Question 2

Your company decided to move a few applications to Oracle Cloud Infrastructure (OCI) in the US West (us-phoenix-1)
region.
You need to design a cloud-based disaster recovery (DR) solution with a requirement to deploy the DR resources in the US
East (us-ashburn-1) region to minimize network latency.
What is the recommended deployment?

• A. Deploy production and DR applications in two separate virtual cloud networks (VCNs), each in different regions, and then use VCN local peering gateways for connectivity.
• B. Deploy production and DR applications in two separate VCNs, each in different regions. Connect them using a VCN remote peering connection.
• C. Deploy production and DR applications in the same VCN. Create production subnets in one AD, and DR subnets in another AD (assume a multi-AD region).
• D. Deploy production and DR applications in two separate VCNs in different availability domains (ADs) within the primary region, and then use a VCN remote peering connection for connectivity.

Answer:

D

Question 3

Your company uses the Oracle Cloud Infrastructure (OCI) Object Storage service to share large data sets with its data
science team. The data science team consists of 20 people who work from offices in Washington, D.C., and Tokyo. While
working in these offices, employees are assigned an IP address from the public IP range 129.146.31.0/27
Which two steps should you take to ensure that the Object Storage bucket used in this scenario was only accessible from
these office locations? (Choose two.)

• A. Write an IAM policy that includes the conditional statement where request.networkSource.name = CorpNet
• B. Set the bucket visibility to public and only share the URL with the data science team via email
• C. Create a pre-authenticated request for each data set and only share with the data science team via email
• D. Create a Network Source named CorpNetwork with a CIDR block of 129.146.31.0/27
• E. Create a Network Source named CorpNetwork with a CIDR block of 129.146.0.0/16
• F. Write an IAM policy that includes the conditional statement where request.region = 129.146.31.0/27

Answer:

C E

Question 4

You have compartments C and D under the root compartment in your Oracle Cloud Infrastructure (OCI) tenancy;
compartment C contains a sub-compartment also named
D. You are trying to move this sub-compartment D to the parent compartment D like shown in the picture, but the move fails.

What is the reason for this error?

• A. You need to move all the compartments in the hierarchy to the new parent compartment.
• B. You cannot move a subcompartment to another parent compartment.
• C. Both parent and child compartments cannot have the same name.
• D. You are trying to move this sub-compartment D to the parent compartment D like shown in the picture, but the move fails. What is the reason for this error? Sub-compartment D needs to be empty before it can be moved.

C

moving compartments)

Question 5

You deployed a database on a Standard Compute instance in Oracle Cloud Infrastructure (OCI) due to cost concerns. The
database requires additional storage with high I/O and you decided to use OCI Block Volume service for it.
With this requirement in mind, which elastic performance option should you choose for the Block Volume?

• A. Balanced Performance
• B. Higher performance
• C. Extreme performance
• D. Lower cost

Answer:

B

Question 6

Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept
(POC) to deploy Oracle PeopleSoft.
If your existing resources are being maintained in the root compartment, what is the recommended approach for defining
security for the upcoming POC?

• A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.
• B. Create a new tenancy for the POC and provision all new resources into the root compartment. Grant appropriate permissions to create and manage resources within the root compartment.
• C. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications.
• D. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC.

Answer:

A

Question 7

You deployed an Oracle Cloud Infrastructure (OCI) compute instance (VM.Standard2.16) to run a SQL database. After a few
weeks, you need to increase disk performance by using NVMe disks but keeping the same number of CPUs. As a first step,
you terminate the instance and preserve the boot volume.
What is the next step?

• A. Create a new instance using a VM.Standard1.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
• B. Create a new instance using a VM.DenseIO2.8 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
• C. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to block volume.
• D. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.

Answer:

D

Question 8

You are running an online gaming application hosted on a VM.Standard2.1 instance shape in Oracle Cloud Infrastructure. As
the game becomes popular, you identify network throughput as a bottleneck on your instance when uploading user data.
Though you want to resolve the issue, you want to observe the demand for a week before adding new application instances.
Which action is the most efficient way to resolve this issue?

• A. Add a secondary virtual network interface card (VNIC).
• B. Change shape of the instance to a higher network bandwidth instance.
• C. Delete the instance while preserving boot volume and spin up a new higher network bandwidth instance with this boot volume.
• D. Change the performance tier of attached block volume to High Performance.

Answer:

B

Question 9

You are managing a tier-1 OLTP application on an Oracle Autonomous Transaction Processing (ATP) database. Your
business needs to run hourly batch processes on this ATP database that may consume more CPUs than what is available
on the server.
How can you limit these batch processes to not interfere with the OLTP transactions?

• A. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.
• B. Copy OLTP data into new tables in a new table space and run batch processes against these new tables.
• C. Disable automated backup during the batch process operations.
• D. ATP is designed for OLTP workload only, you cannot run batch processes on ATP.

Answer:

A

Question 10

A customer launched a compute instance in the Virtual Cloud Network (VCN), which has an internet gateway, a service
gateway, a default security lists and a default route table. The customer opened up Port 22 in the security lists attached to
the compute instance subnet, however is still unable to connect to compute instances using SSH.
Which action can resolve this issue?

• A. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic in addition to the port 22.
• B. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table: Destination CIDR: 0.0.0.0/0 Target: Service Gateway (SGW)
• C. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table: Destination CIDR: 0.0.0.0/0 Target: Dynamic Routing Gateway (DRG)
• D. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table: Destination CIDR: 0.0.0.0/0 Target: Internet Gateway (IGW)
