An engineer learns a new security threat mitigation technique. The technique maps an IP address to a non-existent host, and is useful in stopping denial of service attacks. Traffic heading to these IPs can be captured for analysis or discarded. Considering the given strategies, which does this technique relate to? Select all that apply. A. Black hole
B. Sinkhole
C. Forward proxying
D. Reverse proxying

A. In network architecture, a black hole drops traffic before it reaches its intended destination, and without alerting the source. A simple example is traffic sent to an IP address that an admin mapped to a non-existent host.
B. A sinkhole is similar to configuring a black hole, and often used interchangeably. With sinkholing however, an admin usually retains some ability to analyze and forward the captured traffic.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
