Which selection is a reason why IGMP snooping should be configured on a switched network?

• A.IGMP snooping verifies the source IP address of every IPv4 packet to ensure that it hasn't been originated from a port different than its return path.
• B.IGMP snooping populates the snooping table with the results of DHCP requests and can be used by Dynamic ARP Inspection to block IP spoofing attacks at Layer-2.
• C.IGMP snooping allows a Layer-2 switch to limit the transmission of multicast frames to only the ports that have members of the relevant IGMP group.
• D.IGMP snooping is used to filter ping requests and results to avoid overflowing the MAC address table of the switch.

Profinet has been disabled on a Cisco Industrial Ethernet switch, which CLI commands correctly enable ProfiNET on VLAN 10?

• A.switch(config)#profinet
  switch(config)#vlan 10
  switch(config-vlan)#profinet
• B.switch#enable profinet
  switch(config)#vlan 10
  switch(config-vlan)#profinet
• C.switch#enable profinet
  switch(config)#profinet vlan 10
• D.switch(config)#profinet
  switch(config)#profinet vlan 10

Exhibit:

Refer to the exhibit. CCNA.com has the industrial network shown in the exhibit. All switches are configured as layer 2 switches and are using VLAN 1 as their management VLAN.
Each VLAN 1 interface has been assigned the correct IP address. What is the purpose of assigning a default gateway to SW-C switch?

• A.allows connectivity between the VLAN 1 interface on SW-C and other devices in the network.
• B.allows the switch to pass traffic between Host A and Host B
• C.allows connectivity between Host A and other devices in the network.
• D.allows connectivity between Host B and other devices in the network.

Which is an issue with running CIP Motion on a REP network and identifies an alternate resiliency protocol that works for CIP Motion?

• A.REP convergence is not fast enough. RPVST+ is a suitable resiliency protocol for CIP motion.
• B.CIP Motion requires a star topology which is not supported by REP. RPVST+ is a suitable resiliency protocol for CIP motion.
• C.CIP Motion requires a star topology which is not supported by REP. DLR is a suitable resiliency protocol for CIP motion.
• D.REP convergence is not fast enough. DLR is a suitable resiliency protocol for CIP motion.

A shutdown in the cookie cutter machine was traced to a broken network cable. What are two reasons that explain why using DLR is an appropriate choice for network resiliency?
(Choose two)

• A.DLR is designed for single network operation at the machine level
• B.Moving to a linear topology will reduce the number of cables and so reduce risk of cable failure
• C.DLR is the only resiliency technology that is supported by CIP Safety
• D.Layer 2 resiliency protocols like REP and RSTP do not have a fast enough convergence time for motion control
• E.Half of the network traffic goes clockwise on the ring and the other half counter- clockwise, reducing by 50% the impact of cable failure
