  VM.DeselO2.24 compute instance include locally attached NVMe devices. These devices provide extremely low latency, high performance block storage that is ideal for big data, OLTP, and any other workload that can benefit from high-performance block storage. A protected RAID array is the most recommended way to protect against an NVMe device failure. There are three RAID levels that can be used for the majority of workloads: RAID 1: An exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair

• Question 72:

  A digital marketing company is planning to host a website on Oracle Cloud Infrastructure (OCI) and leverage OCI Container Engine for Kubernetes (OKE). The web server will make API calls to access OCI Object Storage to store all images uploaded by users. For security purposes, your manager instructed you to ensure that the credentials used by the web server to allow access not stored locally on the compute instance. What solution results in an Implementation with the least effort for this scenario?

  A. Configure the credentials using Instance Principal to allow the web server to make API calls to OCl Object Storage
  B. Configure the credentials using OCI Registry (OC1R) which will automatically connect with OKE allowing the web server to make API calls to OCI Object Storage.
  C. Configure the credentials to use Transparent Data Encryption (TDE) which will automatically allow the web server to make API calls to OCl Object Storage.
  D. Configure the credentials using OCI Key Management to allow an instance to make API calls and grant access to OCl Object Storage.
  C. Configure the credentials to use Transparent Data Encryption (TDE) which will automatically allow the web server to make API calls to OCl Object Storage.

  INSTANCE PRINCIPALS The IAM service feature that enables instances to be authorized actors (or principals) to perform actions on service resources. Each compute instance has its own identity, and it authenticates using the certificates that are added to it. These certificates are automatically created, assigned to instances and rotated, preventing the need for you to distribute credentials to your hosts and rotate them. Dynamic groups A special type of group that contains resources (such as compute instances) that match rules that you define (thus the membership can change dynamically as matching resources are created or deleted). These instances act as "principal" actors and can make API calls to services according to policies that you write for the dynamic group. The following steps summarize the process flow for setting up and using instances as principals. The subsequent sections provide more details. 1 Create a dynamic group. In the dynamic group definition, you provide the matching rules to specify which instances you want to allow to make API calls against services. 2 Create a policy granting permissions to the dynamic group to access services in your tenancy (or compartment). 3 A developer in your organization configures the application built using the Oracle Cloud Infrastructure SDK to authenticate using the instance principals provider. The developer deploys the application and the SDK to all the instances that belong to the dynamic group. 4 The deployed SDK makes calls to Oracle Cloud Infrastructure APIs as allowed by the policy (without needing to configure API credentials). 5 For each API call made by an instance, the Audit service logs the event, recording the OCID of the instance as the value of principalId in the event log.

• Question 76:

  You work for a German company as the Lead Oracle Cloud Infrastructure architect. You have designed a highly scalable architecture for your company's business critical application which uses the Load Balancer service auto which uses the

  Load Balancer service, autoscaling configuration for the application servers and a 2 Node VM Oracle RAC database. During the peak utilization period of the- application yon notice that the application is running slow and customers are

  complaining. This is resulting in support tickets being created for API timeouts and negative sentiment from the customer base.

  What are two possible reasons for this application slowness?

  A. Autoscaling configuration for the application servers didn't happen due to 1AM policy that's blocking access to the application server compartment
  B. The Load Balancer configuration is not sending traffic to the listener of the application servers.
  C. Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
  D. Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers
  E. The Load Balancer doesn't have a Network Security Group to allow traffic to the application servers.
  C. Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
  D. Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers

  Autoscaling Autoscaling enables you to automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand. Prerequisites

  -

  You have an instance pool. Optionally, you can attach a load balancer to the instance pool. For steps to create an instance pool and attach a load balancer, see Creating an Instance Pool.

  -

  Monitoring is enabled on the instances in the instance pool. For steps to enable monitoring, see Enabling Monitoring for Compute Instances.

  -

  The instance pool supports the maximum number of instances that you want to scale to. This limit is determined by your tenancy's service limits. About Service Limits and Usage When you sign up for Oracle Cloud Infrastructure, a set of service limits are configured for your tenancy. The service limit is the quota or allowance set on a resource. For example, your tenancy is allowed a maximum number of compute instances per availability domain. These limits are generally established with your Oracle sales representative when you purchase Oracle Cloud Infrastructure. Compartment Quotas Compartment quotas are similar to service limits; the biggest difference is that service limits are set by Oracle, and compartment quotas are set by administrators, using policies that allow them to
