CompTIA CompTIA Certifications SK0-005 Questions & Answers

• Question 221:

  A server administrator has configured a web server. Which of the following does the administrator need to install to make the website trusted?

  A. PKI

  B. SSL

  C. LDAP

  D. DNS

  Correct Answer: B

• Question 222:

  A server that recently received hardware upgrades has begun to experience random BSOD conditions. Which of the following are likely causes of the issue? (Choose two.)

  A. Faulty memory

  B. Data partition error

  C. Incorrectly seated memory

  D. Incompatible disk speed

  E. Uninitialized disk

  F. Overallocated memory

  Correct Answer: AC

  Faulty memory and incorrectly seated memory are likely causes of the random BSOD conditions on the server. Memory is one of the most common hardware components that can cause BSOD (Blue Screen of Death) errors on Windows systems. BSOD errors occur when the system encounters a fatal error that prevents it from continuing to operate normally. Memory errors can be caused by faulty or incompatible memory modules that have physical defects or manufacturing flaws. Memory errors can also be caused by incorrectly seated memory modules that are not properly inserted or locked into the memory slots on the motherboard. This can result in loose or poor connections between the memory modules and the motherboard.

• Question 223:

  Which of the following will correctly map a script to a home directory for a user based on username?

  A. \\server\users$\username

  B. \\server\%username%

  C. \\server\FirstInitialLastName

  D. \\server\$username$

  Correct Answer: B

  The administrator should use \server%username% to correctly map a script to a home directory for a user based on username. %username% is an environment variable that represents the current user's name on a Windows system. By using

  this variable in the path of the script, the administrator can dynamically map the script to the user's home directory on the server. For example, if the user's name is John, the script will be mapped to \server\John.

• Question 224:

  Which of the following tools will analyze network logs in real time to report on suspicious log events?

  A. Syslog

  B. DLP

  C. SIEM

  D. HIPS

  Correct Answer: C

  SIEM is the tool that will analyze network logs in real time to report on suspicious log events. SIEM stands for Security Information and Event Management, which is a software solution that collects, analyzes, and correlates log data from various sources, such as servers, firewalls, routers, antivirus software, etc. SIEM can detect anomalies, patterns, trends, and threats in the log data and generate alerts or reports for security monitoring and incident response. SIEM can also provide historical analysis and compliance reporting for audit purposes.

• Question 225:

  Which of the following is the MOST appropriate scripting language to use for a logon script for a Linux box?

  A. VBS

  B. Shell

  C. Java

  D. PowerShell

  E. Batch

  Correct Answer: B

  Shell is the most appropriate scripting language to use for a logon script for a Linux box. Shell is a generic term for a command-line interpreter that allows users to interact with the operating system by typing commands and executing scripts. Shell scripts are files that contain a series of commands and instructions that can be executed by a shell. Shell scripts are commonly used for automating tasks, such as logon scripts that run when a user logs on to a system. There are different types of shells available for Linux systems, such as Bash, Ksh, Zsh, etc., but they all share a similar syntax and functionality.

• Question 226:

  Which of the following is an example of load balancing?

  A. Round robin

  B. Active-active

  C. Active-passive

  D. Failover

  Correct Answer: A

  Round robin is an example of load balancing. Load balancing is the method of distributing network traffic equally across a pool of resources that support an application. Load balancing improves application availability, scalability, security, and performance by preventing any single resource from being overloaded or unavailable. Round robin is a simple load balancing algorithm that assigns each incoming request to the next available resource in a circular order. For example, if there are three servers (A, B, C) in a load balancer pool, round robin will send the first request to server A, the second request to server B, the third request to server C, the fourth request to server A again, and so on.

• Question 227:

  A server administrator is using remote access to update a server. The administrator notices numerous error messages when using YUM to update the applications on a server. Which of the following should the administrator check FIRST?

  A. Network connectivity on the server

  B. LVM status on the server

  C. Disk space in the /var directory

  D. YUM dependencies

  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.

• Question 228:

  A technician is configuring a server that requires secure remote access. Which of the following ports should the technician use?

  A. 21

  B. 22

  C. 23

  D. 443

  Correct Answer: B

  The technician should use port 22 to configure a server that requires secure remote access. Port 22 is the default port for Secure Shell (SSH), which is a protocol that allows secure remote login and command execution over a network connection using a command-line interface (CLI). SSH encrypts both the authentication and data transmission between the client and the server, preventing eavesdropping, tampering, or spoofing. SSH can be used to perform various tasks on a server remotely, such as configuration, administration, maintenance, troubleshooting, etc.

• Question 229:

  A technician is installing a variety of servers in a rack. Which of the following is the BEST course of action for the technician to take while loading the rack?

  A. Alternate the direction of the airflow

  B. Install the heaviest server at the bottom of the rack

  C. Place a UPS at the top of the rack

  D. Leave 1U of space between each server

  Correct Answer: B

  The technician should install the heaviest server at the bottom of the rack to load the rack properly. Installing the heaviest server at the bottom of the rack helps to balance the weight distribution and prevent the rack from tipping over or collapsing. Installing the heaviest server at the bottom of the rack also makes it easier to access and service the server without lifting or moving it. Installing the heaviest server at any other position in the rack could create instability and safety hazards.

• Question 230:

  Which of the following is a method that is used to prevent motor vehicles from getting too close to building entrances and exits?

  A. Bollards

  B. Reflective glass

  C. Security guards

  D. Security cameras

  Correct Answer: A

  Bollards are an example of a method that is used to prevent motor vehicles from getting too close to building entrances and exits. Bollards are short, sturdy posts that are installed on sidewalks, parking lots, or roads to create physical barriers and control traffic flow. Bollards can be used to protect pedestrians, buildings, or other structures from vehicle collisions or attacks. Bollards can be made of various materials, such as metal, concrete, or plastic, and can be fixed, removable, or retractable.
