NEW QUESTION # 881
A systems administrator is tasked with installing GRUB on the legacy MBR of the SATA hard drive. Which of the following commands will help the administrator accomplish this task?
  • A. grub-install /dev/sr0
  • B. grub-install /dev/hda
  • C. grub-install /dev/hd0,0
  • D. grub-install /dev/sda
Answer: D
Explanation:
The command that will help the administrator install GRUB on the legacy MBR of the SATA hard drive is grub-install /dev/sda. This command will install GRUB on the master boot record (MBR) of the first SATA disk (/dev/sda). The MBR is the first sector of a disk that contains boot code and a partition table. GRUB will overwrite the boot code and place its own code that can load GRUB modules and configuration files from a specific partition.

NEW QUESTION # 882
Joe, a user, is unable to log in to the Linux system. Given the following output:

Which of the following commands would resolve the issue?
  • A. pam_tally2 -u joe -r
  • B. chage -E 90 joe
  • C. usermod -s /bin/bash joe
  • D. passwd -u joe
Answer: A
Explanation:
The command pam_tally2 -u joe -r will resolve the issue of Joe being unable to log in to the Linux system.
The pam_tally2 command is a tool for managing the login counter for the PAM (Pluggable Authentication Modules) system. PAM is a framework for managing authentication and authorization on Linux systems.
PAM allows the administrator to define the rules and policies for accessing various system resources and services, such as login, sudo, ssh, or cron. PAM also supports different types of authentication methods, such as passwords, tokens, biometrics, or smart cards. PAM can be used to implement login restrictions, such as limiting the number of failed login attempts, locking the account after a certain number of failures, or enforcing a minimum or maximum time between login attempts. The pam_tally2 command can display, reset, or unlock the login counter for the users or hosts. The -u joe option specifies the user name that the command should apply to. The -r option resets the login counter for the user. The command pam_tally2 -u joe -r will reset the login counter for Joe, which will unlock his account and allow him to log in to the Linux system.
This will resolve the issue of Joe being unable to log in to the Linux system. This is the correct command to use to resolve the issue. The other options are incorrect because they either do not unlock the account (usermod -s /bin/bash joe or passwd -u joe) or do not affect the login counter (chage -E 90 joe).

  • A. No IP address is assigned to the interface.
  • B. The gateway is unreachable.
  • C. The network interface is disconnected.
  • D. A connection problem exists on the network interface.
Answer: D
Explanation:
The high number of errors and dropped packets in the output of the network interface counters indicate a connection problem on the network interface.
