Cisco CCNA 200-301 New Questions

Use the displayed drag-and-drop mapping for this item. 802.11 standards differ by frequency band, maximum theoretical rate, modulation, and channel width. The mapping should separate legacy 802.11b/g 2.4-GHz behaviour, 802.11a 5-GHz behaviour, and newer high-throughput standards such as 802.11n/ac. In Cisco CCNA 200-301 v1.1, Network Fundamentals questions frequently test the practical boundary between similar features: what the feature does, where it is configured, and what problem it is meant to solve. Confusing band support with throughput is the usual trap in this question type. A clean way to validate the answer is to map the wording of the scenario to the actual device function. If the feature supplies addressing, forwarding, authentication, trunking, route selection, or controller communication, the answer must match that function exactly rather than a nearby protocol name.

Answer B is the technically correct selection. NETCONF filtering is done by creating an XML filter and passing it to the get_config operation. NETCONF uses XML-encoded RPC messages, so an XML subtree or XPath-style filter reduces the returned configuration to the requested interface section. 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. Parsing with JSON or sending a JSON filter does not match NETCONF data encoding; parsing after retrieval does not reduce server response size. 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.

A frame that fails the Ethernet Frame Check Sequence is counted as a CRC error and also contributes to input errors. The FCS field is the Ethernet trailer’s error-detection value; the receiver recalculates the value and compares it with the frame’s received FCS. If the values do not match, the frame is considered corrupted and is discarded. Cisco interface counters commonly report that condition under CRC, while the broader input errors counter includes CRC and other receive-side problems such as runts, giants, frame errors, overrun, ignored, and no-buffer conditions. Runts and giants are size-related counters, not the direct result of the FCS failure described in the question. The frame counter is not the best paired answer here. In CCNA 200-301 v1.1 Network Fundamentals, this maps to Ethernet operation and interface troubleshooting. The verified answers are D and E: CRC and input errors.

The task describes a default route. A router uses a default route when no more specific route matches the destination address in the routing table. In IPv4, the static default route is written with destination 0.0.0.0 and mask 0.0.0.0, followed by the next-hop IP address or exit interface. Since the router must forward unmatched traffic to 192.168.1.1, the correct configuration is the option that uses ip route 0.0.0.0 0.0.0.0 192.168.1.1. Cisco CCNA 200-301 v1.1 IP Connectivity requires engineers to recognize default routes because they are common at branch routers, internet edges, and lab topologies. A route to a specific network would not satisfy the requirement to forward all unmatched traffic. A default gateway command is for switches or hosts in limited contexts, not the proper router forwarding-table method here. The answer is C because it represents the static default route toward 192.168.1.1.
