Q #1 When you open
portal on the VM you see public IP address and when you try to RDP with the
help of Public IP address it didn’t work and you have been through NSG and all
still not working ?
Well if you mean all settings are good and IP should work
for RDP but still not working then for sure this IP is not associated to NIC of
the VM but to the LB and that’s why prompting on the VN overview. We need to
check if any NAT rule is defined for port forwarding and use that for RDP.
Q #2 What is
Accelerated networking and how it helps application ?
Accelerated networking enables single root I/O
virtualization (SR-IOV) to a VM, greatly improving its networking performance.
This high-performance path bypasses the host from the datapath, reducing
latency, jitter, and CPU utilization, for use with the most demanding network
workloads on supported VM types.
Q #3 Is there any
restriction or have you face any issue while adding machine to existing AV-set
?
All other series could not be in the same availability set
because they require a specific hardware. A8/A9 VM size can't be mixed due to
requirement on dedicated RDMA backend network.
You can add more VMs to the availability set later, but you
need to know what VM sizes are available on the hardware. Use Get-AzVMSize to list all the available sizes on the
hardware cluster for the availability set.
Get-AzVMSize `
-ResourceGroupName
"myResourceGroupAvailability" `
-AvailabilitySetName "myAvailabilitySet"
Q #4 Could you define the recovery process of Azure VM in case of VM stuck due to windows update or system file check or on please wait screen or anything like that.
1.
Stop
the affected VM.
2.
Create
a snapshot for the OS disk of the VM.
3.
Create
a virtual hard disk from the snapshot.
4.
Attach
and mount the virtual hard disk to another Windows VM for troubleshooting
purposes.
5.
Connect
to the troubleshooting VM. Edit files or run any tools to fix issues on the
original virtual hard disk.
6.
Unmount
and detach the virtual hard disk from the troubleshooting VM.
7.
Swap
the OS disk for the VM.
Q #5 For a standard
managed disk, will I be charged for the actual size of the data on the disk or
for the provisioned capacity of the disk?
You're charged based on the provisioned capacity of
the disk.
Q #6 Can I take an
incremental snapshot of a managed disk?
No. The
current snapshot capability makes a full copy of a managed disk however
incremental is in preview and available in few regions only.
Q #7 Can VMs in an availability set consist of a combination of managed and unmanaged disks?
No.
The VMs in an availability set must use either all managed disks or all
unmanaged disks. When you create an availability set, you can choose which type
of disks you want to use.
Q #8 What kind of Role-Based Access Control support is available for Managed Disks?
Managed
Disks supports three key default roles:
·
Owner: Can manage everything, including access
·
Contributor: Can manage everything except access
·
Reader: Can view everything, but can't make changes
Q #9 Can I create a copy of my managed disk?
No
we cannot but we can take a snapshot of their managed disks and then use the
snapshot to create another managed disk.
Q #10 Can I use GPT partitioning on an Azure
Disk?
Generation
1 images can only use GPT partitioning on data disks, not OS disks. OS disks
must use the MBR partition style.
Stay Tuned for more !!!!
