QUESTION 1

You develop an Azure web app. You monitor performance of the web app by using Application Insights. 

You need to ensure the cost for Application Insights does not exceed a preset budget. 

What should you do? 

A. Implement ingestions sampling using the Application Insights SDK. 

B. Set a daily cap for the Application Insights instance. 

C. Implement ingestion sampling using the Azure portal. 

D. Implement adaptive sampling using the Azure portal. 

E. Implement adaptive sampling using the Application Insights SDK. 

Correct Answer: E 

Sampling is an effective way to reduce charges and stay within your monthly quota. 

You can set sampling manually, either in the portal on the Usage and estimated costs page; or in the ASP.NET SDK in

the .config file; or in the Java SDK in the ApplicationInsights.xml file, to also reduce the network traffic. 

Adaptive sampling is the default for the ASP.NET SDK. Adaptive sampling automatically adjusts to the volume of

telemetry that your app sends. It operates automatically in the SDK in your web app so that telemetry traffic on the

network is 

reduced. 

Incorrect Answers: 

B: You can use the daily volume cap to limit the data collected. 

To change the daily cap, in the Configure section of your Application Insights resource, in the Usage and estimated

costs pane, select Daily Cap.

QUESTION 8
You are creating a hazard notification system that has a single signaling server which triggers audio and visual alarms
to start and stop.
You implement Azure Service Bus to publish alarms. Each alarm controller uses Azure Service Bus to receive alarm
signals as part of a transaction. Alarm events must be recorded for audit purposes. Each transaction record must
include
information about the alarm type that was activated.
You need to implement a reply trail auditing solution.
NOTE: Each correct selection is worth one point.
A. Assign the value of the hazard message MessageId property to the DeliveryCount property.
B. Assign the value of the hazard message SequenceNumber property to the DeliveryCount property.
C. Assign the value of the hazard message MessageId property to the SequenceNumber property.
D. Assign the value of the hazard message MessageId property to the CorrelationId property.
E. Assign the value of the hazard message SessionID property to the SequenceNumber property..
F. Assign the value of the hazard message SessionID property to the ReplyToSessionId property.
Correct Answer: DF
D: CorrelationId: Enables an application to specify a context for the message for the purposes of correlation; for
example, reflecting the MessageId of a message that is being replied to.
F: ReplyToSessionId: This value augments the ReplyTo information and specifies which SessionId should be set for the
reply when sent to the reply entity.
Incorrect Answers:
A, B: DeliveryCount
Number of deliveries that have been attempted for this message. The count is incremented when a message lock
expires, or the message is explicitly abandoned by the receiver. This property is read-only.
C, E: SequenceNumber
The sequence number is a unique 64-bit integer assigned to a message as it is accepted and stored by the broker and
functions as its true identifier. For partitioned entities, the topmost 16 bits reflect the partition identifier. Sequence
numbers
monotonically increase and are gapless. They roll over to 0 when the 48-64 bit range is exhausted. This property is read-
only.

You need to configure retries in the LoadUserDetails function in the Database class without impacting user experience.
What code should you insert on line DB07?
To answer, select the appropriate options in the answer area;
NOTE: Each correct selection is worth one point.
Hot Area:lead4pass az-203 exam question q9

Correct Answer:

lead4pass az-203 exam question q9-1

Box 1: Policy
RetryPolicy retry = Policy
.Handle()
.Retry(3);
The above example will create a retry policy which will retry up to three times if an action fails with an exception handled
by the Policy.
Box 2: WaitAndRetryAsync(3,i => TimeSpan.FromMilliseconds(100* Math.Pow(2,i-1)));
A common retry strategy is exponential backoff: this allows for retries to be made initially quickly, but then at
progressively longer intervals, to avoid hitting a
subsystem with repeated frequent calls if the subsystem may be struggling.
Example:
Policy
.Handle()
.WaitAndRetry(3, retryAttempt =>
TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))
);

FutureOrders: SQLFilter HighPriortyOrders: CorrelationFilter CorrelationID only InternationalOrders: SQLFilter Country
NOT USA requires an SQL Filter HighQuantityOrders: SQLFilter Need to use relational operators so an SQL Filter is
needed. AllOrders: No Filter SQL Filter: SQL Filters – A SqlFilter holds a SQL-like conditional expression that is
evaluated in the broker against the arriving messages\\’ user-defined properties and system properties. All system
properties must be prefixed with sys. in the conditional expression. The SQL-language subset for filter conditions tests
for the existence of properties (EXISTS), as well as for null-values (IS NULL), logical NOT/AND/OR, relational
operators, simple numeric arithmetic, and simple text pattern matching with LIKE. Correlation Filters – A CorrelationFilter
holds a set of conditions that are matched against one or more of an arriving message\\’s user and system properties. A
common use is to match against the CorrelationId property, but the application can also choose to match against
ContentType, Label, MessageId, ReplyTo, ReplyToSessionId, SessionId, To, and any user-defined properties. A match
exists when an arriving message\\’s value for a property is equal to the value specified in the correlation filter. For string
expressions, the comparison is case-sensitive. When specifying multiple match properties, the filter combines them as a
logical AND condition, meaning for the filter to match, all conditions must match. Boolean filters – The TrueFilter and
FalseFilter either cause all arriving messages (true) or none of the arriving messages (false) to be selected for the
subscription. References: https://docs.microsoft.com/en-us/azure/service-bus-messaging/topic-filters
