Question 1

IDS alerts indicate abnormal traffic patterns are coming from a specific server in a data center that hosts sensitive dat

a. Upon further investigation, the server administrator notices this server has been infected with a virus due to an exploit of a known vulnerability from its database software. Which of the following should the administrator perform after removing the virus to mitigate this issue from reoccurring and to maintain high availability? (Select three).



Answer : A, C, F

After removing the virus from the server, the administrator should perform the following actions to mitigate the issue from reoccurring and to maintain high availability:

Run a vulnerability scanner on the server to identify any other potential weaknesses or exposures that could be exploited by attackers.

Patch the vulnerability that allowed the virus to infect the server in the first place, using the latest updates from the database software vendor or a trusted source.

Update the antivirus software on the server to ensure it has the most recent virus definitions and can detect and prevent future infections. The other options are either unnecessary or counterproductive for this scenario. Repartitioning the hard drive, reformatting the OS, removing the database software, or air gapping the server from the network would cause downtime and data loss, while enabling a host firewall would not prevent a virus infection from within the network.Reference:CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.2: Given a scenario involving a security threat/vulnerability/risk, implement appropriate mitigation techniques.


Question 2

A user logs in to a Linux server and attempts to run the following command:

sudo emacs /root/file

However the user gets the following message:

User userid is not allowed to execute Temacs' on this server. Which of the following would BEST allow the user to find out which commands can be used?



Answer : B

This is the best command to find out which commands can be used by a user with sudo privileges because it lists the allowed and forbidden commands for a given user or role. The -l option stands for list, and the -U option specifies the user name. The output of this command will show what commands can be executed with sudo by that user on that server.Reference:https://www.sudo.ws/man/1.8.13/sudo.man.html


Question 3

An administrator is installing a new file server that has four drive bays available. Which of the following RAID types would provide the MOST storage as well as disk redundancy?



Answer : C

RAID 5 is a RAID level that provides striping with parity, which means that data is distributed across all disks with one disk storing parity information for error correction. RAID 5 can tolerate one disk failure without losing data. RAID 5 provides the most storage as well as disk redundancy out of the four RAID levels given, since it only uses one disk for parity and the rest for data. For example, if four 200GB drives are used in a RAID 5 array, the total storage capacity would be 600GB (200GB x 3), while in RAID 0 it would be 800GB (200GB x 4), in RAID 1 it would be 200GB (200GB x 1), and in RAID 10 it would be 400GB (200GB x 2).Reference:https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_5


Question 4

A systems administrator notices the fans are running at full speed in a newly upgraded server. Which of the following should be done to address this issue?



Answer : D

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:If the fans are running at full speed, it may indicate that the CPU or system temperature is too high. This is often caused by a poorly attached or improperly seated heat sink, which prevents efficient heat dissipation. Reattaching the heat sink with proper thermal paste resolves the issue.

A . Replace the PSU:Not relevant to temperature control.

B . Reseat the video card:Would not affect fan speed unless a GPU temperature issue exists, which is not stated here.

C . Reseat the RAM:Unrelated to fan operation.


Question 5

A server administrator is deploying a new server that has two hard drives on which to install the OS. Which of the following RAID configurations should be used to provide redundancy for the OS?



Answer : B

RAID 1 (mirroring) is a RAID configuration that should be used to provide redundancy for the OS on a server that has two hard drives on which to install the OS. RAID 1 (mirroring) is a configuration that duplicates data across two or more drives. It provides fault tolerance and improves read performance, but reduces storage capacity by half. If one drive fails in RAID 1, the other drive can continue to operate without data loss or system downtime. RAID 0 (striping) is a configuration that splits data across two or more drives without parity or redundancy. It improves performance but offers no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 5 (striping with parity) is a configuration that stripes data across three or more drives with parity information. It provides fault tolerance and improves performance, but reduces storage capacity by one drive's worth of space. RAID 5 can tolerate one drive failure without data loss, but not two ormore. RAID 6 (striping with double parity) is a configuration that stripes data across four or more drives with double parity information. It provides fault tolerance and improves performance, but reduces storage capacity by two drives' worth of space. RAID 6 can tolerate two drive failures without data loss, but not three or more.Reference:https://www.howtogeek.com/199068/how-to-upgrade-your-existing-hard-drive-in-under-an-hour/


Question 6

A server technician has been asked to upload a few files from the internal web server to the internal FTP server. The technician logs in to the web server using PuTTY, but the connection to the FTP server fails. However, the FTP connection from the technician's workstation is sucessful. To troubleshoot the issue, the technician executes the following command on both the web server and the workstation:

ping ftp.acme.local

The IP address in the command output is different on each machine. Which of the following is the MOST likely reason for the connection failure?



Answer : D

A misconfigured hosts file can cause name resolution issues on a server. A hosts file is a text file that maps hostnames to IP addresses on a local system. It can be used to override DNS settings or provide custom name resolution for testing purposes. However, if the hosts file contains incorrect or outdated entries, it can prevent the system from resolving hostnames properly and cause connectivity problems. To fix this issue, the administrator should check and edit the hosts file accordingly.


Question 7

A server administrator is tasked with ensuring that information stored on company database systems is secure from bad actors. Which of the following security practices would accomplish this task?



Answer : A
