CCNP Data Center study guide

CCNP Data Center · Work through your exam, one topic at a time.

CCNP Data Center is an expert-level Cisco certification track for engineers who build, operate, and troubleshoot data center infrastructure. It suits professionals who already hold a professional-level foundation and now spend their days on fabric and switching, unified computing and hyperconverged platforms, storage networking, automation tooling, and data center security controls. The CCNP Data Center study guide has 5 sections and about 1,461 words.

Network

vPC makes two Nexus switches act as one logical switch. The peer-link is a port channel carrying flooded and unknown-unicast traffic plus control PDUs; the peer-keepalive link is a heartbeat path and never carries data.

Compute

Cisco UCS centralizes management in the Fabric Interconnect (FI) pair. In end-host mode (the default) the FIs do not run STP and behave like hosts toward upstream switches, with uplinks trunking all required VLANs.

Storage Network

FC addressing uses the domain ID, the FCID, and the pWWN/nWWN. Know the port types: F (fabric), FL (fabric loop), E (ISL), TE (trunking E), NP (NPV proxy), TF (trunking F), and SD (span destination).

Automation

NX-OS exposes several automation surfaces: NX-API (JSON or XML over HTTPS 443, in either CLI-style or DME object style), NETCONF/YANG, RESTCONF, and the Guest Shell for on-box Python. DCNM/NDFC provides fabric-wide provisioning and templates; Ansible uses nxos modules over network cli or httpapi; POAP automates initial bring-up through DHCP plus TFTP/HTTP and a script.

Security

TACACS+ (TCP 49) encrypts the entire payload and separates authentication, authorization, and accounting, making it the better fit for per-command device administration; RADIUS (UDP) encrypts only the password. RBAC roles limit what an authenticated user may do - network-admin is all-powerful, so scope custom roles and assign them per user or VDC.
