Please, I would be grateful if anyone can help me with this question.
Which statement describes a characteristic of the frame header fields of the data link layer?
- They all include the flow control and logical connection fields.
- Ethernet frame header fields contain Layer 3 source and destination addresses.
- They vary depending on protocols.
- They include information on user applications.
The correct statement that describes the characteristic of the frame header fields of the data link layer is:
I hope this will be helpful to you ! Good Luck!
if you don’t mind, can you tell me about the reference to this question? I prepare for the exam, I practiced a lot of questions, but I didn’t face these types of questions.
Thank you in advance!
First, I wish you good luck in your exam.
About the question, I prepare also for the CCNA, and I used the premium dumps to practice more and more.
they are valid and useful. a lot of past test takers recommend them.
Oh.. thank you for your fast response, I appreciate it!
Okay, I am gonna look for them. I wish you good luck too in your exam! and don’t hesitate if you want to ask about something. it will be my pleasure to help you!
The correct answer is the third statement. and this is the explanation for it:
All data link layer protocols encapsulate the Layer 3 PDU within the data field of the frame. However, the structure of the frame and the fields that are contained in the header vary according to the protocol. Different data link layer protocols may use different fields, like priority/quality of service, logical connection control, physical link control, flow control, and congestion control.
It is not my field, but I look for it for you. I hope it will be helpful and useful!
