Section: Cryptography
Explanation/Reference:
The Internet Security Glossary (RFC2828) defines an attribute certificate as a digital certificate that binds a set of descriptive data items, other than a public key, either directly to a subject name or to the identifier of another certificate that is a public-key certificate. A public-key certificate binds a subject name to a public key value, along with information needed to perform certain cryptographic functions. Other attributes of a subject, such as a security clearance, may be certified in a separate kind of digital certificate, called an attribute certificate. A subject may have multiple attribute certificates associated with its name or with each of its public-key certificates.

Section: Risk, Response and Recovery
Explanation
Explanation/Reference:
The keyword is ' MOST CRITICAL ' and the correct answer is ' Management Support ' as the management must be convinced of its necessity and that's why a business case must be made. The decision of how a company should recover from any disaster is purely a business decision and should be treated as so.
The other answers are incorrect because :
Security policy is incorrect as it is not the MOST CRITICAL piece.
Availability of backup information processing facilities is incorrect as this comes once the organization has BCP Plans in place and for a BCP Plan , management support must be there.
Staff training comes after the plans are in place with the support from management.

Explanation/Reference:
Remote Journaling is a technology to facilitate sending copies of the journal of transaction entries from a production system to a secondary system in realtime. The remote nature of such a connection is predicated upon having local journaling already established. Local journaling on the production side allows each change that ensues for a journal-eligible object e.g., database physical file, SQL table, data area, data queue, byte stream file residing within the IFS) to be recorded and logged. It's these local images that flow to the remote system. Once there, the journal entries serve a variety of purposes, from feeding a high availability software replay program or data warehouse to offering an offline, realtime vault of the most recent database changes.
