QUESTION 1

You have been tasked with creating one virtual cloud network (VCN) each for two lines of business (LOB) applications.
LOB A and LOB B will need to communicate with each other. To ensure that you can utilize VCN peering, which network CIDR ranges should be used?

A. VCN A (10.0.0.0/16) and VCN B (10.1.0.0/16)
B. VCN A (10.0.2.0/16) and VCN B (10.0.2.0/25)
C. VCN A (10.0.0.0/16) and VCN B (10.0.16.0/24)
D. VCN A (172.16.0.0/24) and VCN B (172.16.0.0/28)

Correct Answer: A

VCN A (10.0.0.0/16) will use a range of IPS from 10.0.0.0 to 10.0.255.255 and VCN B (10.1.0.0/16) will use a range of IPS from 10.1.0.0 to 10.1.255.255 so will not be any Overlap between the 2 VCNs

QUESTION 2

You have an AI/ML application running on Oracle Cloud Infrastructure. You identified that the application needs GPU and at least 20Gbps Network throughput. The application is currently using a VM.Standard2.1 computes without any block storage attached to it.
Which two options allow you to get your required performance for your application? (Choose two.)

A. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.

B. Terminate the compute instance preserving the boot volume. Create a new compute instance using the
VM.Standard2.2 shape using the boot volume preserved, but no block volume attached.

C. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.GPU3.4 shape using the boot volume preserved and use the NVMe devices to host your application.

D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.HPC2.36 shape using the boot volume preserved and use the NVMe devices to host your application.

E. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved and attach a new block volume to host your application.

Correct Answer: DE

QUESTION 3

Which two actions will occur when a back-end server that is registered with a backend set is marked to drain connections? (Choose two.)

A. It disallows new connections to that backend server.
B. It keeps the connections to that instance open and attempts to complete any in-flight requests.
C. It redirects the requests to a user-defined error page.
D. It immediately closes all existing connections to that instance.
E. It forcibly closes all connections to that instance after a timeout period.

Correct Answer: AB

References:
https://docs.cloud.oracle.com/iaas/Content/Balance/Reference/sessionpersistence.htm The Load Balancing service considers a server-marked drain available for existing persisted sessions. New requests that are not part of an existing persisted session are not sent to that server.

Which two resources are available by default when your Oracle Cloud Infrastructure tenancy is provisioned?

A. an NVMe SSD boot disk for each instance, whose size is determined by the image and shape of the instance

B. a range of public IP addresses that are reserved for your tenancy

C. a set of images, where each image is a template of a virtual hard drive that consists of the OS and installed software and applications

D. a variety of shapes, where each shape determines the number of CPUs and memory allocated to an instance.

Correct Answer: CD

QUESTION 6

You are working for a financial institution that is currently running two web applications in Oracle Cloud
Infrastructure (OCI). All resources were created in the root compartment. Your manager asked you to deploy new resources to support a proof-of-concept (POC) for Oracle FlexCube.
You must ensure that the FlexCube resources are secured and cannot be affected by the team that manages the two web applications.
Which two tasks should you complete to ensure the required security of your resources? (Choose two.)

A. Create a new compartment for the two web applications and move the existing resources into the compartment. Deploy the FlexCube application into the root compartment. Create a new policy in the root compartment that gives the FlexCube project team the ability to manage all resources in the tenancy.

B. Create a new policy in the root compartment for the FlexCube project team. Assign a policy statement that grants the FlexCube project team the ability to manage all resources in the tenancy, where a specific tag key and tag value are present.

C. Create a Tag Default within the root compartment with a default value of ${iam.principle.name} so that each new resource created is tagged with the name of the person who created it. Create a new IAM policy that allows users to only modify the resources they created.

D. Create a new compartment for the two web applications and move the existing resources into this compartment.
Modify the existing policy for the team that manages these applications so that the scope of access is defined as this new compartment.

E. Create a new compartment for the FlexCube application deployment. Create a policy in this compartment for the project team that gives them the ability to manage all resources within the scope of this compartment.

Correct Answer: CD

QUESTION 7

Your on-premises hosted application uses an Oracle database server. Your database administrator must have access to the database server for managing the application. Your database server is sized for seasonal peak workloads, which results in high licensing costs. You want to move your application to Oracle Cloud Infrastructure (OCI) to take advantage of CPU scaling options.
Which database offering on OCI would you select?

A. bare metal DB systems
B. VM DB systems
C. Autonomous Transactions Processing (ATP)
D. Autonomous Data Warehouse (ADW)

Correct Answer: A

-In, Oracle Autonomous Database, Customers are not given OS logons or SYSDBA privileges to prevent phishing attacking.

If a bare metal DB system requires more compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system.
You cannot change the number of CPU cores for a virtual machine DB system in the same way as a metal DB system.

Instead, you must change the shape to one with a different number of OCPUs Changing the shape does not impact the amount of storage available to the DB system. However, the new shape can have different memory and network bandwidth characteristics, and you might need to reapply any customizations to these aspects after the change.

QUESTION 8

You are an administrator with an application running on OCI. The company has a fleet of OCI compute virtual instances behind an OCI Load Balancer. The OCI Load Balancer Backend Set health check API is providing a Critical\\' level warning. You have confirmed that your application is running healthy on the backend servers. What is the possible reason for thisCritical\’ warning?

A. A user does not have correct IAM credentials on the Backend Servers.
B. The Backend Server VCN\’s Route Table does not include the route for OCI LB.
C. OCI Load Balancer Listener is not configured correctly.
D. The Backend Server VCN\’s Security List does not include the IP range for the source of the health check requests.

Correct Answer: D

References: “In this case, your security rules might not include the IP range for the source of the health check requests.
You can find the health check source IP on the Details page for each backend server. You can also use the API to find the IP in the source IP address field of the HealthCheckResult object.”
https://docs.cloud.oracle.com/iaas/Content/Balance/Tasks/editinghealthcheck.htm#health-status

QUESTION 9

You are planning to deploy a multi-region web application in Oracle Cloud Infrastructure (OCI). You have customers in North America, Asia, and Europe who will access the application. What service is available in OCI to help you choose the regions with the lowest latency to these markets?

A. Internet Intelligence
B. FastConnect
C. IPsec VPN
D. DNS Zone Management

Correct Answer: A

QUESTION 10

Which two statements are true about restoring a volume from a block volume backup in Oracle Cloud Infrastructure Block Volume service?

B. You can only restore a volume to the same availability domain in which the original block volume resides.
C. You can restore a block volume backup to a larger volume size.
D. You can restore a volume to any availability domain within the same region where the backup is stored.
E. You can restore only one volume from a manual block volume backup.

Correct Answer: CD

Reference https://docs.cloud.oracle.com/enus/iaas/Content/Block/Tasks/restoringavolumefromabackup.htm

QUESTION 11

Which two statements are true about an Oracle Cloud Infrastructure Virtual Cloud Network (VCN)? (Choose two.)

A. A VCN can reside in multiple Oracle Cloud Infrastructure regions and Availability Domains.
B. A VCN covers a single contiguous IPv4 CIDR block of your choice.
C. An allowable VCN size range is/16 to /30.
D. A VCN creates the dynamic routing gateway by default.

Correct Answer: BC

VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. The allowable VCN size range is /16 to /30

QUESTION 12

How can you provide users access to an existing compartment?

A. by granting users access to a compartment when the compartment is created
B. by adding users to a group and defining a policy to provide the group access to the compartment
C. by adding users to a compartment. All users in the compartment will have access to the objects in the compartment.
D. by granting access directly to the user when the user is created

Correct Answer: B

A policy is a document that specifies who can access which Oracle Cloud Infrastructure resources that your company has, and how. A policy simply allows a group to work in certain ways with specific types of resources in a particular compartment
In general, here\’s the process an IAM administrator in your organization needs to follow:
Define users, groups, and one or more compartments to hold the cloud resources for your organization.

Create one or more policies, each written in the policy language. Place users into the appropriate groups depending on the compartments and resources they need to work with.
Provide the users with the one-time passwords that they need in order to access the Console and work with the compartments. For more information,

QUESTION 13

What happens when you run terraform plan?

A. It configures, reconfigures, and instantiates resources and their dependencies.
B. It shows the operator the course of action that would be taken if a change is applied.
C. It deletes all existing resources and re-creates them.
D. It shows a dependency graph.

Correct Answer: B

References:
The terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.
This command is a convenient way to check whether the execution plan for a set of changes matches your expectations without making any changes to real resources or to the state. For example, terraform plan might be run before committing a change to version control, to create confidence that it will behave as expected.
