Consider these network components: modem, router, switch, hub, and gateway. If you need to establish internet connectivity and connect 20 computers in one office with failover capability, which setup would be most comprehensive?
- A. Modem connected to hub, then to all computers
- B. Modem to router to switch to computers, with gateway for protocol translation
- C. Modem to router to switch to computers with backup router for failover
- D. Modem to multiple hubs connected in cascade
Answer: C. Modem to router to switch to computers with backup router for failover
This setup provides internet access (modem), network management (router), intelligent switching (switch), efficient device connectivity, and failover capability through a backup router.

A website receives 10,000 daily visitors requesting different product information dynamically. What would be the critical disadvantage of using only static web pages for this scenario?
- A. Static pages cannot use CSS styling
- B. Manual creation and update of thousands of individual HTML files for each product variation and user state
- C. Static pages cannot display images
- D. Static pages consume more server memory
Answer: B. Manual creation and update of thousands of individual HTML files for each product variation and user state
With static pages, you'd need separate files for every product variation and user state, making maintenance impractical. Dynamic pages generate content on-demand from a database.
