You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want to have all your compute instances resistant to hardware failure.
Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure? (Choose two.)

  • A. Create a custom image of your system drive each time you change the image.
  • B. Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
  • C. Design your system with redundant compute modes in different Availability Domains to support the failover capability.
  • D. Create backups of your block volumes that are associated with compute instances in different regions.

For what business need should you use Database Cloud Service (DBCS) instead of Oracle database on a compute instance?

  • A. to bring your own license on a compute service
  • B. to lower license and infrastructure cost
  • C. to implement Oracle RAC for high availability
  • D. to build an Oracle database on a compute service


Answer : D

You need to create a high performance shared file system service, and have been advised to use OCI File Storage Service. You have logged into the OCI
Console, created a File System in an availability domain, and followed the steps to mount the shared file system on your Oracle Linux virtual Instance. However, you are still unable to access the shared file system from your Linux instance.
What is the likely reason for this?

  • A. There are no security list rules for mount target traffic
  • B. There is no internet gateway set up for mount target traffic
  • C. There is no Identity and Access Management (IAM) policy set up to allow you to access the mount target
  • D. There is no route in your VCN"™s route table for mount target traffic


Answer : C

Which two statements define the types of DNS resolvers that exist? (Choose two.)

  • A. A custom resolver allows instances to use the host names of the hosts in your on-prem network that are connected to your VCN by an IPSec VPN connection.
  • B. A VCN resolver allows instances to use the host names of the hosts in your on-prem network that are connected to your VCN by an IPSec VPN connection.
  • C. A VCN resolver allows instances to use host names to communicate with instances on other VCNs in your tenancy.
  • D. An Internet resolver allows instances to use the host names that are published on the Internet.


Answer : AD

What is a "transfer package" when transferring data to OCI via the OCI Data Transfer Service?

  • A. A transfer package is the logical representation of the physical shipment containing the HDD transfer devices that you ship to Oracle to upload to OCI.
  • B. A transfer package is the software Oracle provides for you to prepare transfer devices for shipment to Oracle
  • C. A transfer package contains the physical devices.
  • D. A transfer package is the archive file that the Data Transfer Service Utility (dts) writes to the transfer device.

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


Answer : B

You are the Solutions Architect of a large company and are tasked with migrating all your services to Oracle Cloud Infrastructure. As part of this, you first design a
Virtual Cloud Network (VCN) with a public subnet and a private subnet. Then in order to provide Internet connectivity to the instances in your private subnet, you create an Oracle Linux instance in your public subnet and configure NAT on it. However, even after adding all related security list rules and routes in the Route
Table, your private subnet instances still cannot connect to the Internet.
Which action should you perform to enable Internet connectivity?

  • A. Disable "Source and Destination Check" on the VNIC of your Linux instance.
  • B. There is no way that a private subnet can connect to the Internet.
  • C. Create a Dynamic Routing Gateway (DRG) and route your private IP traffic to the DRG.
  • D. Restart the NAT instance.


Answer : A

When terminating a compute instance, which statement is true?

  • A. The instance needs to be stopped first, and then terminated.
  • B. The boot volume is always deleted.
  • C. All block volumes attached to the instance are terminated.
  • D. Users can preserve the boot volume associated with the instance.


Answer : D

There are multiple options of migrating Oracle Databases from on-premises to Oracle Cloud Infrastructure. Which two characteristics do you need to consider when choosing a migration method? (Choose two.)

  • A. On-premises database character set and application version
  • B. On-premises database version and quantity of data, including indexes
  • C. On-premises host operating system platform and network bandwidth
  • D. On-premises connectivity using remote and local VCN peering

Within your tenancy you have a compute instance with a boot volume and a block volume attached. The boot volume contains the OS and the attached block volume contains the instance"™s important data. Logs on the boot volume have filled the boot volume and are causing issues with the OS.
What should you do to resolve this situation?

  • A. Stop the instance that is full. Create a manual backup of the block storage before making changes. Detach the block volume, create a new instance of the same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.
  • B. Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.
  • C. Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.
  • D. Create a manual backup of the block storage instance. Create a custom image of the full instance. Once that completes deploy the custom image to a new instance.


Answer : B

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

  • 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.


Answer : AB

Your company is moving an Internet-facing, 2-tier web application into Oracle Cloud Infrastructure. The application must have a highly available architecture.
Which two design options would you consider? (Choose two.)

  • A. Configure a Dynamic Route Gateway in your VCN and make it highly available.
  • B. Configure a NAT instance in your Virtual Cloud Network (VCN). Create a route rule by using the private IP of the NAT instance as a route target for all the private subnets in your VCN.
  • C. Create an Internet Gateway and attach it to your VCN. Deploy public load balancer nodes into two Available Domains.
  • D. Place all web servers behind a public load balancer.


Answer : BC

You are an administrator with an application running in Oracle Cloud Infrastructure (OCI). The company has a fleet of OCI compute virtual instances behind a load balancer. The 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 this "˜Critical"™ warning?

  • A. The load balancer listener is not configured correctly.
  • B. A user does not have correct Identity and Access Management (IAM) credentials on the backend servers.
  • C. The security list associated with the subnet in which the backend server is provisioned does not include the IP range for the source of the health check requests.
  • D. The route table associated with the subnet in which the backend server is provisioned does not include the route for OCI load balancer.


Answer : C
