1Z0-1072-25 Question 104
Select 2Your organization has two Virtual Cloud Networks (VCN-A and VCN-B) in the same region used by different departments and a third VCN (VCN-C) in a remote region. You need to enable communication between VCN-A and VCN-B with minimal latency, and also allow traffic to flow between the local region� VCNs and VCN-C over Oracle� private backbone. Which two actions must you take to achieve this goal? (Choose two.)
- A
Create a Local Peering Gateway (LPG) in VCN-A and VCN-B and update their route tables and security rules for local peering.
- B
Create a Dynamic Routing Gateway (DRG) in both VCN-A and VCN-B to set up local peering in the same region.
- C
Create a DRG in VCN-C� region and a DRG in the local region, then establish a remote peering connection between them.
- D
Use Local Peering Gateways in the remote region to interconnect with the local region� VCNs for remote peering.
- E
Attach each subnet directly to a DRG in the same region to enable local peering.
Show answer and explanation
Correct answers: A, C
Explanation
In this scenario, local peering gateways are used for communication between VCNs in the same region, while dynamic routing gateways are required for remote peering across regions. After creating the appropriate gateways, you must also configure route tables and security rules to allow inter-VCN traffic. For more details, refer to the Oracle Cloud Infrastructure Virtual Cloud Network (VCN) documentation on local and remote peering.
- A. Correct.
Option 1 is correct. For local peering between two VCNs in the same region, you must create a Local Peering Gateway (LPG) in each VCN and configure the necessary route rules and security lists to allow traffic. This approach keeps traffic within the Oracle Cloud Infrastructure backbone without requiring an external gateway like a DRG.
- B. Incorrect.
Option 2 is incorrect. A DRG is not required for local peering within the same region; an LPG is used instead. A DRG is typically used for connectivity to on-premises networks or remote VCNs in different regions.
- C. Correct.
Option 3 is correct. To peer VCNs across different regions (remote peering), each region requires its own DRG. You then establish a remote peering connection between these DRGs so VCN traffic can flow securely and remain on the Oracle backbone.
- D. Incorrect.
Option 4 is incorrect. Local Peering Gateways (LPGs) are only used for peering within the same region. Remote peering always requires DRGs in each region to facilitate cross-region communication.
- E. Incorrect.
Option 5 is incorrect. You do not connect subnets directly to a DRG for local peering. Instead, subnets route traffic to an LPG for local peering. DRGs serve a different purpose such as remote peering or on-prem connections.
