a) It assigns IP addresses to devices on a network

b) It ensures reliable, ordered delivery of data between applications

c) It translates domain names to IP addresses

d) It encrypts data for secure transmission

Question 10: FTP vs SFTP

What is the primary advantage of SFTP over FTP?

a) SFTP is faster for transferring large files

b) SFTP encrypts file transfers, providing better security

c) SFTP doesn't require authentication

d) SFTP can transfer more file types than FTP

Question 11: SSL/TLS Certificates

What is the primary purpose of an SSL/TLS certificate on a website?

a) To make the website load faster

b) To authenticate the website's identity and enable encrypted connections

c) To improve search engine rankings only

d) To compress website images automatically

Question 12: Authentication vs Authorization

What is the difference between authentication and authorization?

Part 3: Open-Ended Questions (Medium-Hard - Q16-20)

Provide detailed explanations demonstrating your understanding

Question 16: E-Commerce Security

An e-commerce website needs to securely process customer credit card payments. Explain three specific security measures that should be implemented to protect customer data during transmission and storage. For each measure, describe how it contributes to overall security.

Question 17: Data Packets Journey

Describe the journey of data packets from when a user types a URL in their browser until the webpage is displayed. In your answer, explain the role of at least three different protocols (DNS, TCP/IP, HTTP/HTTPS) and how they work together in this process.

Question 18: Encryption Keys

Explain the difference between symmetric and asymmetric encryption, including how encryption keys are used in each approach. Provide one advantage and one disadvantage for each encryption method.

Question 19: Big Data and Streaming Services

A video streaming service like Netflix handles massive amounts of data from millions of users. Explain how data mining and metadata contribute to improving user experience and service management. Provide specific examples of what data might be collected and how it could be used.

Question 20: Protocol Ports and Security

Different web protocols use different port numbers (e.g., HTTP uses port 80, HTTPS uses port 443). Explain why port numbers are necessary in network communication and discuss the security implications of leaving certain ports open on a web server. Provide at least two specific examples of ports and their associated risks.
