Which of the following is true when describing a unicast address?

A

Packets addressed to a unicast address are delivered to a single interface.

B

These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

C

These are like private addresses in IPv4 in that they are not meant to be routed.

D

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?

A

During high-traffic periods

B

After broken links are reestablished

C

When upper-layer protocols require high reliability

Which of the following is true when describing a multicast address?

A

Packets addressed to a multicast address are delivered to a single interface

B

packets are delivered to all interfaces identified with the address. This is also called a one-to-many address

C

A multicast address identifies multiple interfaces and is delivered to only one address. This address can also be called one-to-one-of-many

D

These addresses are meant for nonrouting purposes,but they are almost globally unique, so it is unlikely they will have an address overlap

Which of the following is true when describing a link-local address?

B

These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

C

These are like private addresses in IPv4 in that they are not meant to be routed.

Which of the following is true when describing a unique local address?

A

Packets addressed to a unicast address are delivered to a single interface.

B

These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

C

These are like private addresses in IPv4 in that they are not meant to be routed.

D

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

Which of the following is true when describing an anycast address?

A

Packets addressed to a unicast address are delivered to a single interface.

B

Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.

C

This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.

D

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?

A

Discard it and send an error message back to the originating host

B

Flood the network with the frame

C

Add the source address and port to the MAC address table and forward the frame out the destination port

D

Add the destination to the MAC address table and then forward the frame

(i) What is global warming? How global warming affects the rapid change of climate? (ii) What are the bad impacts of climate change? (iii) How climate change affects the environment of Bangladesh (iv) How global warming can be minimized (v) What should be the role of students to protect the environment.

A

(i) Global warming is the main natural reason and using harmful chemicals in everyday life the main reason created by men. The climate is changing rapidly that result in the rise of the earth's average temperature

B

(ii) Climate change impacts include floods, cyclones, storm surges and drought, ice sheets melting which will seriously affect the agriculture and livelihood especially at the poor.

C

(iii) Bangladesh is one of the largest deltas in the world which is highly vulnerable to Natural Disasters because of its Geographical location, Fiat and low-lying landscape, Population density, Poverty, Illiteracy, Lack of Institutional setup, etc.

D

(iv) To reduce the bad impact of climate change people should be aware of. Tree plantation can reduce global warming which is the main natural reason for climate change. Stop using harmful chemicals can reduce environmental pollution which is the main man
