NEW QUESTION 15
You are the Solution Architect that designed this Oracle Cloud Infrastructure (OCI) compartment layout for your organization:

The development team has deployed quite a few instances under ‘Compute’ Compartment and the operations team needs to list the Instances under the same compartment for their testing. Both teams, development and operations are part of a group called ‘Eng-group’ You have been looking for an option to allow the operations team to list the instances without access any confidential information or metadata of resources.
Which IAM policy should you write based on these requirements?

Allow group Eng-group to inspect instance-family in compartment Dev-Team:Compute and attach the policy to ‘Engineering’ Compartment

Allow group Eng-group to inspect instance-family in compartment Dev-Team: Compute and attach the policy to ‘SysTest Team’ Compartment

Allow group Eng-group to read instance-family in compartment Compute and attach the policy to ‘Engineering’ Compartment.

Allow group Eng-group to read instance-family in compartment Dev-Team-.Compute and attach the policy to’Dev-Team’

Policy Attachment
When you create a policy you must attach it to a compartment (or the tenancy, which is the root compartment). Where you attach it controls who can then modify it or delete it. If you attach it to the tenancy (in other words, if the policy is in the root compartment), then anyone with access to manage policies in the tenancy can then change or delete it. Typically that’s the Administrators group or any similar group you create and give broad access to. Anyone with access only to a child compartment cannot modify or delete that policy.
When you attach a policy to a compartment, you must be in that compartment and you must indicate directly in the statement which compartment it applies to. If you are not in the compartment, you’ll get an error if you try to attach the policy to a different compartment. Notice that attachment occurs during policy creation, which means a policy can be attached to only one compartment.
Policies and Compartment Hierarchies
a policy statement must specify the compartment for which access is being granted (or the tenancy).
Where you create the policy determines who can update the policy. If you attach the policy to the compartment or its parent, you can simply specify the compartment name. If you attach the policy further up the hierarchy, you must specify the path. The format of the path is each compartment name (or OCID) in the path, separated by a colon:
<compartment_level_1>:<compartment_level_2>: . . . <compartment_level_n> to allow action to compartment Compute so you need to set the compartment PATH as per where you attach the policy as below examples if you attach it to Root compartment you need to specify the PATH as following Engineering:Dev-Team:Compute if you attach it to Engineering compartment you need to specify the PATH as following Dev-Team:Compute if you attach it to Dev-Team or Compute compartment you need to specify the PATH as following Compute Note : in the Policy inspect verb that give the Ability to list resources, without access to any confidential information or user-specified metadata that may be part of that resource.

NEW QUESTION 16
Your customer has gone through a recent reorganization. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company’s new organizational structure. (Refer to the exhibit)

They have made the following change:
Compartment A is moved, and its new parent compartment is compartment Dev.
Policy defined in compartment A: Allow group G1 to manage instance-family in compartment A Policy defined in root compartment: Allow group admins to manage instance-family in compartment Ops: Test: A After the compartment move, which action will provide users of group G1 and admins with similar privileges as before the move?

Define the following policy in compartment Dev:
Allow group G1 to manage instance-family in compartment A

Define the following policies in compartment Dev:
Allow group G1 to manage instance-family in compartment A
Allow group admins to manage instance-family in compartment Ops: Dev: A

Define the following policy in compartment: Dev:
Allow group admins to manage instance-family in compartment Ops: Dev: A

Mo change in any policy statement is required as all the policies associated with a compartment being moved is automatically updated

NEW QUESTION 17
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?

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.

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.

Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the Internet Gateway.

NEW QUESTION 20
You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu-frankfurt-1 region. The compute instances do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have enabled monitoring on the instances.
What could be wrong in this situation?

You need to assign a reserved public IP address to the compute instances.

You need to set up a Service Gateway to send metrics to the OCI Monitoring service.

Autoscaling only works for instances with public IP addresses.

Autoscaling only works with single availability domains.
