    B. Turn off automated backups from the eCommerce database, implement Oracle Data Guard with the Standby database deployed on another availability domain, take backups from the standby database.
    C. Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure bi-directional replication from the eCommerce Database over to the new VM RAC database using GoldenGate. Take backups from the new VM RAC database.
    D. Turn off automatic backups from the eCommerce database, implement Oracle Active Data Guard with the standby database deployed on another availability domain, and take backups from the standby database.

  • Question 62:

    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?

    A. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Import the on-premises database to OCI VM DB Systems using Oracle Data Pump and then enable automatic backups.
    B. Launch a compute instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.
    C. Launch a compute instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.
    D. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled.

  • Question 63:

    A digital marketing company is planning to host a website on Oracle Cloud Infrastructure (OCI) and leverage OCI Container Engine for Kubernetes (OKE). The web server will make API calls to access OCI Object Storage to store all images uploaded by users. For security purposes, your manager instructed you to ensure that the credentials used by the web server to allow access not stored locally on the compute instance. What solution results in an Implementation with the least effort for this scenario?

    A. Configure the credentials using Instance Principal to allow the web server to make API calls to OCl Object Storage
    B. Configure the credentials using OCI Registry (OC1R) which will automatically connect with OKE allowing the web server to make API calls to OCI Object Storage.
    C. Configure the credentials to use Transparent Data Encryption (TDE) which will automatically allow the web server to make API calls to OCl Object Storage.
    D. Configure the credentials using OCI Key Management to allow an instance to make API calls and grant access to OCl Object Storage.

  • Question 64:

    You want to automate the processing of new Image files to generate thumbnails. the expected rate is 10 new files every hour. Which of the following is the most cost effective option to meet this requirement in Oracle Cloud Infrastructure (OCI)?

    A. Upload files to an OCI Object storage bucket. Every time a file is uploaded, an event is emitted. Write a rule to filter these events with an action to trigger a function in Oracle Functions. The function processes the image in the file and stores the thumbnails back in an Object storage bucket.
    B. Upload files to an OCI Object storage bucket. Every time a file is uploaded, trigger an event with an action to provision a compute instance with a cloud-init script to access the file, process it and store it back in an Object storage bucket. Terminate the instance using Autoscaling policy after the processing is finished.
    C. Build a web application to ingest the files and save them to a NoSQL Database. Configure OCI Events service to trigger a notification using Oracle Notification Service (ONS). ONS invokes a custom application to process the image files to generate thumbnails. Store thumbnails in a NoSQL Database table.
    D. Upload all files to an Oracle Streaming Service (OSS) stream. Set up a cron job to invoke a function in Oracle Functions to fetch data from the stream. Invoke another function to process the image files and generate thumbnails. Store thumbnails in another OSS stream.

  • Question 65:

    An upcoming e-commerce company has deployed their online shopping application on OCI. The application was deployed on compute instances with autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. 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?

    A. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation
    B. As part of autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change
    C. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.
    D. The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling

  • Question 66:

    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. Which Disaster Recovery strategy should be used to achieve the RTO and RPO requirements in the event of a system failure?

    A. Configure hourly block volumes backups using the OCI Command Line Interface (CLI).
    B. Create a user defined backup policy with a schedule of generating daily backups for block volumes.
    C. Configure hourly block volumes backups through the OCI Storage Gateway service.
    D. Create a user defined backup policy with a schedule of generating hourly backups for block volumes.

  • Question 67:

    You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu- frankfurt-1 region. The compute instances

    do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have

    enabled monitoring on the instances.

    What could be wrong in this situation?

    A. You need to assign a reserved public IP address to the compute instances.
    B. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.
    C. Autoscaling only works for instances with public IP addresses.
    D. Autoscaling only works with single availability domains.

  • Question 68:

    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?

    A. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagates specific routes for the on-premises network via a Dynamic Routing Gateway. Don't associate this routing table with any of the subnets in the VCN.
    B. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagate specific routes to the on-premises network via a Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
    C. 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.
    D. Configure two routing tables that have rules to route all traffic via a Dynamic Routing Gateway. Associate the two routing tables with all the VCN subnets.

  • Question 69:

    A developer is using Oracle Functions to deploy her code as part of an event-driven solution in Oracle Cloud Infrastructure (OCI). When she invokes her function, Oracle Functions returns a FunctionlnvokelmageNotAvailable message and a 502 error:

    Which of the following options is NOT a plausible reason for this error?

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

  • Question 70:

    Your customer recently ordered for a 1-Gbps Fast Connect connection In ap-tokyo-1 region of Oracle Cloud Infrastructure (OCI). They will us this to one Virtual cloud Network (VCN) in their production (OC1) tenancy and VCN In their development OC1 tenancy As a Solution Architect, how should yon configure and architect the connectivity between on premises and VCNs In OCI?

    A. Create two private virtual circuits on the FastConnect link. Create two Dynamic Routing Gateways, one for each VCNs. Attach the virtual circuits to the dynamic routing gateways.
    B. You cannot achieve connectivity using single FastConnect link as the production and the development VCNs-are in separate tenancies. Request one more FastConnect connection.
    C. Create a single private virtual circuit over FastConnect and attach fastConnect to either of the VCN's Dynamic Routing Gateway. Use Remote Peering to peer production and development VCNs.
    D. Create a hub-VCN that uses Dynamic Routing Gateway (DRG) to communicate with on-premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective local Peering Gateway (LPG)
