Cyber I Week 1 Quiz

The (a)   is the portion of the IP address that identifies the network the device is assigned to.

• subnet mask
• Internet Protocol address (IP address)
• Transmission Control Protocol (TCP)
• IP suite

What protocol is used to determine the MAC address of the host using the destination IP address?

What is the definition of a protocol

• A set of standards for communication between network hosts

• A conceptual model and set of communication protocols used on the internet and similar computer networks

• Allows computing devices and application devices to exchange messages over a network

• Used to determine the MAC address of the host using the destination IP address

You've implemented a network where each device provides all other devices on the network with access to shared files.

Which type of network do you have?

• Polling

• Client-server

• Peer-to-peer

• Multiple access

You have a network that uses a logical ring topology. How do messages travel through the network?

• Messages are sent to a central device that forwards them to the destination devices.

• Messages travel from one device to the next until they reach the destination device.

• Messages are sent to all devices connected to the network.

• Messages are sent directly to the destination device only.

What is the basic purpose of the OSI Physical layer?

• Maintain a list of known networks and neighboring routers.

• Define how physical network devices are identified on a network.

• Define when devices have access to the LAN.

• Coordinate rules for sending and receiving electrical signals.

During TCP/IP communication between two network hosts, information is encapsulated on the sending host and decapsulated on the receiving host using the OSI model.

Match the OSI model layer on the left with the appropriate information format on the right.

• Bits

• Network layer

• Segments

• Physical layer

• Packets

• Transport layer

• Frames

• Data Link layer

TCP is a connection-oriented protocol that uses a three-way handshake to establish a connection to a system port. Computer 1 sends a SYN packet to Computer 2. Which packet does Computer 2 send back?

• RST

• ACK

• SYN/ACK

• SYN/RST
