A network administrator has subnetted the 172.16.0.0 network using a subnet mask of
255.255.255.192. A duplicate IP address of 172.16.2.120 has accidentally been configured on a workstation in the network. The technician on the plant floor must assign this workstation a new IP address within that same subnetwork. Which address should be assigned to the workstation?

• A.172.16.2.128
• B.172.16.1.64
• C.172.16.2.127
• D.172.16.2.64
• E.172.16.1.80
• F.172.16.2.80

Exhibit:

Refer to the exhibit. A technician enters the exhibited commands to configure a new router on the plant floor, but receives an error message when attempting to save the configuration. What can the technician do to correct the problem?

What do deflections indicate to the time domain reflectometer user?

• A.They are used to select the I/O impedance of the time domain reflectometer. You can select 50, 75, 95, or 125? impedances.
• B.Do not connect live circuit cables to the input of the time domain reflectometer. Connect the cable that is being tested to the cable connector on the front panel of the time domain reflectometer.
• C.They indicate splices, water in the cable, split pairs, and discontinuities or faults.
• D.Upward deflections indicate high-impedance mismatches or opens, and downward deflections indicate shorts or low-impedance mismatches.

What is the purpose of a time domain reflectometer?

• A.It opens kinks and mismatched cable connectors.
• B.It correlates the returned light pulses with a location in the fiber.
• C.It opens shorts and pinholes in cable shielding.
• D.It uses pulses to locate and test for sheath faults, damaged conductors, loose connectors, splices, bridge taps, split pairs, and other problems.
