Question 220
An acceptance check at Copperline Studios has two requirements: (1) let several internal addresses consume a shared pool of public IPv4 addresses, and (2) classify an IOS syslog message with severity 7. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) Dynamic NAT allocates eligible public addresses from a configured pool to matching inside hosts. (2) Numeric severity 7 contains debug-level diagnostic detail below informational messages. Neither action is a substitute for the other.
Incorrect Answers
The second step covers (2), but the first addresses enforce an ingress traffic rate by dropping or remarking excess packets. Policing measures a rate and takes an immediate conform/exceed action without ordinary shaping buffers. It leaves outcome (1) unfulfilled.
Neither step is the requested pair: Build a standard NAT ACL matching only approved inside-local addresses is for restrict which source subnet is eligible for dynamic NAT, and Configure ip address dhcp on the WAN interface is for let a router obtain its WAN IPv4 address from a provider DHCP server. The NAT selection ACL decides which inside sources may be translated using the pool. The proposed plan misses the two stated outcomes.
The first step covers (1), but the second addresses verify active bindings assigned by a Cisco IOS DHCP server. The binding table lists leased addresses and client identifiers for the IOS DHCP service. It leaves outcome (2) unfulfilled.
