I think both but in Jawaroski mock test ans. is Security
From John's notes:
Manageability
Manageability refers to the ability to manage a system to ensure the health of the system.
A single tier or monolithic app would be more manageable from a management perspective than a multi-tier system,
but this must be weighed against the possibility of a change rippling through a monolithic app. From Alex Chaffee�s article:
One-tier architecture has a huge advantage: simplicity. One-tier applications don't need to handle any network protocols, so their code is simpler. Such code also benefits from being part of an independent operation. It doesn't need to guarantee synchronization with faraway data, nor does it need exception-handling routines to deal with network failure,
bogus data from a server, or a server running different versions of a protocol or program.
Moreover, a one-tier application can have a major performance advantage. The user's requests don't need to cross the network, wait their turn at the server, and then return. This has the added effect of not weighing down your network with extra traffic, and not weighing down your server with extra work.
In jaworski�s question, he is asking the
potential advantage of one-tier, so security is a better answer.
Hope this helps.
