This area requires that you have knowledge of how to manage tuning profiles, preserve system journals, securely transfer files between systems, and adjust process scheduling. You will be able to answer the questions related to the interruption of the boot process in order to gain access to a system, identification of the memory/CPU intensive processes and killing of these processes, as well as adjustment of the process scheduling. This domain also evaluates your knowledge of how to shut down, boot, and reboot a system normally.
- Deploying, Configuring, and Maintaining Systems
For this subject, you need to have skills in scheduling tasks using cron and at, configuring the time service clients, working with package module streams, as well as starting and stopping services and configuring them to start automatically at boot. It is also essential to know how to modify the system bootloader and configure systems to boot into a specific target automatically. Your ability to update and install software packages from a remote repository, Red Hat Network, or from the local file system will also define your overall result.
- Understanding and Using Essential Tools
In this domain, it is important to know how to use regular and grep expressions to analyze text, create soft and hard links, use input-output redirection, and log in the users and switch them in multiuser targets. It also includes your expertise in accessing the remote systems with the use of SSH and shell prompt and issue commands with correct syntax.

Answer:
Explanation:
# chkconfig autofs on
# cd /etc/
# vim /etc/auto.master
/rhome /etc/auto.ldap
# cp auto.misc auto.ldap
# vim auto.ladp
ldapuser40 -rw,soft,intr 172.24.40.10:/rhome/ldapuser40
* -rw,soft,intr 172.16.40.10:/rhome/&
# service autofs stop
# server autofs start
# showmount -e 172.24.40.10
# su - ladpuser40
NEW QUESTION 35

Configure autofs.
Configure the autofs automatically mount to the home directory of LDAP, as required:
server.domain11.example.com use NFS to share the home to your system. This file system contains a pre configured home directory of user ldapuserX.
Home directory of ldapuserX is:
server.domain11.example.com /home/guests/ldapuser
Home directory of ldapuserX should automatically mount to the ldapuserX of the local /home/guests Home directory's write permissions must be available for users ldapuser1's password is password
Answer:
Explanation:
See explanation below.
Explanation/Reference:
Explanation: yum install -y autofs
mkdir /home/rehome
/etc/auto.master
/home/rehome/etc/auto.ldap
Keep then exit
cp /etc/auto.misc /etc/auto.ldap
/etc/auto.ldap
ldapuserX -fstype=nfs,rw server.domain11.example.com:/home/guests/
Keep then exit
systemctl start autofs
systemctl enable autofs
su - ldapuserX// test
If the above solutions cannot create files or the command prompt is -bash-4.2$, it maybe exist multi-level directory, this needs to change the server.domain11.example.com:/home/guests/ to server.domain11.example.com:/home/guests/ldapuserX. What is multi-level directory? It means there is a directory of ldapuserX under the /home/guests/ldapuserX in the questions. This directory is the real directory.
