What is the Ppdioo?
PPDIOO stands for Prepare, Plan, Design, Implement, Operate, and Optimize. PPDIOO is a Cisco methodology that defines the continuous life-cycle of services required for a network.
What is network life cycle?
Network lifecycle phases In its simplest form, network lifecycle management consists of three phases: plan, build and manage. It is also known as design, implement and operate (DIO). The cycle is repeated as the plan phase identifies new requirements. The lifecycle process can also be applied to subtasks.
Which Ppdioo phase develops a network strategy?
The following describes each PPDIOO phase: Prepare phase: The Prepare phase involves establishing the organizational (business) requirements, developing a network strategy, and proposing a high-level conceptual architecture, identifying technologies that can best support the architecture.
What are the main phases of network design per the Pdioo approach often taught by Cisco?
One of the first topic presented in the “Designing for Cisco Internetwork Solutions (DESGN)” book is about the network design methodology. This methodology is composed by six phases closely related: prepare, plan, design, implement, operate, optimize.
What is hierarchical network design?
A hierarchical network design involves dividing the network into discrete layers. Each layer, or tier, in the hierarchy provides specific functions that define its role within the overall network.
What is network design process?
Network design refers to the planning of the implementation of a computer network infrastructure. Network design is generally performed by network designers, engineers, IT administrators and other related staff. It is done before the implementation of a network infrastructure.
What is the goal of network design?
The objective of network design is to satisfy data communication requirements while minimizing expense. Requirement scope can vary widely from one network design project to another based on geographic particularities and the nature of the data requiring transport.
Which are the three Cisco network Architectures for the Enterprise?
The three architectures that were developed by Cisco include the Borderless Networks Architecture, the Data Center and Virtualization Architecture and Collaboration Architecture; this article gives a high level overview of these three architectures.
Which three types of servers are placed in the e commerce submodule choose three?
Web, application, and database servers are placed in the e-commerce submodule.
What are the basic principles of network design?
Good designs should:
- Deliver services requested by users.
- Deliver acceptable throughput and response times.
- Be within budget and maximise cost efficiencies.
- Be reliable.
- Be expandable without major redesign.
- Be manageable by maintenance and support staff.
- Be well documented.
What is the role of network design in a supply chain?
The purpose of supply chain network design is to strengthen your supply chain by not only through mapping and modeling but also ensuring you are optimizing every part of it, at least what you can control. Even those elements seemingly out of your control can be mitigated if they are detected early enough.
What are the 3 layers of the hierarchical design model?
This topic discusses the three functional layers of the hierarchical network model: the access, distribution, and core layers.
What are network design principles?
Network design principles: This section reviews the three pillars needed to design enterprise networks: modularity, hierarchy, and resiliency. The subsequent sections extend these concepts by segmenting the enterprise network into multiple blocks. The subsequent sections go into details of each of these modules. ■
What are Cisco architectures?
Cisco® Digital Network Architecture (Cisco DNA™) is your team’s bridge to an intent- based network. It is an open, extensible, software-driven architecture that accelerates and simplifies your enterprise network operations, while lowering costs and reducing your risk.
Why use the ppdioo model?
Why use the PPDIOO model? Lowering the total cost of network ownership: Companies try to lower the total cost of network ownership while they add new technologies to an existing network, procure equipment, train staff, manage network performance, and maintain the network.
What is Cisco ppdioo?
What is Cisco PPDIOO? PPDIOO (Prepare, Plan, Design, Implement, Operate, and Optimize) is the network life cycle that is defined by Cisco. PPDIOO has the six phases or steps for designing a network and these design phases are as following:
What does ppdioo stand for?
Sample Chapter is provided courtesy of Cisco Press . Date: Jul 15, 2010. This chapter introduces you to the concepts of enterprise campus designs, along with an implementation process that can ensure a successful campus network deployment. PPDIOO stands for Prepare, Plan, Design, Implement, Operate, and Optimize.
What is the design phase in ppdioo?
Since PPDIOO is all about network design, you can imagine the importance of the design phase. Here you need to produce the design document of the network, starting from the specifications. This is the primary goal of network designers.
