• Question 341:

  A server technician notices a server is very low on disk space. Upon inspecting the disk utilization, the technician discovers server logs are taxing up a large amount of space. There is no central log server. Which of the following would help free up disk space?

  A. Log rotation
  B. Log shipping
  C. Log alerting
  D. Log analysis
  A. Log rotation

  ---

  Explanation

  Log rotation is a process of automatically moving old log files to an archive location and creating new log files. It helps to prevent the accumulation of old log files that can take up a large amount of disk space. By implementing log rotation, the server technician can ensure that the server logs are managed and maintained in a more efficient way, freeing up disk space.

  Log shipping is a process of forwarding log data to a central log server, which is not relevant to this scenario as there is no central log server. Log alerting is a process of generating alerts when specific events occur in the log files, which is not directly relevant to freeing up disk space. Log analysis is the process of analyzing log data to identify trends, patterns, and potential issues, which also does not directly address the issue of low disk space.

• Question 342:

  A technician is configuring a point-to-point heartbeat connection between two servers using IP addressing. Which of the following is the most efficient subnet mask for this connection?

  A. /28
  B. /29
  C. /30
  D. /32
  C. /30

  ---

  Explanation

  The most efficient subnet mask for a point-to-point heartbeat connection between two servers using IP addressing is /30. A /30 subnet mask has 255.255.255.252 as its decimal representation and 11111111.11111111.11111111.11111100 as its binary representation. This means that there are only two bits available for the host portion of the IP address, which allows for four possible combinations: 00, 01, 10, and 11. However, the first and the last combinations are reserved for the network address and the broadcast address, respectively. Therefore, only two IP addresses are usable for the point-to-point connection, which is the minimum required for such a link.A /30 subnet mask is also known as a point- to-point prefix because it is commonly used for point-to-point links between routers or servers1. A /28 subnet mask has 255.255.255.240 as its decimal representation and 11111111.11111111.11111111.11110000 as its binary representation. This means that there are four bits available for the host portion of the IP address,which allows for 16 possible combinations. However, two of them are reserved for the network address and the broadcast address, respectively. Therefore, 14 IP addresses are usable for the subnet, which is more than needed for a point-to-point connection and would result in wasted addresses. A /29 subnet mask has 255.255.255.248 as its decimal representation and 11111111.11111111.11111111.11111000 as its binary representation. This means that there are three bits available for the host portion of the IP address, which allows for eight possible combinations. However, two of them are reserved for the network address and the broadcast address, respectively. Therefore, six IP addresses are usable for the subnet, which is still more than needed for a point-topoint connection and would result in wasted addresses. A /32 subnet mask has 255.255.255.255 as its decimal representation and 11111111.11111111.11111111.11111111 as its binary representation. This means that there are no bits available for the host portion of the IP address, which allows for only one possible combination: all ones. Therefore, only one IP address is usable for the subnet, which is not enough for a point-to-point connection and would result in an invalid configuration. Therefore, a /30 subnet mask is the most efficient choice for a point-to-point heartbeat connection between two servers using IP addressing because it provides exactly two usable IP addresses without wasting any addresses or creating any conflicts1.

• Question 343:

  Which of the following should an administrator use to transfer log files from a Linux server to a Windows workstation?

  A. Telnet
  B. Robocopy
  C. XCOPY
  D. SCP
  D. SCP

  ---

  Explanation

  The administrator should use SCP to transfer log files from a Linux server to a Windows workstation. SCP (Secure Copy Protocol) is a protocol that allows secure file transfer between two devices using SSH (Secure Shell) encryption. SCP can transfer files between different operating systems, such as Linux and Windows, as long as both devices have an SSH client installed. SCP can also preserve file attributes, such as permissions and timestamps, during the transfer.

• Question 344:

  Which of the following concepts is in use when dual power supplies are connected to different power sources?

  A. Fault tolerance
  B. Active-passive
  C. Component redundancy
  D. Heartbeat
  E. Link aggregation
  A. Fault tolerance

• Question 345:

  Joe, a technician, wants to con gure a server's networking information so he will no longer need to maintain a list of names and IP addresses in a le on the server. Which of the following will work BEST to accomplish this task?

  A. DHCP
  B. Hosts le
  C. DNS
  D. VLAN
  C. DNS

• Question 346:

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

  ---

  Explanation

  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 347:

  Which of the following is an architectural reinforcement that is used to attempt to conceal the exterior of an organization?

  A. Fencing
  B. Bollards
  C. Camouflage
  D. Reflective glass
  C. Camouflage

  ---

  Explanation

  Camouflage is an architectural reinforcement that is used to attempt to conceal the exterior of an organization. Camouflage is a technique of blending in with the surroundings or disguising the appearance of a building or facility to make it less

  noticeable or identifiable. Camouflage can reduce the visibility and attractiveness of a target for potential attackers or intruders.

• Question 348:

  A user cannot save large files to a directory on a Linux server that was accepting smaller files a few minutes ago. Which of the following commands should a technician use to identify the issue?

  A. pvdisplay
  B. mount
  C. df -h
  D. fdisk -l
  C. df -h

  ---

  Explanation

  The df -h command should be used to identify the issue of not being able to save large files to a directory on a Linux server. The df -h command displays disk space usage in human-readable format for all mounted file systems on the server. It shows the total size, used space, available space, percentage of use, and mount point of each file system. By using this command, a technician can check if there is enough free space on the file system where the directory is located or if it has reached its capacity limit.

• Question 349:

  An administrator is investigating several unexpected documents and video files that recently appeared in a network share. The administrator checks the properties of the files and sees the author's name on the documents is not a company employee. The administrator questions the other users, but no one knows anything about the files. The administrator then checks the log files and discovers the FTP protocol was used to copy the files to the server.

  Which of the following needs to be done to prevent this from happening again?

  A. Implement data loss prevention.
  B. Configure intrusion detection.
  C. Turn on User Account Control.
  D. Disable anonymous access.
  D. Disable anonymous access.

  ---

  Explanation

  D. Disable anonymous access.

  The fact that the FTP protocol was used to copy the files to the server suggests that the network share has anonymous access enabled. Disabling anonymous access would require users to authenticate before accessing the share, which would prevent unauthorized access and file transfers from external sources.

  Data loss prevention (A) and intrusion detection (B) are both important security measures, but they may not necessarily prevent unauthorized access to a network share. User Account Control (C) is a feature in Windows that helps prevent unauthorized changes to a computer, but it is not directly related to preventing unauthorized access to a network share. Therefore, the best option in this scenario would be to disable anonymous access.

  A. High availability
  B. VMotion
  C. Live migration
  D. Disaster recovery
  D. Disaster recovery

  ---

  Explanation

  Hyper-V Replica is a feature in Microsoft's Hyper-V virtualization platform that enables asynchronous replication of virtual machines to a secondary location. This technology is primarily designed for disaster recovery scenarios, allowing organizations to restore services in the event of site failures.
