Free AWS SAP-C02 Actual Exam Questions - Question 1 Discussion
data to the website, have the data processed, and have the data sent back to them in an email Data
is stored in a MySQL database running on an Amazon EC2 instance The database is running in a VPC
with two private subnets The website is running on Apache Tomcat in a single EC2 instance in a
different VPC with one public subnet There is a single VPC peering connection between the database
and website VPC.
The website has suffered several outages during the last month due to high traffic
Which actions should a solutions architect take to increase the reliability of the application? (Select
THREE.)
Makes sense to add Auto Scaling for traffic spikes, so A.
Probably F, adding AZ diversity helps if one zone fails.
Maybe F too, since adding a subnet in another AZ helps prevent outages if one zone goes down. B and E don’t really add much for high traffic or reliability in this case.
D imo, A and C are definitely solid picks here. Adding Auto Scaling and a load balancer (A) really tackles the website’s outages from traffic spikes. Moving the database to Aurora with a replica (C) adds a failover setup, which is key for reliability. For the third, I’d pick F because adding another public subnet in a different AZ helps with availability if one AZ goes down. B is overkill since one VPC peering connection is enough, and D doesn’t really impact outages directly but more about outbound internet traffic. E doesn’t solve the high traffic problem either.
A/C/F? Adding Auto Scaling and a load balancer for Tomcat is crucial to handle traffic, so A makes sense. Migrating to Aurora with a read replica (C) improves database availability too. For F, adding a public subnet in another AZ allows better fault tolerance for the website VPC, distributing instances across zones. B isn’t really needed since one VPC peering supports enough traffic. D and E don’t quite address the main reliability issues given the context.
Option A is a must to handle traffic spikes by scaling Tomcat servers automatically. B seems unnecessary since one VPC peering suffices. C also helps with database reliability thanks to Aurora's built-in replication.
