Free Isaca CCOA Actual Exam Questions

Makes sense to pick D because turning off unnecessary features cuts down attack points more than just tweaking user rights. D seems the broadest hardening method here.

It’s D, since reducing enabled features cuts more risk than just access limits.

A/B? While A is the usual report, B could fit if they include a high-level overview. But detailed physical security seems less typical, so A still looks stronger here.

D imo, B talks about physical security which isn't typically covered in vulnerability assessments focused on IT systems. A is more straightforward with just the vulnerabilities and severity levels.

Probably A. The question emphasizes having all code, diagrams, and documentation, which points to full knowledge testing since the tester starts with everything upfront. Partial knowledge usually means some info is missing, so D doesn’t seem right here. Unlimited scope (B) refers more to the range of systems tested rather than the info given. No knowledge (C) is clearly not the case since the tester has all the materials.

A imo, full knowledge testing means having all the info upfront, including code and diagrams. Without live system access mentioned, it still fits better than partial or no knowledge options here.

Maybe C makes sense here. Before worrying about what the tool can detect, you should first know which vulnerability categories are relevant to the assets being tested. If you don’t understand what types of vulnerabilities actually apply to your assets, then figuring out what the tool can detect or how many it finds doesn’t help much. So nailing down the possible categories for those asset types feels like the logical first step to me.

It’s D for me—knowing what categories the scanning tool can actually detect upfront helps set realistic limits before diving into asset types or total vulnerabilities. Otherwise, you might chase gaps the tool can’t find anyway.

D imo, a DNS sinkhole lets you catch and control suspicious traffic without cutting off normal DNS, so it stops exfiltration while keeping the network working fine. Blocking all outbound DNS (C) is too harsh.

D. Using a DNS sinkhole is a smart way to catch and control malicious DNS queries without cutting off all DNS traffic. Blocking all outbound DNS (C) seems effective but would break normal network functions since systems rely on DNS to work properly. Sinkholing lets you redirect suspicious queries to a controlled environment, so you’re not completely shutting down DNS but still stopping exfiltration attempts. It’s more practical in a real-world setup where you can't just block everything.

Maybe C too, since if you don’t get who manages what, access controls get messed up.

C seems plausible too since misconfiguring access controls directly shows a lack of understanding about who’s responsible for what in the cloud setup. It’s a clear mistake from misunderstanding the shared responsibility.

B. While unauthorized changes (D) and installing unapproved software (A) are valid concerns, the key issue is that local admin rights provide a powerful foothold for attackers if compromised. Limiting those users reduces the risk that an attacker can easily escalate privileges and control the whole endpoint, which is a much bigger problem than just accidental user errors or extra admin overhead (C).

D imo, unauthorized changes can cause serious system instability or security gaps. While B is about external threats, preventing internal damage from careless or malicious insiders is just as crucial.

C imo, message-oriented middleware is more language-agnostic and flexible than RPC or object-oriented.

D/B? Object-oriented middleware like CORBA is designed for cross-language interaction using standard interfaces, but remote procedure call middleware also allows different languages to invoke each other's functions remotely. Both fit well depending on the setup.

D/B? A nation-state is clearly the attacker, but since it’s causing financial damage, that’s a kind of risk too. Still, threat actor fits better since it’s the entity doing the harm directly.

D for sure; the nation-state is the actual attacker, not the method or weakness.

Maybe C again. Operational tech usually involves lots of legacy gear that’s not just old but also complicated to maintain or upgrade. That mix makes it more prone to bugs and exploits compared to just old Ethernet or wireless devices. Plus, mainframe tech is old but usually well-locked down and managed tightly. So the age and complexity combo really points to operational technology being the weakest link here.

This feels like it’s about tech that’s both old and complex, so I’d say C since operational tech tends to be legacy systems that are tough to patch. C.

A. I think business resilience is the endgame because all the governance efforts should enable the business to keep running under cyber threats. The other options seem more like steps toward that goal.

A imo, business resilience feels like the ultimate goal since it means the company can withstand and recover from cyber threats, keeping things running no matter what happens. Value and risk are part of that bigger picture.

Option B seems right since using a service provider VPN often means you can’t monitor traffic closely, creating blind spots in user behavior that are tough to manage directly.

B/D? DoS attacks are pretty common with VPN endpoints since they’re exposed to the internet. Still, the biggest direct risk from a provider VPN feels like losing sight of user actions, so B sticks out more.

B tbh, libraries are just collections of pre-written code that apps use, so they don’t manage resources or enforce security. The question is about the core part handling hardware and policies, which rules out B, C, and D pretty quickly. The kernel is the only one that fits that description perfectly since it’s always running at a low level controlling everything behind the scenes.

D imo, the shell’s more about user interaction, not managing hardware or security. Libraries and applications definitely don’t handle that core role either. The kernel is the only one that fits since it’s responsible for resource management and security at the lowest level.

Maybe D too, since RDP directly exposes control of a system, making it a prime target for brute-force attacks. Unlike DNS or FTP, it’s not just data exposure but full remote control that’s risky here.

Maybe A makes the most sense here since SMB isn’t really designed for exposure to the internet, unlike FTP or DNS. It’s a common target for ransomware and often overlooked in firewall configs.

D vs A? Man-in-the-middle won’t alter internal logs, supply chain might leave subtle signs.

D Man-in-the-middle can be invisible since it intercepts data without altering systems.
