NEW QUESTION # 172
A Linux administrator is troubleshooting SSH connection issues from one of the workstations.
When users attempt to log in from the workstation to a server with the IP address 104.21.75.76, they receive the following message:

The administrator reviews the information below:


Which of the following is causing the connectivity issue?

  • A. The sshd service is disabled.
  • B. The server's firewall is preventing connections from being made.
  • C. The server has an incorrect default gateway configuration.
  • D. The workstation has the wrong IP settings.

Answer: B

Explanation:
The server's firewall is preventing connections from being made, which is causing the connectivity issue. The output of iptables -L -n shows that the firewall is blocking all incoming traffic on port 22, which is the default port for SSH. The output of ssh -v [email protected] shows that the connection is refused by the server. To resolve the issue, the administrator needs to allow port 22 on the firewall. The other options are incorrect because they are not supported by the outputs. The workstation has the correct IP settings, as shown by the output of ip addr show. The sshd service is enabled and running, as shown by the output of systemct1 status sshd. The server has the correct default gateway configuration, as shown by the output of ip route show.

NEW QUESTION # 173
A Linux administrator is trying to remove the ACL from the file /home/user/data. txt but receives the following error message:

Given the following analysis:

Which of the following is causing the error message?

  • A. File attributes are preventing file modification.
  • B. The administrator is not using a highly privileged account.
  • C. SELinux file context is denying the ACL changes.
  • D. The filesystem is mounted with the wrong options.

Answer: A

Explanation:
Explanation
File attributes are preventing file modification, which is causing the error message. The output of lsattr
/home/user/data.txt shows that the file has the immutable attribute (i) set, which means that the file cannot be changed, deleted, or renamed. The command setfacl -b /home/user/data.txt tries to remove the ACL from the file, but fails because of the immutable attribute. The administrator needs to remove the immutable attribute first by using the command chattr -i /home/user/data.txt and then try to remove the ACL again. The other options are incorrect because they are not supported by the outputs. The administrator is using a highly privileged account, as shown by the # prompt. The filesystem is mounted with the correct options, as shown by the output of mount | grep /home. SELinux file context is not denying the ACL changes, as shown by the output of ls -Z /home/user/data.txt.

Answer: C


NEW QUESTION # 175
Which of the following is the best tool for dynamic tuning of kernel parameters?

  • A. turbostat
  • B. tune2fs
  • C. tuned-adm
  • D. tuned

Answer: D

Explanation:
The tuned application is the best tool for dynamic tuning of kernel parameters, as it monitors the system and optimizes the performance under different workloads. It provides a number of predefined profiles for typical use cases, such as power saving, low latency, high throughput, virtual machine performance, and so on. It also allows users to create, modify, and delete profiles, and to switch between them on the fly. The tuned application uses the sysctl command and the configuration files in the /etc/sysctl.d/ directory to adjust the kernel parameters at runtime.
