A technician is checking a server rack. Upon entering the room, the technician notices the tans on a particular server in the rack are running at high speeds. This is the only server in the rack that is experiencing this behavior. The ambient temperature in the room appears to be normal. Which of the following is the MOST likely reason why the fans in that server are operating at full speed?
Correct Answer: C
Explanation This is the most likely reason why the fans in that server are operating at full speed while the ambient temperature in the room is normal and the other servers in the rack are not experiencing this behavior. A fan failure is a situation where one or more fans in a server stop working or malfunction due to wear and tear, dust, or other factors. This can cause overheating and performance issues on the server. To prevent this, most servers have a fan redundancy feature that allows the other fans to increase their speed and airflow to compensate for the failed fan and maintain a safe temperature level. The server is not likely to be in the process of shutting down, as this would not cause the fans to run at high speeds. An incorrect fan size is not likely to be inserted into the server, as most fans are standardized and compatible with the server chassis and motherboard. The server is not likely to be utilizing more memory than the other servers, as this would not cause a significant increase in temperature or fan speed.

A new 40GB NIC has just been installed in a server but is not detected within the Windows server OS. Which of the following would most likely fix the issue?
Correct Answer: A
Updating the firmware on the NIC is the most likely solution to fix the issue of a new 40GB NIC not being detected within the Windows server OS. Firmware is a software program that controls the functionality of a hardware device, such as a NIC (network interface card). A NIC is a device that enables network communication for a server by providing an interface between the server and the network cable or wireless connection. Updating the firmware on the NIC can improve its performance, compatibility, and stability with the server OS and network protocols.

A server administrator just installed a new physical server and needs to harden the OS. Which of the following best describes the OS hardening method?
Correct Answer: A
Applying security updates is one of the common operating system hardening methods that can help protect the OS from cyberattacks and vulnerabilities. Security updates are released by the OS developer to fix bugs, patch security holes, and improve performance. By installing the latest updates, the server administrator can ensure that the OS is up to date and secure12.
SK0-005 Exam Question 75
The Chief Information Officer of a data center is concerned that transmissions from the building can be detected from the outside. Which of the following would resolve this concern? (Select TWO).
Correct Answer: C,D
Explanation Signal blocking is a technique that prevents or reduces the transmission of electromagnetic signals from a building to the outside. Signal blocking can be achieved by using materials that absorb, reflect, or scatter the signals, such as metal, concrete, or mesh. Signal blocking can protect the data center from eavesdropping, interference, or jamming by unauthorized parties1. Camouflage is a technique that disguises or conceals the appearance of a building to make it less noticeable or identifiable from the outside. Camouflage can be achieved by using colors, patterns, shapes, or vegetation that blend in with the surrounding environment. Camouflage can protect the data center from detection, reconnaissance, or targeting by hostile parties
