11.
What are two purposes for using rate limits on
public and unrestricted APIs? (Choose two.)
to provide better service and response time
to all users (True)
to limit the number of passwords that a
client can have in making API requests
to
avoid a server overloading from too many requests at the same time (True)
to
ensure a client uses a multifactor authentication mechanism
to
limit the number of authorization requests per API call

manipulate data. (True)
It is a southbound API.
It supports a secure data transmission
between a remote user and an enterprise network.
It facilitates the configuration changes
from a network controller to end devices.
16.
