You work as a senior administrator at Contoso.com. The Contoso.com network consists of a single domain named Contoso.com. All servers on the Contoso.com network have Windows Server 2012 R2 installed.
You are running a training exercise for junior administrators. You are currently discussing the use of Non-Uniform Memory Architecture (NUMA).
Which of the following is TRUE with regards to Non-Uniform Memory Architecture (NUMA)? (Choose two.)
A. It is a computer architecture used in multiprocessor systems.
B. It is a computer architecture used in single processor systems.
C. It allows a processor to access local memory faster than it can access remote memory.
D. It allows a processor to access remote memory faster than it can access local memory.
Correct Answer: AC
Explanation/Reference:
Explanation:
NUMA is a hardware design feature that divides CPUs and memory in a physical server into NUMA nodes.
You get the best performance when a process uses memory and CPU from within the same NUMA node. de is full, then it’ll get memory from When a process requires more memory, but the current NUMA no another NUMA node and that comes at a performance cost to that process, and possibly all other processes on that physical server. And that’s why virtualization engineers need to be aware of this. In Hyper-V we have Dynamic Memory.
Non-Uniform Memory Access or Non-Uniform Memory Architecture (NUMA) is a computer memory design used in multiprocessors, where the memory access time depends on the memory location relative to a processor. Under ccNUMA, a processor can access its own local memory faster than non-local memory, that is, memory local to another processor or memory shared between processors. NUMA architectures logically follow in scaling from symmetric multiprocessing
(SMP) architectures.
