• Question 124:

  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

  ---

  Explanation/Reference:

  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 125:

  You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.

  Which of the below option is NOT true for such a solution?

  A. If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance.
  B. Block volumes attached as read-only are configured as shareable by default.
  C. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.
  D. Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.
  C. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.

• Question 126:

  You are a cloud architect at a financial organization. The development team is tasked with creating a cloud native application to be hosted on Oracle Cloud Infrastructure (OCI). The development team has followed a microservices-based approach and created containerized images of the cloud-native application and pushed them to OCI Registry (OCIR).

  How can you deploy a load balanced application to your OCI Container Engine for Kubernetes (OKE) cluster using these images?

  A. Create a load balancer using the OCI load balancer service, add the load balancer service IP in the manifest file, add the location of the docker image to the manifest file, and deploy the manifest file.
  B. Create a named secret, add the secret to the manifest file, add the location of the docker image to the manifest file, add the service of type LoadBalancer in the manifest file, and deploy the manifest file.
  C. Create an auth token, add the auth token to the manifest file, add the location of the docker image to the manifest file, add the service of type LoadBalancer in the manifest file, and deploy the manifest file.
  D. Add the location of the docker image to the manifest file, deploy the manifest file. All applications are load-balanced by default in OKE
  A. Create a load balancer using the OCI load balancer service, add the load balancer service IP in the manifest file, add the location of the docker image to the manifest file, and deploy the manifest file.

• Question 127:

  A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) In two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is Intermittent due to the damages caused to the electrical grid.

  In this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints?

  A. Setup a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.
  B. Setup a hybrid network by launching aIGbpsFastConnect virtual circuit between your data center and OCI. Use OCI Object storage multipart upload tool to automate the migration of your data to OCI.
  C. Use multiple OCI Data Transfer Appliances to transfer data to OCI.
  D. Upload the data to OCI using OCI Object Storage multipart upload tool.
  E. Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.

  Explanation/Reference:

  Due to the network speed is not good enough and the connection is Intermittent due to the damages caused to the electrical grid Oracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. You have 2 Options of Data Transfer DISK-BASED DATA TRANSFER You send your data as files on encrypted commodity disk to an Oracle transfer site. Operators at the Oracle transfer site upload the files into your designated Object Storage bucket in your tenancy. APPLIANCE-BASED DATA TRANSFER you send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.

• Question 128:

  A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object

  Storage and created a policy as below:

  [ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes":

  "doc"] },

  "timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },

  { "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]

  1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }

  What will happen after this policy is applied?

  A. All objects with names starting with "doc" will be deleted after 5 days of object creation
  B. All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation
  C. All the objects having file extension ".doc" will be archived 5 days after object creation
  D. All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival
  A. All objects with names starting with "doc" will be deleted after 5 days of object creation

  ---

  Explanation/Reference:

  Object Lifecycle Management works by defining rules that instruct Object Storage to archive or delete objects on your behalf within a given bucket. A bucket's lifecycle rules are collectively known as an object lifecycle policy. You can use a rule to either archive or delete objects and specify the number of days until the specified action is taken.

  A rule that deletes an object always takes priority over a rule that would archive that same object.
