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 is migrating from a legacy MPLS network to AWS using Direct Connect. The network team wants to ensure high availability with a backup connection. They have two Direct Connect connections from different providers, both terminating at the same AWS Direct Connect location. Which configuration provides the most resilient setup?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use both connections with separate virtual interfaces, each terminating on different customer routers.
Option D is correct. Using two different devices and separate virtual interfaces provides redundancy at both the physical and logical level. Option A is wrong because a single device is a single point of failure. Option B is wrong because a single VIF is a single point of failure. Option C is wrong because using the same provider reduces diversity.
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.
✗
Use both connections but from the same provider to simplify management.
Why it's wrong here
Provider failure takes down both.
✓
Use both connections with separate virtual interfaces, each terminating on different customer routers.
Why this is correct
Full redundancy with diverse paths.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use one connection with two virtual interfaces for redundancy.
Why it's wrong here
Single physical connection is a SPOF.
✗
Use both connections with a single virtual interface on each, but terminate on the same router.
Why it's wrong here
Same router failure affects both.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
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.

What is the correct answer to this question?
The correct answer is: Use both connections with separate virtual interfaces, each terminating on different customer routers. — Option D is correct. Using two different devices and separate virtual interfaces provides redundancy at both the physical and logical level. Option A is wrong because a single device is a single point of failure. Option B is wrong because a single VIF is a single point of failure. Option C is wrong because using the same provider reduces diversity.
