Read the first 7 Internet Architecture flashcards as text

  1. What is an 'autonomous system' (AS) on the internet?

    Answer: A collection of IP networks under the control of a single organization with a unified routing policy

    An autonomous system is a group of IP networks managed by a single organization (like an ISP) that presents a unified routing policy.

  2. What is the significance of port 443 in internet communication?

    Answer: It is the default port for HTTPS (secure web) traffic

    Port 443 is the standard port for HTTPS connections, which use TLS/SSL encryption.

  3. A student sends an email. The message is split into packets that take different routes and arrive out of order. Which protocol reassembles them correctly?

    Answer: TCP

    TCP (Transmission Control Protocol) numbers packets and reassembles them in the correct order at the destination.

  4. Which of the following scenarios best illustrates 'redundancy' in internet infrastructure?

    Answer: Multiple physical paths exist between two cities so traffic can reroute if one cable is cut

    Redundancy means having multiple independent paths or components so the system keeps working if one fails.

  5. What is the function of DHCP (Dynamic Host Configuration Protocol)?

    Answer: Automatically assigns IP addresses and network settings to devices when they join a network

    DHCP automatically provides IP addresses, subnet masks, and gateway info to devices that connect to a network.

  6. Which of the following describes a 'distributed denial-of-service (DDoS)' attack and why internet architecture makes it hard to prevent?

    Answer: Many compromised machines flood a target with traffic; hard to fully prevent because the open, decentralized internet allows traffic from countless sources

    DDoS attacks use many distributed sources to overwhelm a target, and the open nature of the internet makes blocking all sources difficult.

  7. What is the purpose of 'traceroute' (or 'tracert') as a network diagnostic tool?

    Answer: It displays the sequence of routers a packet passes through on its way to a destination

    Traceroute reveals each hop (router) a packet takes to reach its destination, along with latency at each hop.
