Questions

1. How many layers does the OSI model have?

   1. 4
   2. 5
   3. 6
   4. 7
   Show answer

   Answer: 7

   The OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

2. Which protocol is responsible for assigning unique identifiers to devices on a network so data can be routed correctly?

   1. HTTP
   2. FTP
   3. IP
   4. DNS
   Show answer

   Answer: IP

   IP (Internet Protocol) assigns logical addresses (IP addresses) to devices and handles routing of packets across networks.

3. Which port number is associated with HTTPS?

   1. 21
   2. 80
   3. 443
   4. 8080
   Show answer

   Answer: 443

   HTTPS uses port 443 by default. HTTP uses port 80.

4. In the TCP/IP model, which layer corresponds most closely to the OSI model's Application, Presentation, and Session layers combined?

   1. Internet Layer
   2. Network Access Layer
   3. Transport Layer
   4. Application Layer
   Show answer

   Answer: Application Layer

   The TCP/IP model's Application Layer consolidates the OSI model's top three layers: Application, Presentation, and Session.

5. What does a DNS server do when a client requests 'www.example.com'?

   1. Encrypts the web page before sending it
   2. Translates the domain name into an IP address
   3. Compresses packets for faster transmission
   4. Assigns the client a new MAC address
   Show answer

   Answer: Translates the domain name into an IP address

   A DNS server resolves domain names to IP addresses so the client's browser knows which server to connect to.

6. Which of the following is a private IP address range used in local networks?

   1. 8.8.8.8
   2. 172.217.0.0
   3. 192.168.1.0
   4. 104.244.42.1
   Show answer

   Answer: 192.168.1.0

   192.168.x.x is a reserved private IP address range (RFC 1918) used in local area networks and not routable on the public internet.

7. UDP provides guaranteed, ordered delivery of data packets, making it more reliable than TCP.

   Show answer

   Answer: False

   UDP does not guarantee delivery or ordering — it is a connectionless protocol. TCP provides reliable, ordered delivery through acknowledgments and retransmission.

8. The physical path data takes through the internet is determined by devices called ________.

   Show answer

   Answer: routers

   Routers examine packet headers and forward packets along the optimal path through the network to reach their destination.
