Question 1

You have been asked to create a mobile application which will be used for submitting orders by users of apopular E-Commerce site. The application is built to work with Autonomous Transaction Processing -Serverless (ATP-S) databaseas the backend and HTML5 on Oracle Application Express as the front end.During the peak usage of the application you notice that the application response time is very slow. ATP-Sdatabase is deployed with 3 CPU cores and 1 TB of memory.Which two optionsare expensive or impractical ways to improve the application response times?

Options :

A : Identify the maximum memory capacity needed for peak times and scale the memory for the ATP-S database to that number. ATP-S will scale the memory down when not needed.

B : Usethe Machine Learning (ML) feature of the ATP-S database iteratively to tune the SQL queries used by the application

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

D : Enable auto scaling for CPU cores on ATP-S database.

E : 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.

Answer: A,C

Question 2

A data analytics company has been building Its now generation big data and analytics platform on OracleCloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their bigdata applications require such as high throughput to compute nodes with low latency file operations inaddition, their data needs to be stored redundantly across multiple nodes In a single availability domain andallows concurrent connections from multiple compute Instances hosted on multiple availability domains.Which OCI storage service can you use to meet i his requirement?

Options :

A : Object Storage

B : File System Storage

C : Archive storage

D : Block Volume

Answer: B

Question 3

A retailer bank is currently hosting their mission critical customer application on-premises. The applicationhas a standard 3 tier architecture -4 application servers process the incoming traffic and store application datain an Oracle Exadata Database Server. The bank has recently has service disruption to other inter applicationsto they are looking to avoid this issue for their mission critical Customer Application.Which Oracle Cloud Infrastructure services should you recommend as part of the DR solution?

Options :

A : OCI DNS Service' Public Load Balancer, Oracle Database Cloud Backup Service, ObjectStorage Service, Oracle Bare Metal Cloud Service, Oracle Bare Metal Cloud Service with GoldenGate, OCI Container Engines for Kubernetes, Oracle IPSec VPN

B : OCI Traffic Management, Private Load Balancer, Compute instances distributed across multiple Availability Domains and/or Fault Domains, Exadata Cloud Service with Data Guard, Oracle FastConnect, Object Storage, Database Cloud backup module

C : OCI Traffic Management, Public toad Balancer, Compute Instances distributed across multiple Availability Domains and/or Vault domains. Exadata Cloud Service with Data Guard, Oracle FastConnect, Object Storage, Database cloud backup module

D : OCI DNS Service, Load Balancer as a service using Public Load Balancer distributing traffic Compute Instance across multiple regions, Oracle RAC Database using Virtual Machines, Remote Peering connecting two VCNs in different regions. Exadata Cloud Service with GoldenGate FastConnect, Object Storage, Database Cloud backup module.

Answer: C

Question 4

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?

Options :

A : Use OCI Traffic management service with failover steering policy 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 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

Question 5

A developer is using Oracle Functions to deploy her code as part of an event-driven solution in Oracle Cloud Infrastructure (OCI). When sheinvokes her function, Oracle Functions returns a FunctionlnvokelmageNotAvailable message and a 502 error 1z0-997-21-page106-image22 Which of the following options is NOT a plausible reason for this error?

Options :

A : Missing or invalid IAM policy to give Oracle Functions read access to images stored for functions in repositories in OCI Registry.

B : The function does not exist in the specified location in OCI Registry.

C : The VCN being used does not have an internet gateway or a service gateway configured for Oracle Functions to be able toaccess OCI Registry.

D : OCI Events service rule is not configured with the correct location of the function in OCI Registry.
