最新的 Salesforce Administrator Analytics-Admn-201 免費考試真題 (Q15-Q20):

問題 #15
You have a server that contains 16 processor cores. What is the default number of VizQL instances configured by the installer?

答案：A

解題說明：
The VizQL Server process in Tableau Server handles rendering visualizations and processing queries for users viewing dashboards or workbooks. During installation, Tableau Server automatically configures the number of VizQL instances based on the number of processor cores on the machine, following this rule:
Default VizQL instances = 2 per node, unless manually adjusted post-installation.
In multi-node setups, additional instances may be added based on core count, but the question specifies a single server with 16 cores.
The installer does not scale VizQL instances linearly with core count by default (e.g., it doesn't set 1 instance per 4 cores). Instead:
For a single-node installation, the default is 2 VizQL instances, regardless of core count (assuming the minimum hardware requirements are met: 8 cores, 32 GB RAM).
Administrators can later adjust this using TSM (e.g., tsm topology set-process) based on performance needs, but the question asks for the default configured by the installer.
Option A (4): Incorrect. Four instances might be configured manually for a 16-core server, but it's not the default.
Option B (6): Incorrect. Six instances exceed the default for a single node.
Option C (10): Incorrect. Ten instances are far beyond the default and would require manual configuration.
Option D (2): Correct. The installer sets 2 VizQL instances by default on a single-node installation.

/en-us/processes.htm).


問題 #16
A user receives an error after attempting to run an extract refresh on the Tableau Server. What should you review to identify the cause of the problem?

答案：B

解題說明：
When an extract refresh fails on Tableau Server, troubleshooting requires identifying the root cause-e.g., connectivity issues, resource constraints, or configuration errors. The Backgrounder process handles extract refreshes, so it's a key focus, but the best diagnostic tool depends on granularity and context. Let's explore this thoroughly:
* Extract Refresh Process:
* An extract refresh pulls data from a source (e.g., database, file) into a .hyper file stored on Tableau Server.
* The Backgrounder executes these tasks based on schedules or manual triggers.
* Errors could stem from: database connectivity, credentials, file access, resource overload, or task misconfiguration.
* Option B (Background Tasks for Extracts administrative view): Correct. This is the most direct and detailed method:
* Location: In the Tableau Server web UI, go to Server > Status > Background Tasks for Extracts (or site-specific under Site > Status).
* Details Provided:
* Task name, schedule, and workbook/data source.
* Start/end times and status (e.g., Failed, Success).
* Error messages (e.g., "Cannot connect to database," "Permission denied").
* Why It's Best: It pinpoints the exact failure (e.g., "timeout," "invalid credentials") for the specific refresh, offering actionable insights without needing to dig through logs manually. Server or site administrators can access this view to diagnose issues quickly.
* Example: If the error is "Database login failed," you'd check credentials in the data source settings next.
* Option A (Status of the Backgrounder process via tsm status -v): Partially useful but insufficient:
* What It Shows: Running/stopped status of all processes (e.g., "Backgrounder: RUNNING").
* Limitation: It confirms if Backgrounder is operational but doesn't reveal why a specific task failed-no error details or task-level granularity.
* Use Case: If Backgrounder is stopped or crashed, this might indicate a broader issue, but the question implies a single refresh error, not a server-wide failure.
* Option C (The UNC path to the extract's data source): Relevant but secondary:
* Context: If the data source is a file (e.g., CSV on a network share), the UNC path (e.g.,
servershare ile.csv) must be accessible.
* Why Not First: The error could be unrelated (e.g., database issue, not file-based). The admin view (B) would reveal if it's a path issue first, guiding you to check the UNC path only if indicated (e.g., "File not found").
* Practical Note: Backgrounder needs share permissions and the Run As account must access it- checking this without context wastes time.
* Option D (Whether project permissions are set to Locked): Unlikely cause:
* Permissions Impact: Locked permissions restrict who can edit/view content, not whether an extract refresh runs-that's tied to the data source's connection settings and Backgrounder execution.
* Exception: If the refresh user lacks "Connect" permission to the data source, it might fail, but this is rare (owner/schedule typically has access). The admin view would flag this.
Why This Matters: The Background Tasks view is Tableau's purpose-built tool for extract diagnostics, saving time and reducing guesswork in production environments.
Reference: Tableau Server Documentation - "Administrative Views: Background Tasks for Extracts" (https://help.tableau.com/current/server/en-us/adminview_background_tasks.htm).


問題 #17
What is the maximum number of tasks that a single Backgrounder process can execute simultaneously?

答案：D

解題說明：
The Backgrounder process in Tableau Server handles tasks like extract refreshes and subscriptions-let's explore its concurrency:
* Backgrounder Behavior:
* Each instance is single-threaded for task execution-one task at a time per Backgrounder.
* Multiple Backgrounders (e.g., in multi-node setups) increase parallelism, but a single Backgrounder is limited to 1 concurrent task.
* Queue: Additional tasks wait in the queue, prioritized by their priority (1-100).
* Option A (One): Correct.
* Details: A single Backgrounder executes one task (e.g., an extract refresh) until completion before starting the next.
* Config: Add more Backgrounders via TSM (tsm topology set-process -n node1 -pr backgrounder
-c 2) for more concurrency.
* Option B (Two): Incorrect.
* Why: Not natively supported-a single Backgrounder doesn't multi-thread tasks.
* Option C (Three): Incorrect.
* Why: Exceeds the single-threaded design.
* Option D (Unlimited): Incorrect.
* Why: Concurrency is fixed at 1 per instance-resources affect queue processing speed, not simultaneous tasks.
Why This Matters: Understanding Backgrounder limits guides scaling-more instances mean more parallel tasks, critical for heavy workloads.
Reference: Tableau Server Documentation - "Backgrounder Process" (https://help.tableau.com/current/server
/en-us/processes.htm#backgrounder).


問題 #18
Which Tableau Server process performs the role of a database for metadata?

答案：D

解題說明：
Tableau Server relies on several processes to function, each with a specific role. The Repository process (powered by PostgreSQL) serves as the database for metadata, storing critical information such as:
* User and group details.
* Permissions and site configurations.
* Workbook and data source metadata (e.g., schedules, subscriptions).
* Option B (Repository): Correct. The Repository is the centralized database that holds all metadata, making it the backbone of Tableau Server's content management. There are typically two instances in an HA setup (one active, one passive), monitored by the Cluster Controller.
* Option A (Data Engine): Incorrect. The Data Engine manages in-memory data processing and extract storage (e.g., .hyper files), not metadata. It's separate from the Repository.
* Option C (Backgrounder): Incorrect. The Backgrounder handles background tasks like extract refreshes and subscriptions, but it doesn't store metadata-it interacts with the Repository to retrieve task details.
* Option D (File Store): Incorrect. The File Store manages physical extract files and workbook assets, not metadata, which is stored in the Repository.
Reference: Tableau Server Documentation - "Tableau Server Processes" (https://help.tableau.com/current
/server/en-us/processes.htm).


問題 #19
What account should you use to run the Tableau Server installation program?

答案：D

解題說明：
Installing Tableau Server on Windows requires an account with sufficient privileges to configure services, write to the file system, and manage registry settings. Let's analyze this in depth:
* Installation Requirements:
* The installer creates services (e.g., Tableau Server Gateway), writes to Program Files and ProgramData, and configures TSM.
* It needs local administrative privileges on the machine to perform these tasks.
* Post-install, a "Run As" account can be set for services (e.g., NT
AUTHORITYNetworkService), but this is separate from the install account.
* Option C (An account in the local administrator group): Correct.
* Why: The account must be in the local Administrators group to:
* Install software (UAC elevation).
* Configure services and ports.
* Write to protected directories (e.g., C:Program FilesTableau).
* Examples: A local admin (e.g., Administrator) or a domain user added to the Administrators group (e.g., DOMAINAdminUser).
* Process: Log in as this account, run the installer, and provide TSM admin credentials during setup.
* Option A (A local user account): Incorrect.
* A standard local user (not in Administrators) lacks permissions-installation would fail with
"Access Denied" errors.
* Option B (A domain user account): Incorrect unless clarified.
* A domain user without local admin rights can't install. If it's in the Administrators group, it qualifies, but C is more specific.
* Option D (NT AUTHORITYNetworkService): Incorrect.
* This is a built-in service account for running services (default "Run As" post-install), not for executing the installer-an interactive user account is required.
Why This Matters: Using the right account prevents install failures and ensures secure configuration- critical for production setups.
