NEW QUESTION # 45
You need to create a dashboard for a logistics company to track delivery performance. The dashboard should display the following information: (1) Total number of deliveries per day, (2) Percentage of deliveries completed on time, (3) Average delivery time per city, (4) Number of deliveries exceeding the SLA (Service Level Agreement) by more than 1 hour. Which of the following chart combinations would be MOST effective to display this information in a clear and concise manner?
Answer: C
Explanation:
A Time series chart is best for showing trends over time (total deliveries per day). A scorecard provides a concise view of a key metric (percentage of on-time deliveries). A geographical map with color-coded cities effectively visualizes location-based data (average delivery time per city). A table provides detailed information on specific instances (deliveries exceeding SLA). Pie Charts are less ideal for percentage since it can be achieved better using Scorecard, heat grid not the best choice when geo is involved and it is less readable.
NEW QUESTION # 46
You have a CSV file loaded into a Snowflake table named 'raw data'. The file contains customer order data, but some rows have missing values in the 'order date' column. You need to create a new table, 'cleaned data' , that contains only valid records and handles missing 'order date' values by substituting them with the date '1900-01-01'. Which of the following approaches is the MOST efficient and correct way to achieve this using Snowflake features?
Answer: A
Explanation:
Option E is the most efficient and correct. 'COALESCE' efficiently handles NULL replacement, and ensures the replacement value is the correct data type (DATE). It also explicitly selects all other columns. Option A only filters out rows with null order_date. Options B, C and D creates a new column, . It does not also implicitly take all columns, which would make this more appropriate.
NEW QUESTION # 47
When handling Parquet files in Snowflake, what limitations or challenges might arise? (Select all that apply)
Answer: C,D
Explanation:
Challenges include handling large Parquet files and querying nested Parquet structures, which might pose limitations or complexities when working with Parquet files in Snowflake.
NEW QUESTION # 48
What is a benefit of using SQL queries that contain secure views?
Answer: C
Explanation:
Secure Views in Snowflake are specifically designed for data privacy and security, particularly when data is being shared across different business units or external accounts. The primary benefit of a secure view is that it prevents users from seeing the internal definitions (the underlying SQL) and protects against "trial-and- error" data discovery.
In a standard view, a savvy user might be able to deduce information about data they are not authorized to see by observing the query optimizer's behavior or by looking at the query profile. For example, by using specific filters or functions, a user might observe how long a query takes to execute or check the statistics to guess the distribution of values in hidden columns. Secure views prevent this by ensuring that Snowflake does not expose the internal metadata or the specific row/column counts that would allow a user to make observations about the quantity or nature of the underlying data that falls outside their access privileges.
Evaluating the Options:
* Option B and C are incorrect because Snowflake does not merely obfuscate bytes or micro-partitions in a way that suggests a simple "hiding" of metrics; it fundamentally changes the query plan generation to ensure security.
* Option D is a common misconception. In fact, secure views can sometimes be less performant than regular views. This is because the Snowflake optimizer is restricted from using certain optimizations (like predicate pushdown) that might inadvertently reveal data patterns to an unauthorized user.
* Option A is the 100% correct answer. The "secure" nature of the view ensures that the user cannot use statistical side-channels or metadata observations to infer the existence or volume of data they are restricted from seeing.
NEW QUESTION # 49
You are analyzing a query profile and observe a high percentage of time spent in 'Remote Scan'. Which of the following actions would be MOST effective in reducing this bottleneck and improving query performance?
Answer: C
Explanation:
High 'Remote Scan' time indicates that Snowflake is spending a significant portion of its time fetching data from remote storage. Clustering on the table based on the query's filter criteria will help Snowflake quickly identify and retrieve only the relevant data, reducing the amount of data scanned remotely.
