What Are the Topics Tested in Cisco ENWLSD 300-425?
If you want to get the Enterprise Wireless Design certification or CCNP Enterprise by passing the ENWLSD 300-425 exam, you should prepare to demonstrate your skills and knowledge related to the following four major topics:
- Wireless Site Survey
- Mobility
- Wireless and Wired Infrastructure
- WLAN High Availability
The first topic covers approximately 25% of the exam's questions. When studying for it, candidates will learn about how to collect design requirements and how to evaluate different constraints. They will develop advanced skills on how to manage client density, AP type, real-time apps, deployment type, and security. Also, this domain covers information on how to describe material attenuation and how to weigh its effects on their wireless designed network. Besides, applicants should be proficient in performing and analyzing Layer 1, pre-deployment, post-deployment, and predictive site survey. Last but not least, another subtopic included in this section handles the proper utilization of the planning and evaluation tools for the most important network metrics. Candidates will discover how to use Spectrum Analyzer, Ekahau, AirMagnet, and Chanalyzer tools.
The second domain has 25% of the syllabus and focuses on mobility concepts. To manage related questions in the test, candidates need to understand how to design a mobility group following the requirements imposed by different mobility roles. Also, this topic takes examinees through various concepts that will allow them to properly optimize client roaming. Another important element included here is mobility tunneling validation for the data and control path.
The third section emphasizes wired and wireless infrastructure. Its total weight in the exam's content is around 30%. It is the most important topic since knowledge in this sphere helps individuals determine which are the most important physical infrastructure requirements for their business environment, handle AP power, cabling, mounting, grounding, and switch port capacity. They will also know more about determining logical infrastructure conditions. During preparation, candidates will discover how to identify the proper WLC/AP licensing requirements based on the current wireless architecture. If you want to get the passing score from the first attempt, you should also get familiar with radio management design and applying proper design management tools for different types of wireless networks. Another sub-topic included here handles wireless bridging and high-density wireless network design.
The final topic makes one proficient in WLAN high availability. They will learn about high availability design for controllers, Stateful Switchover, Network Availability through LAG, as well as priority and redundancy anchor controller. Besides, the candidates will know how to design high availability networks suitable for APS. In this sub-topic, they will handle AP prioritization and fallback concepts.
NEW QUESTION 42
A customer asks an engineer to explain the concept of mobility domains and mobility groups. Which statement does the engineer respond with?
- A. A mobility group does not constrain the distribution of security context of a client and also does not constrain AP fail-over between controllers when the WLC are in the same mobility domain.
- B. WLCs do not need to be in the same mobility domain to communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.
- C. If WLCs are in the same mobility domain, they communicate with each other but, if an anchor WLC is present it must be in the same mobility domain for communication to be possible.
- D. If WLCs are in the same mobility domain, they communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.
