Questão 9

Questão
Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)
Responda
  • The source port field identifies the running application or service that will handle data returning to the PC.
  • The UDP destination port number identifies the application or service on the server which will handle the data.
  • UDP segments are encapsulated within IP packets for transport across the network.
  • TCP is the preferred protocol when a function requires lower network overhead.
  • The TCP source port number identifies the sending host on the network.
  • The TCP process running on the PC randomly selects the destination port when establishing a session with the server.

Responda
  • stateful firewall
  • forward proxy
  • reverse proxy

Questão 15

Questão
What is a characteristic of a virtual machine running on a PC?
Responda
  • A virtual machine needs a physical network adapter to connect to the Internet.
  • A virtual machine runs its own operating system.
  • The number of virtual machines that can be made available depends on the software resources of the host machine.

Responda
  • True

Questão 17

Questão
What is a characteristic of the blue-green upgrade deployment strategy?
Responda
