◍ A construction company produces furnished pre-fabricated manufactured
homes. The production manager has discovered the following challenges
within one of the facilities:• Production qualities are low and only a small
number of homes are built efficiently.• The facility space allows for low
handling of materials.• There is limited space available for employees to
operate.Which hybrid layout should be used to address the company’s
needs?Group technologyProcess performance metricsManufacturing
technologyStatistical reduction control.
Answer: Group technology

preferred for a specific type of traffic.A single gateway exiting a location is
preferred for all traffic.A single gateway exiting a location is preferred for
only traffic marked for null 0.A single gateway exiting a location is
preferred for traffic with double encryption..
Answer: A single gateway exiting a location is preferred for a specific type
of traffic.
◍ What does clustering defend against?Single point of failure in a
controllerLateral movement of an attackerBlurred trusted domain
boundariesInternal network attacks.
Answer: Single point of failure in a controller
◍ Deming Prize.
Answer: Prize established by the Japanese and awarded annually to firms
that distinguish themselves with quality management programs.
◍ Capacity Requirements Planning (CRP).
Answer: Uses data from MRP to calculate workload for critical work centers
