Planning

The CCNP SWITCH exam tests very heavily on the planning and verification requirements within the certification blueprint.  All of the exam topics below fall into the “planning” category.
▪Implement VLAN based solution, given a network design and a set of requirements.
▪ Create a VLAN based implementation plan
▪ Create a VLAN based verification plan
▪ Document results of VLAN implementation and verification
▪ Implement a Security Extension of a Layer 2 solution, given a network design and a set of requirements.
▪ Create a implementation plan for the Securitysolution
▪ Create a verification plan for the Security solution
▪ Document results of Security implementation and verification
▪ Implement Switch based Layer 3 services, given a network design and a set of requirements
▪ Create an implementation plan for the Switch based Layer 3 solution
▪ Create a verification plan for the Switch based Layer 3 solution
▪ Document resultsof Switch based Layer 3 implementation and verification
▪ Implement High Availability, given a network design and a set of requirements
▪ Create a High Availability implementation plan
▪ Create a High Availability verification plan
▪ Document results of High Availability implementation and verification
That is a large portion of the CCNP SWITCH exam blueprint.  It’s tough forCisco to test how to write up an implementation plan within the time frame allowed for the exam, so they test it indirectly.  They may present a complicated business problem with many undefined technical “implementation” components and require you to solve the problem.  In order to do so, you’ll have to be able to come up with an implementation plan on the fly to know which technologies, protocols,interfaces, etc. need to be configured.  Once you configure them, you will also need to come up with a “verification plan” in your head so you can verify that the business need was met (and you get your points for the question).
An example may be a complex problem requiring you to configure new VLANs on a recently added switch (VLAN plan), add LACP trunks (HA plan), change the routing on theexisting multilayer switches to add the new VLAN networks (layer 3 planning).  Load balance the all new connections using HSRP (HA plan) based on business VLAN requirements (VALN plan).
It’s easy to see how quickly a problem like that can cover many of the blueprint planning topics in a single exam question.  Expect to see situational problems like that example.

Implementation Plan ComponentsAlmost every network implementation should consist of several phases (ex. install hardware, push configurations, cut-over to production, etc.).  It is important to remember the following steps for each phase:
1. Description of the step
2. Reference to design documents
3. Detailed implementation guidelines
4. Detailed roll-back guidelines in case of failure
5. Estimated time needed forimplementation

Specific Cisco Design Recommendations

There are some general guidelines Cisco recommends around Layer 2 design.  Cisco recommends the local VLAN approach if possible within the campus environment.  That allows the access layer to focus on port density and VLAN termination.  The distribution layer can then be used for routing and boundary definitions.  The core is then used...
