Networking
What does VPN stand for and what is it used for?
Virtual Private Network, used to securely connect to a network over the internet.
What is object storage best used for?
Storing large amounts of unstructured data like photos, videos, and backups.
What does a firewall do?
Monitors and filters network traffic to protect systems from unauthorized access.
What does “load balancing” do?
Distributes workloads evenly across multiple servers for better performance.
What does RDP stand for?
Remote Desktop Protocol.
What is a Direct Connect?
A dedicated, private connection between an organization’s network and a cloud provider.
What is block storage and where is it commonly used?
Storage divided into blocks; ideal for databases and operating systems.
What is encryption used for?
Protecting data by converting it into unreadable code for anyone without a key.
What is compression and why is it used?
Reducing file size to save storage and improve data transfer speed.
What does SSH stand for and what is it used for?
Secure Shell — used for securely managing remote servers via command line.
What does DNS do in cloud networking?
It translates domain names into IP addresses so computers can locate each other.
What is file storage and when is it preferred?
Data stored as files in folders — used for shared file access or smaller workloads.
What security feature does HTTPS add to websites?
It encrypts communication between browser and server using SSL/TLS.
What is deduplication?
Removing duplicate copies of data to save storage space.
What is meant by “common access types” in cloud computing?
The different ways users connect to the cloud, such as VPN, direct connect, or web portals.
What does SDN stand for and why is it important?
Software-Defined Networking allows network management through software rather than hardware
What does “capacity on demand” mean?
The ability to automatically scale storage space based on current needs.
What is the main function of a VPN in cloud security?
It creates a secure, encrypted tunnel for remote access to cloud resources.
What does “hot storage” refer to?
Frequently accessed data stored for quick retrieval.
How do administrators manage software-defined systems differently from traditional ones?
Through software interfaces rather than physical devices.
What protocol allows secure web browsing and protects data in transit?
HTTPS
What is software-defined storage (SDS)?
A storage architecture managed by software rather than hardware controls.
What’s the difference between authentication and authorization?
Authentication confirms identity; authorization determines access rights.
what does “cold storage” refer to?
Infrequently accessed data is stored cheaply for long-term retention.
What is the main advantage of software-defined technologies?
Flexibility and automation — allowing resources to be configured and managed quickly.
