How we research and review these pages
When two protocols are supported by Secure Equipment Access? (Choose two.)
Correct Answer:
B, E
Explanation
Secure Equipment Access provides two main protocols for connecting to network devices remotely. Remote access via Telnet, SSH, VNC, or RDP allows engineers to manage routers and gateways from a distance. Web-based access through HTTP or HTTPS offers another standard method for device management. Serial connections and SNMP are monitoring or legacy access methods, not primary secure access protocols. The IoT Operations Dashboard uses these secure access methods to manage edge devices.
Which hardware capability do industrial Ethernet (IE) switches have that Enterprise switches do not have?
Correct Answer:
B
Explanation
Industrial Ethernet switches are built to withstand harsh manufacturing environments with extreme temperatures, vibration, dust, and corrosive conditions. Enterprise switches are designed for climate-controlled data centers. Industrial ruggedization includes wider operating temperature ranges, shock resistance, and protective enclosures. While industrial switches may offer some advanced features, the key differentiator is their ability to survive tough factory conditions. This hardened design is what makes IE switches suitable for IoT deployments in manufacturing.
How is a customer with four OT devices connected to an industrial router with RS232 connections?
Correct Answer:
D
Explanation
The IR1101 is the industrial router that supports RS232 serial connections. It can be equipped with Serial and Ethernet expansion modules to connect legacy OT devices that use serial protocols. The IR1800, IR1835, and IR1840 are designed for different use cases but lack the specific serial expansion capability needed here. When customers need to bridge older serial devices into modern networks, the IR1101 with appropriate expansion modules is the right choice.
Which industrial router platform has Battery Backup Unit (BBU) module?
Correct Answer:
C
Explanation
The IR8140H is a rugged industrial router that includes a Battery Backup Unit module option. This allows the device to continue operating briefly during power loss, critical for mission-critical IoT applications. Other IR models like the IR1101, IR1800, and IR1835 do not have BBU module support. The BBU capability ensures that edge processing and connectivity remain available during unexpected power interruptions in harsh environments.
How is the Cisco IoT Operations Dashboard deployed?
Correct Answer:
C
Explanation
The Cisco IoT Operations Dashboard is deployed as a SaaS solution hosted in the cloud by Cisco. This cloud-based delivery model means customers don't need to install or maintain dashboard infrastructure themselves. On-premises deployment would require significant IT resources. A hybrid approach wouldn't match the published architecture. The SaaS model provides automatic updates, scalability, and centralized management of IoT devices across distributed locations.
Domain 1: Cisco Industrial Ethernet Switching
30%
Learn the Industrial Switches Portfolio and their capabilities including power supply and management options. This foundation area covers how Cisco's industrial switches support mission-critical IoT deployments in manufacturing and utility environments.
Sample question from this domain above:
Q2
Domain 2: Cisco Industrial Wireless
20%
Understand the capabilities of the IW6300 and IW9167 access points and the Ultra-Reliable Wireless Backhaul Solution. Industrial wireless is essential for mobile device connectivity in environments where wired infrastructure is impractical.
Domain 3: Cisco Industrial Routing
25%
Describe the Industrial Routing and gateway portfolio and explain how routers and gateways function including SDWAN support. Industrial routers handle edge processing and secure connectivity for distributed IoT systems.
Sample questions from this domain above:
Q3Q4
Domain 4: Cisco IoT Operations Dashboard
25%
Explain the functionality and architecture of the IoT Operations Dashboard and how Edge Device Manager deploys and manages routers and gateways. The dashboard centralizes visibility and control across your IoT estate.

FAQ
700-821 Exam FAQ
Common questions about the exam itself
What is the difference between 700-821 and other Cisco IoT exams?
700-821 is part of the Cisco Channel Partner Program and focuses on system engineers who design and implement IoT solutions. It covers the full stack of industrial networking products including switches, wireless, routing, and operations tools. Other IoT exams in the track may target different roles or focus on specific product lines.
Does 700-821 require any prerequisites or prior certification?
The official Cisco page does not list formal prerequisites. However, the exam expects foundational knowledge of networking concepts and hands-on experience with industrial networking environments. Most candidates have background in network engineering or industrial systems before attempting this exam.
How long does it typically take to prepare for 700-821?
Preparation time varies based on your background. Candidates with hands-on experience in industrial networking typically need 4 to 8 weeks of focused study. The official IoT Essentials Technical training course helps structure your preparation around the four main objective areas.
What is the Industrial Ethernet Switching domain about?
This domain covers Cisco's industrial switch portfolio, their capabilities, power supply options, and management features. It accounts for 30 percent of the exam and is critical because reliable switching infrastructure is the foundation of any industrial IoT deployment.
How does the IoT Operations Dashboard differ from the individual product management interfaces?
The Dashboard provides centralized visibility and control across all your industrial IoT devices including switches, wireless access points, and routers. Edge Device Manager within the Dashboard lets you deploy and manage routers and gateways at scale without accessing each device individually.
What do candidates find most challenging about 700-821?
Most candidates struggle with the Industrial Routing domain because it requires understanding both traditional routing concepts and SDWAN architecture in industrial contexts. The domain also tests deeper knowledge of how routers and gateways integrate with the operations dashboard.
Can I take the exam online or do I need to visit a test center?
Cisco does not publish the delivery format on the main exam page. Contact your regional Cisco testing administrator or check with authorized exam delivery partners like Pearson VUE to confirm whether proctored online testing is available in your region.
How long does the 700-821 certification remain valid?
The official Cisco exam page does not specify an expiration date or renewal requirements. Check your certification dashboard after passing or contact Cisco Learning Network for the validity period and any renewal options.
What job roles is 700-821 designed for?
The exam targets system engineers who design, deploy, and manage industrial IoT solutions for manufacturing, utilities, and enterprise environments. Holders typically design network architectures and oversee multi-device IoT implementations.
What should I know about the exam day experience for 700-821?
The exam is 60 minutes long with a combination of question types to test your knowledge across four major domains. Bring identification and arrive early. If you are testing online, ensure your testing environment meets Cisco's technical requirements and your proctor can see your workspace.
