• Question 121:

  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 all files to an Oracle Streaming Service (OSS) stream. Setup 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.

  B. 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.

  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 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.

  Correct Answer: B

• Question 122:

  A retail company has several on-premises data centers which span multiple geographical locations. They plan to move some of their applications from on-premises data centers to Oracle Cloud Infrastructure (OCI). For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on-premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI.

  Which option should you recommend to provide the highest level of redundancy?

  A. Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required

  B. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location

  C. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.

  D. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure

  E. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective

  Correct Answer: B

  If your data centers span multiple geographical locations, we recommend using a broad CIDR (0.0.0.0/0) as a static route in addition to the CIDR of the specific geographical location. This broad CIDR provides high availability and flexibility to your network design. For instance, the following diagram shows two networks in separate geographical areas that each connect to Oracle Cloud Infrastructure. Each area has a single on-premises router, so two IPSec VPN connections can be created. Note that each IPSec VPN connection has two static routes: one for the CIDR of the particular geographical area, and a broad 0.0.0.0/0 static route.

  

• Question 123:

  You work for a large bank where security and compliance are critical. As part of the security overview meeting, your company decided to minimize the installation of local tools on your laptop. You have been running Ansible and kubectl to spin up Oracle Container Engine for Kubernetes (OKE) clusters and deployed your application.

  For authentication, you are using an Oracle Cloud Infrastructure (OCI) CLI config file that contains OCIDs, Fingerprint, and a locally stored PEM file. Your security team doesn't want you to store any local API key and certificate, or any other local tools.

  Which two actions should you perform to spin up the OKE cluster and interact with it? (Choose two.)

  A. Create a developer workstation on OCI. Install Ansible and kubectl on it. Use resource principal to authenticate against OCI API and create the OKE Cluster.

  B. Develop your own code using OCI SDK to deploy the OKE cluster.

  C. Work on OCI Cloud Shell to use built-in Ansible and kubectl to deploy the OKE cluster. Use OCI_CLI_AUTH=instance_obo_user environment variable to authenticate using built- in token.

  D. Work on OCI Cloud Shell to use built-in Ansible and kubectl to deploy the OKE cluster. Bring in your own config file and certificate to authenticate against OCI API.

  E. Create a developer workstation on OCI. Install Ansible and kubectl on it. Use instance principal to authenticate against OCI API and create the OKE Cluster.

• Question 125:

  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

  Correct Answer: A

  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.
