Select one or more of the following:

  • Entities can have more than one access point at a time

  • An entity may change access points

  • Access points should not be tied to a specific address

  • Access points should have a flat name

Question 2 of 7

Medal-premium 1

Which of the following are examples of Flat Naming

Select one or more of the following:

  • An auto-increment ID

  • A phone number

  • A file path

  • A hash of file contents used to identify the file

Question 3 of 7

Medal-premium 1

The Domain Name System is an example of a flat name resolution mechanism

Select one of the following:

  • True
  • False

Question 4 of 7

Medal-premium 1

Which of the following is true about the home-based approach for resolving flat names

Select one or more of the following:

  • Entities have home location that keeps track of entity’s current location

  • Used in Mobile IP

  • The care-of-address stays static but the home address changes as the entity moves

  • When communicating with a mobile entity, the sender first checks the last location for a pointer to the home address

Question 5 of 7

Medal-premium 1

Select one of the following:

  • True
  • False

Question 6 of 7

Medal-premium 1

Which of the following is not a technique for resolving a flat name

Select one of the following:

  • Distributed Hash Tables

  • Broadcasting the ID requesting the entity to return its current address

  • Leaving pointers when the entity moves

  • Polling the address space

Question 7 of 7

Medal-premium 1

Which of the following is true

Select one of the following:

  • Recursive approach has higher performance demand on name servers

  • Iterative approach can use result caching more effectively

  • Iterative approach has higher communication costs

  • In iterative name resolution the client contacts each name server directly at each level
