D386 Hardware and Operating Systems Essentials - Set 5 - Part 1

Correct Answer: To protect data from loss or corruption

A backup strategy ensures that copies of data are available to recover from loss due to hardware failures, accidental deletions, or disasters.

Correct Answer: On-demand access to shared computing resources

Cloud computing allows users to access and utilize computing resources over the internet, enabling flexibility and scalability without the need for local infrastructure.

Correct Answer: To direct data packets to specific devices within a local network

Network switches intelligently route data to the appropriate devices on a local network, improving efficiency and reducing congestion.

Correct Answer: Faster data access and transfer speeds

SSDs utilize flash memory technology, resulting in significantly quicker data access and transfer speeds compared to traditional spinning HDDs.

Correct Answer: Improved data availability and reliability

Distributed databases enhance data availability and fault tolerance by spreading data across multiple locations, reducing the risk of data loss.

Correct Answer: It hides specific data elements to protect privacy

Data masking alters sensitive data to prevent unauthorized access while maintaining the usability of the data for development or testing purposes.

Correct Answer: To monitor and analyze network traffic for suspicious activities

IDS systems detect and alert administrators to potential security breaches or threats, helping to protect network integrity.

Correct Answer: It allows multiple virtual servers to run on a single physical server

Server virtualization maximizes resource utilization and flexibility by enabling multiple virtual servers to operate independently on one physical machine.

Correct Answer: A method of tricking individuals into providing sensitive information

Phishing attacks typically involve deceptive emails or websites that lure users into revealing personal information, such as passwords or credit card numbers.

Correct Answer: To improve security and performance by isolating different segments of a network

Network segmentation enhances security by limiting access to sensitive data and reducing traffic congestion, allowing for better performance.

Correct Answer: It offers scalable resources with minimal capital expenditure

Public clouds provide organizations with flexible resources that can be scaled according to demand, reducing the need for significant upfront investment.

Correct Answer: To run and manage applications for users

Application servers host and execute applications, providing users with the necessary business logic and processing capabilities.

Correct Answer: Virtual Private Network

A VPN creates a secure, encrypted connection over a less secure network, such as the internet, protecting data from unauthorized access.

Correct Answer: It provides data redundancy with efficient storage utilization

RAID 5 uses parity data distributed across multiple disks, allowing for data recovery in the event of a single disk failure while maximizing storage efficiency.

Correct Answer: To define rules and conventions for communication between network devices

Network protocols establish standards for data transmission and communication, ensuring that devices can effectively share information.

Correct Answer: To protect individual devices from threats and vulnerabilities

Endpoint security solutions safeguard devices such as computers and mobile phones from malware, unauthorized access, and other cyber threats.

Correct Answer: It filters incoming and outgoing network traffic based on security rules

Firewalls enforce security policies by monitoring and controlling data flow to and from a network, protecting it from unauthorized access.

Correct Answer: Any software designed to disrupt, damage, or gain unauthorized access to a computer system

Malware includes various malicious software types, such as viruses, worms, trojans, and ransomware, all aimed at compromising system security.

Correct Answer: Clients request resources and servers provide them

Client-server architecture allows multiple clients to request services from centralized servers, optimizing resource management and accessibility.

Correct Answer: To provide encryption for data transmitted over the internet

SSL certificates secure online communications by encrypting data transmitted between web servers and browsers, ensuring privacy and protection.
