Topic 6: Supporting Network Services
Which network service automatically assigns IP addresses to devices on a network?
DHCP (Dynamic Host Configuration Protocol).
What is virtualisation in computing?
Virtualisation is the process of creating virtual versions of computing resources such as servers, storage, or operating systems.
Which wireless technology is commonly used to connect mobile devices to headphones and keyboards over short distances?
Bluetooth.
What does an MFP stand for in printing technology?
MFP stands for Multifunction Printer (a device that can print, scan, copy, and sometimes fax).
Which category of operating system is specifically developed for use on mobile devices such as smartphones and tablets?
A mobile operating system.
Which service allows users to access and manage files stored on another computer over a network?
File server (or file sharing service).
What is client-side virtualisation?
Client-side virtualisation is when a virtual machine runs on a local computer (host machine) instead of on a remote server.
What is the purpose of enabling automatic app updates on a mobile device?
To ensure apps receive the latest features, bug fixes, and security updates automatically.
Which type of printer uses liquid ink sprayed through tiny nozzles onto paper?
Inkjet printer.
Why is it important for IT support technicians to avoid using technical jargon when speaking to non-technical users?
To ensure clear understanding and effective communication without confusing the user.
What do we call devices like smart thermostats, IP cameras, and smart TVs that connect to a network and the internet?
IoT (Internet of Things) devices.
What does SaaS stand for, and what does it provide?
SaaS stands for Software as a Service.
It provides software applications over the internet without requiring local installation.
Which laptop component allows users to move the cursor without using an external mouse?
The touchpad (trackpad).
Why is it important to regularly clean a laser printer’s internal components?
To remove excess toner and debris, prevent paper jams, maintain print quality, and extend the printer’s lifespan.
What is the main purpose of documenting a resolved support ticket?
To keep a record of the issue and solution for future reference, reporting, and knowledge sharing.
Which command-line tool is used to test connectivity between two network devices?
Ping.
What is the difference between IaaS and PaaS?
IaaS (Infrastructure as a Service) provides virtualized hardware resources like servers and storage, while PaaS (Platform as a Service) provides a platform for developing and deploying applications without managing the underlying infrastructure.
What is the main purpose of Mobile Device Management (MDM) in an organization?
MDM is used to remotely manage, secure, monitor, and enforce policies on mobile devices within an organization.
If a printer produces faded prints, what is the most likely cause in a laser printer?
Low toner or a failing toner cartridge (possibly a worn drum unit).
What is the purpose of escalation in IT support?
Escalation ensures that complex or unresolved issues are referred to a higher-level technician or specialist for resolution.
If a user can ping an IP address successfully but cannot access a website using its domain name, what is the most likely problem?
A DNS issue (Domain Name System problem).
What is the difference between a Type 1 and Type 2 hypervisor?
A Type 1 hypervisor runs directly on hardware (bare-metal), while a Type 2 hypervisor runs on top of an operating system.
If a smartphone connects to Wi-Fi but cannot access the internet, what are two possible causes?
Possible causes include:
Incorrect IP configuration or DNS settings
Router or ISP issue
Captive portal authentication required
Firewall or network restriction
If multiple users cannot print to a shared network printer, but the printer works locally, what is the most likely problem?
A network connectivity issue, print server issue, or incorrect printer sharing permissions.
What is the difference between a client operating system and a server operating system?
A client operating system is designed for individual users and personal computing tasks, while a server operating system is designed to manage network resources, users, and services for multiple clients.
