Early today, Packetfront called me for an interview. Here were the technical questions that they asked me. Apparently out of the 10+ interviews that they had last week, only about 2 of them made the cut.
difference between bridge and router --uh, easy..."bridge segments your network via MAC addresses; a router segments via subnets." He seemed happy with this and quickly moved on. difference between RIP and OSPF --uh, also easy. "I'm assuming you mean RIP2. OSPF is hierarchy-based and takes into account how fast each hop is, unlike RIP. But RIP2 does everything I need in my small biz networks." He moved on quickly here also. difference between OSPF and BPG --"I haven't had to work with BGP, but I've done stuff with OSPF in real life and in lab environments. The one time I had to worry about redundancy in a multi-homed environment, I just had my client buy extra software on their F5s that allowed them to route around whatever carrier line was hosed. If I had it to do all over again, I'd probably look into some of the other link aggregation solutions out there." which field in the packet was responsible for QoS --I told them I didn't know, but I suspect that this sort of question is like "Who is buried in Grant's Tomb?" (I haven't googled for an answer yet) Apparently, I made the first cut and territory managers are going to be calling me.
