• Question 145:

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

  ---

  to Increase disk performance by using NVMe disks you can use Dense IO Shape also as the number of CPUs will not change so we should VM.DenseIO2.16

• Question 146:

  You have five different company locations spread across the US. For a proof-of-concept (POC) you need to setup secure and encrypted connectivity to your workloads running in a single virtual cloud network (VCN) in the Oracle Cloud

  Infrastructure Ashburn region from all company locations.

  What would meet this requirement?

  A. Create five internet gateways in your VCN and have separate route table for each internet gateway.
  B. Create five virtual circuits using FastConnect for each company location and terminate those connections on a single dynamic routing gateway (DRG). Attach that DRG to your VCN.
  C. Create five IPsec connections with each company location and terminate those connections on a single DRG. Attach that DRG to your VCN.
  D. Create five IPsec VPN connections with each company location and terminate those connections on five separate DRGs. Attach those DRGs to your VCN.
  C. Create five IPsec connections with each company location and terminate those connections on a single DRG. Attach that DRG to your VCN.

  ---

  Access to Your On-Premises Network

  There are two ways to connect your on-premises network to Oracle Cloud Infrastructure:

  VPN Connect: Offers multiple IPSec tunnels between your existing network's edge and your VCN, by way of a DRG that you create and attach to your VCN.

  Oracle Cloud Infrastructure FastConnect: Offers a private connection between your existing network's edge and Oracle Cloud Infrastructure. Traffic does not traverse the internet. Both private peering and public peering are supported. That

  means your on-premises hosts can access private IPv4 addresses in your VCN as well as regional public IPv4 addresses in Oracle Cloud Infrastructure (for example, Object Storage or public load balancers in your VCN).

  You can use one or both types of the preceding connections. If you use both, you can use them simultaneously, or in a redundant configuration. These connections come to your VCN by way of a single DRG that you create and attach to your

  VCN. Without that DRG attachment and a route rule for the DRG, traffic does not flow between your VCN and on-premises network. At any time, you can detach the DRG from your VCN but maintain all the remaining components that form

  the rest of the connection. You could then reattach the DRG again, or attach it to another VCN.

• Question 147:

  Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept (POC) to deploy 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. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC.
  C. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications.
  D. Create a new tenancy for the POC. Provision all new resources into the root compartment. Grant appropriate permissions to create and manage resources within the root compartment.
  A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.

  ---

  If your organization is small, or if you are still in the proof-of-concept stage of evaluating Oracle Cloud Infrastructure, consider placing all of your resources in the root compartment (tenancy). This approach makes it easy for you to quickly view and manage all your resources. You can still write policies and create groups to restrict permissions on specific resources to only the users who need access. If you plan to maintain all your resources in the root compartment, we recommend setting up a separate sandbox compartment to give users a dedicated space to try out features. In the sandbox compartment, you can grant users permissions to create and manage resources, while maintaining stricter permissions on the resources in your tenancy (root) compartment. https://www.oracle.com/a/ocom/docs/best-practices-for-iam-on-oci.pdf

• Question 148:

  Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems Data Guard service?

  A. Both DB systems must use the same VCN, and port 1521 must be open
  B. Data guard configuration on the OCI is limited to a virtual machine only
  C. Data guard implementation for Bare Metal shapes requires two DB Systems, one containing the primary database and one containing the standby database.
  D. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.
  A. Both DB systems must use the same VCN, and port 1521 must be open
  C. Data guard implementation for Bare Metal shapes requires two DB Systems, one containing the primary database and one containing the standby database.

  ---

  An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB

  system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data

  Guard.

  Requirement details are as follows:

  -Both DB systems must be in the same compartment.

  -

  The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).

  -

  If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database.

  -

  Configure the security list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).

• Question 149:

  Which statement is NOT true about the Oracle Cloud Infrastructure Object Storage service?

  A. Object storage resources can be shared across tenancies.
  B. Immutable option for data stored in the Object Storage can be set via retention rules.
  C. Object versioning is enabled at namespace level.
  D. Object lifecycle rules can be used to either archive or delete objects.
  B. Immutable option for data stored in the Object Storage can be set via retention rules.

• Question 150:

  You currently manage an e-commerce application that utilizes 25 identical compute resources to handle customer traffic. The stakeholders have asked you to create another 25 identical compute resources in order to deploy and test a new version of the software? What is the most efficient process to create 25 additional compute resources that are identical to the first 25?

  A. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers
  B. Create a manual backup of each boot volume belonging to the 25 servers. Restore each backup to create 25 new boot volumes, from which you will provision 25 more servers
  C. Provision a new server and configure it to be identical to the first 25. Create a custom image from the new server, then use the custom image to provision 24 more servers
  D. Clone the boot volume of 1 of the 25 servers. Use the boot volume clone to provision 25 more servers
  A. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers
