Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
A server inside a private network must always be reachable from the internet through the same public IPv4 address. Which NAT type best fits this requirement?
- Dynamic NAT only
- SNMP trap
- STP
- Static NAT
Dynamic NAT only — Dynamic NAT uses a pool and does not guarantee the same public address for a specific server.
SNMP trap — An SNMP trap is a notification and does not create public reachability.
STP — STP prevents Layer 2 loops and does not translate addresses.
Static NAT — Static NAT creates a consistent one-to-one mapping between an inside address and a public address.
