Overview of the Microsoft AZ-104 Exam

The Microsoft AZ-104 exam is designed to test your ability to manage Azure resources, including virtual machines, storage accounts, and networking configurations. It covers a wide range of topics, such as:

  • Managing Azure identities and governance
  • Implementing and managing storage
  • Deploying and managing Azure compute resources
  • Configuring and managing virtual networking
  • Monitoring and backing up Azure resources

VM resizing falls under the "Deploying and managing Azure compute resources" domain, making it a critical skill for any Azure administrator. Mastering this topic not only helps you pass the exam but also equips you with practical knowledge for real-world scenarios.

What is VM Resizing?

VM resizing refers to the process of changing the size of a virtual machine in Azure. This can involve increasing or decreasing the number of CPU cores, the amount of RAM, or even changing the VM series to better suit your workload requirements. Resizing is a common task for Azure administrators, as it allows them to:

  • Scale up resources to handle increased workloads
  • Scale down resources to reduce costs
  • Optimize performance based on application needs

However, resizing a VM is not as simple as clicking a button. It requires a deep understanding of what happens during the process, what is preserved, and what might change. This is where DumpsBoss comes in, providing comprehensive study materials and practice questions to help you master this topic.

What is Preserved After Resizing a VM?

When you resize a VM in Azure, certain aspects of the VM are preserved, while others may change. Understanding these details is crucial for ensuring a smooth resizing process. Let’s break it down:

1. Data Preservation

One of the most important aspects of VM resizing is data preservation. Fortunately, Azure ensures that all data stored on the VM’s disks (OS disk and data disks) is preserved during the resizing process. This means you don’t have to worry about losing critical files or applications.

2. Networking Configuration

The networking configuration of the VM, including its IP address, network interfaces, and associated settings, remains unchanged after resizing. This ensures that your VM remains accessible and connected to the same network resources.

3. VM Identity & Configuration

The VM’s identity, such as its name, resource group, and subscription details, is preserved. Additionally, any custom configurations, such as installed software, user accounts, and system settings, remain intact.

4. Licensing and Subscription Details

Azure ensures that your VM’s licensing and subscription details are preserved during resizing. This is particularly important for VMs running specialized software that requires specific licenses.

Potential Changes and Considerations

While many aspects of a VM are preserved during resizing, there are some potential changes and considerations to keep in mind:

1. Downtime

Resizing a VM typically requires a reboot, which means there will be some downtime. The duration of the downtime depends on the size of the VM and the changes being made.

2. Availability Zones

If your VM is deployed in an availability zone, resizing it may require moving it to a different zone. This could impact your application’s availability and performance.

3. Disk Performance

While the data on your disks is preserved, resizing a VM may affect disk performance, especially if you’re moving to a VM size with fewer resources.

4. Cost Implications

Resizing a VM can have cost implications, especially if you’re scaling up to a larger VM size. It’s important to monitor your Azure usage and costs to avoid unexpected bills.

Best Practices for Resizing a VM

To ensure a smooth and successful VM resizing process, follow these best practices:

1. Plan Ahead

Before resizing a VM, assess your workload requirements and choose the appropriate VM size. Use Azure’s pricing calculator to estimate costs and avoid surprises.

2. Test in a Non-Production Environment

If possible, test the resizing process in a non-production environment to identify any potential issues.

3. Monitor Performance

After resizing, monitor the VM’s performance to ensure it meets your workload requirements. Use Azure Monitor to track metrics such as CPU usage, memory usage, and disk performance.

4. Backup Your Data

Although data is preserved during resizing, it’s always a good idea to back up your data before making any changes.

5. Use Automation

Consider using Azure Automation or PowerShell scripts to streamline the resizing process and reduce the risk of human error.
