1. Which of the followings are PAUSE function's applications? (Multiple Choice)

2. By default, in the MSTP protocol that is configured by the switch. What is number of the parameter that all fields set in MSTP configuration table?

3. Configure PPPOE users under ME60. It fails when user try to dial.When openning the debugging radius debugging information, it is found to have received authentication success message, but no authentication and accounting packets, which of the following reasons do probably cause such a phenomenon?

4. The following statements on MAC address, which is correct? (Multiple choice)

5. Layer 2 network running STP protocol, due to the topology changes, after re-electing the root port and the finger port, how long it takes to go into forwarding state by defaut?

6. 1.1.5 00-e0-fc-00-00-02 dynamic
State that the NIC on 00-e0-fc-00-00-02 this piece of equipment are configured with two different IP addresses.

7. In the ME60, when user use web authentication way, which command should not be included in forwarding region? 

8. In sup-vlan, it can't go through trunk link by default, but after permit-sup-vlan on the trunk link then it can pass.

9. On S9300, when joining the member interface to an Eth-Trunk, which type should be the member type?

10. In STP network environment, Alternate Port does not receive or forward any packets.

11. In Layer 2 switching network, when forwarding a frame, you can set the TTL value to prevent loops, thus to preventbroadcast storm.

12. RSTP protocol can complete the layer 2 environment's convergence much faster than STP protocol; it is because of less maintenance interface status, it can be directly from listening to forwarding without belonging to wait.
