Oracle Cloud Infrastructure 2020 Architect Professional (1Z0-997-20) Free Practice Test

Question 1

You work for a large bank where your main application is a payment processing gateway API. You deployed the application on Oracle Container Engine for Kubernetes (OKE) and used API Gateway with several policies to control the access of the API endpoint.
However, your customers are complaining about the unavailability of the API endpoint. Upon checking, you noticed that the Gateway URL is throwing Service Unavailable error. You need to check the backend latency and backend responses when this error started last night.
What should you do to get this data? (Choose the best answer.)

A. Go to Developer Services and click on API Gateway. Go to the detail page of the gateway and select Metrics. Change the Start and End time to filter the metrics.

B. Go to Monitoring and click on Service Metrics. Choose the Metric Namespace as oci_apigateway. Change the Start and End time accordingly. Add a Dimension and select httpStatusCode: 503. Check the backend latency and backend responses metric.

C. Go to Governance Menu and click on Audit to see the Audit log for the API Gateway. Filter it using Start and End date with a 503 response status.

D. Check with the application owner and search the log file for the container to get the metrics from the log file.

Question 3

To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, event spread across two availability domains in the us-asburn-1 region: LoadBalancer is used to deliver the traffic across instances.
After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional VM.Standard2.8 instances.
You register the two VM. Standard2. 8 Instances with your load Balancer Backend sot and quickly find that the VM Standard2.8 Instances running at 100% of CPU utilization but the BM.Standard2 .52 instances have significant CPU capacity that's unused.
Which option is the most cost effective and uses instances capacity most effectively?

A. Configure your Load Balance, with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.

B. Configure LoadBalancer with two VM Standard2.8 instances and use Autoscalling Instant pool to add up to two additional VM instances. Shut off BM.Standard2.52 instances.

C. Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 Instances when triggered. Shut off VM.Standard2.8 instances.

D. Route traffic to BM.Standard2.52 and VM Standard2.8 instances directly using DNS and Health Checks. Shut off the load Balances.

Question 4

You are working as a security consultant with a global insurance organization which is using Microsoft Azure Active Directory as an identity provider to manage user login/passwords. When a user logs in to Oracle Cloud Infrastructure (OCI) console, it should get authenticated by Azure AD.
Which set of steps are required to be configured in OCI to meet this requirement?

A. Setup Azure AD as an Enterprise Application, configure OCI for single sign-on, map Azure AD groups to OCI groups, set up the IAM policies to govern access to Azure AD groups.

B. Setup Azure AD as an Identity Provider, import users and groups from Azure AD to OCI, set up IAM policies to govern access to Azure AD groups.

C. Setup Azure AD as an Enterprise Application, map Azure AD users, groups and policies to OCI groups and users.

D. Setup Azure AD as an Identity Provider, map Azure AD groups to OCI groups, set up the IAM policies to govern access to Azure AD groups.

Correct Answer: D

Question 5

Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle Database and both the application and database servers run on Oracle Linux version 7. The application server is WebLogic server running on multiple 4-core servers and the database is deployed as an Oracle Database Enterprise Edition RAC database on 2 servers (4-cores each).
Which method of database migration should you choose so that the application has minimal impact? (Choose the best answer.)

A. Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.

B. Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.

C. Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.

D. Deploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.

Question 6

A customer is in a process of shifting their web based Sales application from their own data center located in US West to OCI India West (Mumbai) region. They want to do it in a controlled manner and initially only 1% of the traffic will be steered to the servers in OCI. After verification of everything is working as expected, the company is gradually planning to increase the ratio until they are comfortable with fully migrating all traffic to OCI.
Which of the following solution can be used in this situation?

A. OCI DNS and Traffic Management with Geolocation Steering policy

B. OCI DNS and OCI Load Balancer Service

C. OCI DNS and Traffic Management with Failover Steering policy

D. OCI DNS and Traffic Management with Load Balancer Steering policy

Question 7

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. Auto scaling also scales IO throughput linearly along with CPU

B. Enabling auto scaling does not change the concurrency and parallelism settings

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

Question 8

You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.
You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user.
