Question 7

OSPF supports area authentication and interface authentication. If both authentication modes are configured, interface authentication takes preference over area authentication.

A. FALSE B. TRUE

Correct Answer: B

Correct Answer: B

Question 9

In static LACP mode, the active interfaces selected by devices at both ends must be the same, otherwise, a LAG cannot be set up. You can specify one end as the Active side. Then the other end selects active interfaces based on the Active side.
So, in static LACP mode, how is the Active side be selected?

A. The end with a smaller MAC address is selected as the Active side. B. The end with a smaller LACP system priority functions as the Active side. If the two ends have the same LACP system priority, the end with a smaller MAC address functions as the Active side. C. The end with a lower LACP system priority functions as the Active side. If the two ends have the same LACP system priority, the end with a smaller MAC address functions as the Active side. D. The end with a higher LACP system priority functions as the Active side. If the two ends have the same LACP system priority, the end with a larger MAC address functions as the Active side.

Correct Answer: C

Question 10

Which three steps does a migration include? (Multiple Choice)

A. Delivery during the migration B. Snapshot before the migration C. Check after the migration D. Attendance after the migration

Correct Answer: A,B,C

Question 11

NFV and SDN depend on each other and must be used together.

A. FALSE B. TRUE

Correct Answer: A

Question 12

Which of the following statements regarding the static LACP mode are false?

A. If a high bandwidth of the link between two directly connected devices is required but the remote device does not support LACP, you can use the manual load balancing mode. B. In static LACP mode, a larger LACP priority of an interface indicates a higher priority of the interface and a high probability of becoming the active interface. C. When preemption is enabled and an active interface fails, the backup interface with a larger priority becomes the active interface after a delay. If preemption is disabled, the faulty interface cannot automatically become the active interface. D. The interface that forwards data is called the active interface, whereas the interface that does not forward data is called the inactive interface. The backup interface changes from inactive to active only when the active interface fails.

Correct Answer: B
