Question 460
An operations ticket for Greenfield Services has two requirements: (1) let a router obtain its WAN IPv4 address from a provider DHCP server, and (2) relay DHCP client broadcasts from a VLAN to a server in another subnet. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) A DHCP client interface requests leased IP parameters instead of using a fixed static address. (2) DHCP relay forwards qualifying broadcast requests as unicast toward the configured server. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Generate appropriate RSA or supported SSH host keys is for generate credentials used by an IOS SSH server, and Use SNMP polling with permitted MIB object identifiers is for collect network interface counters from switches for operational monitoring. SSH server authentication depends on a usable host key rather than only configuring a VTY password. The proposed plan misses the two stated outcomes.
The first step covers (1), but the second addresses send router logs to a centralized log server. A syslog collector aggregates event messages across devices for correlation and retention. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses explain why ordinary TFTP should not traverse an untrusted network. TFTP's simplicity leaves transfers exposed without a separate secure transport boundary. It leaves outcome (1) unfulfilled.
