質問 # 25
Which three items can be contained in a project? (Choose three.)
正解:A、B、C
解説:
In Tableau Server, projects are containers for organizing and securing content. They help manage permissions and structure content hierarchically. Let's define what can be contained:
* Workbooks: Visualizations and dashboards published to the Server.
* Data Sources: Published connections or extracts reusable across workbooks.
* Nested Projects: Sub-projects within a parent project, introduced in later versions (e.g., 2018.2) for deeper organization.
* Option B (Workbooks): Correct. Workbooks are the primary content type in projects, containing views and dashboards.
* Option C (Nested Projects): Correct. Nested projects allow hierarchical structuring (e.g., a "Sales" project with "Q1" and "Q2" sub-projects), with inherited or custom permissions.
* Option D (Data Sources): Correct. Published data sources reside in projects, providing reusable data connections.
* Option A (Groups): Incorrect. Groups are collections of users managed at the site or server level, not stored within projects. Projects contain content, not user entities.
Why This Matters: Projects are key to content governance-knowing what they hold helps administrators organize and secure assets effectively.

質問 # 26
An administrator needs to restore Tableau Server to a new machine after a hardware failure.
Which two files are required? (Choose two.)
正解:A、B
解説:
A full disaster recovery requires the .tsbak file (containing repository and file store data, created via tsm maintenance backup) and the exported configuration/topology settings file (tsm settings export), which is imported on the new server before restoring the backup. tabcmd and log archives are not part of the restore process.
質問 # 27
What is the minimum required free hard disk space recommended for a Tableau Server installation in production?
正解:C
解説:
Tableau Server has specific hardware requirements for production environments to ensure stability and performance. The minimum recommended free disk space for a production installation is 50 GB.
This accounts for:
The installation itself (approximately 1-2 GB).
Space for log files, temporary files, and extracts managed by the File Store and Data Engine.
Room for backups and operational overhead.
The full minimum hardware recommendations for a single-node production deployment are:
8 CPU cores (2.0 GHz or faster).
32 GB RAM.
50 GB free disk space (on the system drive, typically C: on Windows).
Option B (50 GB): Correct. This matches Tableau's official recommendation for production environments.
質問 # 28
What two events must occur for Tableau Server to recompute queries for a workbook cache after a scheduled refresh? (Choose two.)
正解:A、C
解説:
Tableau Server uses caching to speed up workbook loading by storing query results. After a scheduled extract refresh updates the data, the cache may need recomputing--let's dive into the mechanics:
Caching Basics:
VizQL Cache: Stores rendered views and query results for faster access. Refresh Trigger: A scheduled refresh updates the underlying extract (.hyper), but the cache isn't automatically invalidated--it's demand-driven.
Recompute Conditions: Tableau recomputes the cache when the workbook is accessed (viewed) and its data has changed (e.g., via refresh).
Option B (The workbook has upcoming scheduled refresh tasks): Correct. Why: An upcoming refresh task indicates the workbook relies on an extract with a schedule. After the refresh runs, the data changes, priming the cache for recomputation on next view. Without a schedule, no refresh occurs, so this is a prerequisite. Detail: Schedules are set in Schedules > Tasks--e.g.,
"Daily at 2 AM."
Option D (The workbook has been viewed recently): Correct. Why: Viewing triggers cache recomputation if the data has changed (e.g., post-refresh). Tableau uses a "lazy caching" model-- cache updates only when a user loads the workbook, ensuring fresh results. Detail: "Recently" isn't strictly defined but implies post-refresh access.
質問 # 29
Several Tableau Server users published workbooks that have large extracts. After several weeks of use, the users abandoned the workbooks. What should you do to identify the abandoned workbooks?
正解:C
解説:
Abandoned workbooks-those no longer actively used-can clutter Tableau Server and consume resources (e.
g., disk space for extracts). Identifying them efficiently requires leveraging built-in administrative tools rather than manual or destructive methods. Let's explore this in depth:
* Tableau Server Admin Views: Tableau provides pre-built administrative views to monitor server health, usage, and content. The Stale Content view, accessible under Server > Status > Administrative Views, is specifically designed to identify content (workbooks, data sources) that hasn' t been viewed or modified recently. It shows:
* Content name, owner, and project.
* Last viewed date and last modified date.
* View count over a period.This view uses Repository data to track usage metrics, making it ideal for spotting abandoned workbooks.
* Option A (Use the Stale Content administrative view): Correct. This is the most efficient and non- invasive method. You can filter by last viewed date (e.g., >30 days ago) to identify workbooks with large extracts that users have stopped accessing. From there, you can contact owners or delete the content if policy allows. It's a server administrator's go-to tool for content management.
* Option B (Examine extract files in ProgramData/.../extract): Incorrect and impractical. The ProgramData/Tableau/Tableau Server/data/tabsvc/dataengine/extract directory stores .hyper extract files, but:
* File names are cryptic (e.g., GUIDs), not tied directly to workbook names.
* It doesn't indicate usage or abandonment-only file presence and size.
* Manual inspection is time-consuming and error-prone compared to the Stale Content view.
* Option C (Delete all extracts and allow them to be re-generated): Incorrect and risky. Deleting extracts (e.g., via tsm maintenance cleanup) removes them without identifying usage. Regeneration only occurs if a schedule or user triggers it, potentially disrupting active users and losing historical data unnecessarily.
* Option D (View all workbooks, and sort by the Modified date): Partially effective but inefficient. In the Tableau Server UI (e.g., under Content > Workbooks), you can sort by "Last Modified," but:
* It doesn't show viewership (a workbook might be modified recently but unused).
* It's manual and doesn't scale for large deployments compared to the Stale Content view.
Why This Matters: The Stale Content view leverages Tableau's metadata to provide actionable insights, saving time and reducing risk compared to manual or destructive alternatives. It's part of Tableau's governance toolkit.
