What assurance does the content authenticity feature of CAS provide?
- A. Stored content is protected against erasure
- B. Storing only one instance of content
- C. There are always multiple copies
- D. Validity of stored content
Answer: D
Explanation:
Explanation
CAS assures the genuineness of stored content. This is achieved by generating a unique content address for each object and validating the content address for stored objects at regular intervals. Content authenticity is assured because the address assigned to each object is as unique as a fingerprint. Every time an object is read, CAS uses a hashing algorithm to recalculate the object's content address as a validation step and compares the result to its original content address. If the object fails validation, CAS rebuilds the object using a mirror or parity protection scheme.
