Azure Subscriptions - Correct Answer Provides you with authenticated and authorized access to Azure
products and services and allows you to provision resources on Azure. It is a logical unit of Azure services
that links to an Azure account.
Note:
- Can contain multiple account administrators
- Can be managed by using a Microsoft account only
- An Azure resource group can only contain one
Azure Resource Groups - Correct Answer A unit of management for resources in Azure. A container that
allows you to aggregate and manage all the resources for an app in a single manageable unit.
Azure Resource - Correct Answer A manageable item that's available through Azure. Virtual machines
(VMs), storage accounts, web apps, databases, and virtual networks are examples of this.
Azure Files - Correct Answer Offers fully managed file shares in the cloud that are accessible via the
industry standard Server Message Block (SMB) protocol. Supports SMB or NFS shares. It is extended by
Azure File Sync service.
Azure SQL Single Database - Correct Answer A resource type that creates a database in Azure SQL
Database with its own set of resources and is managed via a server. Each database is isolated, using a
dedicated database engine. Each has its own service tier within the DTU-based purchasing model or
vCore-based purchasing model and a compute size defining the resources allocated to the database
engine.
NOTE:
- A good solution when your data is in a relational format.
- Not optimized for graph data
_ Works best for transactional systems
- Allows hosting of only one database in Azure SQL
,Azure SQL Transparent Data Encryption (TDE) - Correct Answer Encrypts the contents of individual
databases. Encrypts the data at-rest and is enabled by default on newly created databases. Supports
Bring Your Own Key (BYOK), managed by customers.
Azure Cost Management - Correct Answer An Azure product that provides a set of tools for monitoring,
allocating, and optimizing Azure costs.
Note:
- Price is Free to Azure customers.
Azure Key Vault - Correct Answer A centralized cloud service for storing your applications' secure keys,
certificates, and other secrets. It helps you control your applications' secrets by keeping them in a single,
central location and by providing secure access, permissions control, and access logging capabilities.
NOTE:
- Used to securely store secrets, SQL database connection strings, and certificates
Azure Network Security Group (NSG) - Correct Answer Used to filter network traffic to and from Azure
resources in an Azure virtual network. It contains security rules that allow or deny inbound network
traffic to, or outbound network traffic from, several types of Azure resources. For each rule, you can
specify source and destination, port, and protocol.
NOTE:
- Can be attached to VMs
- Can allow network connectivity between NICs from batch application groups
- Can be used to deny network connectivity from other VMs or groups
7 layers of the OSI model - Correct Answer The layers for this are:
1. Physical
2. Data Link
3. Network
4. Transport
5. Session
6. Presentation
7. Application
,Azure SQL: Database Sharding - Correct Answer A type of database partitioning that separates very
large databases into smaller, faster, more easily managed parts.
Azure SQL: Database Elastic Pools - Correct Answer Provides a mechanism to scale compute power up
or down for SQL databases as needed. Multiple databases are on a single server and can share
resources, which saves costs.
Note:
- They are a cost-effective solution to manage and scale multiple databases that have varying and
unpredictable usage demands
- This service is completely managed by Azure, not requiring any DBA work to manage the servers
- Does not require server or operating system management
Azure SQL Elastic Database: Tools - Correct Answer These are used to manage database shard maps,
and include the client library, split-merges, pools, and queries.
Azure Cosmos DB - Correct Answer Globally distributed planet scale database that supports NoSQL
options, real-time access, multi-region writes, data distribution to any Azure region, and can scale
storage and throughput.
NOTE:
- Schema-less multi-model database
Azure SQL: Database service tiers - Correct Answer There are 3 types of these for using databases in
Azure:
1. General Purpose
2. Business Critical
3. Hyperscale
Azure SQL: Purchasing models - Correct Answer There are 2 types of these for buying Azure databases:
1. DTU - database transaction unit
2. vCore - virtual cores
, Azure SQL: Always On availability group - Correct Answer Supports the failover environment for SQL
databases. Copies data between replicas, from primary to secondary (read-only).
Note:
- This solution provides failback to the original site without additional work (such as log shipping).
Azure Data Lake Storage - Correct Answer A centralized repository that allows you to store all your
structured and unstructured data at any scale. It is a hyperscale repository for Big Data workloads. It
allows you to capture data of any size and type.
NOTE:
- Stores data only, it cannot copy data.
- It is unsuitable for graph data since data relationships cannot be determined
- Can load data directly into Azure Synapse
- Can create external tables in the data warehouse and use PolyBase to load the data
Azure Data Factory - Correct Answer Cloud-based extract-transform-load (ETL) and data integration
service that allows you to create data-driven workflows for orchestrating data movement and
transforming data at scale. It is a data integration service that allows you to create workflows for
transforming and moving data.
NOTE:
- It can help to develop graphical data transformation logic without writing code
- It can protect data against schema drift
- It manages data, it cannot store it.
- Used for transferring data between Data Lake Storage Gen1 and Gen2.
Azure Blob Storage - Correct Answer Storage service for very large unstructured non-text based data
objects, such as photos, video files or backups. The data is encrypted at rest by default for all new
storage accounts.
Azure Archive access tier storage - Correct Answer A storage level in Azure designed for long-term
archiving of infrequently-used data that can tolerate several hours of retrieval latency, and will remain in
there for at least 180 days.
