Module 1 - Networking Fundamentals explores key networking concepts, focusing on the OSI Model, data transmission, and networking standards like IEEE 802.11g and Power over Ethernet. This quiz assesses understanding of network layers, data rates, and switching functions, essential for students and professionals in IT.

Rate this question:
Channel 12 should be disabled because it is affected in most parts of the world by 802.11h restrictions.
In certain configuration setups, the WLAN system dynamically enables or disables supported channels whenever co-channel interference occurs and more channels are needed.
Channel 12 is not part of the 802.11b/g-supported bands and should never be used in indoor deployments.
Channel 12 is not part of the unlicensed OFDM frequency range. An operator’s license is required to use this channel.
Channel 12 is not supported by all 802.11b/g client devices. Enabling channel 12 when some clients don’t support it may create a coverage gap for those clients.
Rate this question:
VLANs establish broadcast domains in switched networks
VLANs utilize packet filtering to enhance network security
VLANs provide a method of conserving IP addresses in large networks
VLANs provide a low-latency internetworking alternative to routed networks
VLANs allow access to network services based on department, not physical location
VLANs can greatly simplify adding, moving, or changing hosts on the network
Rate this question:
A hardware device that connects dissimilar physical networks
A network host that reads the source and destination addresses in the packet header and makes decisions about where to forward the packet
A network host that can forward LAN-based email messages onto the Internet, after repackaging them into the SMTP format
A software system that can translate one application protocol in to another application protocol

The same data is broadcast simultaneeously to every machine on the network
Individual host machines decide whether they wish to participate in a multicast group
Multicast traffic is only generated on request from host machines
Multicast traffic creates maximum traffic through every port on the network
Multicast traffic creates efficiency and saves bandwidth on the network by only transmitting data when and where it is requested
Multicast allows multiple computers to connect to the same port on a switch
