Question 1813:
Correct answer: C

• SAST (Static Analysis Security Testing) identifies security vulnerabilities in source code in the development environment by analyzing the code without executing it. It’s typically integrated into the SDLC (e.g., during coding or CI/CD) to catch issues early.

• DAST (Dynamic Analysis Security Testing) tests a running application from an external perspective to find runtime vulnerabilities, not the source code.
• IAST (Interactive Application Security Testing) instruments the running app to detect issues during execution, blending dynamic and some static insights.
• RASP (Runtime Application Self-Protection) provides protections at runtime inside the application; not a source-code analysis method.

Question 1811:
Correct answer: D
Reason:

• If encryption keys are not centrally managed, the DLP tool cannot reliably decrypt and inspect data across the environment. This creates blind spots, weak access control, and auditing issues, undermining the effectiveness of pre-implementation DLP deployment.

• Monitor mode vs block mode affects enforcement; monitor-only reduces effectiveness but is not as fundamental a risk as broken key management.
• Crawlers to discover sensitive data help inventory and classify data; not a primary risk to DLP functionality.
• Deep packet inspection in transit raises privacy/compliance and performance concerns, but is a known DLP trade-off and manageable with policy controls; key management remains the strongest blocker to effective DLP.

Question 121:

• Correct answer: B — a virtual network for FinServer and another virtual network for all the other servers.

• Why:

• Quick note:

Question 86:

• Correct answer: Vertical scaling

• Why: Vertical scaling (scale up/down) means increasing or decreasing the size of a VM by adding memory or CPUs to the same VM. It updates the capacity of a single instance rather than adding more instances.

• How it compares to other terms:

• Takeaway: Use vertical scaling when you need more compute power in a single VM; use horizontal scaling to handle larger workloads by adding more VMs.

Question 73:
I can’t see the image-based statements in Question 73, so I can’t tell which specific statements are true. But I can explain what this type of question is testing and how to decide Yes/No.
What Question 73 is testing

• Your understanding of the cloud service models and the shared responsibility model: IaaS, PaaS, and SaaS.
• For each statement you must decide if it describes the correct responsibility split between you (the customer) and the cloud provider.

• IaaS: You manage the guest OS, applications, and data. The provider manages virtualization, servers, storage, and networking.
• PaaS: You manage the applications and data. The provider manages the OS, runtime, middleware, and underlying platform.
• SaaS: You primarily manage user data and access; the provider handles the entire application, runtime, OS, and underlying infrastructure.

• If a statement says you’re responsible for patching the operating system, that’s true for IaaS but false for PaaS/SaaS.
• If a statement says the provider handles the hardware and network, that’s true for all three, but more specific responsibilities depend on the model.

Question 25:

• Correct answer: D: a new Cognitive Services resource that uses the S0 pricing tier.

• Why: To enable OCR and text analytics in a Cognitive Search enrichment pipeline, you must attach a Cognitive Services resource to the skillset. For cost efficiency on a large document set, choose the base standard tier (S0) rather than higher tiers or a free tier, which may limit enrichments. The OCR capability comes from the Cognitive Services (Computer Vision/Read) and the S0 tier provides a balance of capability and cost.

Question 20:

• Correct answer: D and E.

• Why: Provisioning a QnA Maker service creates:

• Why not the others:

• Quick note: After provisioning, check RG1 to verify the new App Service and Cognitive Search resources.

what if different between speech recognizer and speach synthesizer

• Speech Recognizer (Speech-to-Text): Converts audio input (live mic or audio file) into text. Output is transcripts with timestamps, confidence scores, and optional punctuation. Use cases: meeting transcripts, voice commands, real-time captions.

• Speech Synthesizer (Text-to-Speech): Converts text (or SSML) into audio output. Output is audio data (wav/mp3 or streaming). Use cases: voice prompts, IVR responses, accessibility narrations. You can choose voices, languages, and adjust prosody (rate, pitch, volume).

• Key differences:

• Quick example: Use Speech Recognizer to transcribe a meeting; use Speech Synthesizer to read a script aloud in a chosen voice.

Question 17:

• Correct answer: A Anomaly Detector.

• Why: Anomaly Detector is designed to identify unusual values in time-series data. Your scenario has 100 machines × 50 sensors, generating minute-by-minute data, totaling 5,000 time-series. Anomaly Detector can process each time-series (or batches of series) to flag deviations that may indicate potential failures, which is exactly what you need for predictive maintenance.

• Why not the others:

• Practical note: with 5,000 time series, you’d typically run anomaly detection per series (potentially in parallel) and aggregate results to identify which machines/sensors warrant attention.

Question 12:

• Correct answers: A, B, F.

• Why:

• Why the other options are incorrect:
