| A _____ is a smaller network, which is part of your VNET and is used for security and logical division of resources. | subnet |
| A ______ distributes new inbound flows based on IP/port that arrive on the frontend to backend pool instances, according to rules and health probes. Supports port forwarding of traffic to specific hosts, and outbound connectivity for backend VMs. | Load Balancer |
| A specific type of VNet gateway, consisting of 2 or more dedicated VMs that sends encrypted data between Azure and an on-prem network over the public internet using a secure tunnel. | VPN Gateway |
| An _____ is a load balancer that distributes inbound traffic based on details of the HTTP request, can route traffic to a specific machines based on URI, supports auto-scaling, end-to-end encryption, zone redundancy and multi-site hosting (up to 100) | Application Gateway |
| Stores a cached version of your application on an edge node. Provides better performance and improved user experience, scales to handle larger volumes of traffic, and protects your backend application from high loads. | Content Delivery Network (CDN) |
| A direct link between on-prem and Azure. Provides a private, secure, high-bandwidth, low-latency connection between Azure Cloud and on-prem resources. | ExpressRoute |
| Globally unique Azure namespace for your data in the Azure Cloud. | Storage Account |
| Blob (Binary Large Object) storage is organized into _______ within storage accounts. | containers |
| Versatile storage technology that can store any type of file, can support video and audio streaming, and can be used for writing log files, archives, backup, restore and DR. | Blob storage |
| Name the 3 types of Blob storage. | Block, Append, Page |
| Blob Types: For storing files up to 8TB. Any part of the file can be accessed at any time, for example a virtual hard drive. | Page |
| Blob Types: For storing text and binary data up to 4.7TB. Made up of individually managed blocks of data. | Block |
| Blob Types: Optimized for append operations. Works well for logging where data is constantly appended. | Append |
| Name the 3 Blob pricing tiers. | Hot, Cool, Archive |
| This blob pricing tier is has lower access times and higher costs, is intended for frequently accessed files. | Hot |
| This blob pricing tier has lower storage and higher access times. Data remains here for at least 30 days. | Cool |
| This blob pricing tier has the lowest costs and highest access times. | Archive |
| Name the 4 types of disk storage offered by Azure. | HDD, Standard SSD, Premium SSD, Ultra Disk |
