Data Engineering on Microsoft Azure Questions and Answers
Question 49
What should you do to improve high availability of the real-time data processing solution?
Options:
A.
Deploy identical Azure Stream Analytics jobs to paired regions in Azure.
B.
Deploy a High Concurrency Databricks cluster.
C.
Deploy an Azure Stream Analytics job and use an Azure Automation runbook to check the status of the job and to start the job if it stops.
D.
Set Data Lake Storage to use geo-redundant storage (GRS).
Answer:
A
Explanation:
Guarantee Stream Analytics job reliability during service updates
Part of being a fully managed service is the capability to introduce new service functionality and improvements at a rapid pace. As a result, Stream Analytics can have a service update deploy on a weekly (or more frequent) basis. No matter how much testing is done there is still a risk that an existing, running job may break due to the introduction of a bug. If you are running mission critical jobs, these risks need to be avoided. You can reduce this risk by following Azure’s paired region model.
Scenario: The application development team will create an Azure event hub to receive real-time sales data, including store number, date, time, product ID, customer loyalty number, price, and discount amount, from the point of sale (POS) system and output the data to data storage in Azure
What should you recommend using to secure sensitive customer contact information?
Options:
A.
data labels
B.
column-level security
C.
row-level security
D.
Transparent Data Encryption (TDE)
Answer:
B
Explanation:
Scenario: All cloud data must be encrypted at rest and in transit.
Always Encrypted is a feature designed to protect sensitive data stored in specific database columns from access (for example, credit card numbers, national identification numbers, or data on a need to know basis). This includes database administrators or other privileged users who are authorized to access the database to perform management tasks, but have no business need to access the particular data in the encrypted columns. The data is always encrypted, which means the encrypted data is decrypted only for processing by client applications with access to the encryption key.
