A company is migrating a multi-tier application to the cloud. The application has a web tier, an application tier, and a database tier. The web tier must be accessible from the internet, the application tier should only be accessible from the web tier, and the database tier should only be accessible from the application tier. The company wants to ensure high availability and performance. What network architecture should they use?

Use a single subnet with network ACLs to restrict traffic

Place each tier in a separate subnet, with security groups controlling traffic between them, and use a load balancer for the web tier

Place all tiers in the same subnet and rely on security groups to restrict traffic

Place the web and application tiers in the same subnet and the database in a separate subnet

A company is migrating a customer relationship management (CRM) application to the cloud. The application has a predictable usage pattern: high traffic during business hours and low traffic at night. The company wants to optimize cost without sacrificing performance. Which cloud deployment model is most suitable?

A serverless function that runs the entire application

A containerized application with auto-scaling based on demand

A VM that is manually scaled up during peak hours

A single large VM that can handle peak traffic

A company is migrating a development and test environment to the cloud. The environment is used only during business hours (9 AM to 5 PM, Monday to Friday). The company wants to minimize compute costs. What should they do?

Move to a serverless architecture

Use reserved instances for all VMs

Use a scheduled shutdown of VMs during off-hours

A company is migrating a web application to the cloud. The application has a variable workload: it experiences spikes during product launches and other marketing events. The company wants to minimize cost while ensuring the application can handle the spikes. What should they do?

Use spot instances for all capacity

Use a combination of reserved instances for baseline capacity and on-demand instances for spikes

Use only reserved instances to get the lowest price

Use only on-demand instances to avoid any upfront commitment

Which factor is most important when deciding between online transfer and physical shipment for data migration?

The color of the storage device

The number of users in the organization

The total size of the data and the available network bandwidth
