Answer :

Explanation:

Box 1: Yes -
There are different replication options available with a storage account. The ‘minimum’ replication option is Locally Redundant Storage (LRS). With LRS, data is replicated synchronously three times within the primary region.

Box 2: No -
Data is not backed up automatically to another Azure Data Center although it can be depending on the replication option configured for the account. Locally
Redundant Storage (LRS) is the default which maintains three copies of the data in the data center.
Geo-redundant storage (GRS) has cross-regional replication to protect against regional outages. Data is replicated synchronously three times in the primary region, then replicated asynchronously to the secondary region.

Box 3: No -
The limits are much higher than that. The current storage limit is 2 PB for US and Europe, and 500 TB for all other regions (including the UK) with no limit on the number of files.

Answer :

Explanation:

Box 1: No -
Not all Azure regions support availability zones.

Box 2: No -
Regions that support availability zones support Linux virtual machines.

Box 3: Yes -
Availability Zones is a high-availability offering that protects your applications and data from datacenter failures. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there’s a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures. Zone-redundant services replicate your applications and data across Availability Zones to protect from single-points-of-failure. With Availability
Zones, Azure offers industry best 99.99% VM uptime SLA.

This question requires that you evaluate the underlined text to determine if it is correct.
You plan to deploy 20 virtual machines to an Azure environment. To ensure that a virtual machine named VM1 cannot connect to the other virtual machines, VM1 must be deployed to a separate virtual network.
Instructions: Review the underlined text. If it makes the statement correct, select “No change is neededâ€. If the statement is incorrect, select the answer choice that makes the statement correct.

  • A. No change is needed
  • B. run a different operating system than the other virtual machines
  • C. be deployed to a separate resource group
  • D. have two network interfaces


Answer : A

Explanation:
Azure automatically routes traffic between subnets in a virtual network. Therefore, all virtual machines in a virtual network can connect to the other virtual machines in the same virtual network. Even if the virtual machines are on separate subnets within the virtual network, they can still communicate with each other.
To ensure that a virtual machine cannot connect to the other virtual machines, the virtual machine must be deployed to a separate virtual network.

This question requires that you evaluate the underlined text to determine if it is correct.
When you need to delegate permissions to several Azure virtual machines simultaneously, you must deploy the Azure virtual machines to the same Azure region.
Instructions: Review the underlined text. If it makes the statement correct, select “No change is neededâ€. If the statement is incorrect, select the answer choice that makes the statement correct.

  • A. No change is needed
  • B. by using the same Azure Resource Manager template
  • C. to the same resource group
  • D. to the same availability zone


Answer : C

Explanation:
A resource group is a logical container for Azure resources. Resource groups make the management of Azure resources easier.
With a resource group, you can allow a user to manage all resources in the resource group, such as virtual machines, websites, and subnets. The permissions you apply to the resource group apply to all resources contained in the resource group.
