Databricks Databricks-Certified-Data-Engineer-Professional日本語 Exam FAQ — What Candidates Ask Most

The Databricks-Certified-Data-Engineer-Professional日本語 exam is the official Databricks exam for Databricks Certified Data Engineer Professional Exam (Databricks-Certified-Data-Engineer-Professional日本語版). Passing it earns you the Databricks Certified Data Engineer Professional credential, which sits at the Professional level. It is also connected to Databricks Certified Data Engineer Associate, so what you learn carries over if you plan to pursue those paths as well. Employers treat the certification as verified proof of skill, which is why structured preparation with 2Pass4sure's practice questions pays off.

The Databricks-Certified-Data-Engineer-Professional日本語 exam contains 45-60 questions, and the time limit is 120 minutes. Translate that into a pacing plan before exam day: know roughly how long you can afford per item, flag anything that stalls you, and circle back at the end instead of burning minutes. Two or three full timed sessions in 2Pass4sure's test engine will teach you that rhythm far better than untimed reading ever will.

The passing score for the Databricks-Certified-Data-Engineer-Professional日本語 exam is 70%, and the official registration fee is $200 USD. Remember that a failed attempt means paying that fee again in full for a retake, so treat self-assessment as part of the budget: run 2Pass4sure's practice questions under timed conditions and only book your seat once your scores sit comfortably above the passing bar.

Databricks Certified Data Engineer Professional Exam (Databricks-Certified-Data-Engineer-Professional日本語版) Sample Questions:

Question 1

夜間バッチジョブは、クラウドオブジェクトストレージコンテナからすべてのデータファイルを取り込むように設定されています。このコンテナには、YYYY/MM/DDというネストされたディレクトリ構造でレコードが保存されています。各日付のデータは、その日にソースシステムによって処理されたすべてのレコードを表します。一部のレコードはモデレーターの承認待ちのため、処理が遅れる場合があります。各エントリは製品に対するユーザーレビューを表し、以下のスキーマを持ちます。
user_id STRING、review_id BIGINT、product_id BIGINT、review_timestamp TIMESTAMP、review_text STRING 取り込みジョブは、ソースシステムと同一のスキーマを持つターゲットテーブル reviews_raw に、前日のすべてのデータを追加するように設定されています。パイプラインの次のステップは、reviews_raw に挿入されたすべての新規レコードを、データが完全に重複排除、検証、およびエンリッチされたテーブルに伝播するバッチ書き込みです。
このデータバッチを伝播するための計算コストを最小限に抑えるソリューションはどれですか?

A. reviews_raw テーブルでバッチ読み取りを実行し、自然な複合キー user_id、review_id、product_id、review_timestamp を使用して挿入のみのマージを実行します。
B. トリガー ワンス実行モードを使用して reviews_raw テーブルに対して構造化ストリーミング読み取りを構成し、新しいレコードをバッチ ジョブとして処理します。
C. reviews_raw 内のすべてのレコードを再処理し、パイプラインの次のテーブルを上書きします。
D. Delta Lake のバージョン履歴を使用して、reviews_raw の最新バージョンと 1 つ前のバージョンの違いを取得し、これらのレコードを次のテーブルに書き込みます。
E. review_timestamp に基づいて reviews_raw テーブル内のすべてのレコードをフィルタリングし、過去 48 時間以内に生成されたレコードを一括追加します。


Question 2

Spark ドライバーの log4j 出力を解析するときに、テキストの重要な領域を識別するために使用できるテクノロジは次のどれですか。

A. C++
B. Julia
C. Scala Datasets
D. Regex
E. pyspsark.ml.feature


Question 3

daily_store_sales テーブルには、store_sales_summary を更新するために必要なすべての情報が含まれています。
このテーブルのスキーマは次のとおりです。
店舗ID INT、売上日 DATE、売上合計 FLOAT
daily_store_sales がタイプ 1 テーブルとして実装され、手動データ監査後に total_sales 列が調整される可能性がある場合、store_sales_summary テーブルで正確なレポートを生成するための最も安全な方法はどれですか。

A. daily_store_sales テーブルに対する構造化ストリーミング読み取りとして適切な集計ロジックを実装し、upsert ロジックを使用して store_sales_summary テーブルの結果を更新します。
B. daily_store_sales テーブルに対して適切な集計ロジックをバッチ読み取りとして実装し、store_sales_summary テーブルに毎晩新しい行を追加します。
C. daily_store_sales テーブルに対するバッチ読み取りとして適切な集計ロジックを実装し、upsert ロジックを使用して store_sales_summary テーブルの結果を更新します。
D. daily_store_sales テーブルに対してバッチ読み取りとして適切な集計ロジックを実装し、各更新で store_sales_summary テーブルを上書きします。
E. Structured Streaming を使用して、daily_store_sales の変更データ フィードにサブスクライブし、更新ごとに store_sales_summary テーブルの集計に変更を適用します。
