Exam CV0-003 topic 1 question 189 discussion

The main requirements for the applications are scalability and external access. Note that A. Load balancer enhances scalability by efficiently distributing incoming traffic across multiple servers, preventing any single server from becoming overwhelmed. As demand grows, new servers can be added seamlessly, ensuring consistent performance. This flexibility allows businesses to adapt to changing workloads and user demands effectively. B. A VPN prevents external access by encrypting data transmitted over the internet, making it unreadable to unauthorized users. It also masks your IP address, hiding your true location and identity from potential attackers. This combined protection ensures that sensitive information remains secure and inaccessible to external threats. Firewall is NOT required in this scenerio since it is essential for protecting networks and devices from unauthorized access and cyber threats by monitoring and controlling incoming and outgoing traffic based on predetermined security rules.

This question is poorly worded. External access can be the public internet, so not sure why people are saying VPN. They aren't wanting to extend on premise or have secure connectivity.

Load balancers can integrate with autoscaling and server health checks so that if a web server becomes unreachable, the load balancer will detect the failure and trigger an automatic replacement or recovery action. With load balancing, you can effortlessly achieve redundancy and scalability,

It said : The requirements for the applications are scalability and external access

A company isn't going to implement a firewall for moving something to the cloud. They want external access thus they would want to do this securely which means a VPN.

Why not A & F
