A subset of the monitored devices is due for maintenance. These devices are expected to be shut down and restarted multiple times during maintenance.
Which action should be taken to prevent the devices from triggering alerts during this period without impacting data collection?

  1. Disable all alerts during maintenance.
  2. Make unreachable during maintenance.
  3. Mute the devices during maintenance.
  4. Unmanage devices during maintenance.

Answer(s): C

Explanation:

SolarWinds provides several ways to handle maintenance windows, but they have different impacts on historical data. According to the SolarWinds Platform Administrator Guide, "Unmanaging" a node (Option D) stops all polling entirely, resulting in "gaps" in your historical charts.
To prevent notifications while preserving data collection, the best practice is to Mute the devices during maintenance.
When a device is "Muted" (also known as "Pause Actions"), the platform continues to poll the device and record its status and performance metrics (CPU, Memory, Latency) into the database. However, the alerting engine is instructed to suppress any notification actions (emails, scripts, etc.) for that specific entity. This ensures that you have a full historical record of the device's behavior during the maintenance period—showing exactly when it went down and came back up—without flooding the IT team with unnecessary alerts.



A user account has been granted administrator rights in the web console. By default, which area is disabled for the user (i.e., unable to add, edit, schedule, or delete)?

  1. alerts
  2. dashboards
  3. passwords
  4. reports

Answer(s): C

Explanation:

In the SolarWinds Platform, "Administrator" rights in the Web Console grant extensive control over monitoring configurations, but they are distinct from "System Administrator" or "Security Administrator" roles. According to the SolarWinds Platform User Account Management guide, a Web Console Administrator can manage nodes, create alerts , build reports , and customize dashboards.
However, for security reasons, the ability to manage passwords—specifically the credentials used for polling (SNMP strings, WMI service accounts, or external integration secrets)—is often restricted.
While an admin can assign an existing credential to a node, the ability to add, edit, or view the clear-text/obfuscated passwords within the centralized Credential Library is a separate, higher-level security permission. This prevents a standard Web Administrator from potentially harvesting sensitive service account passwords from the database. This "separation of duties" ensures that while a user can manage the monitoring environment, they cannot necessarily compromise the security of the underlying infrastructure accounts.



An alert is needed when the bandwidth utilization on a specific set of router interfaces exceeds 75%. The alert needs to be limited to specific devices and their interfaces. How is this task accomplished?

  1. Create a critical status-based alert and change the interface utilization status.
  2. Modify the scope on the reset conditions to contain the desired nodes and interfaces.
  3. Modify the scope on the trigger conditions to contain the desired nodes and interfaces.
  4. Use an account limitation to limit the alert to desired devices and interfaces.

Answer(s): C

Explanation:

The alerting engine in the SolarWinds Platform uses a "Scope" and "Condition" logic to determine when an action should fire. According to the SolarWinds Platform Alerting Guide, the "Scope" defines which objects the alert engine should evaluate, while the "Condition" defines what performance metric triggers the alert.
To limit an alert to a specific set of router interfaces, the administrator must modify the scope on the trigger conditions. In the Alert Wizard, under the "Trigger Condition" tab, there is a section titled "I want to alert on..." (Interface) and a secondary section for "The scope of the alert". By adding specific rules to this scope—such as Node Name is Router-A or Interface Alias contains WAN—the alert engine will ignore the thousands of other interfaces in the database and only monitor the 75% utilization threshold on those specific targets. Using account limitations (Option D) is incorrect for this purpose, as account limitations affect what a user sees in the console, not how the backend alerting engine processes data.



Agents have been deployed to a Windows server on a network. The agent is to initiate communication with the application server for all agents.
Which firewall port needs to be opened?

  1. TCP 445
  2. TCP 17777
  3. TCP 17778
  4. TCP 17790

Answer(s): C

Explanation:

SolarWinds agents support two communication modes: "Server-Initiated" (Passive) and "Agent-Initiated" (Active). According to the SolarWinds Platform Agent requirements and port information, the direction of communication determines which firewall ports must be open.
When an agent is configured for Agent-Initiated communication (where the agent on the managed node reaches out to the SolarWinds server), it uses TCP port 17778. This port must be open for inbound traffic on the SolarWinds Main Polling Engine or Additional Polling Engine. This mode is highly beneficial for monitoring servers in DMZs or remote sites where the SolarWinds server cannot initiate a connection through the firewall, but the remote node is allowed to communicate back to the primary management network. Port 17777 (Option B) is used for the legacy Orion Information Service, and 17790 (Option D) is used for specific client-to-server messaging in different contexts, but 17778 is the dedicated, encrypted port for agent-initiated data transmission.



Which two of the following statements describe the AppStack tool in SolarWinds Hybrid Cloud Observability (HCO)? (Choose two.)

  1. automatically gathers information about objects in an environment (including relationships)
  2. displays objects in an environment in a customizable and interactive visual mapping
  3. drag and drop performance metrics, events, and log data from multiple device types to a chart for analysis
  4. visually correlates time series data, both historical and current from multiple products and entity types

Answer(s): A,B

Explanation:

AppStack is a specialized visualization tool designed to show the "stack" of dependencies between different layers of an IT environment. According to the SolarWinds Platform Administrator Guide, AppStack has two defining characteristics:
Automatic Relationship Gathering (A): The tool uses the data already collected by various modules (SAM, VMAN, SRM) to automatically map how applications, database instances, servers, virtual hosts, and storage volumes are linked. This eliminates the need for manual manual line-drawing in most cases.
Customizable Visual Mapping (B): It provides an interactive environment view where users can filter by status, application name, or site to see a visual map of the infrastructure. This allows a user to click on a failing application and see exactly which virtual host or storage array might be causing the failure due to its relationship.
Options C and D describe PerfStack (Performance Analysis), which is the tool used for time-series correlation and dragging metrics onto charts. AppStack focuses on the structure of the environment, whereas PerfStack focuses on the performance data of the entities within that structure.



The built-in custom property, AssetTag, was set to mandatory after device monitoring had been set up.
Which two of the following results can be expected from this action? (Choose two.)

  1. asset tag must be provided after the action for all existing monitored devices
  2. asset tag must be provided for all existing monitored devices when polled
  3. asset tag must be provided for all existing monitored devices when edited
  4. asset tag must be provided immediately for all existing monitored devices

Answer(s): A,C

Explanation:

Custom properties can be configured as "Mandatory" to ensure data integrity across the platform. According to the SolarWinds Platform Administrator Guide, changing a property like AssetTag to mandatory after nodes already exist creates an enforcement requirement.
The system does not retroactively block polling or delete nodes (Option B and D are incorrect), but it enforces the requirement during administrative interaction. Specifically:
Requirement after the action (A): Moving forward, any new node added to the system will require the AssetTag field to be populated before the node can be saved.
Requirement when edited (C): For existing nodes that do not yet have an AssetTag, the platform will permit them to exist and be polled normally. However, the next time an administrator attempts to edit the properties of that node, the Web Console will block the "Save" action until a value is provided for the mandatory AssetTag field. This ensures that as the environment is managed over time, the metadata is gradually backfilled until all mandatory requirements are satisfied.



Which two of the following customizations can be made on a report layout? (Choose two.)

  1. font of the report content
  2. logo on the report
  3. position of page number
  4. width of the report

Answer(s): B,D

Explanation:

The SolarWinds Platform web-based report builder provides specific layout options to ensure reports are professional and readable. According to the SolarWinds Platform Reporting Guide, customization of a report's visual structure is handled through the Layout tab.
Logo on the report (B): Administrators can upload a custom company logo to appear in the header of the report. This ensures that exported PDFs and web views align with corporate branding standards.
Width of the report (D): The layout editor allows users to define the report width, typically choosing between a fixed pixel width (often used to ensure a consistent look on printed paper or PDF) or a percentage-based fluid width that adjusts to the browser window.
While the platform allows for some styling, granular control over the font of the report content (Option A) is generally limited to global CSS or predefined themes rather than individual report layout settings. Similarly, the position of the page number (Option C) is usually a fixed element of the report's footer template and is not a standard customizable field within the primary web-based report layout wizard.



Which out-of-the-box property is associated with a web-based report?

  1. category
  2. creator
  3. format
  4. owner

Answer(s): A

Explanation:

In Hybrid Cloud Observability (HCO), reports are organized using specific metadata to make them searchable and manageable. According to the SolarWinds Platform Administrator Guide, every report created or provided out-of-the-box is associated with a category.
Categories serve as the primary organizational structure in the Report Manager. Examples of standard categories include "Inventory," "Performance," "Historical," or "User Accounts".
When creating a new report, the user is prompted to assign it to one of these categories or create a new one, which then dictates where the report appears in the navigation tree.
While the system may track who created a report, fields like "Owner" (Option D) or "Creator" (Option B) are not standard, visible metadata properties used for the primary sorting and management of web-based reports in the same way the category is. "Format" (Option C) refers to the export type (PDF/Excel) and is a function of how the report is run or scheduled, rather than an inherent property of the report definition itself.
