I thought the eLER always gets a label of 0, so B makes sense to me.

I thought the eLER should receive packets with a specific label, but I can't remember if it was 0 or 3. This is tricky!

Okay, let's think this through step-by-step. The key is understanding what happens to the packet at the penultimate router and the eLER.

Okay, I think I've got this. Based on the description, the two capabilities I would recommend are Intelligent Document Automation to automatically capture the data from the faxed documents, and Care Authorizations to manage the approval process. Those seem like the most relevant options.

Option D is the way to go, the penultimate router has to pop that top label, no doubt about it.
