PAS-C01 Technology Practice Question

Q: How is Technology tested on the PAS-C01 exam?

Technology — This question tests Technology — Read the scenario before looking for a memorised answer..

Q: What is the correct answer to this Technology PAS-C01 question?

The correct answer is: Deploy a second ASCS instance in a different Availability Zone, set up SAP enqueue replication, and use a virtual IP address with Route 53 health checks for failover. — Option C is correct because deploying a second ASCS instance in a different Availability Zone with SAP enqueue replication and a virtual IP address managed by Route 53 health checks provides automatic failover with an RTO under 15 minutes. This setup ensures that if the primary ASCS instance fails, the standby instance takes over quickly, maintaining enqueue state and minimizing downtime. Option A is wrong because an Application Load Balancer is not designed for SAP ASCS failover; it would not handle enqueue replication or virtual hostname. Option B is wrong because an Auto Scaling group with lifecycle hooks does not provide application-level clustering or enqueue state replication. Option D is wrong because CloudWatch EC2 Auto Recovery only restarts the instance in the same Availability Zone and does not address enqueue replication or cross-AZ failover, resulting in an RTO longer than 15 minutes.

Q: Why do candidates get Technology questions wrong on the PAS-C01 exam?

Identify which PAS-C01 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.

This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 running SAP Business Suite on AWS. The system includes a central services (ASCS) instance, a primary application server (PAS), and a database server running SAP HANA. The company recently experienced an outage when the EC2 instance hosting the ASCS instance failed due to a hardware issue. The system was down for 4 hours while the IT team manually recovered the ASCS instance from an AMI. The company wants to implement a highly available ASCS instance with automatic failover and a Recovery Time Objective (RTO) of less than 15 minutes. The system is currently running in a single Availability Zone. What should the company do to meet these requirements?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

A
Place the ASCS instance behind an Application Load Balancer and configure health checks.
Why wrong: Placing ASCS behind an ALB is not appropriate because ASCS uses a virtual IP and enqueue replication; ALB does not manage the enqueue state or provide the necessary failover mechanism.
B
Configure an Auto Scaling group for the ASCS instance with a minimum of 1 and maximum of 2, and use a lifecycle hook to attach an Elastic IP.
Why wrong: Auto Scaling group with lifecycle hook does not provide SAP HA; it does not handle enqueue table replication or virtual hostname failover.
C
Deploy a second ASCS instance in a different Availability Zone, set up SAP enqueue replication, and use a virtual IP address with Route 53 health checks for failover.
This is the correct approach: deploy a second ASCS in another AZ, use SAP enqueue replication, and use Route 53 health checks with a virtual IP to achieve automatic failover with RTO <15 minutes.
D
Enable CloudWatch EC2 Auto Recovery on the ASCS instance and configure it to start a new instance in a different AZ.
Why wrong: CloudWatch EC2 Auto Recovery can restart the instance but only in the same AZ and does not maintain enqueue state, so RTO would be longer and cross-AZ failover is not achieved.

Correct answer & explanation

✓

Deploy a second ASCS instance in a different Availability Zone, set up SAP enqueue replication, and use a virtual IP address with Route 53 health checks for failover.

Option C is correct because deploying a second ASCS instance in a different Availability Zone with SAP enqueue replication and a virtual IP address managed by Route 53 health checks provides automatic failover with an RTO under 15 minutes. This setup ensures that if the primary ASCS instance fails, the standby instance takes over quickly, maintaining enqueue state and minimizing downtime. Option A is wrong because an Application Load Balancer is not designed for SAP ASCS failover; it would not handle enqueue replication or virtual hostname. Option B is wrong because an Auto Scaling group with lifecycle hooks does not provide application-level clustering or enqueue state replication. Option D is wrong because CloudWatch EC2 Auto Recovery only restarts the instance in the same Availability Zone and does not address enqueue replication or cross-AZ failover, resulting in an RTO longer than 15 minutes.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
