AWS ELB Assessment Test

An AWS ELB (Elastic Load Balancing) Assessment Test evaluates candidates for their proficiency in designing, configuring, and managing load balancers on Amazon Web Services. ELB plays a crucial role in distributing incoming application traffic across multiple targets, ensuring high availability, fault tolerance, and scalability. This assessment typically covers the following aspects:

1. Load Balancer Types: Testing candidates' understanding of different types of ELBs, including Classic Load Balancer (CLB), Application Load Balancer (ALB), and Network Load Balancer (NLB), and their use cases, features, and limitations.
2. Load Balancer Basics: Assessing candidates' knowledge of basic load balancer concepts, such as listener configurations, target groups, health checks, routing policies, and SSL termination.
3. ELB Architecture: Evaluating candidates' understanding of the underlying architecture of ELBs, including load balancer nodes, availability zones (AZs), backend instances, Elastic IP addresses (EIPs), and cross-zone load balancing.
4. Load Balancer Configuration: Testing candidates' proficiency in configuring ELBs, including setting up listeners, target groups, health checks, routing rules, access logs, security policies, and SSL certificates.
5. Health Monitoring and Auto Scaling: Assessing candidates' ability to configure health checks for backend instances, monitor target health, and trigger auto scaling actions based on health check results or traffic patterns to maintain application availability and performance.
6. Networking: Evaluating candidates' knowledge of networking configurations for ELBs, including VPC setup, subnets, security groups, network ACLs, internet-facing vs. internal load balancers, and cross-VPC load balancing.
7. Security: Testing candidates' understanding of security best practices for ELBs, including configuring security groups, SSL/TLS encryption, certificate management, access control policies, and protecting against common security threats like DDoS attacks.
8. Integration with AWS Services: Assessing candidates' familiarity with integrating ELBs with other AWS services, such as Amazon EC2, Auto Scaling groups, AWS Certificate Manager (ACM), AWS WAF (Web Application Firewall), AWS CloudFormation, AWS Lambda, and AWS CloudWatch for comprehensive application deployment and monitoring.
9. Performance Optimization: Evaluating candidates' ability to optimize ELB performance for low latency, high throughput, and efficient traffic distribution, including configuring connection settings, idle timeout, pre-warming, and optimizing backend instances.
10. Monitoring and Troubleshooting: Testing candidates' skills in monitoring ELB performance metrics, analyzing access logs, setting up CloudWatch alarms, and troubleshooting common issues related to load balancer configuration, health checks, target registration, and request routing.
11. Cost Management: Assessing candidates' understanding of cost implications and cost optimization strategies for ELBs, including pricing models, data transfer costs, instance types, load balancer scaling, and usage-based billing.

Overall, our AWS ELB Assessment Test measures candidates' knowledge, practical skills, and hands-on experience in designing, configuring, and managing load balancers on AWS, providing valuable insights into their capabilities.
