It disables redundant paths and only leaves one broadcast path in a mesh network. It then enables a previous blocked path if one of the primary links becomes disconnected. This creates a network that won't cause broadcast storms but still provide redundancy.
STP operates at the Data Link layer of the OSI model which prevents traffic loops. STP chooses only one root switch/bridge, out of which all data paths span out logically getting the data to the target the quickest and detect and correct link failures when a switch/bridge fails...STP stands for Spanning Tree Protocol. The root is chosen based on its BID( Bridge ID) which is the combination of a 2 byte priority field and the bridge/switch MAC address....Since all switch/bridges on the network start out with the same priority, the one with the lowest MAC address becomes the root bridge.

STP is basically used for loop prevention and to prodive redundancy. Devices participating in STP perform a root bridge election process. Device having the lowest priority will be choosen as the root bridge. If every device participating in STP have the same priority value, device with the lowest mac-address becomes the root bridge. The root bridge will be responsible to make th overall traffic flow decision on the LAN. Non-root bridges use a lowest cost path to reach the root bridge. This cost is dependent on the interface speed. Topological changes downstream from the root bridge is communicated to the root bridge.
This is tricky as they are clearly concerned about your interest/ability to travel frequently/all the time. I would have enjoyed this aspect of the job but I found it hard to express this beyond simply stating that the travel wasn't an issue. It is also difficult as your willingness to travel might also depend on the opportunity including pay etc... I think one would be hesitant to leave their current position and take on the additional travel for little/no increase in your comp. It might come down to weighing things out when you get an idea about comp etc.. Sadly, after a phone interview and two in person interview rounds where I talked with 6 or 7 members of the team - there was no follow up or information about comp and no offer.
Yes! I love to travel. I already travel within my current role and am at a point in my life where I don’t have any dependencies. The variety of visiting new towns and working on new challenging projects is what led me to consulting in the first place. I utilize Skype and Facebook to stay in touch with friends and family as well as meeting new friends on the road. You always meet new and interesting people while traveling. Consulting gives you this opportunity. I would welcome international travel too!
Proactively work with the individual letting them know the importance of satisfying the customer's needs. If still resistant, go to the next level and advise a supervisor. Keep perserverance and double check to make certain that the job was completed.
