Which of the following statements are true regarding the above outputs? (Choose two.)

Answer options

• A. The unit is running a 32-bit FortiOS
• B. The unit is in kernel conserve mode
• C. The Cached value is always the Active value plus the Inactive value
• D. Kernel indirectly accesses the low memory (LowTotal) through memory paging

Correct answer: B, D

Explanation

Option B is correct because the output indicates the unit is not utilizing conserve mode features, while option D is correct as it describes how the kernel manages low memory. Option A is incorrect since the memory totals suggest a 64-bit architecture, and option C is false because Cached memory does not equal the sum of Active and Inactive memory.
