최신 Linux+ XK0-006 무료샘플문제 (Q63-Q68):
질문 # 63
Which of the following utilities can securely delete a Linux directory from a filesystem and ensure it cannot be recovered?
- A. shred
- B. unlink
- C. dd
- D. rm
정답:A
설명:
This utility securely overwrites data on disk to prevent recovery, making it suitable for securely deleting data from a filesystem in accordance with security best practices.
질문 # 64
A systems administrator is configuring new Linux systems and needs to enable passwordless authentication between two of the servers. Which of the following commands should the administrator use?
- A. ssh-add -t rsa && scp -rp ~/.ssh john@server2
- B. ssh-agent -i rsa && ssh-copy-id ~/.ssh/key john@server2
- C. ssh-keygen -t rsa && ssh-copy-id -i ~/.ssh/id_rsa.pub john@server2
- D. ssh-keyscan -t rsa && ssh-copy-id john@server2 -i ~/.ssh/key
정답:C
설명:
Comprehensive and Detailed 250 to 350 words of Explanation From Linux+ V8 documents:
Passwordless authentication using SSH key pairs is a foundational security practice covered in the Security domain of CompTIA Linux+ V8. It allows administrators to securely authenticate between systems without transmitting passwords over the network, significantly reducing the risk of credential compromise.
The correct approach involves two essential steps: generating an SSH key pair and installing the public key on the remote system. Option A correctly performs both steps using best-practice commands.
The command ssh-keygen -t rsa generates an RSA public/private key pair in the user's ~/.ssh/ directory. The private key (id_rsa) remains securely on the local system, while the public key (id_rsa.pub) is intended to be shared. The second part of the command, ssh-copy-id -i ~/.ssh/id_rsa.pub john@server2, securely copies the public key to the remote server's ~/.ssh/authorized_keys file. This enables key-based authentication for the specified user.
The other options are incorrect or incomplete. Option B uses ssh-keyscan, which is intended for collecting host keys to populate known_hosts, not for user authentication. Option C misuses ssh-agent, which manages keys already generated and does not create or install them. Option D is insecure and incorrect because copying the entire .ssh directory risks exposing private keys and violates security best practices.
Linux+ V8 documentation emphasizes the use of ssh-keygen and ssh-copy-id as the standard, secure method for configuring passwordless SSH access. This approach ensures proper permissions, correct key placement, and minimal risk.
질문 # 65
A systems administrator is helping to secure a new web application. During the tests, the administrator obtains the following output to validate the application:

Which of the following explains the validation results?
- A. The certificate was not signed by trusted authority, which was forcefully ignored during the tests.
- B. The certificate was only issued for one month, is already expired, and needs to be replaced
- C. The certificate uses an outdated algorithm and should be replaced with a more secure one.
- D. The certificate is a wildcard certificate that is highly insecure and should never be used.
정답:A
설명:
The validation output indicates that the certificate chain could not be verified because the local system does not trust the issuing certificate authority, and the connection proceeded anyway by ignoring the verification failure during testing.
질문 # 66
An administrator needs to append the output of a Linux command to an existing file for later analysis. Which of the following command-line strings should the administrator use?
- A. ls >> file.txt
- B. echo ls | sed -i file.txt
- C. tcc ls > awk file.txt
- D. cat ls > file.txt
정답:A
설명:
This command uses output redirection in append mode, adding the command's output to the end of the existing file without overwriting its current contents.
질문 # 67
An administrator is trying to terminate a process that is not responding. Which of the following commands should the administrator use in order to force the termination of the process?
- A. kill -9 PID
- B. kill -1 PID
- C. kill PID
- D. kill -15 PID
정답:A
설명:
The kill command is used to send signals to processes. The -9 option sends the SIGKILL signal, which immediately terminates the process and cannot be caught or ignored by the process. This is used as a last resort when a process is not responding to the default (SIGTERM, -15) or other signals. The SIGKILL signal guarantees termination.
