Selected 200-301 CCNA Questions Answers

Answer D is the technically correct selection. In a lightweight AP deployment, the wireless LAN controller handles WLAN policy and forwards authentication requests to the AAA server. The AP provides radio access, but the WLC controls the client WLAN configuration and authentication path in the controller-based architecture. 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. A RADIUS server validates credentials, while TACACS+ is mainly used for device administration; the AP is not the controlling device in this model. 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.

The configured address 192.168.16.143 with a /28 mask is the broadcast address of its subnet, so the router correctly rejects it with a bad-mask message. A /28 mask creates blocks of 16 addresses. In the 192.168.16.128/28 subnet, the usable host range is 192.168.16.129 through 192.168.16.142, and 192.168.16.143 is the directed broadcast address. A broadcast address cannot be assigned to a router interface because it represents all hosts in that subnet, not one device. The issue is not that the router lacks /28 support, and it is not caused by private addressing. It is also not the network address; the network address would be 192.168.16.128. CCNA 200-301 v1.1 Network Fundamentals requires precise subnet boundary recognition. The verified answer is A because the address shown in the exhibit is the subnet broadcast address.

This item is the same STP concept as the previous one: root port selection begins with the lowest total path cost to the root bridge. A switch evaluates each possible path toward the root and selects the port that gives the lowest cumulative STP cost. If multiple ports tie on cost, the switch then applies the STP tie-breakers in order. It compares the lowest neighbor bridge ID, then the lowest neighbor port ID, and finally the lowest local port ID if needed. The exam often repeats this rule because engineers must troubleshoot blocked links by understanding exactly why a port was selected. Cisco CCNA 200-301 v1.1 Network Access includes spanning-tree operation, root bridge behavior, and root port selection. The first criterion is not local port ID or neighbor information. Those are secondary tie-breakers. The correct first criterion is the lowest path cost to the root bridge.

Answer A is the technically correct selection. HTTP GET corresponds to the read operation in CRUD. A GET request retrieves a representation of a resource without creating, modifying, or deleting that resource. 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. POST, PUT, PATCH, and DELETE map more closely to create, update, replace, or delete operations depending on the API design. 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.
