• Question 11:

  As a part of migration exercise for an existing on premises application to Oracle Cloud Infrastructure (OCT), yon ore required to transfer a 7 TB file to OCI Object Storage. You have decided to upload functionality of Object Storage. Which two statements are true?

  A. Active multipart upload can be checked by listing all parts that have been uploaded, however It Is not possible to list information for individual object part in an active multipart upload

  B. It is possible to spill this fileInto multiple parts using the APIs provided by Object Storage.

  C. It is possible to split this file into multiple parts using rclone tool provided by Object Storage.

  D. After initiating a multipart upload by making a CreateMultlPartUpload RESI API Call, the upload remains active until you explicitly commit it or abort.

  E. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order

  Correct Answer: AD

  You can check on an active multipart upload by listing all parts that have been uploaded. (You cannot list information for an individual object part in an active multipart upload.)

  After you finish creating object parts, initiate a multipart upload by making a CreateMultipartUpload REST API call. Provide the object name and any object metadata. Object Storage responds with a unique upload ID that you must include in any requests related to this multipart upload. Object Storage also marks the upload as active. The upload remains active until you explicitly commit it or abort it.

• Question 12:

  You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to

  archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).

  What is the most-effective mechanism to Implement this requirement?

  A. Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system

  B. Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.

  C. Setup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.

  D. Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard

  E. Setup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.

  Correct Answer: B

  Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier. you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and compressed or uncompressed ZIP or TAR archives. Storing secondary copies of data is an ideal use case for Storage Gateway.

• Question 13:

  You work for a bank as the lead Oracle Cloud Infrastructure architect. You designed a highly scalable solution for your company's banking application. The architecture includes a load balancer, application servers with autoscaling

  configuration based on CPU utilization, and an Autonomous Database with Transaction Processing workload type running in a Virtual Cloud Network (VCN).

  During the peak utilization period, the application users complain that the application runs slow.

  What are two possible reasons for the application running slow at times? (Choose two.)

  A. The VCN does not have a Network Security Group configured to allow traffic from the load balancer to all the application servers in the backend set.

  B. Instance pool in autoscaling configuration for the application servers did not scale out due to compartment quota breach of the VM shapes used by the application servers.

  C. The load balancer is not configured correctly to send traffic to all the listeners of the application servers in the backend set.

  D. Instance pool in autoscaling configuration for the Autonomous Database did not scale out due to misconfigured scaling policy.

  E. Instance pool in autoscaling configuration for the application servers did not scale out due to service limit breach of the VM shapes used by the application servers.

  Correct Answer: BE

• Question 15:

  A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the OCI FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this inter-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.

  What could be a potential reason for this issue?

  A. You need to first delete the OCI FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.

  B. Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.

  C. You need to remove all routes that point to the inter-cloud connection on both OCI and Azure before you can delete the circuit.

  D. You need to remove the Azure ExpressRoute Partner Service Key from the OCI FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.

  Correct Answer: A

• Question 16:

  Multiple departments In your company use a shared Oracle Cloud Infrastructure (OCI) tenancy to Implement their projects. You are in charge of managing the cost of OCI resources in the tenancy and need to obtain better Insights Into department's usage.

  Which three options can you implement together to accomplish this?

  A. Create a budget that matches your commitment amount and an alert at 100 percent of the forecast

  B. Set up a consolidated budget tracking lags to analyze costs in ,1 granular manner

  C. Set up different compartments for each department then track and analyze cost per compartment

  D. Use the billing cost tracking report to analyze costs

  E. Set up a tag default that automatically applies tags to all specified resources created In a compartment then use these tags for cost analysis.

  Correct Answer: ACE

  Explanation: budgets You can use budgets to track costs in your tenancy. After creating a budget for a compartment, you can set up alerts that will notify you if a budget is forecast to be exceeded or if spending surpasses a certain amount. OCI Cost Analysis Visualization tools Help understand spending patterns at a glance Filter costs by Date, Tags and Compartments Trend lines show how spending patterns are changing To use Cost Analysis you must be a member of the Administrators group

  

• Question 17:

  You notice that a majority of your Oracle Cloud Infrastructure (OCI) resources like compute instances, block volumes, and load balancers are not tagged. You have received a mandate from your CIO to add a predefined set of tags to identify owners for respective OCI resources. E.g. if Chris and Larry each create compute instances in a compartment, the instances that Chris creates include tags that contain his name as the value, while the instances that Larry creates have his name.

  Which option is the simplest way to implement this new tagging requirement?

  A. Create a default tag for each compartment, which ensure that appropriate tags are applied at the time of resource creation.

  B. Create an OCI Identity and Access Management policy requiring users to tag resources with their user name.

  C. Create an OCI Identity and Access Management policy to automatically tag a resource with the user name.
