NEW QUESTION 50

You are working as a solution architect for an online retail store to create a portal to allow the users to pay for their groceries using credit cards. Since the application is not fully compliant with the Payment Card Industry Data Security Standard (PCI DSS), your company is looking to use a third party payment service to process credit card payments.

The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a time However, your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up to create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment service over the Interne! to complete the transaction What solution can you implement to make sure that all compute Instances can connect to the third party system to process the payments aw peak traffic demand?

  • A. Create an OCI Command Line Interface (CLI) script to automatically reserve public IP address for the compute instances. On the third-party services, whitelist the Reserved public IP.
  • B. Route credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitelist the public IP associated with the NAT Gateway.
  • C. Route payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service.
  • D. Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the Internet Gateway.

NEW QUESTION 51

By copying block volume backups to another region at regular intervals, it makes it easier for you to rebuild applications and data in the destination region if a region-wide disaster occurs in the source region.

Which IAM Policy statement allows the VolumeAdmins group to copy volume backups between regions '

  • A. Allow group VolumeAdmins to copy volume' backups in tenancy
  • B. Allow group VolumeAdmins to use volumes in tenancy
  • C. Allow group VolumeAdmins to inspect volumes in tenancy
  • D. Allow group VolumeAdmins to manage volume-family In tenancy

Answer: D

Explanation:

The backups feature of the Oracle Cloud Infrastructure Block Volume service lets you make a point-intime snapshot of the data on a block volume.These backups can then be restored to new volumes either immediately after a backup or at a later time that you choose.

You can copy block volume backups between regions using the Console, command line interface (CLI), SDKs, or REST APIs.

To copy volume backups between regions, you must have permission to read and copy volume backups in the source region, and permission to create volume backups in the destination region.

to do all things with block storage volumes, volume backups, and volume groups in all compartments with the exception of copying volume backups across regions.

Allow group VolumeAdmins to manage volume-family in tenancy

The aggregate resource type volume-family does not include the VOLUME_BACKUP_COPY permission, so to enable copying volume backups across regions you need to ensure that you include the third statement in that policy, which is:

Allow group VolumeAdmins to use volume-backups in tenancy where request.permission='VOLUME _BACKUP_COPY'

NEW QUESTION 52

Your team is conducting a root analysis (RCA) following a recent, unplanned outage. One of the block volumes attached to your production WebLogic server was deleted and you have tasked with identifying the source of the action. You search the Audit logs and find several Delete actions that occurred in the previous 24 hours. Given the sample of this event.



Which item from the event log helps you identify the individual or service that initiated the DeleteVolume API call?

  • A. requestAgent
  • B. eventource
  • C. requestOrigin
  • D. eventId
  • E. principalld

Answer: E

Explanation:

The Oracle Cloud Infrastructure Audit service automatically records calls to all supported Oracle Cloud Infrastructure public application programming interface (API) endpoints as log events. Currently, all services support logging by Audit.

Every audit log event includes two main parts:

Envelopes that act as a container for all event messages

Payloads that contain data from the resource emitting the event message The identity object contains the following attributes.

data.identity.authType The type of authentication used.

data.identity.principalId The OCID of the principal.

data.identity.principalName The name of the user or service. This value is the friendly name associated with principalId .

NEW QUESTION 53

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

Answer: A,B

Explanation:

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 allocate resources with a high level of flexibility.
