A systems administrator is preparing to install two servers in a single rack. The administrator is concerned that having both servers in one rack will increase the chance of power issues due to the increased load.
Which of the following should the administrator implement FIRST to address the issue?

  1. Separate circuits
  2. An uninterruptible power supply
  3. Increased PDU capacity
  4. Redundant power supplies

Answer(s): A

Explanation:

The administrator should implement separate circuits first to address the issue of power issues due to the increased load. Separate circuits are electrical wiring systems that provide independent power sources for different devices or groups of devices. By using separate circuits, the administrator can avoid overloading a single circuit with too many servers and reduce the risk of power outages,

surges, or fires. Separate circuits also provide redundancy and fault tolerance, as a failure in one circuit will not affect the other circuit.



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

  1. Bollards
  2. Reflective glass
  3. Security guards
  4. Security cameras

Answer(s): A

Explanation:

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.

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?

  1. Alternate the direction of the airflow
  2. Install the heaviest server at the bottom of the rack
  3. Place a UPS at the top of the rack
  4. Leave 1U of space between each server

Answer(s): B

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.



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

  1. 21
  2. 22
  3. 23
  4. 443

Answer(s): B

Explanation:

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.
