Why is it challenging to manage variable$-$sized key$-$value pairs within the fixed$-$size pages of SSD$?$

a$.$ Due to the limited capacity of the SSD

b$.$ Because the SSD firmware lacks the capability to handle variable sizes

c$.$ Because the key$-$value pairs need to be compressed

d$.$ Because it requires efficiently packing variable$-$sized data into fixed$-$size pages

CPU needs to interact with a fast I$/$O device. What is the potential downside of using interrupts for this scenario?

a$.$ Polling will become the primary method of interaction.

b$.$ The device driver will not be able to communicate with the device.

c$.$ The CPU will not be able to handle other tasks while waiting for the device.

d$.$ Interrupts will introduce overhead due to context switching and interrupt handling

What challenge do SSDs face due to their internal data placement and replacement mechanisms?

a$.$ Limited number of PE cycles

b$.$ None of the above

c$.$ Latency issues during read operations

d$.$ Read disturbance errors

What factors contribute to the advantage of block SSDs over key$-$value SSDs in terms of garbage collection $($GC$)$ operations?

a$.$ Efficient indexing structure maintenance

b$.$ Higher susceptibility to foreground GC

c$.$ Sorted data arrangement facilitating GC candidates

d$.$ Lower likelihood of space amplification for small key$-$value pairs

e$.$ Reduced latency for update requests waiting for GC completion
