SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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 SysOps administrator needs to deploy a new application version to an Auto Scaling group without causing any downtime. The application runs on EC2 instances behind an Application Load Balancer. Which deployment method should the administrator use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a rolling update with a batch size of 1 instance and enable the health check grace period.
Option C is correct because a rolling update with a batch size of 1 instance at a time minimizes impact and can be done without downtime if health checks are configured. Option A is incorrect because it does not use Auto Scaling. Option B is incorrect because it terminates all instances at once. Option D is incorrect because immutable updates launch new instances in a new Auto Scaling group, which is also zero-downtime but not the only option.
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.
✗
Perform an in-place update by updating the launch template and manually replacing instances one by one.
Why it's wrong here
Manual replacement is not automated and may cause downtime if not done carefully.
✗
Use a rolling update with a batch size of 100% of the instances.
Why it's wrong here
Replacing all instances at once causes downtime.
✓
Use a rolling update with a batch size of 1 instance and enable the health check grace period.
Why this is correct
This replaces one instance at a time, maintaining capacity and availability.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a new Auto Scaling group with the new launch template and gradually shift traffic using a load balancer target group.
Why it's wrong here
This is a blue/green deployment which is also zero-downtime but requires additional setup; rolling update is 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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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 SOA-C02 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Use a rolling update with a batch size of 1 instance and enable the health check grace period. — Option C is correct because a rolling update with a batch size of 1 instance at a time minimizes impact and can be done without downtime if health checks are configured. Option A is incorrect because it does not use Auto Scaling. Option B is incorrect because it terminates all instances at once. Option D is incorrect because immutable updates launch new instances in a new Auto Scaling group, which is also zero-downtime but not the only option.
