NEW QUESTION 19
How are L0 and L1 resources coordinated in case of a failure in an MRN?

Coordination is achieved by setting the color constraints

Coordination is achieved by comparing the Setup Priorities

Coordination is achieved by segregation of color and colorless LSPs

Coordination is achieved by setting the WSR parameter

NEW QUESTION 20
Which of the following is not a key feature of GMPLS?

Self-discovery

Fast protection

Restoration

Resource optimization

NEW QUESTION 21
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 22
What is the GMRE notify 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 email exchange server to notify the operators of network failures

An IP address used to signal failures on downstream nodes upstream to the head node

NEW QUESTION 23
What is the Link Maintenance window?

A centralized view of the TE-link for the operator

A wizard with commands to set links and nodes to maintenance

A wizard for modifying TE-link attributes

A centralized alarm manager

NEW QUESTION 24
Which categories of protocols are included in the GMPLS technology?

Signaling, routing, and forwarding

Link management, signaling, and switching

Routing, grooming, and signaling

Routing, signaling, and link management

NEW QUESTION 25
What is the Commissioning File in GMRE nodes?

A file with commissioned GMRE nodes for NPA implementation

A file of optical impairment parameters for power balance

A file with target values that determine whether a given LSP is possible

A control checklist for the operator

NEW QUESTION 26
What does the SNC state with an uppercase “N” mean in a resource in NFM-T?

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

Indicates it’s currently using the Nominal resource assigned to it

NEW QUESTION 27
What does an SNC state of lower case “n” mean for a resource in NFM-T?

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

Indicates it’s currently using the Nominal resource assigned to it

NEW QUESTION 28
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 29
What is the function of the OSPF-TE protocol?

To monitor the availability of the links interconnecting adjacent nodes

To exchange with other nodes data about the state of links

To assign different priority to various types of transported signals

To create an MPLS tunnel between two or more end points

NEW QUESTION 30
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 31
How do you configure the Trail template in NFM-T for an Uplink board (such as 2UC400) in an MRN network with LO and LI restoration capabilities?

Check the Logical Link box
Set the Port Type to Unterminated Check the ASON Routed box Uncheck the ASON Tunnel box

Uncheck the Logical Link box Set the Port Type to Terminated Check the ASON Routed box Uncheck the ASON Tunnel box

Check the Logical Link box
Set the Port Type to Unterminated Check the ASON Routed box Check the ASON Tunnel box

Uncheck the Logical Link box Set the Port Type to Terminated Check the ASON Routed box Check the ASON Tunnel box

NEW QUESTION 32
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 33
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.
