Likurg_2 [28]3 years ago

Answer:

b. Only one root port, which is the bridge's port that is closest to the root bridge, can forward.

Explanation:

Spanning Tree Protocol (STP) was architectured to avoid loops by finding redundant links in a network and closing them. To prevent loops in bridging redundant paths must be determined and blocked. Not only this protocol blocks redundant paths but it also activates them in case of a failure in the link.

Steps in the Spanning Tree protocol to select a root free topology:-

1. Elect one Root Bridge

2. Select one Root Port on the non-root bridges

3. Select one Designated Port on each segment

 In step 2

After selecting a Root Bridge all non-root Bridges elect a Root Port. This port has the lowest cumulative path cost towards the Root Bridge.

Why Prithvi Narayan Shah are appointed the person favoured by the people at Kazi
mart [117]

Answer:

At one time, Prithvi Narayan Shah could not decide who he should as the Kaji (equivalent to Prime Minister) and Pradhan Senapati (Commander-in-Chief). He had two commanders Biraj Thapa Magar and Kalu Pande in mind.

So, for the decision, he called a Bhaardaari Sabhaa (assembly of the courtiers) along with some people of his kingdom and chose Kalu Pande on the basis of popularity. He instructs his descendants in Divyopadesh to understand the popularity before nominating someone as the Kaji.

This is not a true democratic system as the candidates don't really come from between the people. The candidates are the two people who the King thinks are capable and only wants to know who is popular. This only seems like a precursor of democracy we have today.

I would not call Prithvi Narayan Shah was a democratic king, though
