The Cisco 500-701 Video Infrastructure Design (VID) certification focuses on video collaboration infrastructure design and is a key certification for verifying enterprise-level video solution design capabilities.

The 2026 exam continues the core architecture, with cloud-native and hybrid integration, high availability and security, and QoS and bandwidth planning as the three core directions, emphasizing design practices for cloud video and edge deployments.

1. Exam Basic Information

The exam lasts 90 minutes and contains 65-75 questions, primarily multiple choice and scenario-based questions. It mainly assesses the design, deployment, operation, and troubleshooting capabilities of video collaboration systems. The core exam points are divided into five modules by weight, with Advanced Cisco Expressway Features accounting for the highest percentage (45%).

2. Key Points of the Five Core Knowledge Modules

(1) Advanced Cisco Expressway Features (45%)

This is the core focus of the exam, requiring mastery of secure and efficient interconnection design for video network boundaries.

Core Components and Security: Understand the edge gateway role of Expressway and master its security architecture, including TLS encryption, multi-factor authentication, access control lists, and firewall policy integration, focusing on addressing the security challenges of cross-domain video communication.

Zone and Subzone Design: Master the logic of Zone and Subzone division, clarify bandwidth management, call routing policies, and access control in different zones, and understand the QoS priority allocation mechanism for video streams in subzones.

Clustering Deployment: Be familiar with the high availability architecture of Expressway clusters, master the design principles of node redundancy, load balancing, and failover, understand cluster state synchronization and disaster recovery solutions, and ensure the continuity of large-scale video calls.

Call Control and Codecs: Master the characteristics and selection of SX, DX, and MX series codecs, understand Expressway's call routing, media forwarding, and resource scheduling mechanisms, and ensure the connectivity and quality of cross-network video calls.

(2) Advanced Cisco Meeting Server Features (15%)

Focus on the elasticity and scalability design of enterprise-level conferencing platforms.

Deployment Model: Master the applicable scenarios for single-node, multi-node cluster, and distributed deployments; understand horizontal/vertical scaling strategies to meet the capacity requirements of meetings of different sizes.

API and Integration: Be familiar with the Meeting Server's REST API; master automated configuration methods for meeting creation, user management, and meeting recording; support seamless integration with business systems.

Advanced Features: Understand the design principles of features such as multiway, content sharing, and cross-platform interoperability (WebRTC); master media resource optimization strategies in high-concurrency scenarios.

(3) Collaborative Meeting Room Solutions (10%)

Covering both on-premises and hybrid deployment meeting room designs.

On-premises Deployment: Master the deployment architecture of Cisco TelePresence Server and Conductor; understand multipoint meeting resource allocation, call scheduling, and QoS guarantee mechanisms; adapt to high-end meeting room scenarios.

Hybrid Deployment: Be familiar with hybrid integration solutions of CMR Premises and cloud services; master the interoperability configuration between on-premises meeting rooms and Webex cloud meetings to ensure cross-domain video quality and security. Terminal Selection: Match different terminal models to the scenario, and understand encoding/decoding capabilities, bandwidth requirements, and compatibility design.

(4) TelePresence Management Suite (TMS) (10%)

Focus on centralized management and operation of video systems.

Core Functions: Master TMS's device management, meeting scheduling, resource pool management, and log auditing capabilities; understand the configuration and use of the unified operation and maintenance interface.

Permissions and Licenses: Be familiar with TMS's role-based access control (RBAC) division; understand role-based access control (RBAC) design; master license management and capacity planning; and ensure compliance of multi-user concurrent management.

Monitoring and Troubleshooting: Master video system status monitoring and fault location methods; understand log analysis and performance tuning strategies; and ensure stable operation of the video system.

(5) Cisco Cloud Video Solution (20%)

In 2026, focus on strengthening cloud-native design and hybrid integration capabilities.

Webex Cloud Integration: Master the deployment models of cloud services such as Webex Meeting and Webex Training; understand the elastic scaling and global node access mechanism of cloud video. Hybrid Services: Focus on mastering the hybrid connection configuration of local video systems and Webex Cloud, including Expressway-C/E deployment, cloud access control, and security policies, to achieve unified scheduling of local and cloud resources.

API and Automation: Familiar with Webex REST API and bot integration, mastering the design principles of scenarios such as meeting automation and user lifecycle management to improve operational efficiency.

3. Key Design Principles for High-Frequency Focus in 2026

(1) QoS and Bandwidth Planning

Define the QoS priority marking of video streams (DSCP/802.1p), understand the bandwidth requirements for different resolutions and frame rates, and plan capacity based on the differences in H.264/H.265 encoding/decoding efficiency.

Understand the impact of network latency, jitter, and packet loss on video quality, and master the selection scenarios for quality optimization technologies such as Jitter Buffer and Forward Error Correction (FEC).

(2) High Availability and Disaster Recovery Design

Master the redundancy strategies for Expressway clusters and Meeting Server multi-nodes, clarify RTO/RPO indicators, design disaster recovery solutions across data centers, and ensure uninterrupted core video services.

Understand the load balancing design of media resource pools to avoid single points of failure and ensure the stability of large-scale concurrent calls.

(3) Security and Compliance

Focus on the implementation of zero-trust architecture in video systems, including device authentication, encrypted transmission, and least privilege access control, and address the data security and privacy protection needs of cloud video scenarios. Master the configuration of video system log auditing and intrusion detection to meet enterprise compliance requirements.

4. Core Focus of Exam Preparation

Exam preparation should focus on Expressway security and hybrid integration as the core breakthrough point, strengthening practical design capabilities in conjunction with cloud video scenarios. Prioritize mastering the integrated design logic of bandwidth-QoS-high availability, and improve problem-solving skills through scenario-based case studies.

Simultaneously, pay attention to the cloudification trend of Cisco's 2026 Collaboration Certification, strengthen the key points of Webex integration design with local systems, and ensure a deep understanding of cloud-native architecture and automated operation and maintenance.
