Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Packet-tracer simulates packet processing through the firewall and Snort engine without transmitting physical packets.
Packet-tracer simulates packet processing through the firewall engine and Snort, but it does not actually transmit a real packet onto the physical wire, meaning it is a simulation tool.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Packet-tracer actually transmits physical packets out of the egress interface to test real network latency.
Why it's wrong here
Packet-tracer is purely a simulation tool and does not transmit actual packets onto the network.
- ✗
Packet-tracer bypasses the Snort inspection engine entirely.
Why it's wrong here
Packet-tracer can simulate Snort inspection behavior depending on the syntax flags used.
- ✓
Packet-tracer simulates packet processing through the firewall and Snort engine without transmitting physical packets.
Why this is correct
Packet-tracer is a simulation utility that traces virtual packets through the access control and inspection engines.
- ✗
Packet-tracer only works for encrypted IPsec VPN traffic.
Why it's wrong here
Packet-tracer works for all types of IPv4 and IPv6 traffic traversing the firewall.
