to best provide this evidence?
Answer : D
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:
Event logs are 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.
When a user plugs a USB drive into a workstation and attempts to transfer a file from the server, an error appears that indicates the file cannot be copied. However, the user can copy or create new files from the local workstation. Which of the following is part of this security strategy?
Answer : D
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:
Data Loss Prevention (DLP) policies are designed to prevent sensitive data from being copied, moved, or accessed in unauthorized ways. In this scenario, the DLP system is likely configured to block file transfers from the server to external storage devices, such as USB drives, while still allowing local file creation or movement.
HIDS (Host-Based Intrusion Detection System): Monitors system activities for malicious behavior but does not block file transfers.
SIEM (Security Information and Event Management): Provides centralized monitoring and analysis of security events but does not directly enforce file transfer restrictions.
ACL (Access Control List): Manages permissions but does not control data transfer policies.
An administrator is upgrading a group of legacy blade servers to the latest version of the hypervisor. After restarting the server, the upgrade is interrupted. The hypervisor is not available, and the update is not successful. Which of the following should the administrator do next to accomplish this upgrade?
Answer : B
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:
Firmware incompatibility is a common issue when upgrading hypervisors, especially on legacy hardware. Upgrading the firmware ensures that the hardware is compatible with the new hypervisor version. This includes updating BIOS, RAID controllers, and network adapters to the latest supported versions.
A . New installation: Risks data loss and is unnecessary if the issue is firmware-related.
C . Increasing RAM: May enhance performance but does not resolve compatibility issues.
D . Hardware upgrade: A last resort if firmware updates do not resolve the problem.
A server administrator set up a monitoring application on various servers to keep track of CPU usage, memory consumption, and disk space utilization. Which of the following should be configured on the application so it can send email alerts about a specific issue?
Answer : B
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:
Configuring thresholds allows the monitoring application to define limits (e.g., CPU usage > 90%, disk space < 10%) that trigger email alerts when exceeded. This proactive measure helps administrators address issues before they escalate.
Event logs: Provide historical data but do not send alerts.
Disk quotas: Restrict user disk usage but are unrelated to alerts.
Uptime lengths: Measure server runtime but do not trigger alerts.
