OCI architect 2021 professional 1z0-997-21 dumps







A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements.

In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI.

How can these requirements be met with the LEAST amount of effort?

A.      Use OCI Traffic management service with failover steering policy and distribute the traffic between OC1 and on premises infrastructure.

B.      Use OCI Traffic management service with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure.

C.      Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure.

D.      Use VPN connectivity between on premises Infrastructure and OCI and create routing tables to distribute the traffic between them.

Answer

B

To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, evenly spread across two availability domains in the us-ashburn-1 region; Load Balancer is used to deliver the traffic across instances.

After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional VM.Standard2.8 instances. You register the two VM.Standard2.8 instances with your Load Balancer Backend set and quickly find that the VM.Standard 2.8 instances are now running at 100% of CPU utilization but the BM.Standard 2.52 instances have significant CPU capacity that's unuse

Which option is the most cost effective and uses instances capacity most effectively? (Choose the best answer.)

A.      Configure Autoscaling instance pool with LoadBalancerto add up to 3 more BM.Standard2.52 instances when triggered. Shut off VM.Standard2.8 instances.

B.      Configure Load Balancer with two VM.Standard 2.8 instances and use Autoscaling instance pool to add up to two additional VM.Standard 2.8 instances. Shut off BM.Standard2.52 instances.

C.      Route traffic to BM.Standard2.52 and VM.Standard 2.8 instances directly using DNS and Health Checks. Shut off the Load Balancer.

D.      Configure your Load Balancer with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.

It has multiple endpoints that needs to be exposed to the public internet. What is the most cost-effective way to expose multiple application endpoints without adding complexity to the application?
