Which of the following is FALSE about routers and routing on the internet?

The central DNS server determines the shortest route for a packet to take between two IP addresses.

Each router independently determines how to pass along each packet it receives.

Packets often arrive in the wrong order or are lost entirely.

Routers will attempt to find the quickest route to the packet's destination based on the information available to the router's software.

What information could you NOT determine ONLY from reading the router logs when we were chatting on the internet simulator in class?

The name of the person sending the message.

What IP address was sending a message.

What IP address was receiving a message.

Which of the following is true about TCP/IP packets?

Packets that are part of the same message may take different routes from sender to receiver.

TCP guarantees that no packets are dropped in transit.

Packets must arrive in the correct order at the receiver.

If a packet is dropped, the entire message must be resent in order.

The loose organization of citizens and engineers that defines protocols and standards for the internet is called the:

Internet Engineering Task Force (IETF)

National Science Foundation (NSF)

United Nations Internet Federation (UNIF)

How does a computer resolve a domain name into an IP address?

It asks its assigned DNS server.

It is provided by the DHCP server on the server's subnet.

What is the main advantage of IPv6 over IPv4?

A much larger number of unique IP addresses is available.

More than 4 gigabytes of memory can be used on the internet with IPv6.

Greater resistance to DDoS attacks.

Higher bandwidth for streaming video.
