Review knowledge and build confidence before taking the official Spring Professional Certification Exam!This practice tests-only course contains 128 unique questions from the “Spring MVC and The Web Layer” section of the Spring Professional Certification Exam Study Guide. Questions are divided into 5 practice tests reflecting duration and number of questions on official exam. Each Practice Test contains 50 questions with a 90 minutes time limit and 76% passing score.Please note that those are not official Exam Questions, however they were created with care to make sure to capture all required knowledge from the “Spring MVC and The Web Layer” section.Question database contains 128 unique questions, however some of those might be repeated between different practice tests, with altered and randomized form.

Unlock the secrets of modern software architecture with this comprehensive course designed for developers and architects alike. Whether you’re new to architectural design or looking to refine your skills, this course provides the foundational knowledge and practical insights needed to build robust, scalable systems for today’s ever-evolving tech landscape.We start with an introduction to software architecture fundamentals and progress through widely used patterns, including N-Layer, Onion, Hexagonal, and Clean Architecture. These patterns are explored in depth, helping you understand their structure, purpose, and best use cases.You’ll gain expertise in designing modular monoliths using vertical slices, effectively organizing your application into manageable and autonomous modules. Learn how to integrate these modules seamlessly, leveraging communication techniques and event-driven architecture to ensure responsiveness, scalability, and flexibility in complex systems.The course also dives into asynchronous event processing, a critical component of modern systems. Additionally, you’ll master testing modules at various levels, ensuring your architecture remains reliable, robust, and adaptable under real-world conditions.By the end of this course, you’ll be equipped to design systems that balance scalability, maintainability, performance, and innovation, whether working with monoliths or transitioning to microservices. Also, you'll be equipped with multiple to choose from based on the situation. Join today and take your architectural skills to the next level!

The primary objective of this course is to test the learners on their comprehensive understanding of the mechanisms and constraints governing the performance of an LTE network, covering the entire path from the physical layer resources to specialized voice services.During the course, the learner will be tested on the below topics:The fundamental structure and resource hierarchy of the LTE Air InterfaceThe essential process of network synchronization and RRC connection establishmentThe principles of controlling idle mode UEs and managing paging capacityThe unique capacity constraints and quality challenges posed by Voice over LTE (VoLTE) trafficThe specialized signaling and bearer setup for voice servicesUpon taking all quizzes, you would have successfully tested on the core technical architecture of LTE technology, from the 10 ms LTE frame structure and its division into slots containing 7 symbols, to the crucial process of network synchronization where the PSS and SSS combine to form the Physical Cell ID (PCI). Furthermore, you have been tested on the ability to analyze critical operational procedures, including the functions of the Default Paging Cycle (T) for idle UEs, and the fundamental realization that Voice over LTE (VoLTE) capacity dimensioning is often constrained by CCE consumption on the PDCCH rather than data throughput.

Are you tired of running through endless checklists and still missing critical bugs?Do you feel like your testing sessions are not uncovering enough real issues?This course, “How to Do Exploratory Testing That Doesn’t Suck,” is designed to help you master the art of exploratory software testing. You will learn how to think like a tester, uncover hidden bugs, and add real value to your QA work without relying only on scripted test cases.Exploratory testing is one of the most powerful skills for software testers, QA engineers, and anyone responsible for software quality. It goes beyond following instructions. It is about using creativity, curiosity, and strategy to discover what others miss.By the end of this course, you will:Understand why traditional testing sometimes failsKnow where exploratory testing fits in the QA processLearn what exploratory testing is and what it is notBe able to plan an effective exploratory testing sessionRun an exploratory session with clear goals and focusWrite bug reports that developers will actually read and act onGain techniques for getting your team to take exploratory testing seriouslyWatch a real exploratory session in actionAccess practical templates you can start using immediatelyWhy take this course?Exploratory testing is a must-have skill in modern QA. It is fast, efficient, and trusted by top teams to catch defects before they reach customers. With this course, you will learn not just theory but how to actually do it well.
