Question 1

You have been asked to ensure that in-transit communication between an Oracle Cloud
Infrastructure (OCI) compute instance and an on-premises server (192.168.10.10/32) is encrypted.
The instances communicate using HTTP. The OCI Virtual Cloud Network (VCN) is connected to the on-
premises network by two separate connections: a Dynamic IPsec VPN tunnel and a FastConnect
virtual circuit. No static configuration has been added.
What solution should you recommend? (Choose the best answer.)

  • A. It is not possible to use VNC console connections to connect to Bare Metal Instances.
  • A. The instances will communicate by default over IPsec VPN, which ensures data is encrypted in- transit.
  • B. VNC console connection uses SSH port forwarding to create a secure connection from your local system to the VNC server attached to your instances console.
  • B. Advertise a 192.168.10.10/32 route over the VPN.
  • C. It is not possible to connect to the serial console to an instance running Microsoft Windows, however VNC console connection can be used.
  • C. Advertise a 192.168.10.10/32 router over the FastConnect.
  • D. For security purpose, the console connection will not let you edit system configuration files.
  • D. The instances will communicate by default over the FastConnect private virtual circuit, which ensures data is encrypted in-transit.
  • E. If you do not disconnect from the session, your serial console connection will automatically be terminated after 24 hours.

Question 8

You are asked to deploy a new application that has been designed to scale horizontally. The business
stakeholders have asked that the application be deployed in us-phoenix-1.
Normal usage requires 2 OCPUs. You expect to have few spikes during the week, that will require up
to 4 OCPUs, and a major usage uptick at the end of each month that will require 8 OCPUs.

Question 12

Your company recently adopted a hybrid cloud architecture which requires them to migrate some of
their on- premises web applications to Oracle Cloud Infrastructure (OCI). You created a Terraform
template which automatically provisions OCI resources such as compute instances, load balancer,
and a database instance. After running the stack using the terraform apply command, it successfully
launched the compute instances and the load balancer, but it failed to create a new database
instance with the following error:
Service error: NotAuthorizedOrNotFound. shape VM.Standard2.4 not found. http status code: 404
You discovered that the resource quotas assigned to your compartment prevent you from using
VM.Standard2.4 instance shapes available in your tenancy. You edit the Terraform script and replace
the shape with VM.Standard2.2
Which option would you recommend to re-run the terraform command to have required OCI
resources provisioned with the least effort? (Choose the best answer.)

  • A. Create a Cost-Tracking tag. Apply this tag to all resources with team information. Use the OCI cost analysis tools to filter costs by tags.
  • A. terraform plan –target=oci_database_db_system.db_system
  • B. Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.
  • B. terraform apply –auto-approve
  • C. Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.
  • C. terraform refresh –target=oci_database_db_system.db_system
  • D. Define and use tags for resources used by each team. Analyze usage data from the OCI Usage Report which has detailed information about resources and tags.
  • D. terraform apply –target=oci_database_db_system.db_system
