Free AWS SAA-C03 Actual Exam Questions – Solutions Architect Questions - Question 9 Discussion
application routes traffic to multiple application pages by using URL paths.
The company begins to experience large surges of traffic at unpredictable times. The traffic surges
cause the web application to experience issues and to occasionally become unavailable.
The company needs to make the web application more scalable to handle sudden increases in traffic.
Which solution will meet this requirement?
It’s A because only that option combines Auto Scaling with an ALB, which supports routing by URL path and can handle unexpected traffic spikes smoothly. The others either lack proper scaling or routing flexibility.
B tbh also works well since it uses ECS with managed scaling, which is great for unpredictable traffic, plus containers can spin up faster than full EC2 instances. The Network Load Balancer is a bit lower-level than ALB but still effective for distributing traffic. C and D don’t offer true auto scaling—just adding instances or alarms won’t handle sudden spikes as smoothly. A and B both scale automatically, but B’s container approach might provide quicker response times during bursts.
A. This option sets up Auto Scaling with multiple EC2 instances behind an ALB, which directly handles scaling and traffic distribution. The others don’t provide true automatic scaling or load balancing for surges.
This one feels tricky but seems like A fits best since it uses Auto Scaling and an ALB to handle sudden traffic surges. So, I’d go with A here.
