Solid certification book for the CAS-003 CASP+ exam. I just passed my exam this past Monday! To be clear, though, this book alone will NOT get you to pass the CASP+.
This test is an absolute beast. I did practice tests, read cert books/cert reading material, and attended an instructor-led training. You really have to know a wide variety of areas in infosec to pass this. I finally understand why it is recommended to have 10 years' industry experience for this one..!
