Cisco 300-820 Domains to Nail
To attain a passing score in the Cisco 300-820 exam, the candidate must ace four exam domains and all the terms included in them. These exam objectives are as follows:
- Technologies of WebEx (25%)
The final sector of 300-820 CLCEI exam consists of the concepts and configuration of the WebEx technologies of Cisco. So, in the first place, the entrant needs to be capable of describing the media flows in addition to signaling in the Cisco WebEx Video Mesh execution. In addition to that, this section includes the configuration of WebEx Hybrid/Connector Services that comprise the calendar services like Office 365, message services such as IM&P prerequisites, user WebEx assignment directory services, and bandwidth, endpoint, and clustering video mesh. Here, the applicant also needs to consider all the deployment requirements of the aforementioned services. Finally, this domain details the concept of Jabber offered by Cisco for Cloud & Hybrid installations.
- Configurations of Initial Expressway (25%)
The second domain for the Cisco 300-820 test deals with Expressway initial arrangements. In particular, it will ask the entrant to configure various settings for the expressway that include DNS, network interfaces, certificates, clustering, QoS, and networking firewall regulations. Furthermore, it also includes the configuration of the core Expressway dial plan components such as transforms, search rules, zones, regular expression, and pipes & links. The candidate should also be capable of configuring the Expressway series with the help of prevention measures of toll fraud without CPL custom scripts. Next, this section of the real exam also deals with configuring B2B solution collaboration components that include Microsoft DNS records, Microsoft CA, traversal zones, neighbor zones, transforms, search rules, and the SIP integration for trunks. At last, such an area discusses how to troubleshoot the B2B solution as well as its elements.
- Key Concepts (25%)
The first portion of the final exam includes the key concepts of the collaboration solutions. This way, the candidate is expected to have a thorough understanding of the NAT concept in regards to Collaboration environments. It is also essential for you to know about STUN, ICE, and TURN as well as their purpose. This domain also expects the entrant to have knowledge about the Expressway for the Media Traversal and protocol networking on it. These protocols include H.323 SIP, IPv6, and IPv4. Furthermore, the applicant should be capable of describing Expressway Licensing and its components such as the Option keys, Release key, and license consumptions. The concept of SIP media for the encryption mode, the core Expressway dial plan, and their components will as well be tested in this section. Finally, such a scope touches on various important settings for Expressway such as DNS, network interfaces, certificates, QoS, clustering, and firewall rules. Overall, within such a topic, you'll get to know more about such concepts like Force encrypted/unencrypted, best effort, pipes, links, zones, and auto.
- Remote Access & Mobile (25%)
This part of the official exam is all about remote access as well as various mobile solutions. It consists of questions regarding the configuration of mobile and remote access solutions or MRA for short. This includes components such as DNS record types, certificates, traversal zones for unified communications & the configuration on Expressway, HTTP allow lists, and the SIP trunk profile for security on the Unified Communications Manager of Cisco. The applicant should also be capable of troubleshooting the MRA solutions along with all its components like Microsoft CA, IM&P, Unity Connection, and Expressways if to mention a few.
