A media company stores petabytes of raw video footage in OCI Object Storage. This footage is rarely accessed after the first 30 days but must be retained for 5 years for legal reasons. To minimize costs, which storage tier should they use for the long-term retention?
Show answer details
Correct answer: C
Archive Storage is the lowest cost tier, designed for data that is rarely accessed and has long retention requirements. It has a retrieval time of hours, which fits the 'retained for legal reasons' scenario.
- 2
Which OCI networking component is used to establish a private connection between a VCN and an on-premises network that does NOT traverse the public internet?
Show answer details
Correct answer: B
OCI FastConnect provides a dedicated, private connection between your data center and OCI. It bypasses the public internet, offering higher bandwidth and lower latency compared to VPN.

A startup is deploying a new application and is unsure of the memory and CPU requirements. They want the ability to adjust the number of OCPUs and amount of RAM independently to optimize costs. Which compute instance type should they select?
Show answer details
Correct answer: B
Flexible Shapes (e.g., E3, E4 Flex) allow customers to customize the number of OCPUs and the amount of memory independently. This contrasts with fixed shapes where the CPU-to-memory ratio is locked.

You are configuring a Load Balancer for an e-commerce application. The application requires that a user's session remains connected to the same backend server for the duration of their shopping experience to maintain the cart state. What feature must you enable?
Show answer details
Correct answer: B
Session Persistence (often called Sticky Sessions) ensures that requests from a specific client are always routed to the same backend server, which is essential for stateful applications like shopping carts.
- 5
Your company wants to move their CapEx infrastructure costs to an OpEx model. They also want to bring their existing Oracle Database licenses to the cloud to reduce costs. Which OCI pricing model supports this requirement?
Show answer details
Correct answer: B
BYOL (Bring Your Own License) allows customers to apply their current on-premises Oracle licenses to OCI services (like Database or Analytics), resulting in a discounted rate since the license cost is already paid.
- 6
You are managing a highly sensitive workload. You need to ensure that the encryption keys used to protect your data are managed by your security team, not Oracle. However, you still want to use the native OCI Vault service. Which key management option should you choose?
Show answer details
Correct answer: B
Customer-Managed Keys in OCI Vault allow you to create, rotate, and manage the lifecycle of the Master Encryption Keys. Oracle manages the hardware (HSM), but you control the key material and usage.

A multinational financial institution requires a cloud deployment that guarantees data never leaves their primary country of operations due to strict regulatory compliance, yet they need the agility and pricing model of the public cloud. They also require low-latency connectivity to their existing on-premises mainframe systems. Which OCI deployment model best fits these specific requirements?
Show answer details
Correct answer: B
OCI Dedicated Region provides all the services of the public cloud (IaaS, PaaS, SaaS) within the customer's own data center. This satisfies the strict data residency requirement (data stays on-prem) and low-latency connectivity to mainframes, while offering the consumption-based pricing model of the cloud.

You are designing a highly available web application in the Frankfurt region (which has 3 Availability Domains). The application requires redundancy against the failure of an entire data center. How should you distribute the compute instances to achieve this with the highest fault tolerance?
Show answer details
Correct answer: B
Availability Domains (ADs) are physically isolated data centers within a region. Deploying across multiple ADs protects against the failure of a single AD (data center). Fault Domains only protect against rack/power failures within a single AD.
