Q:

When was the last time you were angry? What happened?

Answer

Anger to me means loss of control. I do not lose discipline. When I get pressured,I step back, I will take a long breath, thoughtfully think through the situation and then start to formulate a course of action. For example, when I am given multiple projects to complete in a short period of time, rather than feeling frustrated, I come up with an approach for the way how to finish the work in a consistent, methodical manner that will not overwhelm me.

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.
