PAS-C01 Technology Practice Question
A company runs its SAP application on EC2 instances in a private subnet. The SAP application needs to access an on-premises database through a VPN connection. The company wants to improve network performance and reduce latency between the SAP application and the on-premises database. Which action should the company take?
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
✓
Set up AWS Direct Connect between the VPC and on-premises data center.
AWS Direct Connect provides a dedicated private network connection from on-premises to AWS, offering lower and consistent latency compared to VPN connections that traverse the internet. Option B is incorrect because increasing VPN bandwidth does not reduce latency; latency is primarily affected by distance and internet routing. Option C is incorrect because VPC Peering is used to connect two VPCs, not to connect a VPC to an on-premises network. Option D is incorrect because a NAT Gateway enables outbound internet access from private subnets and does not provide connectivity to on-premises databases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set up AWS Direct Connect between the VPC and on-premises data center.
Why this is correct
Direct Connect provides dedicated, low-latency connection.
- ✗
Increase the VPN tunnel bandwidth to 10 Gbps.
Why it's wrong here
VPN still uses internet, higher latency than Direct Connect.
- ✗
Create a VPC Peering connection to the on-premises network.
Why it's wrong here
VPC Peering is for VPC-to-VPC, not on-premises.
- ✗
Add a NAT Gateway to the private subnet.
Why it's wrong here
NAT Gateway is for internet access, not for on-premises connectivity.
