Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q12-Q17):

NEW QUESTION # 12
Which components are required for establishing remote peering between two Virtual Cloud Networks (VCNs) in Oracle Cloud Infrastructure (OCI)?

  • A. Two VCNs with nonoverlapping CIDRS in different regions, a dynamic routing gateway (DRG) attached to each VCN, a remote peering connection (RPC) on each DRG, and a connection established between the RPCs.
  • B. Two VCNs with overlapping CIDRS in different regions, a virtual private network (VPN) gateway attached to each VCN, and a direct connection between the VPN gateways.
  • C. Two VCNs with nonoverlapping CIDRS in the same region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGs.
  • D. A single VCN with nonoverlapping CIDRS in each region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGS.

Answer: A

Explanation:
Remote peering in Oracle Cloud Infrastructure allows two VCNs in different regions to communicate securely. To establish remote peering, the following components are required:
Two VCNs with Nonoverlapping CIDRs:
The CIDR blocks of the two VCNs must not overlap. This is crucial to avoid routing conflicts and ensure that traffic is correctly routed between the VCNs.
Dynamic Routing Gateway (DRG) Attached to Each VCN:
A DRG is a virtual router that provides a path for traffic between the VCN and networks outside the VCN, such as other VCNs via remote peering, on-premises networks, or other cloud services. Each VCN needs its own DRG.
Remote Peering Connection (RPC):
An RPC is a specialized connection on the DRG used specifically for remote peering. You need to create an RPC on each DRG associated with the VCNs you wish to peer.
Connection Between RPCs:
Finally, a connection must be established between the RPCs of the two DRGs. This connection facilitates the secure and private exchange of traffic between the VCNs over Oracle's backbone network.
Incorrect Options:
Option A involves a single VCN, which does not fulfill the requirement of remote peering between two VCNs.
Option B involves overlapping CIDRs and VPN gateways, which are incorrect for remote peering.
Option C suggests peering within the same region, which would be considered local peering rather than remote peering.
Relevant OCI Documentation:
OCI Remote VCN Peering
Dynamic Routing Gateway (DRG) Overview
These resources provide a detailed guide on configuring remote peering in OCI, ensuring secure and effective communication between VCNs across regions.


NEW QUESTION # 13
Which TWO are key benefits of setting up Site-to-Site VPN on Oracle Cloud Infrastructure (OCI)?

  • A. When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP).
  • B. When setting up Site-to-Site VPN, it creates a private connection that provides consistent network experience.
  • C. When setting up Site-to-Site VPN, customers can expect bandwidth above 2 Gbps.
  • D. When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels.

Answer: A,D

Explanation:
Setting up a Site-to-Site VPN on Oracle Cloud Infrastructure offers several key benefits related to connectivity and reliability:
Static or Dynamic Routing (BGP): OCI allows customers to configure Site-to-Site VPN with either static routing or dynamic routing using Border Gateway Protocol (BGP). This flexibility enables customers to choose the routing method that best suits their network configuration and requirements.
Redundant VPN Tunnels: OCI automatically provisions redundant VPN tunnels when you set up a Site-to-Site VPN. These redundant tunnels ensure high availability and fault tolerance, so if one tunnel fails, traffic can continue to flow through the other tunnel without interruption.
Bandwidth Considerations: While the VPN provides a reliable connection, it typically does not exceed 2 Gbps in bandwidth. Higher bandwidth connections usually require FastConnect.
Private Connection: The VPN does create a secure and private connection between on-premises data centers and OCI, but it does not inherently provide a consistent network experience in the way that a dedicated connection like FastConnect does.
Relevant OCI Documentation:
Site-to-Site VPN Overview
Configuring Routing for VPNs
These references detail the benefits and technical specifications of setting up Site-to-Site VPNs on OCI.


NEW QUESTION # 14
Which Traffic Management Steering Policy facilitates the distribution of DNS traffic based on the geographical location of end users?

  • A. Geolocation Steering
  • B. IP Prefix Steering
  • C. Proximity Steering
  • D. ASN Steering

Answer: A

Explanation:
Geolocation Steering in OCI's Traffic Management Steering Policy allows you to distribute DNS traffic based on the geographical location of the end users. This method helps direct users to the nearest regional endpoint, optimizing latency and improving user experience.
Use Cases: Geolocation Steering is commonly used to deliver region-specific content, comply with data residency laws, or optimize service performance by directing traffic to the closest available servers.

Oracle Cloud Infrastructure Documentation: Traffic Management Steering Policies


NEW QUESTION # 15
Why was SSH still possible after port 22 was removed from the Security Lists?

  • A. The VCN where that compute instance resides still has a route rule.
  • B. The VNIC of that compute instance is attached to a Cluster Network.
  • C. The VNIC of that compute instance is attached to a Network Security Group (NSG).
  • D. The VCN where that compute instance resides still has an Internet Gateway.

Answer: C

Explanation:
Even after removing port 22 from the Security Lists, SSH was still possible because the Virtual Network Interface Card (VNIC) of the compute instance is attached to a Network Security Group (NSG).
NSGs: NSGs provide a more flexible and granular way to manage security rules compared to Security Lists. They allow you to apply security rules directly to VNICs associated with resources such as compute instances. If an NSG allows traffic on port 22, SSH will still be possible, regardless of the Security List settings.

Oracle Cloud Infrastructure Documentation: Security Lists and Network Security Groups


NEW QUESTION # 16
How will moving a database instance to a different compartment impact user access?

  • A. Access will be revoked for all users.
  • B. IAM policies are not tied to compartments.
  • C. Compartments are not covered by IAM policies.
  • D. Compartments prevent resource movement.

Answer: A

Explanation:
In Oracle Cloud Infrastructure (OCI), when you move a database instance to a different compartment, the following impact on user access occurs:
Impact of Moving Resources: When you move a resource, like a database instance, to a different compartment, the IAM policies that grant access to that resource in the original compartment no longer apply. This effectively revokes access for users or groups unless equivalent policies are in place in the new compartment.
Restoring Access: To restore access, you would need to create new IAM policies in the destination compartment that grant the necessary permissions to the users or groups who need access.
Relevant OCI Documentation:
Managing Compartments
Moving Resources
These resources provide detailed steps on how compartment changes impact resource access and management.
