PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is deploying SAP on AWS and needs to ensure high availability for the SAP application servers. Which TWO strategies can be used to achieve this? (Choose TWO.)
⚠ Common exam trap
Many candidates confuse the database tier (where Multi-AZ is appropriate) with the application tier, or mistakenly think that a single large instance with an Elastic IP provides high availability, when in fact it creates a single point of failure.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an Auto Scaling group with an Application Load Balancer
Options C and E are correct. Option C uses an Auto Scaling group with an Application Load Balancer to automatically distribute traffic across multiple SAP application server instances and replace failed ones, ensuring high availability. Option E deploys application servers in multiple Availability Zones to eliminate a single point of failure, as AZs are independent failure domains. Both strategies are recommended for SAP on AWS.
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 Amazon RDS Multi-AZ for the application tier
Why it's wrong here
RDS is for databases, not application servers.
- ✗
Use a single large EC2 instance with an Elastic IP
Why it's wrong here
Single point of failure.
- ✓
Use an Auto Scaling group with an Application Load Balancer
Why this is correct
An Auto Scaling group combined with an Application Load Balancer (ALB) automatically distributes incoming traffic across multiple SAP application server instances and replaces failed instances. The ALB performs health checks and routes traffic only to healthy instances, while Auto Scaling maintains the desired instance count across Availability Zones.
- ✗
Attach the same EBS volume to multiple instances
Why it's wrong here
EBS Multi-Attach is for clustered databases, not application servers.
- ✓
Deploy application servers in multiple Availability Zones
Why this is correct
Deploying application servers in multiple Availability Zones (AZs) ensures that if one AZ fails, the application servers in other AZs remain available. This eliminates a single point of failure and is a foundational high-availability strategy for SAP on AWS.
