Answer : C

FlexGrid is a flexible grid technology that allows for variable channel spacing and bandwidth allocation. It uses the same sets of boards as the traditional fixed grid systems and it does not require upgrading the old generation WDM systems.

Answer : C

Services are transported over trails; that is, services are clients with respect to trails. A service is a logical connection that is used to transport data from one point to another. It is created over a trail, which is a physical connection that is established by using multiple wavelengths. As such, services are clients with respect to trails, as they are transported over them.

Answer : A

A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.

Answer : D

The NFM-T (Network Functions Manager - Transport), now part of the WaveSuite Network Operations Center (WS-NOC), is the centralized management system for Nokia's optical portfolio. The Deploy menu is the primary engine for operationalizing the network. Its fundamental purpose is to create and provision new network instances, which encompasses the lifecycle of the transport infrastructure.

Specifically, this menu allows operators to establish physical connections (fiber links between nodes), build out the infrastructure (defining the topology and node roles), and most importantly, provision services (such as ODUk or Optical Channel services). While the EPT (now WaveSuite Planner) designs the network, and those files can be used as a reference, the actual 'birth' of a service in the live network---mapping it from the source transponder to the destination through the required ROADM degrees---is executed via the Deploy menu. It translates the high-level intent into specific cross-connect commands sent to the individual Network Elements (NEs), ensuring that the underlying hardware is correctly configured to carry client traffic.

Answer : A

show interface 11starla 1/17/L1 detail is the correct command to check for interface details. This command will display detailed information about the specified interface, including its status, configuration, and statistics.
