Routing Module 2

Front

At which layer of the OSI model do network switches operate that do not support routing?

Back

Data Link

Front

How is the HTTP request from the client routed to the correct service running on the server?

Back

Port or socket number

Front

What do the server and the client use to keep each download separate when a client computer downloads files from an FTP server and initiates a second download?

Back

Session ID

Front

What is the first thing that happens when a collision occurs on an Ethernet network?

Back

The device that detected the collision transmits a jam signal.

Front

How does TCP handle data sequencing?

Back

TCP breaks user data into segments, numbers each segment, places them in the correct sequence, and sends each one in order, waiting for an acknowledgement before sending the next segment.

Front

Which OSI model layers perform the following functions: 1. Logical topology, hardware addresses, media access, framing 2. Logical device identification, path identification, and selection 3. Flow control, reliable data transfer, windowing, segmentation, and sequencing 4. Converting data to 0s and 1s, bit signaling, and synchronization?

Back

Data Link, Network, Transport, Physical

Front

What role does ARP play in the routing process?

Back

If a router does not know a destination device's MAC address, it sends an ARP broadcast containing the destination device's IP address and requesting its MAC address.

Front

What is the purpose of a network model?

Back

Standardize processes at each layer.

Front

The process of breaking a message into packets, adding control information and other information, and then transmitting the message through the transmission medium is known as ________?

Back

Encapsulation

Front

During network transmission, data is transferred to various routers, which forward the data to the appropriate network. If the source and destination network addresses reside on the same network, which protocol is used to determine the MAC address of the destination IP address?

Back

ARP
