What can a packet filtering firewall also be called?

Show Suggested Answer Hide Answer
Suggested Answer: D

While neither CBK nor AIO3 use the term 'screening router,' they both discuss how the packet filtering capabilities of a router can be used to block traffic much like a packet filtering firewall. Krutz and Vine use this term on p. 90.

'A scanning router' is incorrect. This is a nonsense term to distract you.

'A shielding router' is incorrect. This is a nonsense term to distract you.

'A sniffing router' is incorrect. This is a nonsense term to distract you.

I’m a bit confused; I thought sniffing routers were related to packet analysis, not filtering.

I’m pretty confident that the correct term is screening router. It just makes sense with how they filter packets.

I feel like I've seen "scanning router" in some practice questions, but that doesn't sound right for this one.

I think I remember packet filtering firewalls being referred to as screening routers, but I'm not entirely sure.
