• Question 51:

  An automobile company wants to deploy their CRM application for Oracle Database on Oracle Cloud Infrastructure (OC1) DB Systems for one of major clients. In compliance with the Business Continuity Program of the client, they need to provide a Recovery Point objective (RPO) of 24 hours and a Recovery time objective (RTO) of 24 hours and Recovery Time Objective (RTO) of 1 hour. The CRM application should be available oven in me event that an entire on Region is down. Which approach Is the most suitable and cost effective configuration for this scenario?

  A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
  B. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.
  C. Deploy a 1 node VM Oracle database in one region. Manual Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region, If the primary OCI region is unavailable launch a new 1 new VM Database in the other OCI region restore the production database from the backup.
  D. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region Oracle GoldenGate.
  A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.

  ---

  You can configure the Autonomous Database instance as a target database for Oracle GoldenGate. But You can't set up Oracle Autonomous Database as a source database for Oracle GoldenGate. Recovery Point objective (RPO) of 24 hours and Recovery Time Objective (RTO) of 1 hour

  -

  To provision new VM and restore the production database from the backup on object storage, will exceed the RTO 1 hour

  -

  You can create the standby DB system in a different availability domain from the primary DB system for availability and disaster recovery purposes. With Data Guard and switchover/failover can meet RTO 1 hour.

  -

  RAC Database is not required in this solution. Standalone will be most suitable and cost effective

• Question 52:

  A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They

  have decided to use both containers and servers technologies to run these application instances.

  Which option should you recommend to build this new platform?

  A. Install a kubernetes cluster on OCI and use OCI event service.
  B. Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.
  C. Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
  D. Use OCI functions, OCI object storage and OCI event service.
  B. Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.

  Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a- Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.

  

  Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.

• Question 53:

  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.
  D. Create tag variables to automatically tag a resource with the user name.
  D. Create tag variables to automatically tag a resource with the user name.

• Question 57:

  You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down. What should you do to help maintain write performance and protect against NVMe devices failure.

  A. NVMe drive have built in capability to recover themself so no other actions are required
  B. Configure RAID 6 for NVMe devices.
  C. Configure RAID 1 for NVMe devices.
  D. Configure RAID 10 for NVMe devices.
  D. Configure RAID 10 for NVMe devices.

  ---

  VM.DeselO2.24 compute instance include locally attached NVMe devices. These devices provide extremely low latency, high performance block storage that is ideal for big data, OLTP, and any other workload that can benefit from high-performance block storage. A protected RAID array is the most recommended way to protect against an NVMe device failure. There are three RAID levels that can be used for the majority of workloads: RAID 1: An exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks RAID 10: Stripes data across multiple mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved RAID 6: Block-level striping with two parity blocks distributed across all member disks If you need the best possible performance and can sacrifice some of your available space, then RAID 10 array is an option.

• Question 58:

  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

  ---

  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.

• Question 60:

  You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist

  in different compartments within your tenancy. Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.

  What could be the cause?

  A. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
  B. You are exceeding your volume group backup quota configured.
  C. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
  D. A compute instance with multiple block volumes attached cannot move when a compartment is moved.
  A. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
