Correct Answer: C

A login script is a file that contains commands or instructions that are executed when a user logs into a system or network. A login script can be used to map a network drive to a user profile, which means that the user will have access to a shared folder or resource on another computer or server. A login script can be written in various languages, such as batch, PowerShell, or VBScript, and can be assigned to a user or a group using tools such as Group Policy or Active Directory . A system service (A) is a program that runs in the background and performs tasks that are essential for the operation of the system, such as security, networking, or hardware management. A system service does not map a network drive to a user profile. A network service (B) is a program that provides functionality or resources to other programs or devices over a network, such as file sharing, printing, or web hosting. A network service does not map a network drive to a user profile. A kickstart script (D) is a file that contains configuration settings and commands for automated installation of Linux operating systems. A kickstart script does not map a network drive to a user profile.

Correct Answer: B

A purple screen with white letters on an ESX server indicates a kernel panic, which is a fatal error that causes the system to crash and stop functioning3. The first troubleshooting step that an administrator should perform is to review the log files, which may contain information about the cause of the error, such as hardware failures, software bugs, or configuration issues4. Checking the power supplies (A) may not be relevant, as the system is still displaying a screen. Reinstalling the ESX server ?or reseating the processors (D) are drastic measures that may result in data loss or further damage, and should only be attempted after ruling out other possible causes.

Correct Answer: B

The /etc/fstab file contains the information about the file systems that are mounted automatically at boot time or on demand. The entry nfsserver:/home /home nfs defaults 0 0 indicates that the /home directory on the local server is mounted from the /home directory on a remote server called nfsserver using the NFS protocol. However, the df -h /home command shows that the /home directory is actually mounted from a local partition /dev/sda2, which may not contain the user's files. This means that the NFS mount failed or was overridden by another mount. To resolve the issue, the technician should attempt to unmount the local partition using umount nfsserver:/home, which will detach the /home directory from / dev/sda2. Then, the technician should try to mount the NFS share again using mount /home, which will attach the /home directory to nfsserver:/home according to the /etc/fstab entry12. Creating a new directory (A) or removing an existing one ?would not help, as they would not affect the mount point. Mounting /home (D) without unmounting it first would not work, as it would result in an error that the mount point is busy3.

Correct Answer: A

The connection type that the server administrator is using to access the server remotely is out-of-band management. Out-of-band management is a method of accessing and controlling a server through a dedicated network interface or port that is separate from the regular data network. Out-of-band management allows administrators to perform tasks such as rebooting, configuring, troubleshooting, or updating a server even if the server is offline or unresponsive through the regular network. Out-of-band management can use protocols such as IPMI, iLO, DRAC, or BMC. Reference: https://www.ibm.com/cloud/learn/out-of-band-management

Correct Answer: B

Correct Answer: C

This is the most likely cause of the issue because firewall rules can block or allow traffic based on source, destination, port, protocol, or other criteria. If the firewall rules are not configured properly, they can prevent remote users from accessing the cloud application server, while allowing on-site users to access it.

Correct Answer: C

The administrator should check disk space in the /var directory first when using YUM to update applications on a server. YUM stands for Yellowdog Updater Modified, which is a software package manager for Linux systems that use RPM (Red Hat Package Manager) packages. YUM downloads and installs packages from online repositories and resolves dependencies automatically. YUM stores its cache files in the /var/cache/yum directory by default. These cache files include metadata and package data for each repository that YUM uses. If there is not enough disk space in the /var directory, YUM may fail to update applications and generate error messages.

Correct Answer: A

Install Latest Patches Don't forget about the applications that may be running on the server. Applications can also be attacked by hackers. That's why software vendors are also periodically issuing security updates. As security issues are reported, they respond by fixing the software. For Windows applications, these updates can accompany the operating system updates if you choose to enable them.

Other applications may be more of a challenge, but it's hard to find vendors today that don't either automatically send and install the updates or, at the very least, notify you that one is available.
