Please select an option to fill in the blank below.
After creating a virtual machine, you need to change the __________ to allow connections of the TCP port 8080 on the virtual machine.
Network Security Group (NSG)
Virtual network gateway
Virtual network
Route table
Answer explanation
Option 1 is the correct answer. After creating the virtual machine, it is necessary to set communication rules in the network security group. Network security group default settings do not allow all inbound connections on layer 4, so changing the network security group rules to allow all inbound connections from port 80/8080 to reach the VM is necessary.
Option 2 is incorrect. An Azure virtual network gateway is a VPN device within an Azure virtual network that is used to set up a site-to-site VPN connection between an Azure virtual network and a local network, or a VNet to VNet VPN connection. This is not used for communication control for virtual machines.
Option 3 is incorrect. A virtual network is a private, isolated network in Azure. It is used as a basic network for deploying Azure resources such as virtual machines. This is the network itself. It still requires the a NSG for communication control.
Option 4 is incorrect. A route table is a table of rules (routes) that specify how packets are routed through a virtual network. This sets the communication route between networks and is not used for communication control for virtual machines.

Your company is considering migrating from an on-premises environment to Azure. You need to estimate the cost savings of running your solution on Azure. Which tool is right for you?
Azure Pricing Calculator
Azure Advisor
Azure Reservations
Answer explanation
Option 2 is the correct answer. The Azure TCO Calculator helps you estimate the total cost over time of running your solution in Azure compared to your on-premises datacenter. For example, you can estimate the cost for one month, one year, two years, etc. when using Azure. Based on this calculation, you can compare the cost of using Azure with the cost of running your on-premises environment.
Option 1 is incorrect. The Azure Pricing Calculator is a calculator that allows you to estimate the cost of each Azure resource. This is used for detailed estimates of individual services. You can specify Azure resources and set the details such as VM type to estimate the charges, or you can estimate using service units.
Option 3 is incorrect. Azure Advisor provides recommendations such as reducing the cost of running Azure virtual machines.
Option 4 is incorrect. Azure Reservations is a service that offers discounted rates on certain Azure services. With Azure Reservations, you can save up to 72% compared with pay-as-you-go pricing.

Azure Services will be available to all Azure users during ____________.
Public preview
Private preview
Development
Enterprise Agreement (EA) Subscription
Answer explanation
Overall explanation
Option 1 is the correct answer. Services in public preview are available to all users. All users can evaluate the new features at this stage. Microsoft Customer Support Services will provide support for Azure Services during this period, but the normal Service Level Agreements do not apply to these Services.
Option 2 is incorrect. Services in private preview are only available to a limited number of users.
Option 3 is incorrect. Services under development are not available to users.
Option 4 is incorrect. An Enterprise Agreement (EA) subscription is a special form of contract that is only available to select users.

Select "Yes" if the following statement is true, otherwise select "No".
Each availability zone consists of a single data center.
Yes
No
Answer explanation
Overall explanation
The correct answer is "No".
Availability Zones are physically separate zones within an Azure region. Availability Zones are used to protect your applications and data from failures and losses that affect entire Azure data centers. Each availability zone consists of one or more data centers with independent power, cooling, and networking. It does not necessarily consist of a single data center.

Yes
Np
Answer explanation
Overall explanation
The correct answer is "yes".
Even if Azure resources are available in all regions, not all regions are available to all users. For example, regions specifically allocated to the US government are restricted from public use. Azure has several special regions that you can use when building applications that meet your compliance or legal objectives. These special regions include:
■US Gov. Virginia and US Gov. Iowa
These are physically and logically network-isolated instances of Azure used by US government agencies and partners, and operated by approved US personnel. They include additional compliance certifications such as FedRAMP and DISA.
■China East and China North
These regions are available through a unique partnership between Microsoft and 21Vianet, whereby Microsoft does not directly maintain the datacenters.
■Germany Central and Germany Northeast
These regions are available via a data trustee model whereby customer data remains in Germany under control of T-Systems, a Deutsche Telekom company, which acts as the German data trustee.

Select "Yes" if the following statement is true, otherwise select "No".
Availability Zones are used to replicate data and applications across multiple regions.
Yes
No
Answer explanation
Overall explanation
The correct answer is "No".
Availability Zones in Azure are used to replicate applications and data only within an Azure region. Availability Zones are physically separated within a single region to protect your applications and data in the event of a data center failure. Zone-redundant services replicate your applications and data across availability zones to protect your resources against single points of failure. That's why Azure delivers an industry-leading 99.99% VM uptime SLA in Availability Zones.
Therefore, Availability Zones are used for redundancy within a single region, not for replicating data or applications across multiple regions.

What are the characteristics of the cloud that can provide continuous user experience without downtime even when problems occur?
Redundancy, scalability, fault tolerance, and load balancing
Scalability
Elasticity
Agility
Answer explanation
Overall explanation
Option 1 is the correct answer. Fault tolerance is the ability of a system to remain available even if one of its components fails. Azure recommends configuring applications across multiple data centers based on fault-tolerant principles. Fault tolerance can be easily achieved by using the cloud.
Option 2 is incorrect. Scalability is the ability to manually expand resources in the cloud as needed.
Option 3 is incorrect. Elasticity is the ability to dynamically expand/reduce resources in the cloud without stopping the application.
Option 4 is incorrect. Agility is the ability to rapidly deploy and configure resources in response to changing application requirements.
