A systems administrator needs to configure SSO authentication in a hybrid cloud environment. Which of the following is the BEST technique to use?
Correct Answer: B
Federation is a type of authentication mechanism that allows users to access multiple systems or applications across different domains or organizations with a single login credential. Federation can help configure SSO authentication in a hybrid cloud environment, as it can enable seamless and secure access to cloud-based and on-premises resources using the same identity provider and authentication method. Federation can also improve user convenience, productivity, and security, as it can simplify the login process, reduce login errors, and enhance password management.

Correct Answer: D
Question 28
A cloud architect is reviewing four deployment options for a new application that will be hosted by a public cloud provider. The application must meet an SLA that allows for no more than five hours of downtime annually. The cloud architect is reviewing the SLAs for the services each option will use: Based on the information above, which of the following minimally complies with the SLA requirements?
Correct Answer: B
Explanation Option B is what minimally complies with the SLA (Service Level Agreement) requirements of allowing for no more than five hours of downtime annually for a new application that will be hosted by a public cloud provider. An SLA is a contract or agreement that defines the level of service or performance that a customer expects from a provider, such as availability, reliability, scalability, security, etc. An SLA can help to measure and monitor the quality and satisfaction of service or performance, as well as identify any penalties or rewards for meeting or failing to meet the SLA. Option B minimally complies with the SLA requirements by using services that have availability percentages that are equal to or higher than 99.95%, which translates to no more than five hours of downtime annually. Option B uses services such as: Compute: This is a service that provides computing resources such as servers, processors, memory, etc., to run applications or functions. Option B uses compute service with availability percentage of 99.95%, which means that it guarantees to be available for 99.95% of the time in a year, and allows for no more than five hours of downtime in a year. Storage: This is a service that provides storage resources such as disks, volumes, files, etc., to store data or information. Option B uses storage service with availability percentage of 99.99%, which means that it guarantees to be available for 99.99% of the time in a year, and allows for no more than one hour of downtime in a year. Database: This is a service that provides database resources such as tables, records, queries, etc., to store and retrieve data or information. Option B uses database service with availability percentage of 99.95%, which means that it guarantees to be available for 99.95% of the time in a year, and allows for no more than five hours of downtime in a year.
Question 29
A company needs to meet the security requirements for PII. Which of the following cloud service models allows the company to have the MOST control to meet the security requirements?
Correct Answer: D
Question 30
A cloud solutions architect has an environment that must only be accessed during work hours. Which of the following processes should be automated to best reduce cost?
Correct Answer: C
Explanation Shutting down the environment after work hours is the best process to automate to reduce cost, as it will stop incurring charges for the cloud resources that are not needed outside of work hours. Scaling, implementing access control, or blocking external access may still incur some costs for the cloud resources that are running or reserved, even if they are not fully utilized. Shutting down the environment can be automated using scripts, schedules, or triggers that can turn off or deallocate the cloud resources based on time or usage criteria12.
