質問 3：
You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?
A. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.
B. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.
C. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.
D. The load balancerperformed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.
正解：C

質問 4：
You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing.
What would you do to identify the reason for this missing resource?
A. Create a serial console connection to the DB System that does not appear in the management console.
Connect to the serial console connection, and then review the system logs under/var/log/messages.
B. Navigate to the Audit console and search the previous 24 hours for all theGETrequest actions to get a list ofevery event that occurred in the past 24 hours.
C. View the service limits associated with your account to ensure that you have not exceeded the allowable number of DB Systems in your tenancy.
D. Navigate to the Auditconsole and search the previous 24 hours for allDELETErequest actions to get a list of any resource that was deleted in the past 24 hours.

質問 6：
Which two are true for achieving High Availability on Oracle Cloud Infrastructure? (Choose two.)
A. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
B. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
C. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highlyavailable.
D. Store your database across multiple regions so that half of the data resides in one region and the other half resides in another region.
E. Distribute your application servers across all Availability Domains within a region.
正解：A,E

質問 7：
You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?
A. Terminate the VM.Standard2.24 instance and do not preserve the boot volume
B. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes
C. Terminate the VM.Standard2.24 instance and preserve the boot volume
D. Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks
正解：A,B
