Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Sample Questions (Q16-Q21):

NEW QUESTION # 16
To achieve high availability in a 2-node RAC DB System in Oracle Cloud Infrastructure, what would you use to distribute your nodes to provide database instance fault isolation?

A. Remote region
B. Local region
C. Availability Domains
D. Fault Domains

Answer: D

Explanation:
In a 2-node Real Application Clusters (RAC) DB System in OCI, Fault Domains (FDs) within a single Availability Domain (AD) are used to distribute nodes, ensuring fault isolation at the hardware level (e.g., separate racks/power). Availability Domains (Option A) provide broader isolation but are overkill for a 2-node setup within one region. Local/Remote regions (Options B and D) are geographic, not instance-specific. Oracle's HA documentation recommends FDs for RAC.

NEW QUESTION # 17
what is the first and essential resource that needs to be created before establishing the Partner Interconnect VLAN attachment?

A. A Shared VPC in Google Cloud.
B. A Google Cloud Router with the appropriate ASN.
C. A Google Cloud Firewall Rule allowing BGP.
D. A Cross-Cloud Interconnect VLAN attachment.

Answer: B

Explanation:
Before you can create a Partner Interconnect VLAN attachment, you must have a Cloud Router in your Google Cloud project. This Cloud Router is essential because:
BGP Peering: The Cloud Router is responsible for establishing BGP (Border Gateway Protocol) peering with the partner's network, which in turn connects to Oracle Cloud. The VLAN attachment provides the Layer 2 connectivity over which the BGP sessions run.
ASN (Autonomous System Number): The Cloud Router needs to be configured with your Google Cloud project's ASN (Autonomous System Number). This ASN is used in the BGP sessions to identify your network.
Why the other options are incorrect:
B). A Cross-Cloud Interconnect VLAN attachment. This option is incorrect because Partner Interconnect is the correct term for connecting with Oracle. Cross-Cloud Interconnect is used for connecting to other Google Cloud regions. Also, the VLAN attachment is created after the Cloud Router.
C). A Google Cloud Firewall Rule allowing BGP. While firewall rules are important for security, they are configured after the connection is established and the routing is working. The Cloud Router needs to exist first to even have a target for the firewall rules.
D). A Shared VPC in Google Cloud. Shared VPC is a Google Cloud organizational concept and is not directly related to establishing the Partner Interconnect connection itself. The interconnect works regardless of whether Shared VPC is used.

NEW QUESTION # 18
While configuring Oracle Interconnect for Google Cloud, which specific Interconnect Type must users select when creating a VLAN attachment on the Google Cloud Platform (GCP) console?

A. Cross-Cloud Interconnect Connection
B. Partner Interconnect Connection
C. VPN Interconnect Connection
D. Dedicated Interconnect Connection

Answer: B

Explanation:
For Oracle Interconnect for Google Cloud, users must select the Partner Interconnect Connection type when creating a VLAN attachment in the GCP console. This type integrates with OCI's FastConnect via a partner network, enabling private connectivity. "Cross-Cloud Interconnect" (Option B) is not a GCP term, Dedicated Interconnect (Option C) is for direct GCP connections, and VPN (Option D) is unrelated. Oracle's setup guide specifies Partner Interconnect for this multicloud link.

NEW QUESTION # 19
Which of the following actions requires coordination with Oracle support when working with Oracle Database@Google Cloud?

A. Backing up a PDB (Pluggable Database) to OCI Object Storage.
B. Applying database patches to a CDB (Container Database).
C. Creating a new database within an existing Exadata VM Cluster.
D. Scaling up the compute resources of an Exadata VM Cluster.

Answer: D

Explanation:
Here's a breakdown:
A). Creating a new database within an existing Exadata VM Cluster: This is a standard database administration task that customers can perform themselves using SQL*Plus, SQL Developer, or other database management tools. It doesn't require Oracle support.
C). Applying database patches to a CDB (Container Database): While patching requires careful planning and execution, it's generally a customer responsibility within Oracle Database@Google Cloud. Oracle provides the patches, but the application is typically handled by the customer's database administrators.
D). Backing up a PDB (Pluggable Database) to OCI Object Storage: While OCI Object Storage might be involved, the backup operation itself is a standard database administration task that the customer performs. Configuring backups to external storage might require initial setup, but the backups themselves don't necessitate ongoing Oracle support coordination.
B). Scaling up the compute resources of an Exadata VM Cluster: Scaling compute resources (like adding more compute nodes or increasing CPU/memory) involves changes to the underlying infrastructure provided by Oracle. This requires coordination with Oracle support because it's not a self-service operation through the Google Cloud console. It's a managed infrastructure change.

NEW QUESTION # 20
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 Shared Infrastructure with auto-scaling enabled.
B. Base Database on bare metal with manual scaling.
C. Base Database on a virtual machine with auto-scaling configured.
D. Autonomous Database on Dedicated Infrastructure with manual scaling.

Answer: A

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.
