Oracle 1Z0-997-20 問題集

質問 1：
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 and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe application from on-premises to OCI.
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 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.
正解：B

質問 2：
A customer has a Virtual Machine instance running in their Oracle Cloud Infrastructure tenancy. They realized that they wrongly picked a smaller shape for their compute instance. They are reaching out to you to help them fix the issue.
Which of the below options is best recommended to suggest to the customer?
A. Change the shape of the virtual machine instance using the Change Shape feature available in the console.
B. Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.
C. OCI doesn't allow such an operation.
D. Delete the running instance and spin up a new instance with the desired shape.

質問 3：
You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web-based attacks across the internet and asked what you can do to add a higher level of security to the website.
How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)
A. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.
B. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.
C. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.
D. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.
正解：B

質問 4：
You are the Solution Architect that designed this Oracle Cloud Infrastructure (OCI) compartment layout for your organization:

The development team has deployed quite a few instances under 'Compute' Compartment and the operations team needs to list the Instances under the same compartment for their testing. Both teams, development and operations are part of a group called 'Eng-group' You have been looking for an option to allow the operations team to list the instances without access any confidential information or metadata of resources.
Which IAM policy should you write based on these requirements?
A. Allow group Eng-group to read instance-family in compartment Compute and attach the policy to 'Engineering' Compartment.
B. Allow group Eng-group to inspect instance-family in compartment Dev-Team:Compute and attach the policy to 'Engineering' Compartment
C. Allow group Eng-group to read instance-family in compartment Dev-Team-.Compute and attach the policy to'Dev-Team'
D. Allow group Eng-group to inspect instance-family in compartment Dev-Team: Compute and attach the policy to 'SysTest Team' Compartment

Which method of database migration should you choose so that the application has minimal impact? (Choose the best answer.)
A. Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.
B. 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.
C. Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.
D. Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.
