What is Cisco Data Center Layer 2/Layer 3 Connectivity?
Starting with the Cisco Data Center Certification, Cisco is a global leader in providing technical solutions in the computer networking field. It offers specialized technical certifications that allow professionals in the network industry to showcase their expertise. These certifications not only help individuals demonstrate their skills but also broaden their career opportunities and enhance their earning potential.
Cisco Data Center Layer 2/Layer 3 Connectivity is a key topic covered in the CCIE Data Center lab examination. Candidates must pass the written examination for the CCIE Data Center without formal prerequisites before taking the lab exam. The lab exam can be taken within 18 months of passing the written exam. Once candidates schedule their lab exam, preparation is critical to success. Without proper planning, candidates risk wasting both exam fees and time. If a candidate fails the lab exam, they must retake it within the next 12 months to maintain the validity of their written exam.
The key to passing the lab exam is hands-on practical knowledge, as candidates must be familiar with the exam's requirements and how to execute them effectively.
CCIE Data Center Lab Exam Structure
The lab exam is an eight-hour test divided into two parts:
-
Diagnostic Module (One Hour Duration)
In this module, candidates are given one hour to diagnose issues in complex data center topologies using available resources, without accessing any devices. -
Configuring and Troubleshooting Module (Seven Hours Duration)
In this module, candidates must demonstrate their ability to configure and troubleshoot data center topologies based on practical experience.
The tip for passing the entire lab exam is to gain solid hands-on practice.
Core Exam Topics for CCIE Data Center Lab Exam
The Cisco Data Center Layer 2/Layer 3 Connectivity topic is a critical area in the CCIE Data Center lab examination. This topic evaluates candidates' ability to design, implement, and troubleshoot layer 2 technologies, including link aggregation, tagging/trunking, and Spanning Tree Protocol. Successful candidates will also be proficient in:
- Designing, implementing, and troubleshooting external fabric connectivity using L2/L3Out and VRF-Lite
- Describing interfabric connectivity through multipod and multisite
- Designing, implementing, and troubleshooting overlays using VXLAN, EVPN, and OTV
- Routing protocols and features such as OSPF, IS-IS, BGP, BFD, and FHRP
- Multicast protocols like PIM, IGMP
- Traffic management such as Queueing, Policing, Classification/Marking, and RoCE
Broader Applicability of Layer 2/Layer 3 Connectivity
Cisco Data Center Layer 2/Layer 3 connectivity has broader applicability, making it an essential area of focus. To excel in this area, candidates should familiarize themselves with the OSI 7-layer model, which is a conceptual framework used to describe the layers of networking systems. A solid understanding of the OSI model will help candidates grasp layer concepts more effectively and improve their hands-on proficiency in the topic.
