Cisco Exam 700-905 Topic 2 Question 62 Discussion

Actual exam question for Cisco's 700-905 exam

Question #: 62
Topic #: 2

Which three configurations for read caching in Cisco HyperFlex are valid? (Choose three.)

ABattery-Initiated Read-back (default): Only read data and most commonly used data are deposited in the Level 4 read-back cache

BWrite-back (default): Only write information and most commonly used information are deposited in the cache

CWrite-through (install option for VDI): Only most commonly used data is cached: optimizing VDI performance

DNo caching (SSD): With all-flash nodes; because there is little difference in read speeds between SSDs

ELevel 4 cached (SSD): With semi-flash nodes; there is a large difference in read speeds between SSDs

FWrite-first (default for VDI): Infrequently used data is cached: freeing system resources for VDI performance

I think B and F are definitely valid options for read caching, as they optimize performance based on data usage.

I'm leaning towards B, E, and F as the valid configurations for read caching.

I agree with A and C, but I believe D should also be included as a valid configuration.

Ah, I see what you mean. 'Write-first' must be the default for VDI workloads, where the focus is on optimizing VDI performance rather than general caching. It makes sense that they'd prioritize caching infrequently used data in that case.

Haha, well if that's the case, I'm going with the 'Quantum Entanglement Cache' as my fourth option. It's the one where data just appears out of thin air.

You make a good point. 'Level 4 cached' does seem like a reasonable option for semi-flash nodes. As for the 'Write-first' option, I'm guessing that's a configuration for VDI workloads, where you want to prioritize caching infrequently used data to free up system resources for the VDI performance.

I also think 'Battery-Initiated Read-back' is a valid configuration for read caching.

Yes, I agree. 'Level 4 cached' would definitely benefit semi-flash nodes.

Ah, the Magical Unicorn Cache, where data is stored in the dreams of mythical creatures. That's the one I'm betting on.

Haha, yeah, can you imagine if they threw in a 'Magical Unicorn Cache' option just to mess with us? That would be brutal.

Hmm, I'm not too sure about the 'No caching' option. Wouldn't it make more sense to have some level of caching, even on all-flash nodes, to improve performance? I think 'Level 4 cached' might be a valid option for semi-flash nodes, where there's a larger difference in read speeds between SSDs.

Yeah, I'm pretty sure 'Write-back' is also a valid option, where only write information and commonly used information are cached. And 'No caching' is valid for all-flash nodes since there's little difference in read speeds between SSDs.

I agree, the 'Write-first' and 'Level 4 cached' options are a bit confusing. But I think I know the answer to this one. The default read caching configuration is 'Battery-Initiated Read-back', which caches read data and commonly used data. And 'Write-through' is an install option for VDI, which caches commonly used data to optimize VDI performance.

This question seems to be testing our knowledge of the different read caching configurations in Cisco HyperFlex. I'm a bit unsure about the 'Write-first' and 'Level 4 cached' options, as I haven't come across those terms before.
