A network where data is sent in a single, dedicated channel.

A network where data is sent only through a direct channel.

A network where data is sent in large, continuous streams.

What is the function of a router in a packet switching network?

To address and forward packets to their destination.

What is the advantage of dividing data into small packets in a packet switching network?

It makes it easier to resend lost or damaged packets.

It reduces the need for routers.

It increases the size of the data being sent.

What happens if a route becomes unavailable in a packet switching network?

The packet is routed using an alternate route.

The packet is sent back to the sender.

The packet is stored until the route becomes available.

Which layer of the TCP/IP model is responsible for putting frames onto the physical network?

Link or Network Interface layer

Address Resolution Protocol (ARP)

Internet Control Message Protocol (ICMP)

Transmission Control Protocol (TCP)

Which protocol is used for hardware address resolution in the TCP/IP model?

Address Resolution Protocol (ARP)

Transmission Control Protocol (TCP)

Internet Control Message Protocol (ICMP)

Which layer of the TCP/IP model provides communication sessions between computers?

Link or Network Interface layer

What does the Transmission Control Protocol (TCP) provide in the TCP/IP model?

Logical addressing and routing of packets

Sending messages and reports on errors

What is the main advantage of using User Datagram Protocol (UDP)?

It has less overhead involved in processing and transmitting each packet.

It guarantees packet delivery in the correct sequence.

It provides a connection-oriented service.

What is the primary function of the Internet Protocol (IP)?

To provide best effort delivery between hosts

To provide connection-oriented delivery

To ensure packets are delivered in sequence

What is an IP address used for?

To logically identify each device on a network

To physically identify each device on a network

To provide a physical address for each device

How is an IP address typically expressed to make it easier to enter in configuration dialogs?

As four decimal numbers separated by periods

What two pieces of information does an IP address encode?

The network number (network ID) and the host number (host ID)

The network number (network ID) and the subnet mask

The host number (host ID) and the MAC address

The subnet mask and the MAC address

What is the purpose of a subnet mask?

To determine the identity of the network to which the host belongs

To identify the MAC address of a host

To convert binary numbers to decimal

To assign a logical address to a host

What does a network prefix length or subnet mask help to distinguish?

The network ID and host ID portions within an address

The physical address and logical address

The data link layer and network layer

What is the function of the Internet Protocol (IP) at the network layer?

Addressing and forwarding between networks with distinct IDs

Converting binary numbers to decimal

Assigning MAC addresses to hosts

Delivering frames over a local network segment

What is the primary function of the Address Resolution Protocol (ARP)?

To map IP addresses to hardware addresses

To assign IP addresses to hosts

To route packets between different networks

To convert domain names to IP addresses

How do hosts reduce the number of ARP messages that need to be sent?

By caching IP:MAC address mappings

What is the role of a router in the context of ARP messaging?

To forward packets to their destination

To assign MAC addresses to hosts

To convert IP addresses to domain names

What is the default gateway used for in network addressing?

To forward packets to their destination

To assign IP addresses to hosts

To discover local destination hosts

To convert domain names to IP addresses

What is the primary purpose of the Domain Name System (DNS)?

To resolve resource names to IP addresses

To store all possible DNS records in a single server

To create sub-domains for businesses

What is a name server responsible for in the DNS?

Holding records for a part of the namespace

What is a Fully Qualified Domain Name (FQDN)?

A hostname combined with information about the domain

In the DNS query example, what is the first step a resolver (client) takes to establish a session with the www.comptia.org web server?

Sends a recursive DNS query to its local DNS server

Sends a query to the root name server

Sends an iterative query to the .com name server

Sends a query to the comptia.org name server
