CompTIA Server+ Certification Exam Sample Questions (Q49-Q54):

NEW QUESTION # 49
An administrator is asked to harden a Linux server after installing the OS. Which of the following should the administrator do FIRST?

A. Set up a personal firewall.
B. Install the latest OS patches.
C. Disable the HIDS.
D. Enable WOL.

Answer: B

NEW QUESTION # 50
A datacenter in a remote location lost power. The power has since been restored, but one ol the servers has not come back online. After some investigation, the server is found to still be powered off. Which of the following is the BEST method to power on the server remotely?

A. RDP
B. Out-of-band console
C. Crash cart
D. IP KVM

Answer: B

Explanation:
Explanation
Out-of-band console is a tool that can be used to command a remote shutdown of a physical Linux server.
Out-of-band console is a method of accessing a server's console through a dedicated management port or device that does not rely on the server's operating system or network connection. Out-of-band console can be used to power cycle, reboot, update firmware, monitor performance, and perform other tasks remotely even if the server is unresponsive or offline. Crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be used to troubleshoot a server on-site, but it requires physical access to the server. IP KVM (Internet Protocol Keyboard Video Mouse) switch is a hardware device that allows remote access to multiple servers using a web browser or a client software, but it requires network connectivity and may not work if the SSH connection is lost. RDP (Remote Desktop Protocol) is a protocol that allows remote access to a Windows server's graphical user interface, but it does not work on Linux servers and requires network connectivity.

NEW QUESTION # 51
An administrator discovers a Bash script file has the following permissions set in octal notation;
777
Which of the following is the MOST appropriate command to ensure only the root user can modify and execute the script?

A. chmod u=rwx
B. chmod go-rw>:
C. chmod u+wx
D. chmod g-rwx

Answer: B

Explanation:
Explanation
chmod is a command-line tool that changes the permissions of files and directories in Linux and Unix systems.
chmod go-rwx means to remove read, write, and execute permissions for group and other users from a file or directory. This can ensure only the root user can modify and execute the script, since root user has full access to all files and directories regardless of their permissions. References: https://linux.die.net/man/1/chmod

NEW QUESTION # 52
A server administrator is installing a new server that uses 40G0 network connectivity. The administrator needs to find the proper cables to connect the server to the switch. Which of the following connectors should the administrator use?

A. GBIC
B. QSFP+
C. SFP+
D. SFP

Answer: B

Explanation:
QSFP+ is a type of connector that should be used to connect a server to a switch that uses 40G network connectivity. QSFP+ (Quad Small Form-factor Pluggable Plus) is a compact, hot-pluggable transceiver module that supports data rates up to 40 Gbps. QSFP+ modules can be used for various network protocols and media types, such as Ethernet, Fibre Channel, InfiniBand, or optical fiber. QSFP+ modules have a 38-pin edge connector and can be inserted into a QSFP+ port on a switch or a server. SFP+ (Small Form-factor Pluggable Plus) is a type of connector that supports data rates up to 10 Gbps, but not 40 Gbps. SFP+ modules have a 20-pin edge connector and can be inserted into an SFP+ port on a switch or a server. GBIC (Gigabit Interface Converter) is an older type of connector that supports data rates up to 1 Gbps, but not 40 Gbps.
GBIC modules have an SC duplex connector and can be inserted into a GBIC port on a switch or a server.
SFP (Small Form-factor Pluggable) is another older type of connector that supports data rates up to 1 Gbps or
4 Gbps, but not 40 Gbps. SFP modules have an LC duplex connector and can be inserted into an SFP port on a switch or a server.

NEW QUESTION # 53
A technician retailed a new 4TB hard drive in a Windows server. Which of the following should the technician perform FIRST to provision the new drive?

A. Partition the drive using OPT.
B. Configure the drive as a base disk.
C. Partition the drive using MBR.
D. Configure the drive as a dynamic disk.

Answer: A

Explanation:
Explanation
GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. MBR (Master Boot Record) is an older partitioning scheme that has limitations on the size and number of partitions (up to 4 primary partitions or 3 primary and 1 extended partition per drive). To provision a new 4 TB drive, the technician should partition it using GPT. Verified References: [GPT], [MBR]
