Answer

Questions # 33:

On an Nokia 7750 SR, what is the recommended approach for making sure that MTUs between a VPLS and its spoke IES termination match?

Options:

Set the service MTU of the VPLS to match the IES MTU.

Set the ip-mtu of the IES to match the service MTU of the VPLS.

Set the SDP MTU of the IES to match the SDP MTU of the VPLS.

Set the MTU of the IES's network port to match the service MTU of the VPLS.

Answer

Questions # 34:

Which of the following is NOT a goal of BGP routing policies?

Options:

To protect external networks from instability.

To communicate the architecture of an AS to external ASs.

To protect the local AS and other external ASs from bad NLRI.

To optimize ingress and egress traffic patterns to best serve the users of the AS.

Answer

Questions # 35:

A static route is created using the command "static-route 2.3.4.0/24 next-hop 1.2.3.4". What is the correct traceroute command to test this static route on an Nokia 7750 SR?

Options:

traceroute 2.3.4.1

traceroute 2.3.4.0/24 next-hop 1.2.3.4

traceroute next-hop 1.2.3.4

traceroute does not work on the Nokia 7750 SR

Question # 36

An LSP path is established on router R1 toward router R6. If there is a problem on router R4, but the link between R2 and R4 remains up, which of the following will affect the failure detection time?

Options:

The time router R2 takes to receive a PATH Error message from router R4.

The time router R2 takes to find out a number of RSVP Hello messages have been missed.

The time router R2 takes to send a PATH Tear message to the head-end router.

The time router R2 takes to receive a PATH message from router R4 after a PATH refresh interval.

Answer

Questions # 37:

Which of the following is NOT a characteristic of MPLS?

Options:

It provides the ability to establish connection oriented paths over a connectionless IP network.

It provides a mechanism to engineer network traffic patterns independently of IP routing tables.

It will work over most physical layer protocols.

It can use GRE tunnels to transport data from many different protocols over an IP network.

Answer

Questions # 38:

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

Options:

In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.

In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30

In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

Answer

Questions # 39:

Which of the following statements regarding OSPF routing updates on a point-to-point link is true?

Options:

On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to 224.0.0.5.

On a point-to-point link, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

On a point-to-point link, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

On a point-to-point link, there is no need for a DR and BDR election. All routing updates are sent to the unicast address of the neighbor's interface.
