VMCE Replication and Disaster Recovery Questions and Answers — Questions and Answers
Question 1: An administrator needs to perform scheduled maintenance on the production SAN, requiring a temporary migration of critical VMs to the DR site. To ensure no data is lost during this process, which Veeam replication feature should be used?
- Failover Now
- Failover Plan Testing
- Restore from Replica
- Planned Failover (Correct answer)
Correct answer: Planned Failover
Planned Failover is designed for scenarios like datacenter maintenance or controlled migrations. It performs a final synchronization of the source VM, shuts it down gracefully, and then starts the replica at the DR site, ensuring zero data loss. 'Failover Now' is for unplanned disasters and may result in data loss up to the last restore point.
Question 2: When configuring Veeam's Continuous Data Protection (CDP), which component must be installed on the VMware vSphere cluster to intercept and redirect I/O operations from the source VM to the CDP Proxy?
- Veeam Guest Agent
- vSphere APIs for I/O Filtering (VAIO) driver (Correct answer)
- Veeam Management Agent
- Network Extension Appliance
Correct answer: vSphere APIs for I/O Filtering (VAIO) driver
Veeam CDP leverages VMware's vSphere APIs for I/O Filtering (VAIO) framework. A special Veeam I/O filter driver is installed on the ESXi hosts within a vSphere cluster to intercept and split VM I/O without using traditional snapshots, enabling near-synchronous replication.
Question 3: Which of the following is a primary function of a Veeam Failover Plan?
- To define the RPO and RTO for individual replication jobs.
- To orchestrate the failover of multiple VMs in a specific boot order and set time delays. (Correct answer)
- To configure network traffic throttling rules for replication jobs.
- To create application-consistent replicas using guest processing.
Correct answer: To orchestrate the failover of multiple VMs in a specific boot order and set time delays.
A Failover Plan is an orchestration tool used to manage disaster recovery for multi-tier applications. Its main purpose is to define the sequence in which VMs are powered on at the DR site and to set delays between them, ensuring dependencies (like a database starting before an application server) are met.
Question 4: A company has a production site with the network 192.168.1.0/24 and a DR site with the network 10.0.1.0/24. They are replicating a critical application server. To ensure the replica is accessible on the DR network after a failover, which replication job setting must be configured?
- Seeding
- Network Mapping
- Traffic Encryption
- Replica Re-IP (Correct answer)
Correct answer: Replica Re-IP
The Replica Re-IP feature allows an administrator to create rules that automatically change the IP address of a VM replica when it is powered on during a failover event. This is essential for ensuring the VM is functional and accessible on a different subnet at the disaster recovery site.
Question 5: After performing a failover to a VM replica at the DR site, what is the process of returning operations and any changes made on the replica back to the original source VM in the production site called?
- Permanent Failover
- Failback (Correct answer)
- Undo Failover
- Reverse Replication
Correct answer: Failback
Failback is the process of returning a workload from the replica at the DR site back to the original VM at the production site (or a new location) once the primary site is operational again. This process involves synchronizing the data changes that occurred while the replica was active.
Question 6: A financial institution needs to protect its tier-1 trading application. The business has specified a Recovery Point Objective (RPO) of less than 15 seconds to minimize data loss. Which Veeam replication technology should be used to meet this requirement?
- Continuous Data Protection (CDP) (Correct answer)
- Standard Snapshot-based Replication
- Backup Copy Job
- Storage Snapshot Replication
Correct answer: Continuous Data Protection (CDP)
Continuous Data Protection (CDP) is specifically designed for tier-1 workloads with very low RPO requirements, measured in seconds. It uses VAIO to replicate I/O continuously without the overhead of VM snapshots, whereas standard snapshot-based replication is limited to RPOs of several minutes at best.
