Which two protocols use UDP as a transport protocol by default? (Choose two.)

Which network mask is the equivalent of 255.255.248.0?

You have been assigned the /24 network and need to segment it into at least 60 subnets.
Which network mask meets this requirement?

You must segment your internal /24 network into a minimum of 12 subnets, each containing a
minimum of 12 hosts.
Which network mask do you use?

What are the usable hosts on the .128.0/19 network?

You have been allocated a /22 network.
How many usable hosts are available?

You have been asked to use a 23-bit network mask to segment the network block 209.18.12.0.
How many usable host addresses will there be per subnet?

An administrator is unable to ping any address on the 10.0.19.0/24 subnet. To identify the
problem, the administrator uses the command shown in the exhibit.
Which step should be taken to solve the problem?

interfaces {
ge-0/0/8 {

unit 0 {
family inet {
address 192.168.1.1/24;
} } }
ge-0/0/9 {
unit 0 {
family inet {
address 192.168.10.1/24;
} } }
}

Referring to the exhibit, which command would you use to add an additional address to the ge-
0/0/9.0 interface?

}
targets {

}

Referring to the exhibit, what is the purpose of the targets section of the configuration?
