Question 1

____ scanning detects malware by comparing a file's content with known malware signatures in a signature database.&#10;A) Integrity checking&#10;B) Polymorphic&#10;C) Signature&#10;D) Heuristic

Accepted Answer

Signature scanning compares a file's content with known malware signatures in a signature database to identify malware. Integrity checking ensures that a file's contents haven't been tampered with and is not used to detect malware. Polymorphic scanning is a method of malware obfuscation that changes its code on each infection to evade signature-based detection. Heuristic scanning is a form of malware detection that uses a set of rules to identify potential malware based on its behavior patterns.

Question 2

A(n)____ is a deviation from a specified level of system performance for a given period of time.&#10;A) fault&#10;B) failure&#10;C) error&#10;D) hoax

Accepted Answer

A failure is a situation where a system does not meet a specified level of performance over a given period of time. A fault is a defect in a system that can lead to a failure, but a fault does not necessarily mean that a failure has occurred. An error is a mistake that occurs during system development or operation, but it may not necessarily lead to a failure or fault. A hoax is a malicious or deceitful act that is not related to system performance. Thus, the best choice is B.

Question 3

Mesh topologies and ____ topologies are good choices for highly available enterprise networks.&#10;A) star&#10;B) SONET rings&#10;C) bus&#10;D) ring

Accepted Answer

Mesh and SONET rings are both good choices for highly available enterprise networks because they provide redundant paths for data to travel, increasing network reliability and reducing the likelihood of network downtime. Star and bus topologies do not provide the same level of redundancy and are therefore not as suitable for highly available enterprise networks. A ring topology can provide redundancy, but it is not as efficient as a SONET ring topology.

Question 4

A(n)____ virus disguises itself as a legitimate program to prevent detection.&#10;A) stealth&#10;B) encrypted&#10;C) time dependent&#10;D) polymorphic

Accepted Answer

A stealth virus is designed to evade detection by hiding itself from antivirus software. It can modify file sizes or conceal itself in memory, making it difficult for traditional antivirus methods to detect.

Question 5

____ are programs that run independently and travel between computers and across networks.&#10;A) Viruses&#10;B) Worms&#10;C) Bots&#10;D) Trojan horses

Accepted Answer

Worms are self-contained programs that do not require a host application to run and can replicate themselves and travel across networks, often causing damage to computer systems. Viruses require a host application to replicate and spread, bots are automated programs that perform specific tasks, and Trojan horses are programs that appear harmless but actually have malicious intent.

Question 6

____ scanning techniques attempt to identify malware by discovering &#34;malware-like&#34; behavior.&#10;A) Integrity checking&#10;B) Polymorphic&#10;C) Signature&#10;D) Heuristic

Accepted Answer

Heuristic scanning techniques attempt to identify malware by discovering "malware-like" behavior. Heuristic scanners use a variety of techniques to identify potentially malicious code, such as examining code for commands that modify system settings or attempt to delete files. This approach allows for the detection of previously unknown or mutated malware that may not be caught using traditional signature-based approaches.

Question 7

____ offers the best performance.&#10;A) RAID Level 0&#10;B) RAID Level 1&#10;C) RAID Level 3&#10;D) RAID Level 5

Accepted Answer

RAID Level 0 offers the best performance because it uses striping without redundancy, allowing for faster read and write speeds compared to other RAID levels that include redundancy.

Question 8

Power that is free from noise is called &#34;____&#34; power.&#10;A) clear&#10;B) clean&#10;C) filtered&#10;D) white

Accepted Answer

The term commonly used to describe noise-free power is "clean" power. Clean power refers to electricity that is free from interruptions, spikes, surges, noise, or other disturbances that could affect its quality or performance. This type of power is important for sensitive electronics and equipment that require stable and reliable power sources.

Question 9

A program that disguises itself as something useful but actually harms your system is called a ____.&#10;A) virus&#10;B) worm&#10;C) bot&#10;D) Trojan horse

Accepted Answer

A Trojan horse is a type of malware that disguises itself as a harmless program or file but actually contains harmful code. Unlike viruses and worms, Trojan horses do not self-replicate but instead rely on the user to unwittingly install and run them. They can be used to steal personal information, damage or delete files, and even give remote access to the attacker.

Question 10

____ is an automatic distribution of traffic over multiple links or processors to optimize response.&#10;A) Redundancy&#10;B) Failover&#10;C) RAID&#10;D) Load balancing

Accepted Answer

Load balancing is the process of distributing traffic over multiple links or processors to optimize response. Redundancy and failover refer to backup systems and processes for ensuring system availability in case of failures, while RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical disks into a single logical unit.
