A company is using XtremlO for their RecoverPoint environment. They have approximately 100 GB of cumulative changes per day with the change being constant throughout
the day. The company has a requirement to roll back 48 hours.
How should the Journals be sized and how should the copy policy be configured to ensure maximum protection with the least amount of storage used?

Calculate Daily Changes: With 100 GB of cumulative changes per day, the total amount of changes over two days would be 200 GB.
Determine Journal Size: The Journal size must be large enough to store all the changes for the required rollback periD. Therefore, a Journal size of 200 GB is necessary.
Set Protection Window: The ''Required Protection Window'' should be set for 2 days to match the rollback requirement.
Configure Copy Policy: The copy policy should be configured to ensure that the Journal maintains the point-in-time images for at least 48 hours.

Wait, how can 5 GB be enough for 48 hours? That sounds risky!

Definitely agree with D, it balances protection and storage well.

I'm not sure about 40 GB, that feels a bit low for safety.

200 GB seems excessive for that amount of data change.

I think option D makes the most sense for 48 hours of rollback.

I have a feeling that 40 GB could be the right choice since it seems to balance the storage and the protection window, but I’m not entirely confident.

I recall that the 'Required Protection Window' should match the rollback time, which is 48 hours here. Does that mean we need to consider the daily changes too?

I think we practiced a similar question where we had to determine the journal size based on daily changes. I feel like 200 GB might be too much, though.

I remember that the cumulative changes per day are crucial for sizing the journals, but I'm not sure how to calculate the exact size needed.

I've got this! The key is to size the journal to accommodate the 48-hour rollback window, which means 40 GB is the right choice. And setting the 'Required Protection Window' to 2 days will ensure we have the coverage we need. Option D is the way to go.

I'm a bit confused on this one. The daily change rate is constant, but I'm not sure how that translates to the journal size and copy policy. I'll need to review the details more carefully.

Alright, this is straightforward. The daily change rate is 100 GB, and we need to cover 48 hours, so 40 GB should do the trick. I'm going with option D.

Okay, let's see. 100 GB of changes per day, and a 48-hour rollback requirement. I'm thinking option D might be the way to go, but I'll double-check the math to be sure.

Hmm, this seems like a tricky one. I'll need to think through the daily change rate and the required rollback window to figure out the right journal size and copy policy.

Okay, I think I've got this. Reused services typically have lower security, performance, and reliability requirements, so the Service Reusability principle should decrease demands on infrastructure. I'll go with option B.

I'm a bit stuck on this one. I know the basics about fiber-optic cables, but I'm not sure which specific statements are true. I'll have to review my notes and try to eliminate the incorrect options.

This looks like a straightforward data modeling question. I'll need to carefully analyze the information provided about the Order Header and Order Detail to determine the number of RETs.

Wait, is this an exam question or a game of Tetris? 'Sizing Journals' sounds like a whole new level of challenge.

Ah, the old 'least amount of storage used' conundrum. I bet the answer is hidden in some obscure vendor documentation. *sigh*

I like how option C has the 2-day protection window, but 10 GB seems a bit low. Gotta go with D on this one.

Veronika: Let's go with option D then for maximum protection with the least storage used.

Yeah, but 10 GB might not be enough. I'm leaning towards option D.

DA

I'm not sure, but I think D) 40 GB with the 'Required Protection Window' set for 2 days could also be a good option.

200 GB? That's way overkill. We're talking about a 48-hour rollback, not a year's worth of data.

I disagree, I believe the answer is C) 10 GB with the 'Required Protection Window' set for 2 days.
CH

Hmm, 5 GB? That's barely enough to hold a single day's worth of changes. I think option D is the way to go here.
CA
Casie

Agreed, option D provides a good balance of protection and storage usage.
LE

Yes, 40 GB should be able to hold 2 days worth of changes comfortably.
AS

Option D with 40 GB seems like a better choice for the required protection window.
