Which three statements about nxapi_auth are true? (Choose three.)

A. Use of nxapi_auth is optional. This feature can be disabled to reduce authentication time and support large number of API calls.
B. After the first successful authentication, the username and password are used with the session cookie to bypass performing the full authentication process again.
C. Expiration time of the nxapi_auth cookie can be changed up to the maximum of 1200 seconds.
D. After the first successful authentication, the username and password are NOT included in subsequent NX-API requests that are sent to the device.
E. NX-API performs authentication through a programmable authentication module on the switch. Using cookies reduces the number of PAM authentications, which reduces the load on the PAM.
F. The nxapi_auth cookie expires in 600 seconds.
