The answer is to schedule the migration during off-peak hours to avoid high utilization. This is correct because an existing Direct Connect link already at 80% utilization during business hours has limited headroom; adding migration traffic would likely cause congestion and degrade production performance. By moving the data transfer to off-peak periods, you leverage the existing bandwidth without risking packet loss or latency spikes for critical workloads. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your ability to prioritize operational stability over technical complexity—common traps include jumping to increase bandwidth (which may require lengthy carrier lead times) or suggesting a VPN over the internet (which introduces latency and security risks for SAP data). Remember that Snowball is only appropriate for very large, offline data volumes, not for a manageable migration over a busy link. Memory tip: “Off-peak first, bandwidth last”—always exhaust scheduling solutions before scaling infrastructure.
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. 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.
A company is migrating an SAP system to AWS and wants to use an existing AWS Direct Connect connection for the migration. The on-premises network team reports that the Direct Connect link is consistently at 80% utilization during business hours. What should the company do to ensure a successful migration without impacting production traffic?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Schedule the migration during off-peak hours to avoid high utilization.
The correct approach is to schedule the migration during off-peak hours when the link utilization is lower to avoid congestion. Increasing bandwidth may not be feasible immediately. Using VPN over the internet may add latency and security concerns. Snowball is for large data volumes, but if the data volume is manageable, off-peak migration is simpler.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Increase the bandwidth of the Direct Connect link.
Why it's wrong here
May not be possible quickly and could be costly.
✗
Use AWS Site-to-Site VPN over the internet as an alternative.
Schedule the migration during off-peak hours to avoid high utilization.
Why this is correct
Off-peak hours ensure minimal impact on production traffic.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use AWS Snowball Edge to transfer the data physically.
Why it's wrong here
Snowball is for large data volumes, but if the data can be transferred over the network during off-peak, it's simpler.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
