You are using the Oracle Cloud Infrastructure Command Line Interface to launch a Linux virtual machine. You enter the following command (with correct values for all parameters):

The command fails.
Which is NOT a valid parameter in this command?

• A. --subnet-id <subnet_id>
• B. -t <tenancy_id>
• C. --shape "<shape_name>"
• D. --image-id <image_id>
• E. -c <compartment_id>

You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute instances that are deployed private subnet. The Compute instances have an attached Network Security Group with a Source Type: Network security Group (NSG) , Source NSG: -050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:

However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host.
What is the root cause of this issue?

• A. All compute instances associated with NSG-050504 are also able to connect to the bastion host.
• B. A netmask of /32 allows all IP address in the 140.19.2.0 network, other than your IP 110.19.2.140
• C. The Security List allows access to all IP address which overrides the Network Security Group ingress rules.
• D. The port 22 provides unrestricted access to 140.19.2.140 and to other IP address

One of the compute Instances that you have deployed Is malfunctioning. You have created a console connection to remotely troubleshoot.
Which two statements about console connections are true?

• A. For security purpose, the console connection will not let you edit system configuration files.
• B. VNC console connection uses SSH port forwarding to create a secure connection from your local system to the VNC server attached to your instance's console.
• C. It is not possible to connect to the serial console to an Instance running Microsoft Windows, however VNC console connection can be used.
• D. It is not possible to use VNC console connections to connect to Bare Metal Instances.
• E. If you do not disconnect from the session, your serial console connection will automatically be terminated after 24 hours.

You are using Oracle Cloud Infrastructure (OCI) console to set up an alarm on a budget to track your OCI spending. Which two are valid targets for creating a budget In OCI?

• A. Select user as the type of target for your budget.
• B. Select Compartment as the type of target for your budget.
• C. Select Cost-Tracking Tags as the type of target for your budget.
• D. Select Tenancy as the type of target for your budget.
• E. Select group as the type of target for your budget.

You have recently Joined a startup company and quickly find that nobody is tracking the amount of money spent on Oracle Cloud Infrastructure (OCI). Seeing an opportunity to help save money you begin creating a solution to better track the cost of resources provisioned by each individual on the team.
Which option allows you to identify excessive spend across all resources in your tenancy?

• A. Use the Python SDK to write a custom application that will monitor the Audit Log. Look for CREATE events and configure the application to send you an email each time a new resource is created.
• B. Create a budget for each compartment that will send a notification when monthly spend reaches a pre-defined amount.
• C. Use the Events Service and create rules that will act when a new Object Storage bucket or Compute Instance has been created. Have the rule email you each time one of these events occurs.
• D. Create a tag namespace named BILLING with a Tag Key named CostCenter. Tag each of your resources with this Tag Key and the correct value.
