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 an OCI load Balancer and distribute the traffic between OCI 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 OCI Traffic management service with failover steering policy 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.

You notice that a majority of your Oracle Cloud Infrastructure (OCI) resources like compute instances, block volumes, and load balancers are not tagged. You have received a mandate from your CIO to add a predefined set of tags to identify owners for respective OCI resources. E.g. if Chris and Larry each create compute instances in a compartment, the instances that Chris creates include tags that contain his name as the value, while the instances that Larry creates have his name.
Which option is the simplest way to implement this new tagging requirement?

• A.Create an OCI Identity and Access Management policy to automatically tag a resource with the user name.
• B.Create a default tag for each compartment, which ensure that appropriate tags are applied at the time of resource creation.
• C.Create an OCI Identity and Access Management policy requiring users to tag resources with their user name.
• D.Create tag variables to automatically tag a resource with the user name.

You are working on the migration of the web application infrastructure of your company from on-premises to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?

• A.DNS changes propagate fast enough that it is not necessary to take any action.
• B.Increase the TTL of the DNS records after the switch.
• C.Increase the TTL of the DNS records before the switch.
• D.Reduce the TTL of the DNS records before the switch.
• E.Reduce the TTL of the DNS records after the switch.
