Questions # 1:

Which of the following list of SR-TE attributes has to be advertised among routers?

Options:

Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to.

Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to.

Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to, link status up/down.

Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to, link status up/down.

Answer

Explanation

In SR-TE, routers need to advertise certain attributes of their links to other routers in the network in order to calculate traffic-engineered paths. These attributes include:

Administrative groups that each link belongs to: This information is used to restrict the use of certain links to specific traffic types or groups.

TE metric of links: This information is used to calculate the cost of using a particular link for a traffic-engineered path.

Bandwidth availability of each link: This information is used to control the amount of traffic that can be sent over a particular link.

SRLG that each link belongs to: This information is used to avoid routing over the same physical link. Link status up/down is not needed to be advertised as it is part of the IGP protocol and is used to check the reachability of a link.

Questions # 2:

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

Options:

A local Node-SID can be configured directly as an MPLS label.

A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index.

All routers do NOT need to have the same SRGB range configured.

A local Node-SID can be configured as an index.

Answer

Explanation

A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index: This statement is not true, A router will advertise its local Node-SID as a local SRGB and an index, whether it is configured as an index or not.

Questions # 3:

Based on the configuration shown for routers R1 and R10, what valid flex-algo definitions exist in the network?

Question # 3

Options:

No valid flex-algo definitions, because of the conflicting parameters.

One valid flex-algo definition, using delay as the link metric and including green links.

One valid flex-algo definition, using te-metric as the link metric and including blue links.

Two valid flex-algo definitions, one uses te-metric as the link metric and includes blue links and the other uses delay as the link met includes green links.

Answer

Questions # 4:

Examine the exhibit.

Question # 4

An LSP is being configured to start at R1and end at R6 using local CSPF. The LSP has the following constraints. Include admin-group GREEN, use the TE metric and hop-limit 3. What routers will be included in the LSP path?

Options:

R1, R2, R4, R6

R1, R5, R6

R1, R3, R5, R6

R1, R6

Answer

Questions # 5:

In which of the following aspects does the configuration of flex-algo LSPs have an advantage over the configuration of SR-TE LSPs?

Options:

Label stack size of the encapsulated data packets

List of traffic-engineering constraint types available to choose from

Ability to associate one primary and up to two secondary paths to the same LSP

Flexibility of configuring each LSP with its own set of traffic-engineering constraints

Answer

Explanation

Flex-Algo LSPs are a type of LSP that allows for greater flexibility in configuring traffic engineering constraints. This is because flex-algo LSPs can be configured with a unique set of traffic engineering constraints for each LSP, whereas SR-TE LSPs use a predefined set of traffic engineering constraints that applies to all LSPs.

Label stack size of the encapsulated data packets, List of traffic-engineering constraint types available to choose from, and Ability to associate one primary and up to two secondary paths to the same LSP are not the advantages of flex-algo LSPs over SR-TE LSPs.

Questions # 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:

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

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

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

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

Answer

Questions # 7:

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

Answer

Questions # 8:

Based on the exhibit, which of the following statements about fast re-route for flex-algo instance 129 is TRUE?

Question # 8

Options:

Only standard LFA is enabled on router R1; fast re-route is not enabled on router R2.

Only standard LFA is enabled on both routers R1 and R2.

Standard LFA and remote-LFA are enabled on router R1; fast re-route is not enabled on router R2.

Standard LFA and remote-LFA are enabled on router R1; standard LFA and TT-LFA are enabled on router R2.

Answer

Questions # 9:

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.

Answer

Explanation

When using Segment Routing with Traffic Engineering (SR-TE) in OSPF, the TE information is advertised using extended-link opaque LSAs. The option "sr-te false" indicates that OSPF will not advertise the TE information in the OSPF database, thus the routers will not be aware of the TE information.

Questions # 10:

Which of the following statements about path definitions is FALSE?

Options:

Once a path is associated with an LSP, it cannot be used by other LSPs.

A loose hop is one that does not have to be directly adjacent to the previous hop in the path list

The path hops can be defined by either the system or physical interface IP address.

In addition to the hops defined in the path list, the head-end and tail-end routers are implicitly added.
