Cisco 300-625 DCSAN case studies
Cisco 300-625 DCSAN · Put your knowledge to work in context.
The Cisco 300-625 DCSAN exam is a concentration exam in Cisco's data center certification track, focused on implementing and managing storage area networking in the data center. It is aimed at data center engineers, storage administrators, and network professionals who design, deploy, and operate Fibre Channel and converged storage fabrics, and who want to validate specialist skills beyond general switching knowledge. The published blueprint splits the exam into four equally weighted domains of 25 percent each: implementing and managing Cisco MDS switches; configuring and managing Fibre Channel fabrics; configuring and managing FCoE and NPV/NPIV; and configuring and managing Cisco data center storage networking features. Candidates should expect configuration-level and troubleshooting-level material on NX-OS for MDS, including fabric build-out, zoning, VSANs, and edge designs such as NPV and NPIV. The Cisco 300-625 DCSAN case studies are 5 cases and about 3,344 words.
1Shared Admin Account and VSAN-Scoped RBAC on MDS 9396S
A storage team runs eight Cisco MDS 9396S switches on NX-OS 9.3(8). An audit found that every administrator uses one shared local account with the network-admin role, although two TACACS+ servers (10.10.10.21 and 10.10.10.22) are configured in the running configuration.
