Q12. You are a migration architect responsible for migrating 100 TB of on-premises data to Oracle Cloud Infrastructure (OCI). Because of limited bandwidth and security concerns, transferring the data over the public Internet is not feasible. Which OCI service would you recommend to efficiently transfer the large volume of on-premises data to OCI while ensuring data security?

Snowball

Data Transfer Service

Data Integration

Storage Gateway

Data Transfer Service in OCI is specifically designed for efficiently transferring large volumes of data to OCI while ensuring data security. It provides high-speed data transfer over dedicated network connections, making it the ideal choice for migrating 100 TB of on-premises data to OCI.

Q13. In Oracle Cloud Infrastructure (OCI), how are Security Lists different from Network Security Groups (NSGs) in terms of their functionality and application?

Security Lists offer more advanced features such as intrusion detection and prevention, whereas NSGs focus solely on packet filtering and routing

NSGs are primarily used for inbound traffic control, while Security Lists are exclusively utilized for outbound traffic control within a subnet

A Security List defines a set of security rules that applies to all the VNICs in a subnet whereas a Network Security Group lets you define a set of security rules that applies to a group of VNICs in a Virtual Cloud Network (VCN)

Security Lists and NSGs are identical in functionality but differ only in naming conventions based on the OCI region where they are deployed

A Security List in OCI defines a set of security rules that apply to all the Virtual Network Interface Cards (VNICs) within a subnet, while a Network Security Group (NSG) allows you to define a set of security rules that apply to a specific group of VNICs within a Virtual Cloud Network (VCN).

Q14. What is the primary purpose of the Oracle Cloud Balancer or OCI Native Ingress Controller during the implementation phase of Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) workloads?

Expose running workloads internally and externally

Conduct comprehensive testing and monitor performance metrics

Gradually shift traffic from the source environment to OKE

Efficiently manage packages with Helm charts

Exposing running workloads internally and externally is the main purpose of the Oracle Cloud Balancer or OCI Native Ingress Controller during the implementation phase of OKE workloads. These tools help manage incoming traffic and route it to the appropriate services within the Kubernetes cluster.

Q15. What is a valid purpose for creating multiple Migration Plans for each Migration Project in Oracle Cloud Migrations?

To create a backup from the existing Migration Plan, as a precautionary measure against misconfiguration

To validate different compute shapes for each VM ensuring the most effective configuration can be chosen

To incrementally increase the allocated budget for each Migration Plan

To accelerate the migration task by assigning each Migration Plan to the respective migration team

Creating multiple Migration Plans for each Migration Project allows for the validation of different compute shapes for each VM. This ensures that the most effective configuration can be chosen based on the specific requirements of each workload, leading to optimized performance and resource utilization in the Oracle Cloud Migration.

Q16. What is the primary function of the Data Transfer Utility provided by Oracle Cloud Infrastructure (OCI)?

To automate data replication between OCI compute instances

To transfer data between OCI regions

To transfer data between different OCI Compartments

To prepare transfer disks for data shipment to Oracle

The Data Transfer Utility is primarily used to prepare transfer disks for data shipment to Oracle’s data centers.

Q17. Which two statements are true about physical migration of Oracle databases?

You can run a cloud premigration advisor tool to perform compatibility check prior to migration

During physical migration, copies of database objects are created in dumps

Source and Target database versions must be the same

You cannot filter and migrate database objects

You cannot achieve zero or near-zero downtime with physical migration

Running the cloud premigration advisor tool is a recommended practice before migration to perform a compatibility check and identify any potential issues. Also, for physical migration, the source and target database versions must be the same to ensure compatibility.

Q18. Which is NOT a valid connectivity model in Oracle Cloud Infrastructure (OCI) FastConnect?

FastConnect: With a Third-Party Provider

FastConnect: With an Oracle Partner

FastConnect: Colocation with Oracle

FastConnect: Direct-to-Cloud

FastConnect: Direct-to-Cloud is not a valid connectivity model in Oracle Cloud Infrastructure (OCI) FastConnect. This option does not align with the available methods for establishing connectivity through FastConnect.

Q19. Your organization is in the stage of planning a migration of on-premises workloads to Oracle Cloud Infrastructure (OCI) using Oracle Cloud Migrations (OCM). As a migration architect, you are setting up the service to discover workloads. The initial step in this process involves the creation of Asset Source. Which statement accurately describes Asset Source?

Is a remote virtual appliance deployed in the on-premises environment for discovery purposes

Represents a repository within OCI where migrated assets are temporarily stored before being deployed into their final configuration

Consists of credentials and connectivity details required by OCM to access and communicate with the on-premises environment

Provides real-time cost analysis and optimization recommendations for assets during the migration planning phase

Asset Source in OCM consists of the necessary credentials and connectivity details that allow OCM to access and communicate with the on-premises environment. This information is crucial for OCM to discover and assess the workloads that need to be migrated to OCI.

Q20. Which option best describes the term Inventory Asset in the context of Oracle Cloud Migrations (OCM) service?

Virtual Machines that have been specifically selected to migrate to OCI within the OCM UI

The entire on-premises environment that is subject to discovery and analysis by OCM

Virtual Machines that have been automatically discovered and listed in the OCM UI

An OCI Compute instance representing the migrated on-premises asset in the OCM UI

Virtual Machines that have been specifically selected to migrate to OCI within the OCM UI are considered Inventory Assets. These assets are the ones that will undergo the migration process to Oracle Cloud Infrastructure as part of the OCM service.

Q21. Which statement accurately describes the routing mechanism within a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI)?

Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities

A subnet in a VCN is associated with a single route table, dictating how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed

If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet

VCN local routing necessitates manual configuration of route rules to facilitate infrastructure communication

In Oracle Cloud Infrastructure (OCI), a subnet in a Virtual Cloud Network (VCN) is indeed associated with a single route table. This route table determines how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed, providing a centralized control mechanism for routing within the VCN.

Q22. In the context of Oracle Cloud Infrastructure (OCI) Object Storage replication, what happens to objects that were uploaded to the source bucket before the replication policy was created?

Are automatically deleted from the source bucket

Are asynchronously replicated to the destination bucket upon policy creation

Are immediately replicated to the destination bucket upon policy creation

Are not replicated

Objects that were uploaded to the source bucket before the replication policy was created are not replicated to the destination bucket. The replication policy only applies to objects uploaded after the policy is set up and does not include pre-existing objects.

Q23. One of your customers is planning to consolidate many of their single-instance databases into a suitable database solution in OCI. Their goal is to optimize resource utilization and reduce maintenance and management overhead. What would you suggest as a migration architect?

Consolidate all databases into Exadata Database on Dedicated Infrastructure using Zero Downtime Migration

Group and migrate related databases into OCI Base Database service on multitenant architecture

Group related databases and use the cloud premigration advisor tool to get consolidation recommendation

Use Oracle Estate Explorer to identify databases that can be migrated to Autonomous Database and the recommended method for migration

Grouping and migrating related databases into OCI Base Database service on multitenant architecture allows for efficient resource utilization and reduced management overhead.

Q24. You plan to perform migrations between on-premises and OCI. What is the minimum bandwidth required with FastConnect as the dedicated network link between the environments?

10 Gbps

50 Gbps

100 Gbps

1 Gbps

The minimum bandwidth required for FastConnect is 1 Gbps to ensure fast and reliable data transfer between the environments.

Q25. Your company is looking to migrate its IT infrastructure into Oracle Cloud VMware Solution (OCVS). The source infrastructure includes a variety of workloads, such as a few business-critical VMs that require continuous availability, and a large set of non-critical dev-test VMs. As a migration cloud architect, you are exploring Hybrid Cloud Extension (HCX) migration methods to identify the best approaches for each type of workload. Which HCX migration method would be the most appropriate to use in order to migrate both business-critical VMs and dev-test VMs?

HCX Bulk Migration for migrating business-critical VMs and HCX vMotion for non-critical dev-test VMs

HCX vMotion for migrating business-critical VMs, and Cold Migrations for non-critical dev-test VMs

Cold Migration for migrating both business-critical and non-critical dev-test VMs

HCX Bulk Migration for migrating the business-critical VMs, and Cold Migrations for non-critical dev-test VMs

HCX vMotion is the most appropriate method for migrating business-critical VMs as it allows live migration without downtime, ensuring continuous availability. Cold Migrations can be used for non-critical dev-test VMs since downtime is acceptable for these workloads.

Q26. You have set up cross-region replication for a block volume in the US West (Phoenix) region, choosing US West (San Jose) as the destination. Now, you want to create a new volume from the volume replica in the US West (San Jose) region. What should you do?

Trigger the replica

No action required. By default, the replica is available as a block volume

Activate the replica

Initialize the replica

Activating the replica is the correct action to take in order to make the volume replica usable as a block volume in the US West (San Jose) region. This step ensures that the replica is ready for use and can be attached to instances for storage purposes.

Q27. Your company is planning to decommission their on-premises data center hosting a set of Virtual Machines (VMs) that heavily rely on VMware technologies. The goal is to migrate those VMs into OCI, make this transition as quick as possible, ensuring the environment is highly available and can be controlled by the company after the migration. What are the two advantages of using Oracle Cloud VMware Solution (OCVS)?

The company can bring their own product licenses (BYOL) for VMware products such as vSphere, vSAN, and NSX

The company can move those application VMs into OCVS “as-is”

The company can control root access to the OCVS environment

The company can free up their IT team as Oracle takes over the management, including updates and patching of the OCVS environment

The company could convert all of VMware-based applications into native OCI Compute instances

Two key advantages of using OCVS are the ability to bring your own licenses (BYOL) for VMware products, and the ability to move application VMs “as-is,” minimizing the need for modifications.

Q28. A company is assessing different strategies for migrating their applications from on-premises to Oracle Cloud Infrastructure. The applications are running on virtual machines, and a business requirement has been raised to containerize all applications within the OCI environment as part of the migration process. Which migration strategy fits well with this requirement?

Migrate VMs to a native OCI Compute instance

Migrate VMs to Oracle Cloud VMware Solution (OCVS)

Migrate VMs to a Software-as-a-Service solution in OCI

Migrate VMs to OCI Container Engine for Kubernetes (OKE)

Migrating VMs to OCI Container Engine for Kubernetes (OKE) is the most suitable strategy for containerizing applications within the OCI environment. OKE is a managed Kubernetes service that allows for the deployment, management, and scaling of containerized applications on OCI.

Q29. You are working as a migration cloud architect in an organization where you are responsible for cloud migrations from an on-premises data center. This environment consists of VMware and KVM infrastructures, both hosting a set of production application workloads. As part of a migration process, you are tasked with identifying appropriate methods for migrating workloads from both source environments into Oracle Cloud VMware Solution (OCVS). The application owners would like to validate the VMs after the migration and before switching over those workloads to production. Which two migration types can be used?

HCX Bulk Migration

Oracle Cloud Migrations service

HCX vMotion

Block Volume Replication

HCX OS Assisted Replication

HCX Bulk Migration and HCX vMotion are suitable methods for migrating workloads from VMware and KVM infrastructures to Oracle Cloud VMware Solution (OCVS). Bulk Migration allows for bulk migration of VMs, and vMotion allows live migration without downtime, both enabling VM validation before finalizing migration.

Q30. You have been tasked with provisioning an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which two statements are FALSE?

To access the cluster using kubectl, you have to set up a Kubernetes manifest file stored in the $HOME/.manifest directory

When a cluster’s Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file

The only available option when a cluster’s Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard

To access the cluster using kubectl, you have to set up a Kubernetes configuration file stored in the $HOME/.kube directory

Setting up a Kubernetes manifest file in the $HOME/.manifest directory is not a standard practice for accessing a Kubernetes cluster using kubectl. Manifest files are used to define and manage Kubernetes resources, such as pods, deployments, and services, but they are not used for configuring access to the cluster.
While controlling the cluster locally using kubectl and the Kubernetes Dashboard is one way to interact with a cluster, it is not the only available option when a cluster’s Kubernetes API endpoint has a public IP address. You can also access and manage the cluster remotely using kubectl from any environment that has network connectivity to the cluster.
