Firewall PBQs: CompTIA Network+ (N10-009)
easyQuestion 1 of 3
You are configuring egress rules for a small office router. The office network (172.16.0.0/12) needs outbound HTTPS for business browsing and DNS for name resolution, but outbound Telnet (port 23) must be blocked — it was discovered that a legacy device was making outbound Telnet connections. Fix the rules.
