Cisco 300-425 Exam Overview:

Highlights of Exam Topics

Cisco 300-425 evaluates the candidates’ knowledge of various topic areas or knowledge domains. The skills measured in this exam are combined in the following objectives:

• Wireless Site Survey (25%)

  Within this section, the students need to demonstrate how good they can collect design requirements and also evaluate constraints. It means that they have to be conversant with determining client density, AP type, real-time applications, deployment type, and security. The topic also covers the learners’ expertise in describing material attenuation and its impact on wireless design, performing a predictive site survey, a pre- and post-deployment site survey, as well as utilizing planning tools and evaluating key network metrics (Spectrum Analyzer, PI, Chanalyzer, AirMagnet, and Ekahau).

• Wired and Wireless Infrastructure (30%)

  In the framework of this objective, the test takers should demonstrate their knowledge and ability to determine physical infrastructure requirements, such as grounding, mounting, switch port, capacity, cabling, and AP power. They also need to know how to determine logical infrastructure requirements, for example, AP/WLC licensing requirements according to the type of wireless architecture. The topic also covers their expertise in designing radio management, high-density wireless networks, and applying design requirements for various types of wireless networks, such as data, voice and video, hyperlocation, and location. The applicants also need to show their capability of designing wireless bridging (mesh). This includes roaming, modes of operation, WGB, and Ethernet bridging.

• Mobility (25%)

  This area evaluates the individuals’ skills in designing mobility groups according to the roles and validating tunneling for control path and data. It also measures their competency in optimizing client roaming.

• WLAN High Availability (20%)

  This domain includes designing high availability for controllers. The questions under this knowledge area are designed to test the candidates’ knowledge of stateful switchover (SSO) and ensure network availability through LAG. The examinees should also have knowledge of priority and redundancy of the anchor controller. Moreover, within the framework of this subject, they need to demonstrate their competency in designing high availability for APs. This includes fall-back (assigning tertiary, secondary, and primary) and AP prioritization.
