Exam DP-700: Baseline Diagnostic Assessment

Source

Diagnostic Purpose

This baseline diagnostic assessment evaluates Panagiotis Koletsos’s initial readiness across the 3 core functional domains of DP-700, taking into account his strong architecture, cloud, and relational foundations, and isolating specific high-impact Fabric gaps.

Detailed Domain Analysis & Identified Gaps

1. Strengths (Accelerators)

  • Enterprise Architecture & Medallion Design: Mastered Bronze $\rightarrow$ Silver $\rightarrow$ Gold patterns, Star Schema modeling, and cross-workspace topologies.
  • Relational SQL & Cloud Foundations: Strong comprehension of T-SQL, ACID transaction isolation, and security controls (RLS/CLS).
  • Core Spark Fundamentals: Existing badge in Use Apache Spark in Microsoft Fabric provides strong DataFrame transformation familiarity.

2. High-Impact Target Gaps for Sprint

  1. Fabric Capacity Metrics App & Throttling Mechanics:
    • Precise differentiation between 5-minute interactive smoothing vs 24-hour background smoothing.
    • Throttling debt stages: Interactive Delay (10 min debt) $\rightarrow$ Interactive Rejection (60 min debt) $\rightarrow$ Background Rejection (24 hr debt).
  2. Real-Time Intelligence & KQL Engine:
    • Authoring .alter table policy update functions for transactional stream ETL.
    • Materialized views and time-series anomaly detection functions (make-series, series_decompose_anomalies).
  3. Data Factory & Apache Airflow in Fabric:
    • Handling nested loops via Execute Pipeline activity.
    • Python DAG authoring with FabricRunItemOperator.
