Question 43
Which security measure protects data by making it unreadable to unauthorized users?
A) Encryption B) Firewall C) Redundancy D) Authentication
Correct Answer: A) Encryption
Explanation: Encryption converts data into a coded format that is unreadable to unauthorized users, ensuring its confidentiality and protection during transmission or storage.
Question 44
What type of memory retains data even when the computer is powered off?
A) RAM B) Cache C) ROM D) Flash Memory
Correct Answer: C) ROM
Explanation: ROM (Read-Only Memory) is non-volatile memory that retains data even when the computer is powered off, storing critical system instructions.
Question 45
Which of the following describes a denial-of-service (DoS) attack?
A) Flooding a server with excessive traffic to disrupt its normal operations B) Stealing sensitive data from a server C) Installing malicious software to damage a system D) Gaining unauthorized access to a network
Correct Answer: A) Flooding a server with excessive traffic to disrupt its normal operations
Explanation: A DoS attack overwhelms a server with traffic, rendering it unable to process legitimate requests and disrupting its normal operations.
Question 46
What is the main purpose of RAID in data storage?
A) Compress data for easier storage B) Encrypt data for security C) Improve data redundancy and performance D) Increase network bandwidth
Correct Answer: A. Sandbox
Explanation: A Sandbox is an isolated environment used for testing and development to prevent potential security issues from affecting production systems. Encryption protects data, MFA strengthens access control, and VPN secures network communications.
Question 47
Which type of cloud computing service provides development environments and tools over the internet, allowing developers to build applications without managing underlying infrastructure?
A) SaaS B) IaaS C) PaaS D) DaaS
Correct Answer: C) PaaS
Explanation: Platform as a Service (PaaS) provides developers with environments and tools for building applications, without the need to manage servers, storage, or networking.
Question 48
Which of the following backup strategies provides the quickest recovery time in the event of data loss?
A) Incremental Backup B) Differential Backup C) Full Backup D) Mirror Backup
Correct Answer: D) Mirror Backup
Explanation: A mirror backup maintains an exact copy of the data in real-time, making it the fastest option for recovery in the event of data loss.
Question 49
Which network topology provides the most redundancy by connecting every device directly to every other device?
A) Bus B) Star C) Ring D) Mesh
Correct Answer: D) Mesh
Explanation: In a mesh topology, every device is connected to every other device, providing the highest level of redundancy and reliability.
Question 50
What does the acronym RAID stand for in computing?
A) Random Access Information Drive B) Redundant Array of Independent Disks C) Real-time Advanced Information Database D) Read Access and Information Drive
Correct Answer: B) Redundant Array of Independent Disks
Explanation: RAID stands for Redundant Array of Independent Disks, a technology used to improve data redundancy and performance by distributing data across multiple drives.
