500-425 Cisco AppDynamics Associate Administrator (CAAA) Questions and Answers

Capacity planning is the process of estimating and allocating the resources needed to meet the current and future demands of an application. For a regionally partitioned application, where different users and organizations are assigned to different databases based on their location, capacity planning requires that the administrator monitors the number of users and orgs mapped to each database and ensures that they do not exceed the available resources.

According to the AppDynamics Analytics - AppDynamics, one way to meet this requirement is to schedule an analytics query to check and report on the result periodically. An analytics query is a SQL-like query that allows you to analyze and visualize the data collected by AppDynamics, such as business transactions, logs, metrics, events, and custom data. You can use analytics queries to create dashboards, widgets, reports, and alerts that provide insights into the performance and behavior of your applications and their components.

To schedule an analytics query to check and report on the number of users and orgs mapped to a database, the administrator can follow these steps:

• Go to Analytics > Search.
• Select the data source that contains the user and org information, such as Business Transactions, Logs, or Custom Data.
• Enter the query that counts the number of users and orgs for each database, such as SELECT database, COUNT(DISTINCT user), COUNT(DISTINCT org) FROM data_source GROUP BY database.
• Click the Save button and enter a name and description for the query.
• Click the Schedule button and select the frequency, time range, and recipients for the query execution and report delivery.
• Click Save.

Therefore, A (Schedule an analytics query to check and report on the result periodically) is the correct answer. References:

When you assign users to a group in AppDynamics, you can manage their permissions and access levels more easily. A group is a collection of users who share the same roles and privileges. A role is a set of permissions that define what actions a user can perform on the Controller UI or the Events Service.

According to the System Configuration Guide for Cisco Unified Communications Manager - User Management, the following statement is true about assigning users to a group:

• When you add a role to a group, every user in the group is assigned that role: This means that the users in the group inherit the permissions of the role that you add to the group. For example, if you add the Administrator role to a group, then all the users in that group can perform administrative tasks on the Controller UI or the Events Service.

The other statements are false because:

• When you assign a user to a group, they can only have the roles assigned to that group: This is not true because a user can belong to multiple groups and have multiple roles. For example, a user can be in both the Administrator and the Operator groups and have the permissions of both roles.
• You can list all users in a group that are logged into AppDynamics: This is not true because there is no such feature in AppDynamics that allows you to see thelogin status of the users in a group. You can only see the list of users and groups in the User Management page of the Controller UI or the Events Service.
• When the user logs in they can log in with the group credentials: This is not true because a user cannot log in with the group credentials. A user can only log in with their own username and password. The group credentials are not used for authentication, but for authorization.

Therefore, D (When you add a role to a group, every user in the group is assigned that role) is the correct answer. References:

To find the information that shows the current application, tier, and node that the agent currently reports to, you can go to View my settings > AppDynamics Agents section in the Controller UI. This section shows you the list of agents that are connected to the Controller, along with their status, version, application, tier, and node names. You can also filter the list by agent type, status, or application1 References: 1: AppDynamics Agents

According to the Transaction Thresholds document1, you can set static thresholds for individual business transactions by selecting Individual Transaction Thresholds from the Business Transaction Configuration window. You can then specify the values for Slow, Very Slow, and Stall thresholds for each business transaction. This way, you can customize the thresholds according to the SLA and the expected performance of the long-running transactions. Setting the default thresholds or adjusting the health rules would affect all the business transactions, not just the long-running ones. Therefore, the correct answer is C. References:

• Transaction Thresholds

A group can contain multiple roles, which means that the users in the group inherit the permissions of all the roles assigned to the group. For example, you can create a group that has both the Administrator and the Analytics Administrator roles, and the users in that group can perform both the administration and the analytics tasks1 References: 1: Roles and Permissions

Two types of information that can be shared without an AppDynamics login are Flow Map and Custom Dashboards. Flow Map is a graphical representation of the application topology, showing the interactions between the tiers, nodes, backends, and remote services. CustomDashboards are user-defined views of the application performance data, metrics, and events. You can share these types of information by generating a shareable link from the Controller UI, which can be accessed by anyone who has the link, without requiring a login12 References: 1: Share a Flow Map 2: Share a Custom Dashboard

One possible reason why the host does not appear in the Tiers and Nodes view and there are no metrics in the Metric Browser is that the license count for that agent type has been exceeded. You can check the license usage and availability by going to Settings > License in the Controller UI. If the license count is exceeded, you can either purchase more licenses or deactivate some agents to free up the license slots12 References: 1: License Rules and Restrictions 2: Manage Licenses

A health rule violation canceled warning event or a health rule violation canceled critical event is generated when the health rule processor can no longer accurately assert that the health rule violation continues to violate or that it has ended1. This can happen when the health rule is edited or disabled, among other reasons1. Adding a new condition to the health rule or disabling the health rule are two actions that would trigger a health rule violation canceled event, as they would change the evaluation criteria or stop the evaluation altogether1. Marking the health rule as canceled or removing the health rule from a policy are not valid actions, as they do not affect the health rule configuration or status

According to the Reports document1, the Report Type field determines what kind of information is captured in the report. There are different report types available, such as Application Health Report, Dashboard Report, Controller Audit Report, and so on. Each report type has different fields in the Report Data tab that can be customized. Therefore, to get the desired information in the report, you need to select the appropriate Report Type from the dropdown menu when creating a scheduled report. References:

To examine the Java App agent logs on a host without login access, you can use the Controller UI to request the agent logs. This feature allows you to download the agent logs from the Controller UI without having to access the host machine. You can specify the log level, the time range, and the file size limit for the logs12 References: 1: Request Agent Logs 2: Java Agent Logging

The Policy Test Bench gives administrators the ability to test and debug policy execution. It allows you to simulate events and see how the policies and actions respond to them. You can also view the policy execution logs and troubleshoot any issues1 References: 1: Policy Test Bench

To alert the operations team that a cloud-based application has provisioned a new instance of a JVM, an administrator should create a policy trigger for Discovery > New Node Discovered. This policy trigger will fire an event when a new node is discovered by the AppDynamics Controller, either by auto-discovery or manual registration. The event will contain information such as the node name, tier name, application name, and agent type. The administrator can then configure an action to send an email, SMS, or custom notification to the operations team with the event details. Alternatively, the administrator can also use the built-in alerting feature of the cloud provider to notify the operations team of the new instance creation.

When creating a Health Rule condition, you can use baselines instead of defining a specific threshold for some metrics. Baselines are the dynamic values that represent the normal or expected behavior of a metric, based on the historical data collected by the AppDynamics Cognition Engine. Using baselines can help you account for the variations and seasonality of your application performance, and avoid false positives or negatives. You can use baselines for metrics that have a non-zero average value and a meaningful deviation, such as the overall average response time of a business transaction or an expression containing multiple metrics. You cannot use baselines for metrics that have a zero average value or a negligible deviation, such as the Business Transaction errors per minute or the calls per millisecond.https://www.appdynamics.com/product/how-it-works/application-performance-baseline

The default length of time events can be viewed with full detail before being purged is 7 days, unless archived. Events are records of significant occurrences in the monitored environment, such as errors, exceptions, policy violations, health rule violations, and more. You can view the events in the Controller UI under Events > All Events. You can also archive the events to retain them for longer periods or export them to external systems1 References: 1: Events

To create a user group in AppDynamics, you need to go to Settings > Administration > Groups. A user group is a collection of users who share the same roles and privileges. You can use user groups to manage user access and permissions more easily. You can add, edit, delete, or duplicate user groups from the Groups tab on the Administration page.

According to the Manage Users and Groups - AppDynamics, the following steps are required to create a user group:

• Click the Add button on the Groups tab.
• Enter a name and description for the group.
• Select one or more roles for the group from the Available Roles list. You can also create a new role by clicking the Add Role button.
• Click Save.

Therefore, D (Settings > Administration > Groups) is the correct answer. References:
