• Sharding

Question 2)
A reverse proxy can be used to serve what parts of a web application, leaving the rest to be handled by the web server?

• API calls

• Static files
• Application URLs

Question 3)
When internal applications or microservices are communicating across private IP spaces, _____ may be necessary.

• A content delivery network
• Private load balancing
• External client requests
• Public load balancing

Question 4)
Tools like load balancers, computing units, and storage are typically offered as part of which service model?

• PaaS
• SaaS
• DBaaS
• IaaS

Question 5)
What are some of the traits of a type-1 hypervisor? Select all that apply.

• Runs on bare metal servers
• Runs on top of an operating system
• More efficient
• Has a simple management console

Question 6)
The management, networking, deployment, and scaling of containers is handled through _____.

• An operating system

Question 7)
Which type of server will automatically collect static files from a web server when they change?

• In auto-scaling, the scalability is managed by the cloud provider, and the capacity increases or decreases according to the load.
• In horizontal scaling, you keep adding processing cores, RAM and storage in the server.

Question 9)
Using this type of storage, you can upload and download large or small files via an API, as well as make those files available to anyone for a specified amount of time.

• Object storage
• Redundant storage
• Database storage
