Q

Whats the Temporary disk?

A

his disk is stored on a physical drive on the host machine. It is not saved in Azure Storage, and might be deleted during reboots and other VM lifecycle events. Use this disk only for temporary data, such as page or swap files.

Q

Whats a Network Security Group (NSG)?

A

Used to allow/deny network traffic to the subnet. You can associate an NSG with an individual NIC or with a subnet. If you associate it with a subnet, the NSG rules apply to all VMs in that subnet.

Q

If you delete a VM what happens to the VHDs?

A

If you delete a VM, the VHDs are not deleted. That means you can safely delete the VM without losing data. However, you will still be charged for storage.

41
Q

What is a fault domain?

A

Fault domains define a grouping of virtual machines that share a common power source and network switch. By default, the virtual machines that are configured within your availability set are separated across up to three fault domains. A hardware issue in one of these fault domains does not affect every VM that is running your app.

42
Q

What is an Update Domain?

A

Update domains indicate groups of virtual machines and underlying physical hardware that can be rebooted at the same time. During planned maintenance, the order in which update domains are rebooted might not be sequential, but only one update domain is rebooted at a time.

43
Q

Max number of fault domains?

A

3 per region

44
Q

54
Q

PS: Create Availability Set

A

New-AzureRmAvailabilitySet

55
Q

What are the 3 load balancing methods available in Azure?

A
  1. Failover
  2. Performance
  3. Round Robin
56
Q

What are virtual machine scale sets (vmss) in Azure?

A

VM Scale Sets enable you to deploy and manage multiple VMs as a set. Instead of provisioning multiple individual VMs, you provision a Scale Set based on an image, just like a regular VM. The Azure platform then provisions and de-provisions VMs based on that image as needed.

57
Q

PS: Create Auto Scale Rule

A

New-AzureRmAutoScaleRule

58
Q

PS: Create Auto Scale Profile

A

New-AzureRmAutoScaleProfile

59
Q

What are the 4 Options for Storage Replication?

A
  1. Locally Redundant
  2. Geo-Redundant
  3. Read-Access Geo Redundant
  4. Zone Redundant
60
Q

What is Azure Redis Cache?

A

It gives you access to a secure, dedicated Redis cache, managed by Microsoft, and accessible from any application within Azure. (Recommended)

61
Q

What is Azure In-Role Cache?

A

This feature enables you to create a cache that’s specific to a cloud service. The cache is hosted by instances of a web or worker role, and can only be accessed by roles that are operating as part of the same cloud service deployment unit. The cache is clustered, and all instances of the role within the same deployment unit that hosts the cache become part of the same cache cluster. However, this option is no longer recommended and is only provided to support existing applications that have been built to use it.

Use Azure Redis Cache instead

62
Q

What is Azure Managed Cache?

A

This service is based on the Azure Service Fabric Cache engine. It enables you to create a distributed cache that can be shared by loosely-coupled applications. The cache is hosted on high-performance servers running in an Azure datacenter. However, this option is no longer recommended and is only provided to support existing applications that have been built to use it. For all new development, use Azure Redis Cache instead
