Your on-premises identity provider (IdP) is being integrated with a cloud-based service. Federated authentication is available through the cloud-based service. Which two protocols from the list below could you utilize for the integration? (Select two.)
Please select 2 correct answers
Correct answer: SAML & OpenID Connect
One way to federate with a cloud-based service is to use SAML, which has been around for a long time and is widely accepted.

During an IT meeting, your colleague Karylle proposes that the only load balancer in place for the company's website ordering system has a single point of failure. She recommends configuring two load balancers, with only one in use at any one moment. What kind of load balancing setup does Karylle recommend?
Correct answer: Active-passive
Two load balancers are used in active-passive configurations, one of which is active. The second load balancer takes over when the active load balancer becomes unresponsive. The answers a, c, and d are incorrect. Load balancing algorithms such as round robin and least connections are not connected to fault tolerance when using multiple load balancers. Both load balancers are active at the same time and work cooperatively to distribute incoming traffic to back-end nodes in an active-active configuration. As a result, the right answer is b.
