What Are the Technical Requirements for Using CompTIA CertMaster Labs?

Connectivity Requirements

To launch and use a lab, the following requirements must be met:

1. Use a supported operating system.
   1. Windows 7 or later.
   2. Ubuntu 14.04 or later (or comparable distribution).
   3. macOS 10.12 or later.
2. Have a supported browser like Edge, Chrome, Firefox or Safari.
   1. The latest version is preferred, but full support details can be found below.
   2. Chromium-based browsers like Opera or Vivaldi can connect, but default hotkeys they set may interfere with lab inputs.
3. Be connected to a network that allows at least one of the following:
   1. Secure Web sockets on HTTPS port 443 and 43443.
   2. RDP over port 21xxx or 443 (enhanced control).

Bandwidth Requirements

In addition to the software requirements above, we recommend the following:

1. Minimum 200kbps consistent bandwidth with 1mbps burst per student.
   1. Machine controller bandwidth consumption is based on the rate onscreen content changes, some scenarios (i.e. web browsing inside the lab) may require more.
   2. For an optimal experience, we recommend at least 1mbps per student.
2. When utilizing the instructions interface, bandwidth needs may increase based on what features are utilized. Examples include:
   1. Embedded audio
   2. Embedded video
   3. Large numbers of embedded images
   4. Bandwidth usage is highly dependent on the media being used. An embedded MP3 may fit into 1mbps burst capacity, while a 1080P video can require up to 10mbps for its duration.
3. When using Cloud Slice labs where the target environment is a website, additional bandwidth may be required.
   1. For the Azure and AWS management portals, we recommend at least 512kbps per student.
