NEW QUESTION 115
Which of the following description of the extended ECC is correct? (Multiple Choice)
- A. Extended ECC is divided into automatic extended ECC and manual extended ECC. One network element can only support one mode at the same time. These two methods cannot be directly docked.
- B. In the automatic extended ECC mode, you need to connect the Ethernet ports of the two NEs with a direct-connected network cable (or a standard network cable through B), extend the ECC, and specify the server and client.
- C. The scale of the extended ECC network (the sum of the server and the client) must not exceed 8.
- D. Extended ECC recommends to use manual basis, which reduces mutual negotiation between network elements.
Answer: A,C,D
