Question 1

Which of the following statements about enabling and using traffic engineering for Segment Routing is FALSE?

AOne interface can belong to an admin group and SRLG group at the same time.

BA link attribute has to be assigned to a particular interface under the [/configure router interface] context

CBandwidth availability as a link attribute cannot be configured.

DThe interfaces used for SR-TE LSPs have to be added to the MPLS context.

Answer : C

Bandwidth availability can be configured as a link attribute in SR-TE, it is used to control the amount of traffic that can be sent over a particular link.

Question 2

A router participating in SR-TE is advertising a value of Ox11 for the admin-group membership of one of its interfaces. Which of the following statements is TRUE?

AThe interface belongs to admin group RED, configured with a value of 17.

BThe interface belongs to two different admin groups.

CThe interface belongs to three different admin groups.

DThe interface belongs to four different admin groups.

Answer : B

In SR-TE, the admin-group is represented by a 32-bit value, where each bit represents a different admin-group. The value Ox11 in binary is 000100010001, which has two bits set to 1, indicating that the interface belongs to two different admin groups. The exact admin-groups that the interface belongs to depends on how the admin-groups have been configured on the router.

Question 3

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

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

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

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

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

Answer : C

Question 4

Examine the exhibit.

An LSP is being configured to start at R1 and 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?

AR1, R2, R4, R6

BR1, R5, R6

CR1, R3, R5, R6

DR1, R6

Answer : C

Question 5

Which of the following statements about path definitions is FALSE?

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

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

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

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

Answer : C

Question 6

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

AThe IGP link-state database

BThe traffic-engineering database

CThe operational state of existing LSP paths

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

Answer : A

Question 7

Which of the following is not required to be advertised by a router participating in Segment Routing?

ALocal Node-SID

BAdjacency-SIDs

CSupport for SR-MPLS for IPv4 or IPv6, or SRv6

DSRGB when SRv6 is configured

Answer : D

SRGB when SRv6 is configured: This is not required to be advertised, SRGB(Segment Routing Global Block) is only used for SR-MPLS and is not needed when SRv6 is configured. Instead, SRv6 uses the IANA-assigned IPv6 address space.
