ACA exam — how hard is the SBC configuration section really?

The media realm configuration questions are tricky because the answers often hinge on network topology assumptions that aren't spelled out in the question. Make sure you're thinking about NAT traversal and media anchoring scenarios specifically — those came up a lot.

Lawful intercept and SIP recording are tested but not deeply. I got maybe 3–4 questions on compliance topics total. Don't spend more than a few hours there — put your time into SBC and IP profile logic instead.

The SBC section is definitely weighted heaviest in my experience. I'd estimate about 40% of the questions I saw were SBC-related. If you're already at 72% overall, going deeper on SBC logic will probably push you over 80% comfortably.

2 hours a day for 2 weeks on top of 3 weeks of prior study should be more than enough. I passed with a 79% after about 5 weeks total and my SBC background was similar to yours. The exam rewards people who understand the why rather than just the configuration steps.

Quick update on my end — I've been grinding through practice questions for the past two weeks and just hit 78% on a full mock run, which honestly surprised me. The SBC config section wasn't as brutal as I expected coming in, but the aca/questions/high availability redundancy stuff tripped me up way more than I thought it would. Like you'd think after 5 years I'd have that cold, but the exam goes pretty deep on the specifics.

I'm sitting the real thing next Friday. If you're already working with the gear daily I wouldn't stress too much, it's more about knowing where AudioCodes draws the lines on terminology than anything exotic.

The SBC configuration section caught me off guard too, and I also came in thinking my hands-on experience would carry me through. It didn't, at least not completely. The exam goes deeper on the MediaPack and Mediant parameter specifics than you'd expect — things like SRD and IP Group relationships, routing rule precedence, and how the SBC handles codec negotiation in edge cases. Knowing how to configure something in production doesn't always mean you can answer a "why does this happen" question under time pressure.

What actually helped me close those gaps was working through an aca practice test a few weeks before the real thing. The questions on Teams Direct Routing and SBC leg behavior were surprisingly close to the format and difficulty I saw on the actual exam — not just "what does this CLI command do" but scenario-based stuff where you have to trace why a call fails or which parameter is misconfigured. That's where my weak spots showed up fast. I kept getting tripped up on the SIP manipulation rules section, which I'd basically ignored in my day-to-day work because I handled that stuff mostly through templates.

With your background you'll probably move through the basics quickly, but don't skip the QoS and high availability sections. Those felt more textbook-heavy than the config sections and less tied to what you'd actually do in a DR scenario at a customer site. Budget an extra few days just for those.

Just passed last week so I can tell you — the SBC config section is trickier than it looks, even with hands-on experience. The gotcha for me wasn't the basic dial plan stuff, it was the redundancy scenarios. I kept second-guessing myself on failover behavior until I drilled into aca/questions/high availability redundancy and it finally clicked. Those questions are way closer to what you'll see on the actual exam than I expected.

Honestly if you're already doing Direct Routing deployments you've got the practical side covered. The exam just wants you to be precise about it. Don't assume your field experience translates directly to how they phrase things — slow down on the HA questions and you'll be fine.

I'll be honest, I failed it my first time and I was pretty embarrassed given I'd been doing SBC work for years. The problem wasn't the configuration stuff — that part actually felt comfortable. What caught me off guard was the theoretical depth on topics I'd always just clicked through in the GUI without really thinking about. HA clustering especially. I knew how to set it up but I didn't fully understand the why behind the sync mechanisms and failover logic. I spent a week on the aca/questions/high availability redundancy material before my second attempt and it made a real difference.

Second time around I passed and honestly it wasn't even that close. If you've got hands-on experience you're ahead of most people, but don't assume that's enough. Go back to basics on the protocol-level stuff, especially SIP dialog handling and media flow under failure conditions. The exam wants you to know what's happening under the hood, not just which menu to click.
