Correct answer & explanation
✓
Deploy the web application on Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones, with an Application Load Balancer
To achieve high availability and scalability for the web application, the company should deploy the web tier across multiple Availability Zones using an Auto Scaling group with an Application Load Balancer (Option A), which distributes traffic and automatically scales instances. For the MySQL database, using Multi-AZ Amazon RDS (Option C) provides automatic failover and high availability. Option B (single RDS instance) is a single point of failure. Option D (ElastiCache) is for caching, not for high availability or scaling. Option E (large EC2 instance with Elastic IP) does not provide scalability or availability.

Why this is correct
Multi-AZ provides automatic failover and high availability for the database.

Use Amazon ElastiCache to cache database queries
Why it's wrong here
ElastiCache improves performance but does not provide high availability or scalability for the application.
