Indicates it’s using a link other than the Nominal

Indicates the nominal resource on a TE-link that is not in use

Indicates if s a higher alarm state level

NEW QUESTION 16
Which label is swapped in an MPLS label stack at an intermediate node?

The label on the bottom

The label with the highest value

The label with the lowest value

The label on the top

NEW QUESTION 17
What is the purpose of the Upstream Label Object in RSVP-TE?

It allows for a label to be suggested to provision bidirectional LSPs.

It signals resource reservation information to upstream nodes.

It allows a node to restrict the labels that may be used downstream.

It indicates the LSP flow direction.

NEW QUESTION 18
What is the meaning of Generalized in GMPLS?

Switching can be based on values other than the label

The label can assume an extended value range, and is not constrained as it is with MPLS

Unlike MPLS, GMPLS supports multi-vendor networks

GMPLS can be used for traffic types other than data packets

NEW QUESTION 19
Which of the following is not a key feature of GMPLS?

Self-discovery

Fast protection

Restoration

Resource optimization

NEW QUESTION 20
What is the GMRE node address?

The OSPF-TE broadcast IP used to flood the link adjacency information

The LMP Control Channel ID. This field contains the IPv4 address of the ingress LER as a global unique identifier

The IP address for communication between NEs

An IP address for CORBA communication with the NMS

NEW QUESTION 21
How do you add a 3R resource to the NPA in NFM-T?

The 3R is added in the Node panel and automatically added to the NPA

The 3R is added to the NPA through the Constraint Wizard

The resource is discovered automatically

The trail is provisioned with 3R constraints and discovered automatically

NEW QUESTION 22
What is Tunnel Property Heritage?

The hierarchy tunnels cannot be nested unless they share the same properties.

Maximum allowed bandwith is propagated from HO to LO LSPs.

A restored tunnel inherits the ODUk flows.

Cost, SRLG, and Color properties are propagated from HO to LO LSPs.

NEW QUESTION 23
Which of the following best describes the Soft Shutting Down state in the NFM-T?

An automatic shutdown of a TE-link and all of the LSPs in the TE-link

A soft synchronization state where new traffic is not allowed

An administrative maintenance state where services stay up but no new traffic can be routed over the TE-link

A transient state where current SNCs are soft-rerouted away from the TE-link

NEW QUESTION 24
What does Test Mode do in an SNC?

The LSP will not be restored and will behave like an unprotected service

It initiates the LMP link verification by sending Test Messages

Source nodes of affected client services will not be notified in case of failure

It clears the ASONTOPO alarms

NEW QUESTION 25
How can you modify the SNC Nominal Route in NFM-T?

By changing the SRG constraints

By using the Reroute Wizard to modify the constraints

By using the Constraint Wizard to modify the constraints

By putting the LSP in Test mode and moving traffic

NEW QUESTION 26
What category of protocols is used by the ingress router to set up a new LSP?

Coloring protocols

Signaling protocols

Link management protocols

Link aggregation protocols

NEW QUESTION 27
What is the purpose of preemption when establishing an LSP?

To measure the end-to-end latency

To pick the next hop during LSP signalling

To tear down an existing LSP in order to accommodate higher priority traffic

To assign the correct wavelengths depending on the type of traffic

NEW QUESTION 28
Which of the following statements best describes a distributed control plane for GMPLS?

The control plane is active in some network nodes and not in others.

Each router has software to run the GMPLS protocols and can modify the node’s switching fabric.

The network manager controls all the routing for the network.

The network is managed by more than one network management system.

NEW QUESTION 29
Which of the following statements about the Wait for Server Restoration (WSR) parameter in the MRN is correct?

When WSR is true, the LO optical channel remains in the link until the failure is fixed.

When WSR is false, if the failed optical channel can be restored at LO, the data traffic stays in the tunnel.

When WSR is true, the LO channels do not wait for the LI services to restore.

When WSR is false, the LI services do not wait for the LO restoration and restore through LI switching.
