  https://docs.cloud.oracle.com/en-us/iaas/Content/Resources/Assets/whitepapers/best-practices- for-dr-on-oci.pdf All three Data Guard configurations are fully supported on Oracle Cloud Infrastructure. However, because of a high risk of production outage, we don't recommend using the maximum protection mode for your Data Guard configuration. We recommend using the maximum availability mode in SYNC mode between two availability domains (same region), and using the maximum availability mode in ASYNC mode between two regions. This architecture provides you the best RTO and RPO without causing any data loss. We recommend building this architecture in daisy-chain mode: the primary database ships redo logs to the first standby database in another availability domain in SYNC mode, and then the first standby database ships the redo logs to another region in ASYNC mode. This method ensures that your primary database is not doing the double work of shipping redo logs, which can cause performance impact on a production workload.

  

  This configuration offers the following benefits:

  No data loss within a region.

  No overhead on the production database to maintain standbys in another region. Option to configure lagging on the DR site if needed for business reasons. Option to configure multiple standbys in different regions without any additional

  overhead on the production database. A typical use case is a CDN application Bottom of Form

• Question 93:

  A global media organization is working on a project which lets users upload their videos on their site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and don't want to worry about underlying infrastructure for high-availability, scalability, security and monitoring. Which OCI services should you recommend for this project?

  A. Use OCI Events service for triggering automatic processing of video, Oracle Container Engine for Kubernetes (OKE) and OCI Digital Assistant
  B. Use Oracle Container Engine for Kubernetes (OKE) for deployment of Al Code, OCI Notifications and Object Storage
  C. Use OCI Resource Manager to manage the underlying infrastructure, OCI Functions and OCI Events service.
  D. Use Object Storage for storing videos, OCI Events service and OCI Functions
  D. Use Object Storage for storing videos, OCI Events service and OCI Functions

  Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a- Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs. The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution. You can create automation based on state changes for your Oracle Cloud Infrastructure resources by using event types, rules, and actions. When the function is executing inside the container, the function can read from and write to other resources and services running in the same subnet (for example, Database as a Service). The function can also read from and write to other shared resources (for example, Object Storage), and other Oracle Cloud Services.

• Question 94:

  Which of the following is NOT a good use case for the Oracle Cloud Infrastructure (OCI) Streaming service?

  A. Meeting compliance requirements for data to remain unchanged over a long time, so that it can be retrieved for audit purposes.
  B. Messaging with a pull-based communication model and the ability to feed multiple consumers with the same data independently.
  C. Ingesting metric and log data to help make critical operational data more quickly available for indexing, analysis, and visualization.
  D. Providing a unified entry point for cloud components to report their life cycle events for audit, accounting, and related activities.
  A. Meeting compliance requirements for data to remain unchanged over a long time, so that it can be retrieved for audit purposes.

• Question 95:

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

• Question 96:

  Which of the following is NOT a good use case for using the functionality available in the Oracle Cloud Infrastructure (OCI) Events service?

  A. Publish all events in a specific compartment to Oracle Streaming service for later analysis.
  B. Triggers Function using Oracle Functions when new files are uploaded in an OCI Object Storage bucket.
  C. Publish a notification when long lived tasks complete, such as OCI Autonomous Database backup completion.
  D. Capture Monitoring Alarms and invoke Autoscaling of compute instances.
  E. Trigger a notification when a function completes its execution.
  D. Capture Monitoring Alarms and invoke Autoscaling of compute instances.

• Question 97:

  An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload. Which of the following needs to be considered while configuring auto scaling? Choose two

  A. Enabling auto scaling does not change the concurrency and parallelism settings
  B. Auto scaling also scales IO throughput linearly along with CPU
  C. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling
  D. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs
  A. Enabling auto scaling does not change the concurrency and parallelism settings
  B. Auto scaling also scales IO throughput linearly along with CPU

  ---

  Auto scaling is enabled by default when you create an Autonomous Database instance or you can use Scale Up/Down on the Oracle Cloud Infrastructure console to enable or disable auto scaling. With auto scaling enabled the database can use up to three times more CPU and IO resources than specified by the number of OCPUs currently shown in the Scale Up/Down dialog. When auto scaling is enabled, if your workload requires additional CPU and IO resources the database automatically uses the resources without any manual intervention required. Enabling auto scaling does not change the concurrency and parallelism settings for the predefined services IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs.

• Question 98:

  You are developing a Serverless function for your company's IoT project. This function should access Oracle Cloud Infrastructure (OCI) Object Storage to store some files. You choose Oracle Functions to deploy this function on OCI. However, your security team doesn't allow you to carry any API Token or RSA Key to authenticate the function against the OCI API to access the Object Storage. What should you do to get this function to access OCI Object Storage without carrying any static authentication files? (Choose the best answer.)

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A
