ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses AWS CloudWAN to build a global network connecting multiple VPCs and on-premises sites. The network team has configured a core network with a segment that includes VPCs in us-east-1 and eu-west-1. The team notices that traffic between VPCs in different regions is taking a suboptimal path, going through the internet instead of staying within the AWS global network. The team has verified that the core network attachments are correctly configured and that the route tables are propagated. What should the team do to ensure traffic stays within the AWS global network?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure both VPCs are attached to the same CloudWAN segment.
Option C is correct because CloudWAN uses segments and attachments; if the VPCs are not in the same segment, traffic may be routed through the internet. Option A is wrong because Transit Gateway is not needed when using CloudWAN. Option B is wrong because DX is for on-premises, not inter-region VPC traffic. Option D is wrong because VPC peering is not part of CloudWAN architecture.
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.
✗
Establish a VPC peering connection between the two VPCs.
Why it's wrong here
Incorrect: VPC peering is a separate mechanism and not integrated with CloudWAN.
✗
Set up an AWS Direct Connect gateway to route traffic between regions.
Why it's wrong here
Incorrect: Direct Connect is for on-premises connectivity, not inter-region VPC traffic.
✓
Ensure both VPCs are attached to the same CloudWAN segment.
Why this is correct
Correct: Same segment ensures traffic stays within CloudWAN and uses AWS global backbone.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a transit gateway in each region and peer them together.
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 ANS-C01 NAT questions on configuration and troubleshooting.
