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 NonUniform 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.
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.
