What is the Institute of Electrical and Electronics Engineers (IEEE) specification for Spanning Tree Protocol
(STP)?

A.
802.1d

B.
802.1q

C.
802.3u

D.
802.3z

Explanation:
The IEEE specification for STP is 802.1d. STP uses the spanning-tree algorithm to find and prevent loops in
redundant network topologies. This helps mitigate broadcast storms, multiple copies of frames, and Media
Access Control (MAC) address database inconsistencies.
The IEEE committee developed the 802.1 series of specifications for bridging. The IEEE 802.1q specification is
for Virtual LAN (VLAN) trunking. Per this specification, a 4-byte 802.q header, which contains the Priority and
VLAN ID fields, is inserted in the middle of the original Ethernet header.
802.3 is the IEEE committee specification that defines the Ethernet group. Ethernet is a LAN protocol that
specifies physical layer and MAC sublayer media access. IEEE 802.3 uses carrier sense multiple access
collision detect (CSMA/CD) to provide access for many devices on the same network. 802.3u is the IEEE
specification for Fast Ethernet. 802.3z is the IEEE specification for Gigabit Ethernet.
