Options:

A.  

R1, R2, R4, R6

B.  

R1, R5, R6

C.  

R1, R3, R5, R6

Question # 2

The exhibit shows the fast re-route configuration on router R1, in which both R-LFA and TI-LFA have been enabled. Assume that there are multiple potential backup paths for a given prefix. Which of the following options will router R1 use?

Question # 2

Options:

A.  

A standard LFA path that would not coincide with the path after IGP re-convergence.

B.  

An R-LFA path that would not coincide with the path after IGP re-convergence.

C.  

A D-LFA path that would not coincide with the path after IGP re-convergence.

D.  

A D-LFA path that would coincide with the path after IGP re-convergence.

Question # 3

Based on the exhibit, and given that the system IP address of router RIO is 10.10.10.10, which of the following statements is FALSE?

Question # 3

Options:

A.  

Router Rl participates in at least two flex-algo instances.

B.  

Router RIO participates in flex-algo instance 130.

C.  

The Node-SID assigned to router RIO for flex-algo instance 129 is 524338.

D.  

The underlying routing protocol being used in the network for segment routing is IS-IS.

Question # 4

Which of the following statements about the Path Computation Element (PCE) is FALSE?

Options:

A.  

The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.

B.  

A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.

C.  

A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.

D.  

A stateful PCE can allow LSPs to reserve bandwidth.

Question # 5

Which of the following statements about Multi-Protocol Label Switching networks is FALSE?

Options:

A.  

MPLS uses a signaling protocol to exchange labels between routers.

B.  

An LSR forwards data based on the MPLS labels.

C.  

An LSP is a bi-directional tunnel that uses MPLS labels to forward data.

D.  

The data is transparently carried from end to end.

Question # 6

The exhibit presents packets being transmitted inside an LSP's multi-segment primary path going from router R1 to router R8. The LSP also has a standby secondary path, and Seamless-BFD has been enabled on the primary path. The link between routers R1 and R2 fails, and fast re-route (FRR) is triggered. As a result, router R1 forwards the packets to router R3 and adds the proper FRR encapsulation to reach which router?

Question # 6

Options:

A.  

To reach router R2, which is the LSP's intended next-hop.

B.  

To reach router R5, which is the shortest way to go back to the original path.

C.  

To reach router R4, which is the tail-end of the active segment.

D.  

To reach router R8, which is the tail-end of the LSP.
