Procedures in programming are considered an abstraction because they allow the programmer to create a reusable block of code that can be called multiple times throughout the program without having to repeat the same code.

This abstraction allows the program to be more organized, modular, and easier to read and maintain. By breaking down a program into smaller procedures, it becomes easier to understand the overall logic of the program and to identify and fix errors or bugs. Procedures can also be thought of as a black box, where the implementation details are hidden and only the input and output parameters are visible, allowing for further abstraction and separation of concerns in the program.

The performance of shared memory multiprocessors is influenced by various factors, but two of the most dominant ones are memory contention and cache coherence.

Memory contention occurs when multiple processors try to access the same memory location simultaneously, leading to delays and increased access time. This can lead to decreased performance, as it causes the processors to wait for access to the memory. Cache coherence, on the other hand, refers to the process of maintaining consistency between the caches of different processors, so that all processors have a consistent view of the shared memory. This process can also lead to delays and increased access time, as the processors must communicate and coordinate to ensure that the cache coherence is maintained.

The most likely cause for the specific traffic not being logged is  HTTP traffic is not forwarding to HTTPS to decrypt. option C

Here's an explanation supporting this choice:

The user agent client not being compatible with the WAF (option A) would not directly result in specific traffic not being logged or the lack of visibility. Incompatibility issues might affect how the WAF interacts with the client, but it would not cause traffic to go unnoticed or unlogged.

An expired certificate on the WAF (option B) might cause issues with secure connections, but it would not necessarily lead to the specific traffic not being logged or the lack of visibility. Expired certificates usually result in warning messages but should not prevent logging or visibility.

HTTP traffic not forwarding to HTTPS, is a common reason for traffic not being logged or visible. If the web server is configured to only accept HTTP traffic and does not redirect it to HTTPS, the WAF may not be able to inspect and log the encrypted traffic. The WAF is designed to analyze and protect traffic that is decrypted after being received from the client.

Old, vulnerable cipher suites being used  could potentially pose security risks, but it would not directly lead to specific traffic not being logged or the lack of visibility. Cipher suites determine the encryption algorithms used for secure connections and do not typically impact logging or visibility.

In conclusion, the most likely cause for the specific traffic not being logged and the lack of visibility from the WAF for the web application is HTTP traffic not forwarding to HTTPS to decrypt, as this prevents the WAF from inspecting the encrypted traffic. SO Option C is correct.
