Option B
Synchronous replication modes of replication requires a very low latency network connection and ensures data remains in synch with zero data loss in the event of a failure at the source site
<u>Explanation:</u>
Synchronous replication, information is replicated to a subsequent remote place at the identical period as fresh information is implying generated or renewed in the original datacenter. Actually, both master and target roots endure effectively synchronized, which is vital for triumphant crash restoration.
In the circumstances of synchronous replication, this indicates that the write is deemed ended barely when both local and isolated warehouses approve its fulfillment. Therefore, nullity data failure is assured, but the overall execution is regulated down.
Which Internet security risk is associated with dumpster diving? Identity theft. Identity theft is associated with dumpster diving because it involves taking something from someone else. In this case, instead of looking through a dumpster to get items that were someone elses, they are taking their identity and using it for their own purposes. So identity theft and dumpster diving relate when used in this context.
Answer:
Door locks
Light switches
Security cameras
Thermostat
Explanation:
IoT is internet of things that means network of different things that are interconnected through internet and make the decision with the help of Electronic sensors. The sensor sense the data from environment at different times and send this to the cloud (that may be the server). On the basis of this data different devices such as door looks, light switches, security cameras and thermostat take decisions with the help of controllers and change their current state.
<u>For Example</u>
In case of door look, there may be sensor that is sensing the finger prints of the user and after recognizing the person the door will be unlock. If unauthenticated user will try to open the lock a message has been sent to concerned. The training data of the the authorized persons is saved on the cloud, whenever someone tries to access, the data from sensor and cloud send to controller for making comparison and decision. So we can say that Door lock can be controlled IoT.
In case of light switches, there are few sensor available to sense the intensity of life. Different training values of that sensors are stored on the cloud. Whenever these sensors sense the light intensity, they send the data to the cloud contentiously, whenever the data match with darkness intensity, a signal has been send from controller to the switch to ON the lights.
Same as in cameras and Thermostat both are sending data to the cloud and controller. With the help of different image processing techniques and sensor camera will take the decision related to face recognition. Thermostat devices are also on and off by variation of temperature.
It’s a lot of reading sorry can’t help you but try your best too
It won't let me send the answer. It says incorrect answer even though it's not but refer to these notes at the top.
