Book SynopsisThis book is aimed at everyone preparing for the ISTQB® Certified Tester – Foundation Level exam based on the Foundation Level syllabus (version 4.0) published in 2023. It provides candidates with reliable knowledge based on this document and thus distinguishes itself from all the information about ISTQB® syllabi and exams on the Internet, which is often of rather poor quality and may even contain serious errors. The book expands and details many issues that are described in the new 2023 version of the syllabus in a perfunctory or general way only. According to the ISTQB® guidelines for syllabus-based training, an exercise must be provided for each learning objective at the K3 level, and a practical example must be provided for each objective at the K2 or K3 level. In order to satisfy these requirements, the authors prepared numerous exercises and examples for all learning objectives at these levels. In addition, for each learning objective, one or more sample exam questions are presented which are similar to those that the candidate will see in the exam. This makes the book an excellent aid for studying and preparing for the exam and verifying acquired knowledge. Table of ContentsPart I: Certification, Syllabus and Foundation Level Exam.- Foundation Level Certificate.- Foundation Level Syllabus.- Foundation Level Exam.- Part II: The Syllabus Content.- 1.

Book SynopsisThe Art of Network Architecture Business-Driven Design The business-centered, business-driven guide to architecting and evolving networks The Art of Network Architecture is the first book that places business needs and capabilities at the center of the process of architecting and evolving networks. Two leading enterprise network architects help you craft solutions that are fully aligned with business strategy, smoothly accommodate change, and maximize future flexibility. Russ White and Denise Donohue guide network designers in asking and answering the crucial questions that lead to elegant, high-value solutions. Carefully blending business and technical concerns, they show how to optimize all network interactions involving flow, time, and people. The authors review important links between business requirements and network design, helping you capture the information you need to design effectively. They introduce today’s most useful models and frameworks, fully addressing modularity, resilience, security, and management. Next, they drill down into network structure and topology, covering virtualization, overlays, modern routing choices, and highly complex network environments. In the final section, the authors integrate all these ideas to consider four realistic design challenges: user mobility, cloud services, Software Defined Networking (SDN), and today’s radically new data center environments. • Understand how your choices of technologies and design paradigms will impact your business • Customize designs to improve workflows, support BYOD, and ensure business continuity • Use modularity, simplicity, and network management to prepare for rapid change • Build resilience by addressing human factors and redundancy • Design for security, hardening networks without making them brittle • Minimize network management pain, and maximize gain • Compare topologies and their tradeoffs • Consider the implications of network virtualization, and walk through an MPLS-based L3VPN example • Choose routing protocols in the context of business and IT requirements • Maximize mobility via ILNP, LISP, Mobile IP, host routing, MANET, and/or DDNS • Learn about the challenges of removing and changing services hosted in cloud environments • Understand the opportunities and risks presented by SDNs • Effectively design data center control planes and topologiesTable of ContentsIntroduction xx Part I Framing the Problem Chapter 1 Business and Technology 1 Business Drives Technology 2 The Business Environment 2 The Big Picture 3 The Competition 4 The Business Side of the Network 5 Technologies and Applications 5 Network Evaluation 6 The Network’s Customers 6 Internal Users 7 External Users 8 Guest Users 9 Technology Drives Business 9 Part II Business-Driven Design Chapter 2 Designing for Change 11 Organic Growth and Decline 12 Mergers, Acquisitions, and Divestments 14 Centralizing Versus Decentralizing 15 Chapter 3 Improving Business Operations 19 Workflow 19 Matching Data Flow and Network Design 20 Person-to-Person Communication 21 Person-to-Machine Communication 21 Machine-to-Machine Communication 22 Bringing It All Together 23 BYOD 24 BYOD Options 24 BYOD Design Considerations 27 BYOD Policy 28 Business Continuity 29 Business Continuity Versus Disaster Recovery 29 Business Continuity Planning 30 Business Continuity Design Considerations 31 Summary 33 Part III Tools of the Trade Chapter 4 Models 35 The Seven-Layer Model 36 Problems with the Seven-Layer Model 38 The Four-Layer Model 38 Iterative Layering Model 39 Connection-Oriented and Connectionless 41 A Hybrid Model 42 The Control Plane 43 What Am I Trying to Reach?
