Cisco Updated 200-301 Exam Questions and Answers by kamil

The verified answer is C and D. RSTP uses discarding, learning, and forwarding port states. Compared with classic STP, RSTP removes the separate listening and blocking names and converges more quickly through proposal and agreement behaviour. Cisco CCNA 200-301 v1.1 places this skill in Network Access, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. Listening and blocking are associated with 802.1D terminology, and speaking is not an RSTP port state. In production, this distinction matters because a misapplied command or design choice usually creates an outage, a security gap, or unnecessary troubleshooting noise. The correct choice matches the control-plane, data-plane, wireless, security, or services behaviour described in the scenario and should be preferred over options that merely sound related.

To make a switch always win the STP root election for VLAN 750, configure the lowest possible bridge priority for that VLAN. Cisco STP priorities are configured in increments of 4096, and priority 0 is the lowest configurable value. The command spanning-tree vlan 750 root primary is convenient, but it calculates a priority intended to beat the current root at the time the command is entered. It is not as absolute as setting priority 0. Several listed numeric values are invalid or too high to guarantee root status. Cisco CCNA 200-301 v1.1 Network Access tests this because root bridge placement is a core switching design control. A switch becomes root by having the lowest bridge ID, and priority is compared before MAC address. Setting the VLAN priority to 0 gives the switch the strongest possible election position for VLAN 750. The command that best guarantees root status is spanning-tree vlan 750 priority 0.

DHCP dynamically leases IP configuration to clients, and the server can exclude specific addresses from the assignable pool. Exclusions are important because some addresses in the subnet may be reserved for routers, servers, printers, infrastructure interfaces, or static assignments. DHCP leasing means the client receives an address for a defined lease time and must renew it before expiration. Cisco CCNA 200-301 v1.1 IP Services includes DHCP because engineers must understand address pools, default-router options, DNS options, exclusions, and relay behavior. The server, not the client, maintains the pool of assignable addresses. DHCP does not assign addresses forever without renewal. A client can receive DNS server information, but the statement that it can request up to four DNS servers is not the core tested role here. The two correct operational roles are that the DHCP server can exclude addresses from a pool and lease client IP addresses dynamically. Those are A and D.

Answer the displayed drag-and-drop mapping is the technically correct selection. DHCP snooping builds a trusted binding table from legitimate DHCP exchanges. Trusted ports face valid DHCP servers, untrusted ports face clients, and the binding database becomes the source of truth for features such as Dynamic ARP Inspection and IP Source Guard. This aligns with Cisco CCNA 200-301 v1.1 because the exam blueprint requires engineers to recognize operational behaviour from configuration symptoms and topology requirements. Ordinary MAC learning does not validate DHCP messages, and trunking or STP alone cannot prevent a rogue DHCP server from handing out false gateways. Treat the distractors carefully: most are real Cisco terms, but they solve a different problem or operate at a different layer. The selected answer is the one that would be used by an engineer on the device or in the design to produce the outcome stated in the question.
