Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Sample Questions (Q40-Q45):

NEW QUESTION # 40
Suppose you have a highly sensitive dataset stored in an Autonomous Database. What is the BEST way to ensure that no data leaves the EU?

A. Select an EU region for your Autonomous Database deployment and enable customer-managed encryption keys.
B. Implement Transparent Data Encryption (TDE) with a customer-managed key.
C. Configure a Virtual Cloud Network (VCN) with a security list blocking all outbound traffic.
D. Use Data Masking to obfuscate sensitive data before it leaves the database.

Answer: A

Explanation:
Here's why:
EU Region Selection: Deploying the Autonomous Database in an EU region (e.g., Frankfurt, Amsterdam, Paris, Dublin) ensures that the data physically resides within the EU's geographical boundaries. This addresses data residency requirements directly.
Customer-Managed Encryption Keys (CMEK): Enabling CMEK gives you control over the encryption keys used to protect your data at rest. This provides an additional layer of security and helps you meet compliance requirements related to key management. It also ensures that even if someone were to somehow exfiltrate the encrypted data, they wouldn't be able to decrypt it without your keys, which reside in your control, presumably also within the EU.
Why the other options are less suitable:
a) Configure a Virtual Cloud Network (VCN) with a security list blocking all outbound traffic: While blocking all outbound traffic would prevent data from leaving the VCN, it would also make the database practically unusable. Applications and users would not be able to connect to it. This is an overly restrictive and impractical solution.
b) Use Data Masking to obfuscate sensitive data before it leaves the database: Data masking is useful for protecting sensitive data when it needs to be shared with non-production environments or third parties. However, it doesn't prevent data from leaving the EU. The masked data would still be subject to data residency regulations.
d) Implement Transparent Data Encryption (TDE) with a customer-managed key: TDE encrypts data at rest, which is a good security practice. Having a customer-managed key adds further control. However, TDE alone does not guarantee data residency. The data could still be stored in a non-EU region.

NEW QUESTION # 41
Which tasks are performed in the Azure portal when using Oracle Database@Azure?

A. Enabling Data Guard for database backups
B. Provisioning container and pluggable databases
C. Managing and maintaining Exadata VM cluster and infrastructure
D. Configuring Oracle database homes

Answer: C

Explanation:
In Oracle Database@Azure, the Azure portal is used for managing and maintaining Exadata VM clusters and infrastructure, aligning with its Azure-native management approach. Data Guard (Option A), database homes (Option B), and container/pluggable databases (Option D) are configured post-provisioning, often via database tools, not directly as portal tasks. Oracle's documentation specifies this infrastructure focus in Azure.

NEW QUESTION # 42
How do you ensure that traffic between your OCI VCN and Azure Virtual Network uses the interconnect and not the public internet?

A. Configure route tables in both OCI and Azure to prioritize routes through the interconnect.
B. Configure security lists in both OCI and Azure to block traffic over the internet.
C. Enable private peering between the VCN and the Virtual Network.
D. Disable public IP addresses on instances in both environments.

Answer: A

Explanation:
Here's why:
Route tables are the core mechanism for controlling network traffic flow within both OCI and Azure. To ensure traffic uses the interconnect (like FastConnect/ExpressRoute), you need to configure the route tables to direct traffic destined for the other cloud provider's address space through the interconnect.
OCI Route Tables: In OCI, you'd create a route rule in your VCN's route table that directs traffic destined for the Azure Virtual Network's address space (e.g., a specific CIDR block) to the Dynamic Routing Gateway (DRG) that is connected to your FastConnect circuit.
Azure Route Tables: In Azure, you'd configure a route in your Virtual Network's route table that directs traffic destined for the OCI VCN's address space to the ExpressRoute gateway.
By configuring these routes, you explicitly tell the networks to use the private, dedicated connection for communication between the two clouds.
Why the other options are not sufficient or correct:
A). Configure security lists in both OCI and Azure to block traffic over the internet: Security lists (or Network Security Groups in Azure) control access based on ports and protocols, but they don't control routing. Blocking internet traffic would prevent instances from accessing the internet, but it wouldn't force traffic to use the interconnect. The routing decision happens before the security list rules are evaluated.
C). Disable public IP addresses on instances in both environments: Disabling public IPs prevents direct internet access to the instances, but it doesn't guarantee that traffic will use the interconnect. Without proper routing, the instances wouldn't be able to communicate with each other at all.
D). Enable private peering between the VCN and the Virtual Network: "Private peering" is a general term and doesn't fully describe the required configuration. While the interconnect is a form of private peering, it's the route table configuration that actually directs traffic over that private connection. Simply enabling the interconnect isn't enough; you must configure the routing.

NEW QUESTION # 43
To minimize the cost of your Autonomous Database while ensuring it scales automatically to handle peak loads. Which configuration is MOST suitable?

A. Autonomous Database on Dedicated Infrastructure with manual scaling.
B. Base Database on bare metal with manual scaling.
C. Autonomous Database on Shared Infrastructure with auto-scaling enabled.
D. Base Database on a virtual machine with auto-scaling configured.

Answer: C

Explanation:
Here's why:
Shared Infrastructure: Using shared infrastructure is inherently more cost-effective than dedicated infrastructure. You share the underlying hardware resources with other users, which reduces your costs significantly.
Auto-scaling: Enabling auto-scaling allows the Autonomous Database to automatically adjust its compute and storage resources based on workload demands. This means you only pay for the resources you actually consume. During peak loads, the database scales up to handle the increased demand, and during periods of low activity, it scales down to minimize costs.
Why other options are less suitable:
a) Autonomous Database on Dedicated Infrastructure with manual scaling: Dedicated infrastructure is the most expensive option. Manual scaling requires manual intervention to adjust resources, which is not ideal for handling unpredictable peak loads and does not minimize cost automatically.
c) Base Database on a virtual machine with auto-scaling configured: While this offers some flexibility, it requires significantly more management overhead compared to Autonomous Database. You are responsible for managing the operating system, database software, backups, and other administrative tasks. Autonomous Database handles all of this for you.
d) Base Database on bare metal with manual scaling: Bare metal is the most expensive and least flexible option. Manual scaling makes it unsuitable for handling peak loads efficiently and cost-effectively.

NEW QUESTION # 44
Which is a database service that CANNOT be provisioned in the Oracle Public Cloud?

A. Exadata Database Service on Shared Infrastructure
B. Autonomous Database on Shared Infrastructure
C. Exadata Database Service on Dedicated Infrastructure
D. Autonomous Database on Dedicated Infrastructure

Answer: C

Explanation:
The "Oracle Public Cloud" typically refers to OCI's broadly accessible cloud services. Autonomous Database on Shared (Option A) and Dedicated Infrastructure (Option B) are available in OCI. However, Exadata Database Service on Dedicated Infrastructure (Option C) is not a standard offering in the public OCI context-it's tied to specific deployments like Database@Azure or on-premises Exadata, not the public cloud. Option D is fictitious. Oracle's documentation clarifies Exadata's dedicated nature outside standard public offerings.
