Which of the following actions is the FINAL step in the standard troubleshooting methodology?
Correct Answer: A
Explanation:
The final step in the standard troubleshooting methodology is to document the solution and cause of the problem. This step involves recording the details of the problem, the steps taken to resolve it, the outcome of the solution, and any preventive measures implemented to avoid future occurrences. Documenting the solution and cause can help to create a knowledge base for future reference, improve communication among IT professionals, and facilitate continuous improvement12.

Question 2
Which of the following is a compiled language?
Correct Answer: C
Explanation:
A compiled language is a programming language that requires its source code to be converted into machine code before it can be executed by the CPU. A compiled language uses a compiler, which is a program that translates the source code into an executable file that contains machine code. A compiled language typically runs faster and more efficiently than an interpreted language, which does not need to be compiled before execution. Java is an example of a compiled language that can run on different platforms using the Java Virtual Machine (JVM), which interprets the machine code for the specific hardware1112.

Question 3
A systems administrator uses a program that interacts directly with hardware to manage storage, network, and virtual machines. This program is an example of:
Correct Answer: D
Explanation:
A hypervisor is a software program that allows multiple operating systems (OS) to run on the same physical hardware as virtual machines (VMs). A hypervisor can be classified into two types: Type 1 and Type 2. A Type 1 hypervisor interacts directly with the hardware and does not need an underlying OS to function. A Type 1 hypervisor is also known as a bare-metal hypervisor or a native hypervisor. A Type 1 hypervisor can manage storage, network, and VMs more efficiently and securely than a Type 2 hypervisor89.
