Q1Domain Verified
In a microservices architecture deployed across multiple Availability Zones, what is the primary purpose of implementing a circuit breaker pattern?
To automatically scale the number of service instances based on CPU utilization
To encrypt all data in transit between microservices
To distribute incoming traffic evenly across all service instances
To prevent a cascade of failures when a dependent service becomes unresponsive
Q2Domain Verified
When designing a highly available web application on AWS, which combination of services provides the most fault-tolerant foundation for serving traffic?
A CloudFront distribution pointing directly to an S3 bucket hosting static content
An Application Load Balancer distributing traffic to EC2 instances in multiple Availability Zones
A Route 53 record set pointing to an EC2 instance in a single Region
A single EC2 instance in one Availability Zone with an Elastic IP address
Q3Domain Verified
A three-tier application uses an Auto Scaling Group for its web servers. The scaling policy is based on average CPU utilization. During a predictable traffic surge, users report slow performance, but CPU utilization never breaches the scaling threshold. What is the most likely architectural issue?
The scaling policy is using an inappropriate metric and a metric like Application Load Balancer request count per target would be better
The VPC does not have an internet gateway attached
The EC2 instances are using EBS-optimized volumes
The Auto Scaling Group's desired capacity is set too high
