CompTIA CV0-004 Exam - Topic 6 Question 29 Discussion

Actual exam question for CompTIA's CV0-004 exam

Question #: 29
Topic #: 6

[All CV0-004 Questions]

A systems administrator is provisioning VMs according to the following requirements:

* A VM instance needs to be present in at least two data centers.

. During replication, the application hosted on the VM tolerates a maximum latency of one second.

* When a VM is unavailable, failover must be immediate.

Which of the following replication methods will best meet these requirements?

ASnapshot

BTransactional

CLive

DPoint-in-time

Show Suggested Answer

Suggested Answer: D

A system that keeps all different versions of software separate from each other while providing access to all of the versions is best described by Code versioning. Code versioning systems, such as Git, allow developers to keep track of changes, revert to previous states, and manage multiple versions of codebases.

Point-in-time is a no-go; it won't meet the two data center requirement.

Wait, can live replication really handle that latency? Sounds risky!

Definitely not snapshot; that won't meet the immediate failover requirement.

I think transactional replication could work too, but not as fast.

Live replication is the way to go for low latency!

Point-in-time replication seems too slow for this scenario, given the one-second latency tolerance. I lean towards live replication as well.

I practiced a similar question, and I think snapshot replication wouldn't meet the immediate failover requirement.

I'm not entirely sure, but I feel like transactional replication could work too, especially with the latency requirement.

I remember studying replication methods, and I think live replication might be the best option since it allows for real-time data transfer.

Okay, I think Live replication is the way to go. It can handle the low-latency and immediate failover, and if configured properly, it should be able to replicate across multiple datacenters as well.

I'm a bit confused on the differences between the replication methods. I'll need to review the details of each one to determine which best fits all the requirements.

Live replication seems like the obvious choice here to meet the low-latency and failover requirements, but I'll need to double-check that it can also handle the multi-datacenter aspect.

Hmm, the one-second latency limit during replication is a key constraint. I'll have to think about which method can meet that while also providing immediate failover.

This seems like a tricky one. I'll need to carefully consider the requirements around latency, failover, and multi-datacenter replication.

Live replication sounds risky to me. Imagine if the network hiccups - your app could be down for more than a second. Better play it safe with Point-in-time.

I would go with Point-in-time as well, better safe than sorry.

Hmm, I'm not sure Live is the best option. With the need for cross-data center replication, Point-in-time might be a better fit to ensure data consistency.
