FC0-U61 · Question #898

Which of the following is the best reason to implement a software token instead of a hardware token?

The correct answer is C. A software token is more cost efficient than a hardware token.. The primary advantage of software tokens over hardware tokens is their significant cost efficiency, as they typically leverage existing devices and do not require physical manufacturing and distribution.

Which of the following is the best reason to implement a software token instead of a hardware token?

Options

  • AA software token can be set to a permanent number that never changes.
  • BA software token can be encrypted.
  • CA software token is more cost efficient than a hardware token.

Why each option

The primary advantage of software tokens over hardware tokens is their significant cost efficiency, as they typically leverage existing devices and do not require physical manufacturing and distribution.

AA software token can be set to a permanent number that never changes.

Both hardware and software tokens can generate permanent or changing numbers, depending on the specific implementation (e.g., static password vs. OTP), so this is not a distinguishing best reason for software.

BA software token can be encrypted.

While software tokens can be encrypted, hardware tokens are also designed with security features, including tamper resistance and secure storage, making this not a unique 'best reason' for software tokens.

CA software token is more cost efficient than a hardware token.Correct

Software tokens are generally more cost-efficient because they often run on existing devices (like smartphones) and don't require the manufacturing, shipping, and replacement costs associated with physical hardware tokens.

DA software token cannot be lost.

A software token can certainly be lost if the device it's installed on (e.g., a smartphone) is lost or stolen.
