Questions # 181:

When a router receives an IP packet, but does not find a match in the routing table for the destination IP address, what actions are performed by the router?

Options:

The packet is flooded out all router interfaces.

The packet is dropped and an ICMP unreachable message is sent back to the source.

The packet is silently discarded.

The packet is flooded out all interfaces and an ICMP unreachable message is sent.

Questions # 182:

What best describes the type of packets used by OSPF routers to exchange updates on a pointto-point link?

Options:

IP packets sent to an IP multicast address.

Ethernet frames sent to an Ethernet multicast address.

IP packets sent to an IP unicast address.

UDP packets sent to an IP multicast address.

Questions # 183:

What is wrong with the following filter configuration from an Alcatel-Lucent 7750 SR?

RTR-B# configure filter

RTR-B>config>filter# ip-filter 1 create

RTR-B>config>filter>ip-filter$ entry 1 create

RTR-B>config>filter>ip-filter>entry$ match src-ip 172.2.0.0/16

RTR-B>config>filter>ip-filter>entry# action drop

RTR-B# configure router interface toRTR-A

RTR-B>config>router>if# egress

RTR-B>config>router>if>egress# filter ip 1

Options:

There is nothing wrong with this filter

The filter should be applied to the ingress and not the egress.

The mask cannot be a "/" value, it must be in dotted decimal.

All traffic is being blocked

Options:

Option A

Option B

Option C

Option D

Questions # 185:

Which of the following cannot be used as a matching criterion in route policy statements?

Options:

Source IP address

Protocol type

Questions # 186:

Which of the statements below best describes the operation of the IPv6 anycast address?

Options:

A packet with a destination anycast address is sent to all nodes on the local link.

A packet with a destination anycast address is sent to all nodes on the local network.

A packet with a destination anycast address is sent to all nodes that have joined the anycast group.

A packet with a destination anycast address is sent to the nearest node that is assigned the anycast address

A packet with a destination anycast address is sent to all nodes that are assigned the anycast address.

Question # 187

Given the two configurations shown, identify the two incorrect statements below: (Choose two)

Options:

Both routers will generate OSPF Hello packets.

The system interface is missing in one configuration so OSPF will not operate correctly.

The interface type settings differ, but OSPF will still operate correctly.

Metric values differ, but this does not prevent OSPF operation.

Questions # 188:

How many bytes make up the system ID in an IS-IS NSAP address on the Alcatel-Lucent 7750 SR?

Options:

4 bytes

6 bytes

8 bytes

Variably between 4 and 8 bytes

Questions # 189:

An operator configures an Alcatel-Lucent 7750 SR with a loopback interface and IPv6 address. The operator then configures a routing policy to redistribute the loopback prefix into OSPFv3. What type of LSA is used to advertise the route to other OSPFv3 routers in the same area?

Options:

Router LSA

AS External LSA

Intra-Area Prefix LSA

Inter-Area Prefix LSA

Network LSA

None of the statements are correct.

Questions # 190:

Options:

Level 0

Level 1

Level 2

Level 0/1

Question # 191

Two neighboring OSPF routers have exchanged the packets shown. What state is the adjacency in?

Options:

Full; both routers are exchanging Helios to maintain the adjacency.

The adjacency is down.

The adjacency is in exstart state.

The adjacency is in the exchange state.

Questions # 192:

At what point is the LSP SRM flag cleared when an LSP is sent on an IS-IS point-to-point link?

Choose two answers.

Options:

As soon as the LSP is transmitted.

When an acknowledgment is received in the form of PSNP.

When an older LSP is received.

When a newer or same aged LSP is received.

Only when a newer LSP is received

Questions # 193:

Two directly connected routers set different interface Hello timeout values. Router R1 uses 15 seconds, while router R2 uses 30 seconds. Which of the following best describes the LDP adjacency?

Options:

The adjacency forms with the lower timeout value.

The adjacency forms with the higher timeout value.

The adjacency is in init state.

The adjacency times out after 30 seconds.

Questions # 194:

What can the sdp-ping command be used for? (Choose 2)

Options:

To determine the path MTU to the far-end IP address over an SDP.

To determine the service MTU of the service using an SDP.

To determine the presence of hosts using the service

Questions # 195:

Options:

Questions # 196:

Which of the following about Link TLVs found inside Type 10 Opaque LSAs is FALSE?

Options:

Link TLVs are used to advertise administrative group information.

Link TLVs are exchanged once RSVP is enabled on the interfaces.

Link TLVs are used to advertise router-IDs.

Link TLVs are used to advertise bandwidth information.
