Questions 5

A banking company is developing a new set of APIs for its online business. One of the critical API's is a master lookup API which is a system API. This master lookup API uses persistent object store. This API will be used by all other APIs to provide master lookup data.

Master lookup API is deployed on two cloudhub workers of 0.1 vCore each because there is a lot of master data to be cached. Master lookup data is stored as a key value pair. The cache gets refreshed if they key is not found in the cache.

Doing performance testing it was observed that the Master lookup API has a higher response time due to database queries execution to fetch the master lookup data.

Due to this performance issue, go-live of the online business is on hold which could cause potential financial loss to Bank.

As an integration architect, which of the below option you would suggest to resolve performance issue?

Options:

A.

Implement HTTP caching policy for all GET endpoints for the master lookup API and implement locking to synchronize access to object store

B.

Upgrade vCore size from 0.1 vCore to 0,2 vCore

C.

Implement HTTP caching policy for all GET endpoints for master lookup API

D.

Add an additional Cloudhub worker to provide additional capacity

Questions 13

A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity. The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms. If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

Options:

A.

Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

B.

Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

C.

Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

D.

No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API

Questions 22

An organization is designing an integration Mule application to process orders by submitting them to a back-end system for offline processing. Each order will be received by the Mule application through an HTTPS POST and must be acknowledged immediately. Once acknowledged, the order will be submitted to a back-end system. Orders that cannot be successfully submitted due to rejections from the back-end system will need to be processed manually (outside the back-end system).

The Mule application will be deployed to a customer-hosted runtime and is able to use an existing ActiveMQ broker if needed. The ActiveMQ broker is located inside the organization’s firewall. The back-end system has a track record of unreliability due to both minor network connectivity issues and longer outages.
