NEW QUESTION # 126
A user is asking the systems administrator for assistance with writing a script to verify whether a file exists.
Given the following:

Which of the following commands should replace the <CONDITIONAL> string?

  • A. if [ -f "$filename" ] then
  • B. if [ -f "$filename" ]; then
  • C. if [ -d "$filename" ]; then
  • D. if [ -f "$filename" ]; while

Answer: B

Explanation:
The command if [ -f "$filename" ]; then checks if the variable $filename refers to a regular file that exists.
The -f option is used to test for files. If the condition is true, the commands after then are executed. This is the correct way to replace the <CONDITIONAL> string. The other options are incorrect because they either use the wrong option (-d tests for directories), the wrong syntax (missing a semicolon after the condition), or the wrong keyword (while is used for loops, not conditions).

NEW QUESTION # 127
A Linux administrator cloned an existing Linux server and built a new server from that clone. The administrator encountered the following error after booting the cloned server:

The administrator performed the commands listed below to further troubleshoot and mount the missing filesystem:

Which of the following should administrator use to resolve the device mismatch issue and mount the disk?

  • A. mount disk by device-id
  • B. fsck -A
  • C. mount disk by-label
  • D. mount disk by-blkid

Answer: A

Explanation:
The administrator should use the command mount disk by device-id to resolve the device mismatch issue and mount the disk. The issue is caused by the cloned server having a different device name for the disk than the original server. The output of blkid shows that the disk has the device name /dev/sdb1 on the cloned server, but the output of cat /etc/fstab shows that the disk is expected to have the device name /dev/sda1. The command mount disk by device-id will mount the disk by using its unique identifier (UUID) instead of its device name. The UUID can be obtained from the output of blkid or lsblk -f. The command will mount the disk to the specified mount point (/data) and resolve the issue.


NEW QUESTION # 128
A systems administrator suspects a process with a PID of 2864 is consuming resources at an alarming rate. The administrator uses the command renice -n -5 -p2864, but it does not solve the issue. Which of the following commands should the administrator execute to correct the issue?

  • A. renice -n -10 -p 2864
  • B. renice -n 10 -p 2864
  • C. nice -n -5 -p 2864
  • D. nice -n 5 -p 2864

Answer: B

Explanation:
A higher value of priority actually makes the process lower priority; it means the process demands fewer system resources (and therefore is a "nicer" process). A lower priority value means the process demands more resources, possibly denying those resources to processes that are "nicer".
Range is - 20 to 19
-20 is highest priority
19 is lowest priority


NEW QUESTION # 129
A systems engineer deploys a new application server, but the server cannot communicate with the back-end database hostname. The engineer confirms that the application server can ping the database server's IP address. Which of the following is the most likely cause of the issue?

  • A. Incorrect DNS servers
  • B. Missing route configuration
  • C. Unreachable default gateway
  • D. Misconfigured subnet mask

Answer: A

Explanation:
If the application server can ping the database server by its IP address but not by its hostname, it indicates a DNS resolution issue. The most likely cause is incorrect DNS server configuration. The engineer should verify the DNS settings in /etc/resolv.conf or the network configuration.
