?? Scenarios Where Layer 4 Distribution Is Not Recommended VPN Traffic Handling VPN tunnels rely on consistent session ownership. Layer 4 distribution can cause asymmetric routing, where return traffic is processed by a different SGM than the one that initiated the VPN tunnel. This breaks tunnel continuity and may lead to dropped packets or failed negotiations. VoIP and SIP Traffic SIP sessions often involve multiple ports and dynamic media streams. Layer 4 hashing can split related traffic across SGMs, disrupting call setup or media flow. High-Availability Clusters (Non-Maestro) If you're integrating Maestro with legacy HA clusters, Layer 4 distribution may interfere with cluster synchronization and failover logic. Application Load Balancers or Stateful Services Services that maintain state across multiple ports or sessions (e.g., web apps with sticky sessions) may experience inconsistent behavior if traffic is split across SGMs. Multicast or Broadcast Traffic Layer 4 dist

Question 29's answer should be B. The principle of inclusiveness in AI focuses on making AI systems available to a broad range of people and ensuring they serve diverse needs. Active learning helps with this by continuously improving the language model's understanding of user utterances. By enabling this feature on your Language Understanding (LUIS) resource lu1, the bot can suggest new utterances from real-world conversations that it's unsure about. You can then review and incorporate these suggestions, which helps the model learn from a wider variety of speech patterns, accents, and phrasings. This process directly contributes to making the bot more robust and accessible to a more diverse user base.

question 84 : A,B,A ? Summarizing Orders by the CustomerID, OrderID, and OrderDate columns will reduce the model size while still supporting current analysis. Yes ? Summarizing the Orders table by key dimensions (CustomerID, OrderID, OrderDate) and aggregating measures like SalesTotal will reduce row-level granularity and shrink the model size. Since the analysis focuses on total sales, order counts, and customer types, detailed line items (ProductID, UnitPrice, Quantity) are not essential. ? Removing CustomerID column from Orders will reduce model size while still supporting current analysis. No ? CustomerID is required to distinguish new vs repeat customers, which is part of the current analysis. Removing it would break that logic. ? Removing UnitPrice and Discount columns from Orders will reduce model size while still supporting current analysis. Yes ? If the analysis does not require breakdowns by price or discount, these columns can be removed. The SalesTotal column already ref

337 The most relevant reason a Data Protection Officer (DPO) would develop a data inventory is: ? B. To determine the impact in the event of a breach Why? A data inventory (or data mapping) is a core requirement under GDPR and other privacy regulations. Its primary purpose is to: Track what personal data is stored, where it resides, how it flows, and who accesses it. Enable breach impact assessments by identifying: Which datasets were compromised. Whose data was affected (e.g., customers, employees). Legal/regulatory risks (e.g., fines for exposing sensitive data). Why Not the Other Options? A. Manage storage requirements ? Secondary benefit, but not the DPO’s primary concern. C. Extend data retention ? Inventory helps enforce (not extend) retention policies. D. Automate deduplication ? IT efficiency goal, not a DPO’s legal/compliance driver. GDPR Compliance Link Article 30 mandates records of processing activities (data inventories) to demonstrate accountability and assess b
