Resumo de Recurso

Questão 1

Questão
Which of the following is true
Responda
  • 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

Questão 2

Questão
Which of the following are examples of Flat Naming
Responda
  • An auto-increment ID
  • A phone number
  • A file path
  • A hash of file contents used to identify the file

Questão 3

Questão
The Domain Name System is an example of a flat name resolution mechanism
Responda
  • True
  • False

Questão 4

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

Questão 5

Questão
In a recursive name resolution system, name servers communicate directly with each other except for the root name server which also communicates with the client.
Responda
  • True
  • False

Questão 6

Questão
Which of the following is not a technique for resolving a flat name
Responda
  • Distributed Hash Tables
  • Broadcasting the ID requesting the entity to return its current address
  • Leaving pointers when the entity moves
  • Polling the address space

Questão 7

Questão
Which of the following is true
Responda
  • 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
