Intro Cyber Unit 2 Practice

Your manager has asked you to implement a network infrastructure that will accommodate failed connections. Which of the following network topologies provides redundancy for a failed link?

• Star

• Ring

• Bus

• Mesh

You're an application developer, and you're writing a program for exchanging video files through a TCP/IP network. You need to select a transport protocol that will guarantee delivery. Which protocol provides this capability?

• Transmission Control Protocol (TCP)

• Session Initiation Protocol (SIP)

• User Datagram Protocol (UDP)

• File Transfer Protocol (FTP)

In the OSI model, what is the primary function of the Network layer?

• Enable communication between network clients and services.

• Enable communication between network clients and services.

• Ensure that packets are delivered with no loss or duplication.

• Route messages between networks.

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?

• Multiple access

• Polling

• Client-Server

• Peer-to-Peer

Which of the following protocols allows hosts to exchange messages to indicate problems with packet delivery?

• Trivial File Transfer Protocol (TFTP)

• Dynamic Host Configuration Protocol (DHCP)

• Internet Control Message Protocol (ICMP)

• Internet Group Management Protocol (IGMP)

What is the purpose of a frame check sequence (FCS) footer?

• Checksum error detection

• Control information

• Contain logical network addresses

• Hold segment data

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 (Reset)

• SYN (Sync)/RST (Reset)

• SYN (Sync)/ACK (Acknowlegemenet)

• ACK (Acknowledgement)

You've implemented a network where hosts are assigned specific roles, such as file sharing and printing roles. Other hosts access those resources, but they don't host services of their own. Which type of network do you have?

• Extranet

• Peer-to-Peer

• Client-Server

• Intranet

Which of the following is the process of breaking a message into packets, adding controls and other information, and then transmitting the message through the transmission medium?

• Transformation

• Encapsulation

• Segmentation

• Sequencing

What is the basic purpose of the OSI Physical layer?

• Maintain a list of known networks and neighboring routers.

• Define when devices have access to the LAN

• Coordinate rules for sending and receiving electrical signals.

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