IMO, for minimum downtime it would be D Active/Active?, so it already has an HA setup running..

the correct answer is D https://www.ibm.com/garage/method/practices/manage/hadr-on-premises-app/

Selected Answer: D D is correct because the question is referring to the lower RTO with 'minimum downtime' so we can interpret it this way: HA = Active/Active RPO = synchronous data RTO = minimum downtime

The correct answer is D!

"Active/passive clustering is a solution approach to reduce system downtime. Two active clusters in different regions offer a high SLA level, but don’t support using synchronous replication for multiple cases."

D is the correct one, it is clearly stated here: https://www.ibm.com/garage/method/practices/manage/hadr-on-premises-app/

Selected Answer: A Option A is the best pick for reducing downtime while keeping data synchronization between data centers for seamless request flow.

The correct answer should be D since Active & Active is the best deployment method.

Answer D, becouse active/active is minumun RTO.

I would also say A is right, since the requirement is HA. Active/Active would kind of be fault tolerant which is not required. Read the questions carefully :)

The best design approach for high-availability applications to reduce downtime would be option A - Active/passive gives lower RTO and RPO. For RPO, data synchronization between the two data centers must be timely to support seamless request flow. Active/passive architecture means having a primary (active) and secondary (passive) instance of the application running in two separate data centers. The secondary instance is not being used but is kept current with data synchronization between the two data centers. In case of a failure or maintenance activity, the passive instance can be brought up to take over the workload without any data loss.

This approach gives a lower Recovery Time Objective (RTO) and Recovery Point Objective (RPO) because the passive instance is ready to take over the workload at any time. However, to keep request flow seamless, data synchronization between the two data centers must be timely. Active/active architecture means having multiple instances of the application running at the same time in different data centers. This approach gives a lower RTO and RPO but needs more complex implementation and data synchronization mechanisms.

Selected Answer: D For me only D really makes sense

they have mentioned it is ok to have minimum downtime.. considering that A/A setup is complex to set up and causes more ops issues.. correct ans would be A

Selected Answer: D Active/Active ALWAYS has a lower RTO than active/passive.

Selected Answer: D Explanation: RTO (Recovery Time Objective) means how fast the application needs to be back online after an outage. Active/active setups usually give a lower RTO, since both data centers are running at the same time, so there is no downtime during failover. RPO (Recovery Point Objective) means how much data can be lost in case of a failure. In an active/active setup, data sync between the two data centers must be timely (and near real-time) to make sure there is no data loss and to keep a seamless request flow.
