Exam SY0-701 topic 1 question 241 discussion

I would go with B. Here is the reasoning, for an immediate response to a compromised device, remote swipe may be the best option. But the question asks "What is the best solution to increase mobile data security on all employee's devices?" Implementing FDE across all company devices raises the baseline security for the entire organization ensuring that data on all devices is protected. With compromised credentials a remote swipe might even be too late, if you don't find out fast enough that the device has been stolen.

B. Full disk encryption (FDE). The question was not asking about the single phone that was stolen (in which case a remote wipe may work after the fact); rather, it asks for "the best solution to increase mobile data security on all employees' company mobile devices".

Full disk encryption means nothing once the attacker logs in. Remote wipe is the most appropriate response.

The answer is B. The question is what should they do to increase the security o n employees phone. The question is not saying what should they do. with the stolen phone!!

encryption means nothing if they are in using a username and password - remote wipe is need to protect the organization

The condition is "solution to increase mobile data security on all employees' company mobile devices", and that solution is 'B' - FDE

Even if a threat actor gains access to the device, they would still need to bypass additional authentication mechanisms to access the data within the container. IT administrators can enforce security policies within the container, such as restricting copy/paste functions, disabling screenshots, and requiring strong authentication.

To those picking FDE because you wouldn't wipe all users' phones, this is missing the boat. You are implementing a remote wipe solution, NOT wiping everyones' phones. Given the example provided, I can't see anything but C being correct here.

B makes sense

It says "on ALL employees devices" You aren't going to full wipe every employees mobile devices when only one has been infiltrated. Full disk encryption will increase security going forward.

I'm gonna keep it short here because Ty already explained it perfectly, but it's not B. "If someone steals a phone AND has your credentials, the device has already been pwned" and remote wiping the stolen device is pretty much your only option. You just have to hope it gets reported and the security team gets to it fast enough. There are other measures they could have taken beforehand that would make the attacker having the username and password less devastating. This would be a big "oops" moment, all you can do is damage control.

for some reason I thought FDE only worked with Laptops, well in this case I would choose FDE too

Key word here is on all employees company mobile phones, so why would you wipe everyone`s data when only one device was stolen.

'Data Protection: Full disk encryption (FDE) encrypts all data stored on a mobile device, ensuring that even if the device is lost or stolen, the data remains inaccessible without the proper authentication key (e.g., a password or PIN). This is crucial for protecting sensitive company information from unauthorized access' The answer is remote wipe because the device has already been accessed using the user name and password'

C. Remote Wipe Anyone who understands MDM would be able to answer this immediately. Phones are already encrypted - whether it's Android or Apple - otherwise your phone would be a disastrously vulnerable computer. If someone steals a phone AND has your credentials, the device has already been pwned and you have no option but to remote wipe it and hopefully stop them from accessing any further info.

because he talk about the future so B is correct

Key Word: "increase mobile data security"
