質問 # 48
A Linux engineer wants to give read-write-execute permissions for the cloud_users directory to user Oliver. Which of the following commands should the engineer use?
- A. setfacl -L Oliver
/cloud_users
- B. setfacl -x rwx
/cloud_users
- C. setfacl -m u:Oliver
/cloud_users
- D. setfacl -P rwx
/cloud_users
正解：C
解説：
The setfacl -m u:Oliver:rwx /cloud_users command modifies the ACL (Access Control List) for the directory cloud_users, granting the user Oliver read, write, and execute permissions. This is the correct syntax for assigning specific permissions to a user.

A junior administrator is trying to set up a passwordless SSH connection to one of the servers.
The administrator follows the instructions and puts the key in the authorized_key file at the server, but the administrator is still asked to provide a password during the connection.
Given the following output:
Which of the following commands would resolve the issue and allow an SSH connection to be established without a password?
- A. restorecon -rv .ssh/authorized_key
- B. mv .ssh/authorized_key .ssh/authorized_keys
- C. systemctl restart sshd.service
- D. chmod 600 mv .ssh/authorized_key
正解：B
解説：
The command mv .ssh/authorized_key .ssh/authorized_keys will resolve the issue and allow an SSH connection to be established without a password. The issue is caused by the incorrect file name of the authorized key file on the server. The file should be named authorized_keys, not authorized_key. The mv command will rename the file and fix the issue.
質問 # 50

質問 # 51
A Linux user reported the following error after trying to connect to the system remotely:
ssh: connect to host 10.0.1.10 port 22: Resource temporarily unavailable The Linux systems administrator executed the following commands in the Linux system while trying to diagnose this issue:
Which of the following commands will resolve this issue?
- A. firewall-cmd --zone=public --permanent --add-service=22
- B. firewall-cmd --zone=public --permanent --add-port=22/udp
- C. systemctl enable firewalld; systemctl restart firewalld
- D. firewall-cmd --zone=public --permanent --add-service=ssh
正解：D
解説：
Explanation
The firewall-cmd --zone=public --permanent --add-service=ssh command will resolve the issue by allowing SSH connections on port 22 in the public zone of the firewalld service. This command will add the ssh service to the permanent configuration of the public zone, which means it will persist after a reboot or a reload of the firewalld service. The firewall-cmd --zone=public --permanent --add-service=22 command is invalid, as 22 is not a valid service name. The systemctl enable firewalld; systemctl restart firewalld command will enable and restart the firewalld service, but it will not change the firewall rules. The firewall-cmd --zone=public
--permanent --add-port=22/udp command will allow UDP traffic on port 22 in the public zone, but SSH uses TCP, not UDP. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 18: Securing Linux Systems, page 543.
質問 # 52
A user is attempting to log in to a Linux server that has Kerberos SSO ena-bled. Which of the following commands should the user run to authenticate and then show the ticket grants? (Select TWO).
- A. kexec
- B. klist
- C. kioad
- D. pkexec
- E. kinit
- F. realm
正解：B、E
解説：
The following commands can help the user to authenticate and show the ticket grants using Kerberos SSO on a Linux server:
* kinit: This command obtains and caches an initial ticket-granting ticket (TGT) for the user from the Kerberos key distribution center (KDC). The user needs to enter their password or use a keytab file to authenticate1.
* klist: This command lists the cached tickets, including the TGT and any service tickets, for the user. It also shows the expiration time and flags for each ticket2.
For example, the user can run the following commands to log in and view their tickets:
$ kinit username@REALM
Password for username@REALM:
$ klist
Ticket cache: FILE:/tmp/krb5cc_1000
Default principal: username@REALM
Valid starting Expires Service principal
04/06/2023 16:06:59 04/07/2023 02:06:59 krbtgt/REALM@REALM
renew until 04/13/2023 16:06:59

* kinit(1) - Linux man page, section "Description".
* klist(1) - Linux man page, section "Description".
