A Linux server was recently updated. Now, the server 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?
A. The system is booting to a USB flash drive.
B. The UEFI boot was interrupted by a missing Linux boot file.
C. The BIOS could not find a bootable hard disk.
D. The BIOS firmware needs to be upgraded.
Show Answer
Correct Answer: B
Explanation: The `fs>` prompt indicates the system has dropped into the UEFI shell. This most likely means UEFI could not locate or load the Linux EFI boot file, possibly after the update.
Question 112
Which of the following script types uses commands that start with Set-?
A. Batch
B. Bash
C. PowerShell
D. JavaScript
Show Answer
Correct Answer: C
Explanation: PowerShell uses a verb-noun command naming convention, and many commands that set or change values begin with “Set-,” such as Set-Variable and Set-Service.
Question 113
An administrator is helping to replicate a large amount of data between two Windows servers. The administrator is unsure how much data has already been transferred. Which of the following will BEST ensure all the data is copied consistently?
A. rsync
B. copy
C. scp
D. robocopy
Show Answer
Correct Answer: D
Explanation: Robocopy is designed for robust file replication on Windows. It supports restarting interrupted transfers, retries, and logging, making it the best choice for reliably copying a large dataset.
Question 114
A technician is able to copy a file to a temporary folder on another partition but is unable to copy it to a network share or a USB flash drive. Which of the following is MOST likely preventing the file from being copied to certain locations?
A. An ACL
B. Antivirus
C. DLP
D. A firewall
Show Answer
Correct Answer: C
Explanation: DLP (Data Loss Prevention) controls can restrict copying files to external destinations such as USB drives and network shares while allowing movement within local partitions.
Question 115
A server administrator needs to implement load balancing without purchasing any new hardware or implementing any new software. Which of the following will the administrator MOST likely implement?
A. Round robin
B. Link aggregation
C. Most recently used
D. Heartbeat
Show Answer
Correct Answer: A
Explanation: Round robin can distribute requests across existing servers using a scheduling method, without requiring a dedicated load-balancing appliance or new software. Link aggregation combines network links on a host or switch; it is not the best fit for balancing requests across servers.
Question 116
A technician installed a kernel upgrade to a Linux server. The server now crashes regularly. Which of the following is the MOST likely cause?
A. Necessary dependencies were installed for multiple architectures.
B. There is not enough hard drive space.
C. The server is infected with a virus.
D. Some modules are not compatible.
Show Answer
Correct Answer: D
Explanation: A kernel upgrade can make existing kernel modules incompatible. Incompatible modules may cause instability or crashes, making this the most likely cause.
Question 117
A technician has been tasked to install a new CPU. Prior to the installation, the server must be configured. Which of the following should the technician update?
A. The RAID card
B. The BIOS
C. The backplane
D. The HBA
Show Answer
Correct Answer: B
Explanation: Update the BIOS (or UEFI firmware) to ensure it supports and can properly recognize the new CPU.
Question 118
A server administrator is connecting a Linux server to a storage array. The administrator wants to use a file-based storage protocol to store data on the server. Which of the following protocols will the administrator MOST likely use?
A. NFS
B. FCoE
C. iSCSI
D. CIFS
Show Answer
Correct Answer: A
Explanation: NFS is a file-based storage protocol commonly used by Linux servers to access shared files on a storage array. FCoE and iSCSI are block-based protocols, while CIFS/SMB is more commonly associated with Windows file sharing.
Question 119
Which of the following backup types resets the archive bit each time it is run?
A. Differential
B. Snapshot
C. Incremental
D. Synthetic full
Show Answer
Correct Answer: C
Explanation: An incremental backup resets the archive bit on files after backing them up, marking them as backed up. A differential backup leaves the bit set so later differential backups continue to include changes since the last full backup.
Question 120
A technician is creating a network share that will be used across both Unix and Windows clients at the same time. Users need read and write access to the files. Which of the following would be BEST for the technician to deploy?
A. iSCSI
B. CIFS
C. HTTPS
D. DAS
Show Answer
Correct Answer: B
Explanation: CIFS (the protocol associated with SMB) provides network file sharing with read/write access and is supported by Windows and Unix-like clients. iSCSI provides block-level storage, HTTPS is not a general shared-filesystem protocol, and DAS is directly attached storage.
