  D. No Pod gets created.
  C. A single Pod with two containers is created.

• Question 62:

  You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

  A. Terminate the VM.Standard2.24 instance and do not preserve the boot volume
  B. Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks
  C. Terminate the VM.Standard2.24 instance and preserve the boot volume
  D. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes
  A. Terminate the VM.Standard2.24 instance and do not preserve the boot volume
  D. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes

  You can permanently terminate (delete) instances that you no longer need. Any attached VNICs and volumes are automatically detached when the instance terminates. Eventually, the instance's public and private IP addresses are released and become available for other instances. By default, the instance's boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that you can attach it to a different instance as a data volume, or use it to launch a new instance. Dense I/O Shapes Designed for large databases, big data workloads, and applications that require high-performance local storage. DenseIO shapes include locally-attached NVMe-based SSDs. so once you create the VM.DenseIO you need to moce the Database to locally-attached NVMe-based SSDs

• Question 63:

  Your organization has deployed a large, complex application across multiple compute instances in Oracle Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them. You want to create a time

  consistent backup of these block volume storage.

  Which implementation strategy should be used?

  A. Create a manual backup of each volume
  B. Use scripts available in OCI to backup block volume storage
  C. Group volumes in a volume group first and then use available scripts in OCI
  D. Group volumes in a volume group and create a manual backup of the volume group
  D. Group volumes in a volume group and create a manual backup of the volume group

  ---

  The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for

  your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point- in-time and crash-consistent.

  This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup.

  To create a backup of the volume group

  Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Volumes Groups. In the Volume Groups list, click Create Volume Group Backup in the Actions menu for the volume group you want to create a backup for.

• Question 64:

  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.
  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.

  Remote VCN peering is the process of connecting two VCNs in different regions The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.

• Question 65:

  You have been asked to create an Identity and Access Management (IAM) user that will authenticate to Oracle Cloud Infrastructure (OCI) API endpoints. This user must not be given credentials that would allow them to log into the OCI

  console.

  Which two authentication options can you use? (Choose two.)

  A. SSL certificate
  B. API signing key
  C. SSH key pair
  D. PEM Certificate file
  E. Auth token
  B. API signing key
  E. Auth token

• Question 66:

  You have launched a compute instance running Oracle database in a private subnet in the Oracle Cloud Infrastructure US East region. You have also created a Service Gateway to back up the data files to OCI Object Storage in the same region. You have modified the security list associated with the private subnet to allow traffic to the Service Gateway, but your instance still cannot access OCI Object Storage. How can you resolve this issue?

  A. Add a stateful rule that enables ingress HTTPS (TOP port 443) traffic to 001 Object Storage in the security list associated with the private subnet
  B. Add a stateful rule that enables egress HTTPS (TCP port 443) traffic to OCI Object Storage in the security list associated with the private subnet
  C. Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'
  D. Use the default Security List, which has ports open for OCI Object Storage
  C. Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'

  ---

  A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT is required to reach those specific services. The resources in the

  VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.

  The service gateway is regional and enables access only to supported Oracle services in the same region as the VCN.

  For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target. For the destination, you must use the service CIDR label

  that is enabled for the service gateway. This means that you don't have to know the specific public CIDRs, which could change over time.

• Question 67:

  Which two statements are true when Oracle Data Guard is configured (using the Console) between two Virtual Machine DB Systems deployed in Oracle Cloud Infrastructure? (Choose two.)

  A. Primary is a 1-node RAC DB system and Standby is a 2-node RAC DB system.
  B. Primary is a 2-node RAC DB system and Standby is a 2-node RAC DB system.
  C. Primary is a 1-node RAC DB system and Standby is a 1-node RAC DB system.
  D. Primary is a 2-node RAC DB system and Standby is a 1-node RAC DB system.
  E. Primary is a Bare Metal DB system and Standby is a 1-node RAC DB system.
  A. Primary is a 1-node RAC DB system and Standby is a 2-node RAC DB system.
  C. Primary is a 1-node RAC DB system and Standby is a 1-node RAC DB system.

• Question 68:

  Your on-premises hosted application uses 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)
  A. bare metal DB systems

  ---

  -

  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 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 69:

  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 the lowest latency to these markets?

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

• Question 70:

  You are designing a lab exercise for your team that has a large number of graphics with large file sizes. The application becomes unresponsive if the graphics are embedded in the application. You have uploaded the graphics to Oracle Cloud

  Infrastructure and only added the URL in the application. You need to ensure these graphics are accessible without requiring any authentication for an extended period of time.

  How can you achieve these requirements?

  A. Create pre-authenticated requests (PAR) and specify 00:00:0000 as the expiration time.
  B. Make the object storage bucket private and all objects public and use the URL found in the Object "Details".
  C. Make the object storage bucket public and use the URL found in the Object "Details".
  D. Create PARs and do not specify an expiration date.
  C. Make the object storage bucket public and use the URL found in the Object "Details".

  ---

  Pre-authenticated requests provide a way to let you access a bucket or an object without having your own credentials. For example, you can create a request that lets you upload backups to a bucket without owning API keys.

  When you create a bucket, the bucket is considered a private bucket and the access to the bucket and bucket contents requires authentication and authorization. However, Object Storage supports anonymous, unauthenticated access to a

  bucket. You make a bucket public by enabling read access to the bucket.

  pre-authenticated requests have to select expiration date
