Quick Answer
The answer is RAM and Cache. Both are examples of volatile memory because they require a constant electrical charge to maintain stored data; once power is cut, all information is immediately lost. RAM, or Random Access Memory, temporarily holds actively used programs and data for quick CPU access, while Cache is a smaller, faster volatile memory that stores frequently accessed instructions to speed up processing. On the CompTIA ITF+ FC0-U61 exam, this concept tests your understanding of memory hierarchy and the fundamental difference between volatile and non-volatile storage. A common trap is confusing RAM with storage drives like SSDs or HDDs, which are non-volatile and retain data after shutdown. To remember, think of volatile memory as “volatile like a flame—it disappears when the power goes out,” and always associate RAM and Cache with temporary, power-dependent storage.
This FC0-U61 practice question tests your understanding of it concepts and terminology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are examples of volatile memory?
RAM
RAM is volatile memory.
Cache
Cache is volatile memory.
Hard Drive
Why wrong: Hard drives are non-volatile storage.
SSD
Why wrong: SSDs are non-volatile storage.
ROM
Why wrong: ROM is non-volatile.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
RAM
RAM (Random Access Memory) is volatile because it requires constant electrical power to retain data; once the system is powered off, all stored information is lost. This characteristic makes RAM ideal for temporary storage of actively used data and program instructions during operation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

ROM is non-volatile.
Common exam traps
Cisco often tests the distinction between volatile and non-volatile memory by including storage devices like SSDs and hard drives as distractors, exploiting the common misconception that 'memory' and 'storage' are interchangeable terms.
Detailed technical explanation
Volatile memory, such as DRAM (Dynamic RAM) used in most RAM modules, stores data in capacitors that leak charge over milliseconds, requiring periodic refresh cycles (typically every 64 ms) to maintain data integrity. Cache memory, often implemented as SRAM (Static RAM), uses flip-flop circuits that hold data as long as power is supplied but do not require refreshing, offering faster access times than DRAM. In real-world scenarios, volatile memory explains why unsaved work is lost during a power outage, while non-volatile storage like SSDs or hard drives preserves files across reboots.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
