Match the application-layer protocol with its description or example.

A 

video streaming platform is optimising its HTTP

communication to ensure smooth playback and fast loading times. The platform

needs to efficiently deliver multiple chunks of video data while minimising

connection overhead. The development team is considering whether to use

persistent or non-persistent HTTP.

non-persistent HTTP are correct? (

Consider the figure below, in which a single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link.

Suppose that the packet length is L= 16000 bits, and that the link transmission rate along the link to router on the right is R = 10 Mbps

What is the

maximum number of packets per second that can be transmitted by the link?

What is the main purpose of networking standards?

A company website experiences a DDoS attack, preventing customers from

accessing online services. Which network security principle is most affected?

John is setting up various internet services for different locations. He

needs to choose the appropriate access networks for each setting. Here's the

list of services he's working with:

1. John is moving into a new

   house and wants high-speed internet directly to his home, choosing between

   fiber-optic broadband or DSL.

2. John needs a mobile hotspot

   to access the internet while traveling for business.

3. John works for a university

   and needs to connect to the campus network.

Match each access network type to its appropriate example from John's options.

A

company is developing a real-time stock trading application that requires reliable

and ordered delivery of transaction data. To ensure smooth communication,

the application establishes a connection between the client and the server

before data exchange. During the session, data flows in both directions

simultaneously without interruption. Additionally, mechanisms are in place

to prevent the sender from overwhelming the receiver by dynamically

adjusting the data flow.

Based on the scenario, which

of the following characteristics of TCP are being utilized?

(More than one option can be correct.)

Consider sending a packet from a source host to a destination host over a fixed route. Which of the following are delay components in the end-to-end delay.
