Which three options are needed to configure NAT on router GW so PC1 and PC2 will be able to ping 203.0.113.1? (Choose three)

What can be done to increase the security in depth in an industrial zone?

Which configuration enables an Industrial Ethernet switch to participate in PTP clock selection and sets the priority value that would break the tie between switches with matching default criteria to 50?

Refer to the exhibit.

The control system depicted in the exhibit uses VLAN 300 for all of its device ports and
PVST is enabled on each switch to switch connection. L2SW4 was inserted between
L2SW3 and L2SW5. Links FO2 and FO3 were added and FO1 was disconnected.
Prior to the installation of L2SW4, PanelView was able to communicate with PLC#1. After
the change, PLC#1 and PanelView are still able to communicate but neither PLC#1 or
PanelView are able to communicate with I/O #1.

Based on the output from the switch, what is preventing I/O#1 from communicating with
PLC#1 and PanelView?

Which command globally enables QoS on a Cisco Industrial Ethernet switch?

Refer to the exhibit.

All of the vlans listed in the routing table below are trunked using 802.1q and are active on all switches. PLC1, PLC2, and PLC3 each has IP address 192.168.0.1/24 and are
connected to ports configured for vlan 50. L2SW1, L2SW2, and L2SW3 are not using vlan
trunking for vlan 50.
L3SW1 has following routing table:
10.0.0.0/8 is variably subnetted, 12 subnets, 2 masks
C 10.3.138.0/23 is directly connected, Vlan307
C 10.3.136.0/23 is directly connected, Vlan306
C 10.15.153.0/24 is directly connected, Vlan398
C 10.3.142.0/23 is directly connected, Vlan309
C 10.3.140.0/23 is directly connected, Vlan308
C 10.3.186.0/23 is directly connected, Vlan293
C 10.15.154.0/24 is directly connected, Vlan399
C 10.3.184.0/23 is directly connected, Vlan292
C 10.3.190.0/23 is directly connected, Vlan295
C 10.3.188.0/23 is directly connected, Vlan294
C 10.3.182.0/23 is directly connected, Vlan291
C 10.3.180.0/23 is directly connected, Vlan290
PLC1, PLC2, and PLC3 cannot be reconfigured.

What can be done to be able to simultaneously communicate with PLC1, PLC2, and PLC3?

When troubleshooting a high packet loss condition in the network, the inspection area has
an assessed M.I.C.E. value of M=1, I=1, C=3 and E=1.
Which condition could be suspect?

Refer to the exhibit.

SW1, SW2 and virtual switch are connected in a loop. SW1 and SW2 are standard layer-2 switches.
Which loop prevention mechanism is best suited for use within this topology?

A cookie cutter machine requires 2 standard controllers and a safety controller. All of these controllers and machine level I/O have been placed on VLAN 104. The safety controller must monitor an emergency stop connected to an I/O adapter on an adjacent machine (VLAN 105).
Which packet type will be used?

Refer to the exhibit.

CIP Implicit messages from I/O#1 are being marked IP DSCP 47 by the endpoint and this
marking is trusted by L2SW4. L2SW4 is configured to map DSCP 47 to output queue 1
threshold 1. You have received feedback that some of these messages are not being
received. Executing the show mls interface GigabitEthernet statistics command on L2SW4
results in:
L2SW4# show mls interface GigabitEthernet 1/1 statistics
<output omitted>
output queues dropped:
queue: threshold1 threshold2 threshold3
queue 0 0 0 0
queue 1 309232345 450 0
queue 2 300 10 0
queue 3 91 0 0

Repeating this command results in the counters incrementing for queue 1 threshold 1.
What are two options for reducing the packet loss on this interface while preserving the end-to-end DSCP marking? (Choose two)
