Question 4

User says no websites load in any browser. How do you troubleshoot it as an internet connection issue?

Answer 4

→ Check if the device is connected to Wi-Fi or Ethernet.
→ If connected, run (ipconfig /all) to check for valid IP, gateway, and DNS.
→ If IP is missing or incorrect, run (ipconfig /release) and (ipconfig /renew).
→ Try to ping the default gateway using (ping <gateway>) to test local network.
→ If successful, ping a public IP like (ping 8.8.8.8) to test external connectivity.
→ If that works, ping a domain like (ping google.com) to check DNS resolution.
→ If DNS fails, flush DNS using (ipconfig /flushdns) or try changing DNS servers.
→ If local pings fail, check physical connection, adapter status, or escalate to networking.</gateway>

Question 5

What steps would you take if a user reports their internet browser is slow?

Answer 5

→ Try the site in a different browser or incognito mode.
→ If it works there, clear cache and cookies in the original browser.
→ If the issue persists, disable/remove extensions, then restart the browser.
→ Check if all websites are slow or just specific ones.
→ If all are slow, run a speed test.

Question 27

What is DNS?

Answer 27

DNS (Domain Name System) is a system that translates human-readable domain names (like www.example.com) into machine-readable IP addresses (like 192.168.1.1). It enables users to access websites by name rather than needing to remember IP addresses.

Question 28

What is DHCP?

Answer 28

DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses to devices on a network, so users don’t have to manually configure their network settings. It simplifies device connectivity by managing IP address distribution.

Question 29

What is the difference between TCP and UDP?

Answer 29

TCP (Transmission Control Protocol) is a connection-oriented protocol that guarantees data delivery with error-checking and acknowledgment messages. It’s used for reliable communication (e.g., HTTP, FTP). UDP (User Datagram Protocol) is a connectionless protocol that sends data without guarantees, offering faster speeds but no error correction. It’s used for real-time applications (e.g., VoIP, video streaming).

Question 29

What is a VPN?

Answer 29

A VPN (Virtual Private Network) is a service that encrypts a user’s internet connection to ensure privacy and security. It allows users to access a network remotely and appear as if they are connected from another location, bypassing restrictions or enhancing security.

Question 30

What is two-factor authentication (2FA)?

Answer 30

2FA is an extra layer of security that requires two forms of identification before granting access to an account or system. The first factor is usually something the user knows (like a password), and the second is something the user has (like a phone or hardware token).

Question 31

What is the difference between a local user account and a domain user account?

Answer 31

Local user account is tied to a single computer and can only access that computer. Domain user account is stored on a central server (Active Directory) and allows access to multiple computers within a network domain, with centralized management of permissions and security.

Question 32

What is an IP address?

Answer 32

An IP address (Internet Protocol address) is a unique identifier for a device on a network. It allows devices to communicate with each other over the internet or within a local network. It can be either IPv4 (e.g., 192.168.1.1) or IPv6 (e.g., fe80::1).

Question 32

What is HTTPS?

Answer 32

HTTPS (HyperText Transfer Protocol Secure) is a secure version of HTTP that encrypts data exchanged between a web server and a browser using SSL/TLS encryption. It ensures that sensitive information, such as passwords and payment details, is securely transmitted.

Question 33

What is a firewall?

Answer 33

A firewall is a network security device or software that monitors and controls incoming and outgoing network traffic. It acts as a barrier to prevent unauthorized access and attacks while allowing legitimate communication.

Question 34

What is the purpose of Task Manager?

Answer 34

Task Manager is a system utility in Windows that allows users to view and manage running processes, monitor system performance, and end tasks. It helps identify processes consuming excessive resources, troubleshoot performance issues, and manage applications.

Question 35

What is a MAC address?

Answer 35

A MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on a network. It is used at the Data Link Layer (Layer 2) and is assigned by the manufacturer, typically found on the hardware (network cards, routers).

Question 36

What is ping?

Answer 36

Ping is a network utility that sends ICMP Echo Request packets to a target IP address or hostname to check if the target device is reachable and to measure the round-trip time for messages sent. It’s often used to check network connectivity.

Question 37

What is a gateway?

Answer 37

A gateway is a network device that connects different networks, often serving as a bridge between a local network (LAN) and the internet (WAN). It routes data between networks and can perform tasks like address translation and protocol conversion.

Question 38

What is DNS caching?

Answer 38

DNS caching is the temporary storage of DNS lookup results on a device or DNS server. When you visit a website, the DNS query result is stored to speed up future access to the site, reducing the need for repeated DNS lookups.

Question 39

What is JavaScript and how does it relate to web browsers?

Answer 39

JavaScript is a programming language used to create interactive and dynamic content on websites. It allows the browser to update content dynamically, handle events (like button clicks), and provide features such as animations, form validation, and interactivity. It is processed by the browser's JavaScript engine.

Question 40

What is cache in the context of web browsers?

Answer 40

Cache is a temporary storage area where a web browser stores parts of websites (like images, scripts, and stylesheets) to speed up subsequent visits. When a user visits a site again, the browser can load parts of the site from the cache rather than downloading them again, improving page load times.

Question 40

What are cookies in web browsers?

Answer 40

Cookies are small pieces of data stored on a user's device by a web browser while browsing. They are used to remember user preferences, login sessions, and other data, allowing for a more personalized and efficient browsing experience. Cookies can be cleared or blocked by users for privacy reasons.
