Nokia Optical Networking Fundamentals - 4A0-205 Exam Practice Test

A. Through the pre-amplifier, the optical signal is amplified both the receiver side and at the transmitter side.

B. Through the pre-amplifier, the optical signal is amplified within the node internally to recover internal losses due, for instance, to cascaded filters.

C. Through the pre-amplifier, the optical signal is amplified at the transmitter side before it is sent to the line span.

D. Through the pre-amplifier, the optical signal is amplified at the receiver side after it travels along the fiber from another node.

A. These windows correspond to three different minimum and maximum optical power levels used for optical transmission.

B. These windows are three different wavelength intervals where the WDM optical transmission occurs.

C. Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.

D. These three windows are three different angles of incidence of the light injected by the laser into the fiber.

A. The systems are displayed on the CPB panel and they can be individually selected

B. The systems are not reported on CPB, but only through the Equipment Manager

C. The systems are not reported on CPB, as this Is transparent to the user and the whole network is validated and provisioned in one step

D. The systems are displayed on the CPB panel, however they cannot be individually selected as they need to run all together

A. display alarms

B. show active alarms

C. retrieve alarms

D. alm

A. Demand refers to the amount of OTN interfaces within a single network element.

B. Demand refers to one or more client signal.

C. Demand refers to the required capacity of a single network element in terms of bandwidth.

D. Demand refers to the required number of trails to be automatically created to meet design requirements.

A. ASON networks, to protect traffic via GMPL5 protocols

B. Backbone networks, for supporting protection routes

C. SNCP-protected links

D. Access networks, for collecting traffic towards the main central node

A. Testing a node's internal fiber connectivity before service provisioning.

B. Detecting unexpected or missing channels.

C. Tracing a service along an optical path.

D. Performing channel power monitoring.
