QUESTION NO: 1
Why is SSH preferred over Telnet as a method of accessing a network device to alter or view the configuration?

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

Correct Answer: A

QUESTION NO: 2
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. Both standard controllers must monitor a photocell on this machine. Which IP address is used to transfer this status information?

A. 239.192.254.16 B. 10.17.104.16 C. 239.192.3.16 D. 192.168.1.16

Correct Answer: C

QUESTION NO: 3
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. DLR is the only resiliency technology that is supported by CIP Safety C. Layer 2 resiliency protocols like REP and RSTP do not have a fast enough convergence time for motion control D. Half of the network traffic goes clockwise on the ring and the other half counter- clockwise, reducing by 50% the impact of cable failure E. Moving to a linear topology will reduce the number of cables and so reduce risk of cable failure

Correct Answer: A,C

QUESTION NO: 4
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 assigned ProfiNET VLAN is not valid and should be less than 100 B. The Reduction Ration has been set too low C. The GSD file version on the switch does not match the GSD file version on the management station D. LLDP has been disabled on this switch

Correct Answer: C

QUESTION NO: 5
Which statement is correct regarding Media Redundancy Protocol (MRP) in a ring of
ProfiNET devices?

A. When a link fault is detected, MRP rings must converge in less than 100 milliseconds B. MRP is only supported on network switches C. MRP can support rings of up to 250 devices D. MRP defines two device roles, Media Redundancy Master and Media Redundancy
Client

Correct Answer: D

QUESTION NO: 6
Refer to the exhibit.

What issue does this topology present for the represented traffic flow?

A. I/O control traffic should utilize the 2.4 GHz band based on best practices. B. Standard Produce/Consume traffic is not suitable for an 802.11 wireless environment. C. The Converged Plant-wide Ethernet best practices for 802.11 wireless don't allow for
PAC to PAC traffic. D. Only one of the Work Group Bridges can transmit at a time, because 802.11 is half duplex.

Correct Answer: D

QUESTION NO: 7
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?

A. Oxidation on Shielded RJ45 Patch Plug B. Use of shielded Patch Cables, Bonded on one end only. C. Broken seal on bulkhead connector. D. Use of unshielded Patch Cables.

Correct Answer: A

QUESTION NO: 8
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 Host B 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 the VLAN 1 interface on SW-C and other devices in the network.

Correct Answer: D

QUESTION NO: 9
Refer to the exhibit.

L3SW1 has a spanning-tree priority of 8192 set on VLANs 1, 300, and 301, and these
VLANs are configured on and trunked between all switches. Executing the command show spanning-tree blockedports on L2SW5 results in:
L2SW5# show spanning-tree blockedports
Name Blocked Interfaces List
-------------------- ------------------------------------
VLAN0001 Gi1/1
VLAN0300 Gi1/1
VLAN0301 Gi1/1
An additional VLAN, VLAN302, is defined on all switches and trunked between them.
VLAN302 access ports are set up on each of the switches and PLC#1, I/O#1, and the
PanelView are attached. You expect the new VLAN to be listed as blocked on interface
GigabitEthernet1/1 of L2SW5 but it is not. The three new devices are able to communicate with each other.
After executing the same command on all switches you see this output on L2SW4:
L2SW4# show spanning-tree blockedports
Name Blocked Interfaces List
-------------------- ------------------------------------
VLAN0001 Gi1/2
VLAN0300 Gi1/2
VLAN0301 Gi1/2
Why is VLAN302 forwarding on L2SW5 interface GigabitEthernet 1/1 and L2SW4 interface
GigabitEthernet 1/1 and 1/2?

A. VLAN302 is not configured in the VLAN database on L2SW5 B. The FO3 fiber-optic cable between L2SW4 and L2SW5 is damaged C. VLAN302 is not in the allowed list on the L2SW5 interface GigabitEthernet1/1 trunk D. L2SW4 is the spanning tree root for VLAN 302
