Q:

What is a stub network?

A) A network with only one entry and no exit point. B) A network that has only one entry and exit point.
C) A network with more than one exit point. D) A network with more than one exit and entry point.
 
Answer & Explanation Answer: B) A network that has only one entry and exit point.

Explanation:

A stub network has only one default path to non-local hosts and no outside network knowledge. Non-local stub network traffic uses a single logical path when traveling in and out of the network.

 

Stub networks are essentially local area networks (LAN) that either do not connect to the outside and relay data packets internally or are dead-end LANs that know of only one network exit. Stub networks may have multiple connections but use one path to single points of destination.

 

Hence, a stub network is a network that has only one entry and exit point.

Q:

In which layer is the pressure the highest?

A) Ionosphere B) Stratosphere
C) Troposphere D) Inner core
 
Answer & Explanation Answer: D) Inner core

Explanation:

"Pressure" is the ratio of mass to area. So, for any given area, the one with more mass pressing on it will experience a higher pressure.

 

As you go more deeply into the atmosphere OR earth itself, you are putting more and more mass over you. For the same unit area therefore, the pressure, (mass/area) increases.

 

Hence, the lowest layer will always have the highest pressure i.e, inner core.

A) 2 years B) 4 years
C) 6 years D) 8 years

Manogna’s age be 0 when she was born.

Her father’s age = 38 years

Her mother’s age when Manogna’s brother who is 4 years younger to her was born = 36 years
