Suggested Answer:D🗳️
Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources.
The last sentence:
Shielded CAT5e cable is generally referred to as STP CAT5e or Shielded Twisted Pair CAT5e. This term, however, is used to refer to many different styles of shielding. The most common type of shielding uses what is called a screen. This screen is a metal covering that goes around the entire set of 8 wires found in CAT5e cable. This can be done by a single solid foil wrap around the wires, braided strands of cable wrapped around all the wires, or a combination of the two. This type of cabling is very effective at blocking any EMI that could cause problems in most installations.

Twisting reduces crosstalk, yes, but it also reduces EMI and RFI. Change the STP to UTP and twisting would be the only correct answer, but as written both shielding and twisting are correct. Badly worded question, but from research it seems that this question is looking for the "twisting" answer on the test, regardless of what is actually correct.
A resposta certa no meu ver é blindagem, pelo tipo de cabo no enunciado (FTP (Foiled Twisted Pair)).
São cabos os que utilizam uma blindagem mais simples: de fina folha de aço ou de liga de alumínio, elementos que envolvem todos os pares do cabo, protegendo-os contra interferências externas.
"A metal shield protects wires from radio and electromagnetic interference". The shielding basically blocks interference and cross talk (well, reduces it). So, it SHOULD be shielding.
This question is very conflicting. Needs to be fixed
