[All CDPSE Questions]

Transport Layer Security (TLS) provides data integrity through:

Acalculation of message digests.

Buse of File Transfer Protocol (FTP).

Casymmetric encryption of data sets.

Dexchange of digital certificates.

Show Suggested Answer

Suggested Answer: A

Transport Layer Security (TLS) is a protocol that provides secure communication over the internet by encrypting and authenticating data. TLS provides data integrity through the calculation of message digests, which are cryptographic hashes that summarize the content and structure of a message. The sender and the receiver of a message can compare the message digests to verify that the message has not been altered or corrupted during transmission. TLS also uses digital certificates, asymmetric encryption, and symmetric encryption to provide confidentiality and authentication, but these are not directly related to data integrity.

Digital certificates? I thought they were for authentication, not integrity!

C sounds right too, but A is definitely the main one.

Wait, isn't B relevant for file transfers only?

A is correct! Message digests ensure data integrity.

Digital certificates are important for authentication, but I don't think they directly provide data integrity like message digests do.

I don't recall FTP being relevant to TLS at all, so I doubt option B is correct.

I remember practicing a question about TLS and message authentication codes, which might relate to option A.

I think data integrity in TLS has something to do with message digests, but I'm not completely sure if that's the only method used.

I remember learning about TLS in class, but I'm drawing a blank on the specifics right now. I'll have to eliminate the options that I know are wrong, then make an educated guess on the rest.

Hmm, I'm a little unsure about this one. I know TLS is related to data integrity, but I'm not sure if the options fully capture how it achieves that. I'll have to think this through carefully.

This one seems pretty straightforward. I'm pretty confident the answer is A - calculation of message digests.

Okay, let's see. TLS uses cryptographic techniques to ensure data integrity, so I'm guessing the answer has to do with that. I'm leaning towards A, but I'll double-check my notes just to be sure.

I think I've got a good handle on this. The key is understanding the restrictions on cryptography in the US export laws, and how the Oracle Solaris 11 Cryptographic Framework accommodates those restrictions.

Okay, let me think this through. We want to restrict the replication bandwidth on the destination cluster, so I believe the correct answer is to use OnCommand System Manager on the destination cluster to create a QoS policy.
