Questions 1

Which of the following statements about the operation of seamless-BFD is FALSE?

Options:

Seamless-BFD responses are sent back using the LSP label stack.

To be able to respond to seamless-BFD messages, a router must be configured as a reflector.

A seamless-BFD template needs to be configured on the head-end of the LSP.

The routing protocol (OSPF or IS-IS) is used to carry the reflector discriminator information.

examstrack.com's 4A0-116 testing engine is phenomenal. It made me feel confident for the certification exam.

Questions 2

When OSPF is used to support Segment Routing, the first byte of the link-state ID associated with each of the opaque LSAs indicates the type of information being advertised. Which of the following associations between the first-byte value and its meaning is FALSE?

Options:

Value 1 - Traffic Engineering

Value 4 - Router Info

Value 7 - SRGB Range

Value 8 - Extended Link Info

Questions 3

Which of the following is NOT an advantage of using a PCE for the computation of TE-constrained LSP paths, as compared to using CSPF locally on the PE router?

Options:

The ability to create cross-area TE-constrained LSP paths

The ability to create LSP paths with bandwidth reservation

The ability to create LSPs with primary and secondary paths

The ability to ensure that some LSP paths are disjoint

Questions 4

Which of the following statements about a Segment Routing SID is FALSE?

Options:

A Node-SID is usually associated with a router's system interface.

Adjacency-SID values are taken from the SRGB configured for the routing protocol.

A Prefix-SID can be configured directly as a label value or indirectly as an index.

An Adjacency-SID does not have to be configured.

Questions 5

OSPF is being used for segment routing with traffic-engineering (SR-TE). The traffic-engineering option has been set to "sr-te false". Which of the following statements is TRUE?

Options:

The TE information will be advertised for all the OSPF links that have MPLS enabled.

The TE information will only be advertised using application-specific sub-TLVs.

The TE information will only be advertised for the OSPF links that have both MPLS and RSVP enabled.

The TE information will only be advertised using extended-link opaque LSAs.

Questions 6

Which of the following types of information is considered by a stateless PCE when it processes a new LSP path calculation request?

Options:

The IGP link-state database

The traffic-engineering database

The operational state of existing LSP paths

The amount of bandwidth reserved for each of the existing LSP paths

Questions 7

OSPF type-10 Opaque LSAs can carry different types of advertisements. What type of advertisement carries a router's local 5RGB information?

Options:

Extended Prefix Info

Router Info

Extended Link Info

Traffic Engineering Info

Questions 8

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

Options:

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

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

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

A stateful PCE can allow LSPs to reserve bandwidth.
