Which of the following BEST describes a worm?
- Malicious software that is self-replicating and self-propagating
- Malicious software that changes the users home page
- Malicious software attached to another piece of software
- Malicious software that monitors Internet surfing habits
Correct Answer

A. Malicious software that is self-replicating and self-propagating

Explanation

A worm is a type of malicious software that is able to replicate itself and spread to other computers or devices without any action from the user. Unlike viruses, worms do not need to attach themselves to other files or programs in order to spread. They can exploit vulnerabilities in computer networks and use various methods such as email, instant messaging, or file sharing to propagate themselves. The main characteristic of a worm is its ability to independently replicate and spread, making it a self-replicating and self-propagating form of malware.

Which of the following BEST describes the function of ECC in a RAM module?
- Ability to bypass the IRQ channels to work directly with the CPU
- Ability to detect hardware incompatibilities and resolve them
- Ability to detect and correct single bit errors in memory
- Ability to use varying levels of voltage for power saving
Correct Answer

A. Ability to detect and correct single bit errors in memory

Explanation

ECC stands for Error Correcting Code, which is a feature in RAM modules that allows them to detect and correct single bit errors in memory. This means that if there is a bit flip or error in the data stored in a memory cell, ECC can identify and fix it automatically, ensuring the integrity and accuracy of the stored information. By detecting and correcting these errors, ECC helps to improve the reliability and stability of the RAM module.

An external hard drive installation has caused a system to crash. Which of the following would be the BEST startup selection?
- Debugging Mode
- Safe Mode with Command Prompt
- Last Known Good Configuration
- Active Directory Restore Mode
Correct Answer

A. Last Known Good Configuration

Explanation

The best startup selection in this scenario would be "Last Known Good Configuration." This option allows the system to start using the most recent settings that were known to work properly before the crash occurred. By selecting this option, the system can revert back to a stable state and potentially resolve any issues caused by the external hard drive installation. Safe Mode with Command Prompt and Debugging Mode are more suitable for troubleshooting purposes, while Active Directory Restore Mode is specific to domain controllers and not relevant in this situation.
