1.2 Risk and Impact Analysis

1.2.a Take the requirements and perform a risk assessment and impact analysis to narrow down the possible design choices

1.3 Ongoing communications to finalize the business requirements

1.3.a Identify the design choice that meets the business, risk, and customer requirements

2.0 Translating Business Requirements Into Technical Requirements 19%

2.1 Mapping of business requirements

2.1.a Map existing applications to Cisco ACI constructs
2.1.b Map existing network services to Cisco ACI Fabric
2.1.c Create application network profiles that map to the business requirements

2.3.a Analyze the current infrastructure inventory and capacity to meet the requirements
2.3.b Assess the delta between the requirements and the current infrastructure to implement the application

2.4 Translating service level agreements (SLAs) and operational level agreements (OLAs) into technical requirements

2.4.a Plan or design to account for business interruption of various lengths or scopes

3.0 Positioning Application Centric Infrastructure Value Proposition 29%

3.1 Policy based infrastructure management

3.1.a Identify opportunities to automate tasks that are manual today
3.1.b Identify architectural bottlenecks in the current infrastructure that are roadblocks in introducing programmability and automation
3.1.c Is there uniformity in policy across the entire infrastructure or are there policy silos and policy gaps?
3.1.d Describe programming model and APIs available to automate network functions required to deploy applications

3.2 Enhance visibility and control

3.2.a Identify lack of comprehensive visibility and control over resource allocation for applications today and highlight how Cisco ACI can address this limitation
3.2.b Identify number of points of management to see if Cisco ACI can reduce the number to dramatically bring in value addition
3.2.c Identify application performance features that increase scalability or provide optimal traffic steering
3.2.d Describe available tools to provide comprehensive application-level visibility

3.3 Security and compliance

3.3.a Identify any compliance and auditing requirements and highlight key security features of Cisco Application Centric Infrastructure (policy-based forwarding, auditing, forensics across physical and virtual devices)

4.0 Define High-Level System Architecture 28%

4.1 Software architecture and design

4.1.a Take a set of software requirements or details about a solution and generate (identify, pick, choose) a design document (class hierarchy, object model, Entity Relationship (ER) diagram)

4.2 Infrastructure architecture and design (physical and virtual)

4.2.a Take a set of infrastructure requirements or details about a solution and generate (identify, pick, choose) a design document (configuration or design change)

4.3 Identify different integration/interoperability points between different systems

4.3.a Understand the differences (compare and contrast) between different integration interfaces (knows what to use when and why)
