Answer:

Option B is the correct option.

Explanation:

When using SQS the user request to separate a query. The specification specifies that updates on the list may have been transmitted multiple times, but it must be transmitted throughout the sequence in which they appeared, and therefore should require secure, repetitive queue polling.

TLS is not generally compatible with SSL because:__________. 1. SSL is proprietary while TLS is open 2. SSL can interact with it
kodGreya [7K]

Answer:

2. SSL can interact with its earlier versions which is a vulnerability

Explanation:

TLS (Transport Layer Security) and SSL (Secure Sockets Layer) are both used for providing data authentication and encryption between networking devices  (such as servers, PCs and applications) operating over a network. The iterations of SSL were versions 1.0, 2.0 and 3.0. But then, all these iterations had security issues and so TLS 1.0 was released to improve on those security flaws. And seeing that SSL can interact with its earlier versions which are all vulnerable, downgrading TLS to SSL for compatibility sake will abuse the essence of TLS in the first place.
