Cisco 200-301 Questions Answers

For voice over WLAN, the WLC QoS profile should be Platinum. Cisco wireless QoS profiles map traffic treatment to application sensitivity: Platinum is intended for voice, Gold for video, Silver for best effort, and Bronze for background traffic. Voice is extremely sensitive to delay, jitter, and packet loss, so it requires the highest WLAN QoS treatment available in the controller GUI. Selecting Silver would treat the WLAN like normal best-effort data, which is unacceptable for real-time voice. Gold is better than best effort, but Cisco positions it for video rather than voice. Bronze deliberately gives low-priority treatment to background traffic. This is an IP Services topic because QoS behavior determines how network devices classify, queue, and prioritize traffic. In a CCNA v1.1 context, do not overthink the wireless GUI wording: when the application is voice, choose the controller profile explicitly designed for voice. That profile is Platinum.

Cisco DNA Center is more extensible than traditional device-by-device campus management because it exposes APIs and integration points. REST APIs allow external applications and automation systems to interact with Cisco DNA Center programmatically instead of relying only on manual GUI or CLI workflows. SDKs extend the platform model by helping integrate third- party network devices and applications where supported. This is fundamentally different from logging into each switch with SSH and pasting commands. Adapters that support every IOS family are not the central extensibility answer, and customized product versions by enterprise size are not what the question asks. Modular design may describe software architecture generally, but the explicit extensibility capabilities tested by Cisco are APIs, adapters, and SDKs. Cisco CCNA v1.1 Automation and Programmability includes controller-based networking, REST APIs, and Cisco DNA Center. The exam logic is direct: extensibility means outside systems can interact with and build on the controller platform. REST APIs and third-party SDK support provide that ability.

Answer A is the technically correct selection. OM3 and OM4 are both multimode fiber types with a 50-micron core. OM4 supports higher bandwidth and longer distances for some speeds, but both share the 50/125-micron multimode physical profile. 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 9-micron core is single-mode fiber, and 62.5-micron describes older multimode categories. 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 design goal is to add coverage cells without creating unnecessary contention. Adjacent Wi-Fi cells should use nonoverlapping channels so clients in neighboring coverage areas do not compete on the same RF channel. In the 2.4-GHz band, that usually means channels 1, 6, and 11 in many regulatory domains. The 5-GHz band provides far more channel capacity than 2.4 GHz and is preferred where client capability and design requirements support it. The source answer that selected same-channel adjacent APs is wrong: placing neighboring APs on the same channel increases co-channel contention, not throughput. A repeater AP is not the standard answer for overlapping channel design, and autonomous AP mode is not required simply to select 5-GHz channels. Cisco CCNA 200-301 v1.1 wireless fundamentals expects candidates to understand channel planning, cell overlap, and RF capacity. The correct recommendations are to use the larger 5-GHz channel set where appropriate and configure overlapping cells on nonoverlapping channels.
