  "You can add secondary VNICs to an instance after it's launched. Each secondary VNIC can be in a subnet in the same VCN as the primary VNIC, or in a different subnet that is either in the same VCN or a different one. However, all the VNICs must be in the same availability domain as the instance." https://docs.cloud.oracle.com/en-us/iaas/Content/Network/Tasks/managingVNICs.htm

• Question 37:

  As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC) cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:

  The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.

  The cluster must be resilient to any potential infrastructure failures. To minimize latency, all nodes must be deployed within the same availability domain (AD). Adding or replacing nodes within the cluster should take no more than 30 minutes.

  Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)

  A. Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system.
  B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.
  C. Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time.
  D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.
  E. Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.
  B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.
  D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.

  A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains. To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain. Use fault domains to do the following things: Protect against unexpected hardware failures or power supply failures. Protect against planned outages because of Compute hardware maintenance.

• Question 38:

  Which two are true for achieving High Availability on Oracle Cloud Infrastructure? (Choose two.)

  A. Store your database across multiple regions so that half of the data resides in one region and the other half resides in another region.
  B. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highly available.
  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
  D. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
  E. Distribute your application servers across all Availability Domains within a region.
  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
  E. Distribute your application servers across all Availability Domains within a region.

• Question 39:

  You have hired a new employee to run reports from the Autonomous Data Warehouse (ADW) and are not confident in their SQL writing ability. Into which consumer group will you assign this individual to minimize the impact of their code?

  A. Lowest
  B. Medium
  C. Highest
  D. High
  E. Low
  E. Low

  ---

  in ADW, The tnsnames.ora file provided with the credentials zip file contains three database service names identifiable as high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Data Warehouse. high: The High database service provides the highest level of resources to each SQL statement resulting in the highest performance, but supports the fewest number of concurrent SQL statements. Any SQL statement in this service can use all the CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service is 3, this number is independent of the number of OCPUs in your database. medium: The Medium database service provides a lower level of resources to each SQL statement potentially resulting a lower level of performance, but supports more concurrent SQL statements. Any SQL statement in this service can use multiple CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service depends on the number of OCPUs in your database. low: The Low database service provides the least level of resources to each SQL statement, but supports the most number of concurrent SQL statements. Any SQL statement in this service can use a single CPU and multiple IO resources in your database. The number of concurrent SQL statements that can be run in this service can be up to 300 times the number of OCPUs. The predefined service names provide different levels of performance and concurrency for Autonomous DB Choose whichever database service offers the best balance of performance and concurrency. Use the low database service name. to minimize the impact of their SQLs to by low consumer group
