Azure Networking Flashcards
In Azure networking, can you have a peered connection between two vNets in different regions?
Yes, you can peer virtual networks (vNets) across different Azure regions using global virtual network peering. This allows resources in each vNet to communicate directly with each other across regions. Note that data transfer costs apply for cross-region peering.
In Azure will taking a backup of a VM help with the availability of the VM?
Taking a backup of an Azure VM does not directly enhance the availability of the VM itself; rather, it supports business continuity and disaster recovery. Backups allow you to restore a VM to a previous state if it encounters issues, but they don’t prevent downtime or increase the VM’s operational uptime. For availability improvements, focus on options like:
Availability Sets: Protect against downtime during planned maintenance and hardware failures within a single data center.
Availability Zones: Spread VM instances across multiple datacenters within a region, providing protection from entire data center failures.
Azure Site Recovery (ASR): Offers disaster recovery by replicating workloads to another region, ensuring the service continues during regional outages.
Backups are crucial for restoring data and configurations, complementing these availability strategies in a full continuity plan.
