## **Additional Technical Considerations**

**Corporate or Managed Devices:**

* May require IT assistance for admin rights, firewall permissions, or proxy whitelisting.

**Not Supported:**

* Multiple monitors
* Virtual environments (VMware, Citrix, etc.)
* VPNs, screen recorders, and remote access tools

**Best Practices:**

* Close unnecessary background apps before launch
* Restart your system before the test
* Use a wired connection for better stability
* Keep webcam and microphone active and unobstructed

***

## **Quick System Check (Recommended)**

### **Internet Connection Check**

Before your exam, verify that your internet connection is stable and meets the required speed for proctored sessions.

* **Speed Test:**
  Run a quick test at [Talview Speed Test](https://speed.talview.com/) to ensure a **minimum speed of 5 Mbps** for both download and upload.
  > *Tip: A wired Ethernet connection provides better stability than Wi-Fi.*

### **Camera and Microphone Test**

Your device must have a working camera and microphone for identity verification and continuous monitoring during the test.

* **Hardware Check:**
  Visit [Talview Video Diagnostics](https://video-diagnostics.talview.org/App) to confirm your **camera, microphone, and system audio** are functioning properly.
  > *Ensure you allow all browser permission prompts for camera and microphone access.*

### **Run Diagnostics**

Launch Secure browser and run Diagnostics to check if any restricted applications are open. If you see the warning for applications being open, follow the instructions on screen and close the applications. This ensures smooth experience when attending the session in Secure Browser.
