Question-7: A patient's paper chart has been replaced with a digital document known as an electronic health record (EHR). Electronic health records (EHRs) are real-time records that are focused on the patient and make information instantaneously and securely accessible to authorized users. Please see the case study on EHR Healthcare for more information on this topic. You are a member of the development team for the EHR customer portal. Recently, your team completed the migration of the application serving as the customer interface to Google Cloud. As a result of the increasing strain on the application servers, the programme is now recording a significant number of timeout problems. You just just added Pub/Sub to the architecture of the application, however the application is not recording any Pub/Sub publishing failures. You want to decrease the amount of time it takes to publish. What action should you take?
A. Raise the retry threshold for the Pub/Sub Total Timeout setting.
B. Make the switch from the pull model used by Pub/Sub subscribers to the push model.
C. Disable the batching of Pub/Sub messages.
D. Create a backup Pub/Sub message queue.

: 3 Explanation: The delay of individual messages increases when batching is used. It is recommended that batching be disabled in order to reduce latency. The latency of individual messages increases as a result of batch processing because the messages are stored in a queue in memory until their corresponding batch is completed and ready to be transmitted over the network. It is recommended that batching be disabled in order to reduce latency. https://cloud.google.com/pubsub/docs/publisher?hl=en# batching Incorrect answer, Option-1. The application timed out due to the delay of the publisher; this had nothing to do with the timeout retry function associated with the publish request. Option-4 does not make sense at all. Option-2 focuses on the receiver rather than the publisher. However, neither the question nor the scenario state that they activated the Pub/Sub batching feature. Even though increasing the total timeout would help reduce the number of timeout errors, keep in mind that in this particular case, the load on the server has increased, and as a result, we are receiving an excessive number of messages; therefore, we need to decrease the latency. It is talking about timeout, so answer Option-3 is incorrect; it is not about latency. I believe that increasing the total timeout retry value will be beneficial, so the correct answer is Option-1 The length of time after which a client library will cease retrying publish requests after they reach the total timeout.
