문제2
Your deployment platform within Oracle Cloud Infrastructure (OCI) leverages a compute instance with multiple block volumes attached. There are multiple teams that use the same compute instance and have access to these block volumes. You want to ensure that no one accidentally deletes any of these block volumes. You have started to construct the following IAM policy but need to determine which permissions should be used. allow group DeploymentUsers to manage volume-family where ANY { request.permission != <???>, request.permission != <???>, request.permission != <???> } Which permissions can you use in place of <???> in this policy? (Choose the best answer.)

SIMULATION
Scenario: 2 (Oracle Cloud-init and AutoScaling: Use cloud-init to Configure Apache on Instances in an Autoscaling Instance Pool) Scenario Description: (Hands-On Performance Exam Certification) You're deploying an Apache-based web application on OCI that requires horizontal autoscaling.
To configure instances upon provisioning, write a cloud-init script for Oracle Linux 8 that installs and enables Apache (httpd), and opens the firewall for HTTP on TCP port 80. Create an instance configuration and include the cloud-init script in it. Use this instance configuration to create an instance pool and autoscaling configuration.
Pre-Configuration:
To fulfill this requirement, you are provided with the following:
Access to an OCI tenancy, an assigned compartment, and OCI credentials
A VCN Cloud-Init Challenge VCN with an Internet gateway and a public subnet. The security list for the subnet allows ingress via TCP ports 22 and 80 (SSH and HTTP). The route table forwards all egress to the Internet gateway.
Access to the OCI Console
Required IAM policies
An SSH key pair for the compute instance
Public Key https://objectstorage.us-ashburn-1.oraclecloud.com/n/tenancyname/b/PBT_Storage/o/PublicKey.pub Private Key https://objectstorage.us-ashburn-1.oraclecloud.com/n/tenancyname/b/PBT_Storage/o/PKey.key Note: Throughout your exam, ensure to use assigned Compartment , User Name , and Region.

문제6
You set up a bastion host in your Virtual Cloud Network (VCN) to allow only your IP ad-dress (140.19.2.140) to establish SSH connections with your compute instances that are deployed in a private subnet. The compute instances have an attached Network Security Group (NSG) with a Source Type: Network Security Group (NSG), Source NSG: NSG-050504. To secure the bastion host, you add the following ingress rules to its NSG: Type: All TCP Proto-col: TCP Port Range: 22 Source: 140.19.2.140/32 Type: All TCP Protocol: TCP Port Range: 22 Source: NSG-050504 However, when you check the bastion host logs, you discover that there are IP addresses other than your own that can access your bastion host. What is the root cause of this issue?

You have a group of developers who launch multiple VM.Standard3.Flex compute in-stances every day into the compartment Dev. As a result, your Oracle Cloud Infrastructure (OCI) tenancy quickly hits the service limit for this shape, and other groups can no longer create new instances using the VM.Standard3.Flex shape. Therefore, your company issues a new mandate that the Dev compartment must include a quota that allows the use of only 20 VM.Standard3.Flex OCPUs per availability domain, without affecting any other compartment in the tenancy. Which quota statement would you use to implement this new requirement?
