Abroadcast IP addressis used tosend a message to all deviceson a specific IP subnet. This address is thehighest address in the subnet(i.e., all host bits set to 1).
Example: In 192.168.1.0/24 → broadcast is 192.168.1.255.
It is used for purposes like ARP requests or DHCP discovery.
Option A is correct– refers to all hosts in a subnet.
Option Brefers tomulticast, not broadcast.
Option Cmight refer toanycast, which is different.
Option Ddescribes aunicastaddress.

Question # 15
Which of the following Nokia 7750 SR components is NOT part of the data plane?
TheNokia 7750 SR architectureseparates its operations intocontrol planeanddata planefunctions.
TheData Planeincludes hardware components responsible for forwarding traffic at line rate. These components include:
MDA (Media Dependent Adapter)– interfaces with physical media.
IOM (Input/Output Module)– performs high-speed packet forwarding and processing.
XMA (eXpandable Media Adapter)– extends port capacity and media support.
TheControl Planeincludes theCPM (Control Processor Module), which is responsible for running routing protocols, managing configuration, system operations, and other control-related functions. The CPM does not participate in data forwarding and is thusnot part of the data plane.
