Which Oracle Cloud Infrastructure (OCI) services would meet these requirements?

Ans: OCI Object Storage, OCI Events service and OCI Functions.

3. An online gaming application is deployed to multiple Availability Domains in the Oracle Cloud Infrastructure (OCI) us-ashburn-1 region. Considering the high volume of traffic that the gaming application handles, the company has hired you to ensure that the data stored by the application is scalable, highly available, and disaster resilient. In the event of failure, the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) must be less than 2 hours.

During the day 1 of promotional period it was observed that the application is running slow and company’s hotline is flooded with complaints.

What could be two possible reasons for this situation?

Ans: Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.

     The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.

So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.

Which of the below option is NOT true for such a solution?

Ans: You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance’s storage intact.

27. An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to Oracle Cloud Infrastructure (OCI). One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration.

They cannot afford to have any application down time when they do the migration.

What is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?

What should be the cause ?

Ans: The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

Which two options are expensive or impractical ways to improve the application response times?

Ans: Scale up CPU core count and memory during peak times. 

       Identify the maximum CPU capacity needed for peak times and scale the CPU core count for the  ATP-S database to that number. ATP-S will scale the CPU core count down when not needed.

 

46. You are designing the network infrastructure for an application consisting of a web server (server-1) and a Domain Name Server (server-2) running in two different subnets inside the same Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access server-1 from the internet and server-2 from your customer’s on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit.

How should you design your routing configuration to meet these requirements?  

Ans: Configure two routing tables: first one with a route to internet via an Internet gateway; associate this route table to the subnet containing server-1.Configure the second route table to propagate specific routes to the on-premises network via a Dynamic Routing Gateway; associate this route table to subnet containing server-2.
