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

• A.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.
• B.IGMP snooping is used to filter ping requests and results to avoid overflowing the MAC address table of the switch.
• C.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.
• D.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.

Why is SSH preferred over Telnet as a method of accessing a network device to alter or view the configuration?

• A.SSH requires fewer network resources and no additional configuration.
• B.Telnet encrypts only the login information, not the entire transmission.
• C.Telnet is more difficult to use and configure than SSH.
• D.SSH encrypts the login and session information.

A ProfiNET management system operator is unable to see diagnostic information for a
Cisco Industrial Ethernet switch that has been added to a SIMATIC management station.
Based on the provided CLI output, which statement is correct?
switch# show profinet status
State : Enabled
Vlan : 201
Id : IE2000-Switch
Connected : Yes
ReductRatio : 128
GSD version : Mis-match

• A.The Reduction Ration has been set too low
• B.LLDP has been disabled on this switch
• C.The GSD file version on the switch does not match the GSD file version on the management station
• D.The assigned ProfiNET VLAN is not valid and should be less than 100

Refer to the exhibit.

You are required to implement traffic segmentation in the network. See the table for relevant device details:
L2SW4, L2SW5, and L2SW6 are connected to L3SW1 with 802.1Q trunks with VLAN 191 and VLAN 398 allowed on the trunk.
You have the following information from L3SW1:
L3SW1# show run interfaces
interface Vlan1
no ip address
shutdown
!
interface Vlan2
ip address 10.2.2.2 255.255.255.248
!
interface Vlan191
ip address 10.10.27.126 255.255.255.192
!
interface Vlan200
ip address 10.20.20.1 255.255.255.248
!
interface Vlan398
ip address 10.15.153.1 255.255.255.0
L3SW1# show ip route

You are required to implement a configuration that will meet the following connectivity requirements:
* The Administrator's Station must have full access to PanelView
* PanelView should have limited access, based on specific TCP ports, to PLC#1 and I/O#1
* The Administrator's Station should have no access to PLC#1 and I/O#1
* PLC#1 and I/O#1 should be able to communicate with each other on any port
Which action will allow you to meet the connectivity requirements?

• A.Implement an ACL on Firewall1 to control the traffic flow between VLAN 191 and VLAN 398
• B.Put interface VLAN 191 and interface VLAN 398 into different Virtual Routing and Forwarding (VRF) instances on L3SW1
• C.No change is required, the traffic is already limited appropriately by the VLAN segmentation
• D.Deploy an inbound ACL on interface VLAN 191 to control the traffic from the Administrator's Station and PanelView to PLC#1 and I/O#1

Refer to the exhibit. The Robot Cell is in a bottling plant. This cell environment needs to consider high flex, EMI, and possible exposure to moisture. Which physical media components need to be considered to prevent network degradation or interruptions?

• A.Solid, unshielded commercial jacket wire, and M12 connectors
• B.Solid, shielded wire with commercial grade jacket, and commercial grade RJ45 connectors
• C.Stranded, shielded wire with an industrial jacket and M12 connectors
• D.Stranded, unshielded wire with an industrial jacket, and commercial grade RJ45 connectors
