Options:

The router receives a link-state update in response to a link-state request.

Question # 104

If router R2 redistributes the IS-IS route to 192.168.3.0/24 into OSPF, router R3 will receive two routes to 192.168.3.0/24. What will be the preference of these two routes? Assume that all IS-IS routers are L1/L2 capable and are in the same area. Choose two answers.

Options:

The OSPF internal preference

The IS-IS Level 1 internal preference

The IS-IS Level 2 internal preference

The OSPF external preference

The IS-IS Level 2 external preference

The IS-IS Level 1 external preference

Questions # 105:

An OSPF adjacency is stuck in the exstart state. What is the most likely cause?

Options:

The MTU does not match on both interfaces.

OSPF is not enabled on one of the routers.

The router ID is the same on both routers.

An OSPF Hello has not been received from the neighbor.

The interfaces are configured as point-to-point on one side and broadcast on the other.

Question # 106

OSPF is operational on all links in the network diagram, all links are the same cost, and all routers are configured with an ECMP value of 4. Router R4 advertises the prefix 192.168.3.0/24 into OSPF.

How many entries for prefix 192.168.3.0/24 will be in router R5's routing table?

Questions # 107:

Which of the following commands may only be used on the head end router to verify the status of an LSP named "LSP 1"? (Choose two)

Options:

show router mpls Isp "LSP 1" originate

show router mpls Isp "LSP 1" path detail

show router rsvp session originate

show router rsvp session "LSP 1"

Questions # 108:

If routers R1 and R2 have a Level 1 and Level 2 IS-IS adjacency, which of the following statements are true? Choose two answers.

Options:

Routers R1 and R2 are in different areas,

Routers R1 and R2 are in the same area.

Routers R1 and R2 will send a Level 1 Hello PDU and Level 2 Hello PDU, if the interface type between them is point-to-point.

Routers R1 and R2 will send a Level 1 Hello PDU and Level 2 Hello PDU, if the interface type between them is broadcast.

Routers R1 and R2 will send a Level 1/2 Hello PDU, if the interface type between them is broadcast.

Questions # 109:

Why does IPv6 not use ARP?

Options:

The ARP functionality has been replaced by the Neighbor Discovery protocol.

The ARP functionality is not needed due to the increased IPv6 address space.

ICMPv6 reduced its role to connectivity checking and auto-configuration only.

ICMFV6 replaced the ARP functionality with Multicast Listener Discovery (MLD).

Questions # 110:

Which OSPFv3 LSA advertises the location of an ASBR?

Options:

Intra-Area Prefix LSA

Inter-Area Prefix LSA

Inter-Area Router LSA

AS External LSA

Options:

10.10.10.2

10.10.10.3

10.10.10.4

10.10.10.6

There is no ASBR configured in the network.

Questions # 112:

Question # 112

- The protected path is R1-R2-R3-R6.

- Fast reroute one-to-one protection is enabled.

If the original LSP already has two labels, and router R2 has failed, how many labels will there be in packets on the detour path?

Question # 113

Assuming point-to-point links, which of the following is TRUE?

Options:

Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1/L2 routers.

Routers R1, R2, and R4 are L1/L2 routers Router R3 is an L1 router.

Routers R1, R2, and R3 are L2 routers. Router R4 is an L1 router.

Routers R1 and R2 are L1/L2 routers. Routers R3 and R4 are L1 routers.

Questions # 114:

Assume that, on the Alcatel-Lucent 7750 SR, an LSP is configured with one-to-one FRR and node protection. Which of the following statements are FALSE? (Choose two)

Options:

Each PLR signals a detour LSP that avoids the downstream node. If the downstream node cannot be avoided, a detour LSP that avoids the downstream link is signaled.

The detour LSP can take one or more hops before merging back on the protected LSP.

The merge point of the protected LSP must be the next-next-hop node

The ingress router will set the local protection desired flag in the session attribute object of the path message to inform all routers along the protected LSP path to establish detour LSPs.

The label recording desired flag must be set in the session attribute object in order for the PLR to know what label to swap when using the detour LSP.

Questions # 115:

How does MPLS-TE overcome the issue of IP hyper-aggregation?

Options:

By enabling the creation of LSPs across alternate links to balance the network traffic.

By eliminating the requirement for core IP routing.

By not allowing more than one LSP to use a particular path.

By defining multiple LSPs across a network and implementing an IGP load balancing algorithm across them.

Questions # 117:

LDP is enabled on both ends of a point-to-point link, but the "show router Idp status" command indicates that LDP is operationally down. The Oper Down Reason field shows the message "systemIpDown." What might cause this condition?
