#4. A network segment has a bandwidth of 10 Mbps, and packets experience an end-to-end latency of 100 ms. What is the bandwidth-delay product of the network segment?

The bandwidth-delay product of a segment is the measure of the maximum number of bits that can be on the segment at any one time. The bandwidth-delay product is calculated by multiplying the segment’s bandwidth (in bits/sec) by the latency that packets experience as they cross the segment (in sec). In this question, the bandwidth-delay product can be calculated as follows: bandwidth-delay product = 10,000,000 bits/sec * 0.1 sec = 1,000,000 bits.

#14. A laptop inside your network has an IP address of 10.1.1.241. Using NAT, a router translates the 10.1.1.241 private IP address into 198.51.100.54, a public IP address, as the laptop is connecting to a web server on the Internet. The web server has an IP address of 203.0.113.10. What type of address is 203.0.113.10 in this scenario?

An outside global address represents a device outside of a network with a globally
routable address. In this scenario, the web server’s IP address of 203.0.113.10 would be
an outside global address.

An inside local address represents a device inside of a network with an address that
is not routable on the public Internet. In this scenario, the laptop’s IP address of
10.1.1.241 would be an inside local address.

An inside global address represents a device on the inside of our network with an
address that is a globally routable address. In this scenario, the laptop’s translated
address of 198.51.100.54 would be an inside global address.

An outside local address represents a device on the outside of a network that has an
address that is not routable on the public Internet. For example, if NAT were being
performed at a remote site, the destination device at the remote site would have an outside
local address. In the scenario presented in this question, there is no outside local address.

Assuming that as many default settings as possible are used on all four routers, which of the following is true about the next-hop IP address for routes R1 learns over its iBGP connection to R2?

#23. A laptop inside your network has an IP address of 10.1.1.241. Using NAT, a router translates the 10.1.1.241 private IP address into 198.51.100.54, a public IP address, as the laptop is connecting to a web server on the Internet. The web server has an IP address of 203.0.113.10. What type of address is 10.1.1.241 in this scenario?

An outside global address represents a device outside of a network with a globally
routable address. In this scenario, the web server’s IP address of 203.0.113.10 would be
an outside global address.

An inside local address represents a device inside of a network with an address that
is not routable on the public Internet. In this scenario, the laptop’s IP address of
10.1.1.241 would be an inside local address.

An inside global address represents a device on the inside of our network with an
address that is a globally routable address. In this scenario, the laptop’s translated
address of 198.51.100.54 would be an inside global address.

An outside local address represents a device on the outside of a network that has an
address that is not routable on the public Internet. For example, if NAT were being performed at a remote site, the destination device at the remote site would have an outside
local address. In the scenario presented in this question, there is no outside local address.
