SQL Server Always On Availability Group: This is a high availability and disaster recovery solution for SQL Server databases that uses Windows Server Failover Clustering (WSFC) and Availability Groups (AGs) as its core components. When running on AHV VMs, SQL Server Always On Availability Group can use native storage adapters instead of iSCSI initiators.
Oracle RAC: This is a clustered database system that provides high availability and scalability for Oracle databases. When running on AHV VMs, Oracle RAC can use native storage adapters instead of iSCSI initiators.
Exchange DAG: This is a group of up to 16 mailbox servers that hosts a set of databases and provides automatic database-level recovery from failures that affect individual servers or databases. When running on AHV VMs, Exchange DAG can use native storage adapters instead of iSCSI initiators.

Really? I thought the IP addresses were enough on their own.

Yup, subnet and VLAN are key for smooth migration.

Wait, are you saying VMs need the same VLAN? That seems off.

Definitely agree, VLAN config is a must too!

All AHV hosts need to be in the same subnet for sure.

I definitely remember something about VLANs being crucial for migration, but I’m a bit confused about the subnet part.

I feel like both hosts and VMs need to be in the same subnet, but I can't recall if that's strictly necessary for all cases.

I remember practicing a question about VM configurations, and I think having the VMs on the same VLAN is important too.

I think the AHV hosts need to be in the same subnet for migration to work, but I'm not sure about the VLAN requirement.

Wait, I'm a bit confused. Do the VMs themselves need to be on the same subnet and VLAN, or is it just the hosts? I want to make sure I don't overthink this.

Okay, I've got this. The two minimum prerequisites are that all AHV hosts must have IP addresses in the same subnet (A) and be configured on the same VLAN (B). Easy peasy!

Hmm, I think the key here is that the hosts and VMs need to be on the same network for live migration to work. I'll focus on options A and B.

This question seems straightforward, but I want to make sure I understand the key requirements for live migration. I'll need to review the networking configuration details.

Okay, let's break this down step-by-step. We have three different investments to consider, and the key is determining the level of control LM has over each one.

I'm just going to go with C and D. That way, at least I'll get half the points, right? Or is that not how it works? *sigh*

This is a trick question! The right answers are actually A and B. You need the hosts to be on the same subnet AND the same VLAN. Gotta love those tricky certification exams!

Yes, that's right! It's a tricky question, but important to know for the certification exam.

So, the minimum prerequisites for live migration to succeed are that all AHV hosts must be configured on the same VLAN and all VMs must have an IP address in the same subnet.

For live migration to succeed, all AHV hosts must be configured on the same VLAN and all VMs must have an IP address in the same subnet.
MA

No, VLAN and subnet are not the same thing. VLAN is a way to separate network traffic, while subnet is a way to divide a network into smaller parts.

I disagree, I think B and D are the right answers. Live migration requires the VMs and hosts to be on the same VLAN.

Hmm, I think options A and C are the correct answers. The VMs need to be on the same subnet, and the hosts need to be on the same subnet too.

I'm not sure about the VLAN requirement, but I know that having all VMs in the same subnet is definitely necessary for live migration to work.
