Quiz 2 - CNDC

What are the TWO approach in Media Access Control?

• Convention Access & Convenient Access

• Contention Access & Controlled Access

• Computational Access & Coding Access

• Co-existent Access & Co-parenting Access.

What do you understand on "Access Request" in a definition of Media Access Control

• Each Device must get "Permission" to transmit.

• media such as video & image need approved

• Every Request in need of admin

• All of the above

Where does the User Datagram Protocol operates?

• Network Layer

• Application Layer

• Transport Layer

• Data Link Layer

What's the different between IPv4 & IPv6

• IPv4 is the most common version of IP used while IPv6 is less used due to complication.

• IPv4 : 32-bit Addresses while IPv6 : 128-bit.

• in IPv4 addresses cam easily be exhausted due to limitation no of usage.

• All of the Above

The image here shown the sample of TCP 3 way Handshake. Which one of the process is correct.

• 1. 1. SYN - SENT

  2. 2. SYN - RECEIVED

  3. 3. ESTABLISHED

  4. 4. ESTABLISHED

• 1. 1. SYN - SENT

  2. 2. SYN - ACKNOWLEDGE

  3. 3. SYN - RECEIVED

  4. 4. SYN - COMPLETE

• 1. 1. SYN - SENT

  2. 2. SYN - SENT

  3. 3. ACKNOWLEDGE

  4. 4. SYN - ACKNOWLEDGE

• 1. 1. SYN - PREP

  2. 2. ACK - RECEIVED

  3. 3. RCV - ESTABLISHED

  4. 4. ACKNOWLEDGE

Centralized Routing vs Decentralized Routing based on CNDC terms

• Centralized : Router Middle while Decentralized : Router everywhere.

• Centralized : Headquarter while Decentralized : Local Based.

• Centralized : Routing decide by only one computer while

  Decentralized : Decision was made by each device independently of one another.

• All of the Above

What are the "Operation" responsibility of a Routing Information Protocol (RIP)?

• Very complex network whereby its help to shortcut the connectivity.

• • - network manager builds the routing table.

  • - routing tables broadcast periodically (every minute)

  • - each computer are added, router counts "hops" & selects the shortest route.

• • - network admin builds the server

  • - all the server is locally intervene

  • -

• • - network are complicated in generating transfer among the nodes

  • - all the necessary routing will be fully access from router.
