Total questions: 12
Worksheet time: 6mins
Which part of a fiber optic is the waveguide, providing the transmission path for the light?
core
cladding
buffer
outer jacket
Fiber optic cables are susceptible to which of the following?
EMI only
attenuation only
both EMI and attenuation
neither EMI nor attenuation
Which type of fiber optic cabling is primarily used for long haul communications or in data centers?
SMF
MMF
both SMF and MMF
It depends on the connector used
OM1 & OM2 fiber has a lower data rate than OM3 & OM4 fiber because
it uses an LED as a light source instead of a laser
the connector it uses cannot handle data rates above 1 Gbps
the shielding in the cable is not strong enough to block outside light sources
the wavelength of the light source makes it more susceptible to EMI
The earliest type of fiber optic connector, a bayonet-stype originally developed for the Department of Defense is
ST
LC
SC
MPO
The small form-factor connector commonly used for 10/40 GbE over a single fiber optic cable is
ST
LC
SC
MPO
The fiber connector that allows for bundling 12 or more SMF or MMF cable strands into one connector, providing data rates up to 400 Gbps, is
SC
ST
LC
MPO
A serial bus topology uses which type of cable?
UTP Ethernet
Coaxial Cable
Fiber Optic Cable
Which of the following is NOT a characteristic of a collision domain?
all network nodes share the same media
only one node can transmit at a time
ring and bus topologies have one collision domain
nodes transmit and receive over different connections
TRUE or FALSE: A hub does not process the data it receives; it simply repeats it out of every other interface.
TRUE
FALSE
A hub operates physically in a ______ topology but logically as a ______ topology.
star, ring

TRUE or FALSE: All nodes on a hub are part of the same collision domain.
TRUE
FALSE
