- A
Initiate VPC peering connection request, Accept VPC peering connection request, Add routes to route tables, Update security groups, Update network ACLs
This is the correct order because you must first request the peering connection, then the other VPC accepts, then you add routes to enable traffic, then adjust security groups, and finally network ACLs as the last layer of access control.
- B
Accept VPC peering connection request, Initiate VPC peering connection request, Add routes to route tables, Update security groups, Update network ACLs
Why wrong: This is incorrect because the acceptance must happen after the initiation request; the order of initiation and acceptance cannot be reversed.
- C
Initiate VPC peering connection request, Accept VPC peering connection request, Update security groups, Add routes to route tables, Update network ACLs
Why wrong: This is incorrect because routes must be added before updating security groups; otherwise, the route to the peered VPC does not exist, making security group updates ineffective for cross-VPC traffic.
- D
Initiate VPC peering connection request, Accept VPC peering connection request, Update network ACLs, Update security groups, Add routes to route tables
Why wrong: This is incorrect because routes must be added before both security groups and network ACLs, and network ACLs are typically updated after security groups as a final step.
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Drag and drop the steps to set up a cross-region VPC peering connection in the correct order.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Initiate VPC peering connection request, Accept VPC peering connection request, Add routes to route tables, Update security groups, Update network ACLs
First initiate, then accept, then add routes, then update security groups, and finally network ACLs.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Initiate VPC peering connection request, Accept VPC peering connection request, Add routes to route tables, Update security groups, Update network ACLs
Why this is correct
This is the correct order because you must first request the peering connection, then the other VPC accepts, then you add routes to enable traffic, then adjust security groups, and finally network ACLs as the last layer of access control.
Related concept
Standard ACLs match source addresses.
- ✗
Accept VPC peering connection request, Initiate VPC peering connection request, Add routes to route tables, Update security groups, Update network ACLs
Why it's wrong here
This is incorrect because the acceptance must happen after the initiation request; the order of initiation and acceptance cannot be reversed.
- ✗
Initiate VPC peering connection request, Accept VPC peering connection request, Update security groups, Add routes to route tables, Update network ACLs
Why it's wrong here
This is incorrect because routes must be added before updating security groups; otherwise, the route to the peered VPC does not exist, making security group updates ineffective for cross-VPC traffic.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SAP-C02 ACL questions on filtering logic and placement.
