This “Azure AZ-900 Exam Study Notes Part – 5” blog series covers the continuation of the questions and answers I used for brainstorming and self-learning part of my exam preparation.
AZ-900 Exam Study Notes – Part 5
| 81 | What are the two types of DDoS service offered by Azure |
| A | Basic and standard |
| 82 | What is the maximum number of update domains you can configure for an availability set consisting of IaaS v2 VMs? |
| A | Azure Resource Manager allows you to configure up to 20 update domains for an availability set. |
| 83 | What is a recommended use case for Azure SQL? |
| A | Using Azure Database Migration Service, you can migrate directly from Microsoft SQL Server to Azure SQL. It is recommended by Azure to move your on-premises SQL Server instance to Azure SQL to improve efficiency and lower costs. |
| 84 | You have an Azure VM running Windows Server 2012 R2 with a single data disk of 1 TB in size. You need to create a file system volume of 3 TB in size. What should you do? |
| A | The only way to accomplish this objective is to create a Storage Spaces-based volume with a simple layout. This will yield usable space of 3 TB. 1 TB is the maximum size of a page blob, so you cannot increase the disk size. Attaching a single disk would yield at most 2 TB of usable space. |
| 85 | You can use an operating system disk of a virtual machine from an on-premises Hyper-V host to deploy an Azure virtual machine. |
| A | Yes, however, the disk must be the VHD format (not VHDX) and it must not exceed 1 TB in size. |
| 86 | What are the different disk types in Azure |
| A | HDD, standard SSD, Premium SSD and ultra disk |
| 87 | What are the advantages of Cosmos DB? |
| A | Cosmos DB is a globally scaled distributed database solution that offers very low latency, a range of tools to interact with the data, and infinite scaling to handle the demand. |
| 88 | You need to provide a customer time-limited access to the content of a blob container in an Azure Storage account. You must ensure that the access can be revoked without affecting other customers who access the same storage account. What should you do? |
| A | A shared access signature (SAS) is a URI that grants restricted access rights to Azure Storage resources. This token can have a time bond validity associated with it and can always be controlled with stored access policies. |
| 89 | What is Azure subscription |
| A | It is a billing entity that controls the costs of resources and services associated with it |
| 90 | What are Azure special regions |
| A | US DoD, China East, China North and Germancy Central and Germany North-east |
| 91 | What are azure storage solutions |
| A | Blog, Disk, Archival and file |
| 92 | What is the difference between Microsoft SQL Server and Azure SQL? |
| A | Azure SQL is a managed service, which means Microsoft takes care of all the hardware and maintenance tasks for running the database. You only have to worry about using the database for storing and retrieving data. |
| 93 | If you forget the password for the Azure VM, can you perform a password reset? |
| A | Yes, you can perform a password reset by using the VM Access and VM Access for Linux extensions. |
| 94 | What are the ways to extend direct connectivity to your on-premises networks? |
| A | Point-to-Site VPN connects individual computers to an Azure virtual network via a Secure Socket Tunneling Protocol (SSTP) tunnel over the Internet. A Site-to-Site VPN connects an on-premises network (with all of its computers) to an Azure virtual network via an IPSec tunnel over the Internet. Azure ExpressRoute connects an on-premises network via a private connection (point-to-point or IPVPN). |
| 95 | What are the valid destination services for Azure Database Migration Service? |
| A | Database Migration Service on Azure has a range of destinations that you can migrate your data to. These include Azure SQL, Azure SQL Server, and Cosmos DB. |
| 96 | Shutting down an Azure VM from within its operating system will result in a Stopped state. Will it still incur computing charges? |
| A | When you run Azure VMs, you pay for the compute time on a per-minute basis. The price for VMs is calculated based on their size, the operating system, and any licensed software installed on the VM. A running virtual machine requires allocation of Azure compute resources, so to avoid the corresponding charges, you should change its state to Stopped (Deallocated) whenever you are not using it. |
| 97 | What are the different blog pricing tiers |
| A | Hot, Cool and Archive |
| 98 | Which queuing mechanism is better suited for massive amounts of messages? |
| A | Azure storage queue |
| 99 | How many maximum slots are available with Azure Web Apps? |
| A | You can have up to 5 slots for some SKUs in Azure web app. |
| 100 | How many tenants can a single user belong to in Azure Active Directory? |
| A | One. Any user on Azure must belong to a single Azure tenant. Users can be guests in other tenants but always belong to just one |
