A

Port 443

25
Q

What are the three different types of platform logs ?

What layer of Azure are they associated with ? (tenant, subscription, resources…)

A

Resource logs - resource layer

Activity logs - subscription layer

Azure Active Directory logs - tenant layer

26
Q

What are 4 destinations where one can send their logs ?

A

The Azure Portal
Azure Log Analytics
A storage account
An event hub

27
Q

The Azure …………………………. surfaces data at the subscription level and can be useful for understanding actions that occur within your environment against the Resource Manager APIs.

A

Activity Log

28
Q

The query language used by Log Analytics is called……………….

A

Kusto

29
Q

Queries always begin with a……………… –either a table or search-based query

A

scope

30
Q

………………………………. target a single table in a Log Analytics Workspace (or database), while ………………………. target all tables by default.

A

Table-based queries

search-based queries

31
Q

What are the two types of queries Log Analytics ?

A

Table - based queries

Search - based queries

32
Q

………………………… queries can be saved for later and/or marked as favorites so they can be retrieved later using the Query explorer

A

Authored

33
Q

What is the path for accessing Sample Queries and authoring your own queries ?

A

Azure Portal - Azure Monitor - Logs blade

34
Q

What is the path in the Azure Portal to create an Application Insight resource ?

A

Azure Monitor - Insights - Applications (left side pane) - Create Application Insight App

35
Q

Alerts in Azure Monitor are centered on alert rules. Alert Rules contain what 4 components ?

A

■ A target resource (or resource type)
■ Conditional logic for the alert with criteria based on the available signals for the target resource
■ An Action Group, or what should happen when the alert rule condition is met
■ A name and description for the alert rule

36
Q

When creating an alert rule, the target resource defines the scope and signals available for the alert.

A target resource is an Azure resource that generates signals. What are the three types of signals ?

A

■ Metrics
■ Log search queries
■ Activity Logs

37
Q

A(n) …………….. is a collection of actions that should occur in response to an alert being triggered.

A

Action Group

38
Q

Action groups are separate resources and are independent of the alert rule.

What does this mean iif you have a large amount of alert rules ?

A

This means that the same Action Group can be used across multiple alert rules.

39
Q

When configuring an action group, in addition to sending email notifications, what are five other actions that you can automate ?

A 
Runbook (Powershell that runs in Azure Automation Service)
Function Apps
ITSM (ServiceNow for example)
Logic Apps
Webhook
40
Q

True or false : Alerts are managed independently of alert rules and maintain their own state.

A

True

41
Q

What are the three states an alert can have ?

A

■ New. The alert is new and has not been reviewed
■ Acknowledged. The issue that generated the alert is being actioned by an administrator
■ Closed. The issue that generated the alert has been resolved, and the alert has been marked as closed

42
Q

True or false : The state of an alert is updated by the user who is interacting with the alert and is not updated automatically by the Azure platform.
