The correct order for CompTIA's troubleshooting strategy is to first establish the symptoms, then establish what changed, identify the infected area, select the most probable cause, implement a solution, test the result, recognize potential effects, and finally document the solution. This order allows for a systematic approach to troubleshooting, starting with understanding the problem and gathering information, then narrowing down the possible causes and implementing a solution, and finally documenting the process for future reference.

54. For Token Rings, MAU and MSAU are the same thing

True

False

The statement is true because in the context of Token Rings, both MAU (Media Access Unit) and MSAU (Multi-Station Access Unit) refer to the same device. MAU is a term commonly used in IBM Token Ring networks, while MSAU is the term used in IEEE 802.5 Token Ring networks. Both terms describe the device responsible for connecting multiple stations in a Token Ring network and managing access to the network. Therefore, in the context of Token Rings, MAU and MSAU are indeed the same thing.

55. You are setting up a new computer with one Hard Drive and One DVD RW drive, how would you set this up in IDE?

HDD Primary Master: DVD Primary Slave

DVD Primary Master: HDD Primary Slave

HDD Primary Master: DVD Secondary Master

HDD Primary Master: DVD Secondary Slave

HDD Secondary Salve: DVD Primary Master

Because IDE can only perform one operation per channel at a time, Copying something from HDD to DVD would be slower if they were on the same drive than if they were on different channels. With multiple IDE devices, configure it depending on what kind of file transfers you will do the most.

56. What type of RAM is this?

SIMM

DDR

SDRAM

SODIMM

RDRAM

The essentials exam may ask you to identify RAM and these can be difficult because RAM looks alike. SD-RAM is can be identified because it has 2 notches along the pins. DDR and SIMM have 1 notch but SIMM has far fewer pins then DDR. SIMM is considered legacy its unlikely is will appear in the exam. RDRAM usually has a metal cover that makes them easily identifiable and SODIMMS only have 4 black rectangles that make them stand out. It is highly unlikely you’ll be asked to identify between DDR and DDR2 but DDR2 has small black squares instead of long rectangles but this depends on the manufacturer. The notch of DDR 2 is also different

59. RAID 10 is the combining of RAID 1 and RAID 0

True

False

RAID 10 is a combination of RAID 1 and RAID 0. RAID 1 involves mirroring, where data is duplicated across multiple drives for redundancy, while RAID 0 involves striping, where data is split across multiple drives for improved performance. RAID 10 combines these two techniques by mirroring the striped data. This provides both redundancy and improved performance, making it an ideal choice for applications that require high levels of data protection and speed. Therefore, the statement that RAID 10 is the combining of RAID 1 and RAID 0 is true.

63. What is a power surge?

A sudden short rise in voltage

A sudden longer rise in voltage

A sudden drop in voltage

The same thing as a brownout

A power surge refers to a sudden longer rise in voltage. This means that there is a sudden increase in the electrical potential between two points in an electrical circuit. Power surges can occur due to various reasons such as lightning strikes, faulty wiring, or switching off high-powered electrical devices. These surges can potentially damage electronic devices and appliances connected to the power supply, which is why surge protectors are commonly used to prevent such damage.

71. You hear a beep coming from your computer every five minutes, you check the CPU temperature and its fine so you shut the computer but the beeping continues, what is your next step.

Replace BIOS battery

Remove power cable and see if beeping continues

Disconnect power from motherboard and see if beeping continues

Check to see if anything else is causing the beeping

Check to see if all cables are inserted properly

This happened to me as an April Fools prank. A cell phone with a dead battery was placed behind the computer and after it continued after the computer had been shut down. With the beeping continuing without the computer was shut down, I realized that it was something else. This does happen with computer repair, a work mate had someone who swore that their computer was playing Christmas tunes but it turned out to be a musical Christmas card in a draw under the computer.
