. They are lightweight, start up in seconds, and have a "tried and true" reputation for passing exam-specific labs like the CCNP ENARSI Note for Users:

This specific file is a highly sought-after image. Let’s break down what this file actually is, what its naming convention means, and how to successfully deploy it in your virtual lab. What Does the Filename Mean?
Because it is a native Linux binary rather than a full virtual machine (like CSR1000v), it boots in seconds. This makes it ideal for rapid prototyping and iterative testing of complex configurations. Limitations: : Native deployment of IPsec VPNs, Dynamic Multipoint
It executes the Cisco IOS software code directly on top of the host Linux kernel.
Because there is no hardware emulation layer, IOU images are incredibly lightweight. A single router instance might consume as little as 50MB to 100MB of RAM. This efficiency allows a single mid-range computer to spin up massive topologies featuring 50, 100, or even more interconnected routers simultaneously. 3.

EVE-NG is currently one of the most popular platforms for hosting IOU images. Users upload the i86bi-linux-l3-adventerprisek9-15.4.2t.bin file to a specific directory within the EVE-NG virtual machine ( /opt/unetlab/addons/iol/bin/ ). After adjusting the file permissions and generating a valid license file ( iourc ), the image becomes available as a drag-and-drop node within the web-based topology designer.
