Explanation
The MHO-170 is equipped with 2 power supplies, making option A correct - this dual power supply design provides redundancy and ensures continued operation if one supply fails. Option B (1) and C (1 with option for 2) are incorrect because the unit ships with two supplies as a standard configuration, not a single or optional setup. Option D (4) overstates the count; that number of power supplies would be more typical of larger, enterprise-grade chassis systems rather than the MHO-170's form factor.
Memory tip: Think "MHO = Must Have twO" - the device has 2 power supplies built in for built-in redundancy.

Anastasia B.Jun 26, 2026The answer is A, 2 power supplies. The MHO-170 ships with dual redundant power supplies as a standard hardware configuration, so there is no single-PSU base model or optional upgrade path involved, which rules out B and C immediately, and 4 is simply not how this unit is built.
Lena V.Jun 29, 2026Correct on the redundancy, but worth noting for exam purposes that the question is really testing whether you know this is standard, not optional, so if they phrase it as "how many PSUs does the MHO-170 include by default" the answer logic stays the same.
Nina C.Jun 26, 2026I went with C first because so many enterprise appliances ship with one power supply and let you add a second as an upgrade, so that felt like the safe middle-ground answer. What changed my mind was going back to the MHO-170 spec sheet and seeing that the unit ships with 2 power supplies already built in, not as an add-on. That redundancy is baked into the design from the start, which makes sense given that the MHO line is aimed at high-availability deployments where a single PSU failure cannot take down the gateway. So the answer is A, 2 power supplies, not 1 with an option to expand.
Anastasia B.Jun 26, 2026Good catch on the spec sheet, and that distinction between "ships with redundancy" versus "supports optional redundancy as an upgrade" is exactly the kind of wording the exam uses to trip you up, so it is worth underlining for anyone still drilling that objective.
Lena V.Jun 13, 2026The MHO-170 ships with 2 power supplies standard, so A is your answer, not something you have to configure or add as an option. This trips people up because some of the other units in that product line do offer a single PSU with an optional second, but the 170 is dual PSU out of the box. The exam will sometimes word the question to make C sound attractive if you have seen that pattern elsewhere in the lineup. Lock in A and move on.
Ingrid P.Jun 10, 2026Four power supplies, full stop, I have this on a dedicated card with the interval at 21 days and I have never missed it.
Nina C.Jun 12, 2026Ingrid, which question are we on? I want to make sure I am looking at the same one before I say anything, because the reason A is correct depends on the exact wording of what is being asked.
Samuel O.Jun 18, 2026One power supply, period, the MHO-170 ships single PSU standard.
Lena V.Jun 20, 2026Samuel, the MHO-170 actually ships with dual redundant power supplies as standard, which is what option A reflects, and the exam specifically tests that redundancy feature as a selling point of that unit. Single PSU is the optional stripped-down config, not the default.
