D386 Hardware and Operating Systems Essentials - Set 2 - Part 1

Correct Answer: To collect system messages from networked devices

A Syslog server is used to gather log data from various networked devices, helping in monitoring and troubleshooting network issues.

Correct Answer: File share server

A file share server allows users to access and manage files remotely, facilitating collaboration and data sharing across networks.

Correct Answer: Authentication, Authorization, and Accounting

AAA is a framework used for controlling access to computer resources, enforcing policies, and auditing usage.

Correct Answer: A comprehensive security management tool that combines multiple security tools

UTM solutions integrate various security functions, such as firewalls, intrusion detection systems, and antivirus, into a single platform for efficient management.

Correct Answer: To distribute network or application traffic across multiple servers

Load balancers improve application responsiveness and availability by distributing workloads evenly across multiple servers.

Correct Answer: Software that handles all communications from or sent to the Internet

Proxy servers act as intermediaries for requests from clients seeking resources from other servers, providing security and caching benefits.

Correct Answer: Stops unsolicited emails at the gateway before they reach the user

A spam gateway filters incoming emails to prevent unwanted or malicious content from reaching users' inboxes.

Correct Answer: To distribute incoming network traffic across multiple servers

Load balancers help optimize resource use, maximize throughput, minimize response time, and avoid overload of any single resource.

Correct Answer: A diskless workstation that relies on a server for data and applications

Thin clients have minimal processing capabilities and depend heavily on a server for resources, making them cost-effective for many organizations.

Correct Answer: It serves only one customer or organization

A private cloud provides dedicated resources and infrastructure to a single organization, allowing for greater control and security.

Correct Answer: Cloud services available to the general public

Public clouds offer computing resources and services over the internet, accessible to anyone who wants to use them.

Correct Answer: A combination of public and private clouds that remain distinct

Hybrid clouds allow data and applications to be shared between them, providing flexibility and scalability for organizations.

Correct Answer: Networking capabilities and storage

IaaS delivers essential hardware resources such as servers, storage, and networking over the cloud on a pay per use basis.

Correct Answer: A method of renting software applications that are hosted in the cloud

SaaS allows users to access software applications over the internet without needing to install or maintain them on local devices.

Correct Answer: Develop, run, and manage applications without the complexity of infrastructure

PaaS provides a platform allowing developers to create applications without worrying about the underlying hardware and software layers.

Correct Answer: A computer that does not have an operating system and connects to a server

Zero clients rely entirely on a server for processing, making them efficient for environments that require centralized computing.

Correct Answer: To run applications designed for a different operating system

Emulators simulate hardware or software environments, allowing applications written for one system to run on another.

Correct Answer: Multiple "virtual" machines on a single computing device

Virtualization enables the creation of multiple virtual environments on a single physical machine, optimizing resource use and flexibility.

Correct Answer: Software that enables a single computer to run multiple operating systems simultaneously

A hypervisor creates and manages virtual machine instances, allowing for efficient resource allocation and isolation.

Correct Answer: Features defining what a software product must do

Functional requirements specify the desired behaviors and functionalities of a system, guiding development and testing.
