High availability ensures that the network remains functional and operational, even in the event of hardware or software failures. This section is all about creating a network that has redundancy built in at every level to prevent downtime.
Redundancy: You’ll need to design networks with redundant devices, links, and protocols to ensure that if one component fails, the network will continue to function.
Protocols: You will learn about HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol), which are used for network resilience and failover.
Network Recovery: Understand how to design networks that can recover quickly from failures using protocols that support rapid convergence.
Performance and scalability are crucial when designing networks that need to grow over time. This section focuses on ensuring that your network design can handle increasing traffic and provide good performance.
Performance Optimization: Learn strategies for optimizing network performance, such as controlling congestion, managing bandwidth, and reducing latency.
Quality of Service (QoS): Understand how to configure QoS to prioritize traffic and ensure that critical applications get the resources they need.
Scalability: Learn how to design networks that can easily scale as the business grows, including using modular designs and scalable routing protocols.
Designing for Security
Security is a critical aspect of any network. In this section, you will focus on how to design networks that are secure and protect against unauthorized access and cyber threats.
Secure Network Architecture: Learn how to design network security with firewalls, ACLs (Access Control Lists), and segmentation to ensure that sensitive data remains protected.
Authentication and Authorization: You will cover the principles of identity and access management, including 802.1X for port-based authentication.
VPNs and Encryption: Learn how to design secure virtual private networks (VPNs) and apply encryption protocols to protect data in transit.
Wireless networking is an important part of modern enterprise designs. In this section, you’ll learn how to design secure and high-performance wireless networks.
Wireless Standards: Learn about different wireless standards, such as 802.11a/b/g/n/ac/ax, and how to apply them in enterprise environments.
Wireless Security: Design secure wireless networks by applying encryption technologies such as WPA2 and WPA3.
Wi-Fi Design: Learn how to plan and design a wireless network to ensure proper coverage and performance.
Network automation is becoming an essential part of modern network design. This section focuses on how to implement automation to simplify network management and improve efficiency.
Network Automation Tools: You’ll learn how to use Cisco tools like DNA Center to automate network management tasks.
Programmability: Learn how to design networks with programmability in mind, allowing for easier configuration, monitoring, and troubleshooting.
Network services such as DHCP, DNS, NAT, and load balancing are essential to the operation of enterprise networks. In this section, you will learn how to design and implement these services.
Application Performance: Learn how to optimize the network for applications and services by designing for load balancing and high availability.
DNS and DHCP: Understand how to design and configure these critical services.
