A disaster recovery team learned of several mistakes that were made during the last disaster recovery parallel test. Computational resources ran out at 70% of restoration of critical services.
Which of the following should be modified to prevent the issue from reoccurring?
D

It has to be Recovery service level imo
I want to concur, but I feel like that would validate the ridiculousness of the question... How exactly does one "run out" of the computational aspect of resources? I've run out of disk space before, and I have certainly maxed out my CPUs/GPUs, but I cannot ever recall a time when my CPU came back and said, 'sorry, I've done all I can; it was just too many instructions'. Also, if you can just change your RTO or RPO to fit what you happen to have on hand time, labor, or resource -wise ...then I think I have a simple solution for everyone's RTO and RPO problems.
RPO failed at 70%.
Great point!!
Recovery Service Level: RSL is a percentage measure (0-100%) of how much computing horsepower based upon a percentage of the production system that you will need during a disaster.
The recovery service level is a percentage measurement (0-100%) of how much computing power is necessary based on the percentage of the production system needed during a disaster.
Recovery Point Objective (RPO): amount of data that can be lost without irreparable harm Recovery Time Objective (RTO): Maximum amount of time performing a recovery can take. Mission-essential Functions (MEF): Understanding what systems are critical (as part of BIA). Effective risk management begins with the identification of mission essential functions that could cause the whole business to fail if they are not performed. Recovery Service Level (RSL): It is important to consider that only portions of a complete system may be critical, and this should be reflected in the recovery plans. Only C makes sense as something that can be modified in order to prevent this scenario of CPU exhaustion, so we can run only what is required for the system to performs its MEFs.
Parallel Test - Uses recovery systems that are built and tested to see if they can perform actual business transactions to support key processes. Recovery Service Level (RSL) - A metric that is displayed as a percentage of how much computing power will be needed during a disaster. Assuming you can't touch RPO, then the answer should be D (but I;m not 100% on this, as the question is kinda crap :))
This question is crazy, considering most of the proposed "solutions." We were bad at this last time, so you just need to change your expectations or make it easier. -.- Recovery point objective doesn't change because it is always the same objective, fail-over services. RTO - Time has nothing to do with running out of "computational power" Mission-essential functions should have been verified and approved by senior management and executive leadership, so it may be viable to tell some, "Nah you aren't that important because I have to take some cuts" Recovery service level = is associated with an SLA if outsourced, and if internal, it is the executive's leadership signing that this needs to happen, "authorizing any resources required to make it happen." In reality world with an actual budget, I would pick C. However, adjusting how much resources are needed to be purchased or used seems like a "book" answer, because the budget doesn't exist, right? :)
D is correct
Recovery Service Level also involves the discussion of allocation of CPU, memory, and storage to handle the workload during the recovery process.
To prevent the issue of computational resources running out during a disaster recovery parallel test, the relevant parameter to consider modifying is: D. Recovery service level
AenAllAin has the right thought process, you cannot just change the fundamental truth of your RPO, RTO, and RSL... you can't just change them to better fit a different disaster. I think C is the outlier here, kind of like one of those obvious CompTIA questions but not obvious. All the dumps I've gone through either choose B or D but one says C. I picked B the first time I took this and failed, going with C for round 2.
