With OCI's pricing of $0.0085 USD per Gigabyte for Outbound Data Transfer in North America, how much will they spend per month for 7 Petabytes of Outbound Data Transfer?
Correct Answer: A
To calculate the monthly cost for 7 Petabytes (PB) of outbound data transfer at a rate of $0.0085 per GB in North America: Calculation: 1 PB = 1,000,000 GB 7 PB = 7,000,000 GB Cost = 7,000,000 GB * $0.0085/GB = $59,500.00 Thus, the cost for 7 PB of outbound data transfer per month is $59,500.00.

Question 17
Which image option allows you to create identical instances with minimal effort?
Correct Answer: D
When you need to create identical instances with minimal effort, creating a custom image is the best option. Custom Images: A custom image captures the exact configuration of an instance, including the OS, software, configurations, and data. By using a custom image, you can easily replicate the same setup across multiple instances, ensuring consistency and reducing the need for manual configuration each time. Other Options: Bring Your Own Image: This allows you to import your custom OS image into OCI, but it's more suited for cases where you are migrating from another environment. Select an Image from the OCI Marketplace: This provides pre-configured images from Oracle or third parties, but they may require additional setup to match your specific requirements. Use Oracle-Provided Images: These are basic images provided by Oracle, which may not include the specific customizations you need. Relevant OCI Documentation: Custom Images Overview This resource explains how to create and use custom images for quickly deploying identical instances.
Question 18
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
Correct Answer: C,D
In Oracle Cloud Infrastructure (OCI), understanding how private IP addresses work is crucial for configuring network interfaces and managing instances within your Virtual Cloud Network (VCN). Primary VNIC and Private IP Address: When an instance is launched in OCI, it is attached to a Virtual Network Interface Card (VNIC). The primary VNIC, which is automatically created during the instance launch, is associated with a primary private IP address by default. This private IP address is essential for the instance to communicate within the VCN. The primary private IP address is automatically assigned and cannot be removed from the primary VNIC while the instance is running. This supports the statement C. Additional Private IPs: Contrary to statement B, each VNIC can indeed have multiple private IP addresses, but by default, the primary VNIC comes with only one primary private IP. You can manually add secondary private IPs if needed. However, the additional IPs are not assigned by default; hence, A is incorrect. Public IP Association: For instances requiring internet access, a public IP address can be optionally assigned to the private IP address if the instance is in a public subnet. This is critical for scenarios where an instance needs to communicate with the internet or external networks. This aligns with statement D.
