When preparing for the S90.20 SOA Security Lab Exam by Arcitura Education Inc. , one of the most misunderstood topics is the difference between message-level security and transport-level security (HTTPS) . Many candidates assume HTTPS is enough to secure services. The S90.20 lab proves otherwise. This article explains what the exam really evaluates — and why message-level protection is critical in Service-Oriented Architecture (SOA). Understanding Transport-Level Security (HTTPS) HTTPS uses SSL/TLS to encrypt communication between client and server. What HTTPS Protects: Data in transit Communication channel Server identity (via certificate) How It Works: TLS handshake establishes encrypted tunnel Entire message is encrypted during transmission Once received, message is decrypted Limitation in SOA Context: Once the message reaches an intermediary or internal service, the encryption layer ends. In multi-hop SOA environments, this creates security gaps. ...

Modern enterprises are no longer operating from a single data center. Applications are distributed across branch offices, SaaS platforms, and multiple cloud providers. This is where SD-WAN and cloud integration become critical — and why it’s an important topic in the Cisco 500-560 Networking: On-Premise and Cloud Solutions exam . This guide explains the fundamentals you must understand for the exam and real-world deployments. What Is SD-WAN? SD-WAN (Software-Defined Wide Area Network) is a technology that simplifies the management and operation of a WAN by separating the networking hardware from its control mechanism. Instead of relying only on expensive MPLS circuits, SD-WAN: Uses broadband, LTE, and MPLS together Dynamically selects the best path Centralizes policy management Improves application performance Cisco’s primary SD-WAN solution: Cisco SD-WAN Why SD-WAN Matters in Cloud Environments Traditional WAN architectures were designed for traffic flowing...

If you're preparing for the PL-500 Microsoft Power Automate RPA Developer , you must clearly understand the difference between Attended and Unattended RPA . This is one of the most tested topics in the exam. Microsoft evaluates whether you can: Choose the correct automation model Recommend the right license Design cost-effective automation Understand security implications Identify infrastructure requirements Let’s break it down clearly. What Is RPA in Power Automate? In Microsoft Power Automate , RPA (Robotic Process Automation) refers to Desktop Flows that automate: Legacy desktop applications Web apps without APIs Windows UI interactions File system operations On-prem systems RPA uses UI automation rather than APIs. Now let’s compare the two models. What Is Attended RPA? Attended RPA runs with human interaction . It is triggered manually by a user and executes on that user’s machine. Key Characteristics User must be logged in Tr...

Machine learning models are not “set and forget.” Over time, data changes, user behavior shifts, and business rules evolve , causing even the best models to lose accuracy. For the AWS Certified Machine Learning – Specialty (MLS-C01) exam , you’re expected to know when retraining is required and how to automate it safely on Amazon Web Services . This article explains retraining triggers, automation strategies, and exam-ready decision logic . Why Automatic Retraining Matters in MLS-C01 MLS-C01 focuses on production ML systems , not experimental notebooks. AWS tests your ability to: Detect performance degradation Decide when retraining is necessary Automate retraining without disrupting production Validate models before redeployment ❗ Retraining too often wastes money. ❗ Retraining too late breaks business outcomes. The correct answer is balance , driven by monitoring and automation. When Should ML Models Be Retrained? MLS-C01 scenarios usually hint at retraining needs wi...
