How would the guard know every individual and their access rights? The access control vestibule (AKA Mantrap) seems to be more appropriate to me.

I chose escort as it mentions the tech is already in the DC. In my experience a mantrap is usually located near the entrance, the question seems to suggest he is already in the DC and walking around. It's a poorly worded question IMO though. When they talk about an area are they referring to say a few rows where racks are in a DC or are the talking about a room? If its a room then mantrap, if its the fortmer then escort.

C is correct. Contact at [email protected] to get full version.

Mantraps are ONLY at the entrance to the Data Center. I've NEVER in my 25 years in IT seen a mantrap WITHIN a Data Center but only at the entrance. Look at this definition of a Security Vestibuile: Access control vestibules, also known as security or mantrap vestibules, are a highly effective means of hardening commercial security. These enclosed entryways are designed to restrict and monitor access to a building by allowing only one person to enter at a time, typically through a series of interlocking doors. The function is not to restrict users WITHIN the data center. Its used to stop more than one person from going into a datacenter at one time or to prevent someone from stealing something. Its NOT to prevent someone from going into OTHER sections of the data center. The correct answer has to be D not C because thats not the function of MANTRAPS!!!

C. Implement access control vestibules. Access control vestibules, also known as mantraps or airlocks, are physical security measures designed to control access to a secured area. They typically consist of a small enclosed space with two sets of interlocking doors. To gain access to the secured area, an individual must first enter the vestibule, wait for the outer door to close and be authorized, and then the inner door will open. This helps prevent unauthorized individuals from entering restricted areas by providing an additional layer of security.

The access control vestibule

It all depends on the Data Center because I personally worked as an Engineer, and we had to notify the site ahead of time that we were coming onsite. At that time, they would issue us a badge that would give access to the room we needed to enter to work on a server. At other sites they have someone who would escort you to the room you suppose to enter, and they have cameras everywhere to monitor if you are wondering the halls. So the Mantrap in my opinion would be the best choice. The Mantrap makes sure you can only enter the room they give you access to.

Not sure why it says answer is B. That may not prevent it in the future. A mantrap would

Only C and D actually could prevent access, and of the two, C seems a lot more plausible than having an escort for each visitor.

Former telco guy here..in the past I used to frequently visit our colo and was always escorted by a DC staff member and made sure I went into "OUR" cage where our equipment resided. However, since Comptia is in love with "mantraps" and "vestibules", I am going with that..horrible question

Question, states techie entered (just strolling along) into a restricted area without "authorization" there's only one answer that has access control in it. I'm going with Vestibules... you can have one without access control but this one is top'o the line probably has a cute little beep when you tap your RFID on it and it validates access... or not (for this person anyways)

No clue what the correct answer is but I'll go with "Implement access control vestibules." It's probably the closest to what CompTIA is thinking: "access control"

Honestly our perspective,D is the right answer believe me I know I work in IT and based on certain projects to go in the Data Center/Classified Comm room visitors need to sign a sheet and be escorted sometimes set appointment to even get escorted. CompTIA is tricky so we need to go base on what they think and honestly just an escort I highly doubt Comptia would have that as there answer I’ll go with C

He is not a visitor he is a technician who did not have access...."Access" >'keyword'<

You could make an argument for either Implement access control vestibules OR Enforce escorts to monitor all visitors But no way would cameras "prevent" such a thing from recurring. Bad question.

Definitely not B We have visitor badges that state escort required for just such a scenario. The AC Vestibule would not control un/authorized access to the DC unless we're supposed to assume that directly following the AC Vestibule is the DC.

honestly, i am confused, whats the correct answer according to comptia guys ?
