Frage 9
Frage
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.)
Antworten
-
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.

Frage 17
Frage
What is a characteristic of the blue-green upgrade deployment strategy?
Antworten
-
A new environment is created with the new code in it, while the old environment is held in reserve in case users experience problems.
-
The code changes are periodically rolled out in such a way that they do not impact current users.
-
The new code is deployed all at once to the old environment. If users experience no issues, it is then moved to the new environment.
-
The new code version is first rolled out to a subset of users. Changes can then be rolled back if the users experience any problems.
