Wait, is a landline number one of the possible reasons? I'm not sure I fully understand how SMS messaging works across different types of phone numbers. I'll need to double-check that before answering.

Okay, I've got this. The key things that can prevent an SMS from reaching a mobile are if the phone is switched off, if it's out of network coverage, or if the user is already on another call. I'll select those three options.

Hmm, this looks like a tricky VXLAN question. I'll need to carefully review the options and think through the VXLAN multicast encapsulation and decapsulation process.
