NEW QUESTION 145
What characteristic of IP addressing creates a hierarchical network?

All hosts on all networks must have unique host numbers.

IP addresses identify a host and the network on which it resides.

Clients are assigned 32-bit addresses and servers 64-bit addresses.

NEW QUESTION 146
A 24 port Ethernet switch is configured with VLAN 100 on ports 1 – 8, VLAN 200 on ports 9 – 16 and VLAN
300 on ports 17 – 24. Which of the following describes the behavior of the switch when a broadcast frame is received on port 1?

NEW QUESTION 148
From the CE perspective, how does a VPLS operate?

A VPLS operates as if 2 sites are directly connected by a single cable.

A VPLS operates as if multiple sites are connected through a single switched LAN.

A VPLS operates as if multiple sites are connected through a single router.

A VPLS operates as if multiple sites are connected through a series of private point-to-point routed connections.

NEW QUESTION 149
Which of the following best describes a repeater?

A passive device simply used to connect two or more cables. It does not generate or amplify any
signals.

A device that receives and retransmits a signal out its ports but does not do any Layer 2 analysis of the
data.

A device that receives a signal and based on the Layer 2 destination address, makes a decision on
which ports the signal should be retransmitted.

A device that receives a signal and based on the Layer 3 destination address makes a decision on
which ports the signal should be retransmitted.

NEW QUESTION 150
Which of the following are TRUE statements about the router ID in OSPF? Choose two

A router ID is not required by OSPF.

The system address is used as the router ID if router-id is not set.

The router ID is used to uniquely identify every OSPF router.

On the Alcatel-Lucent 7750 SR, the router ID is set to the highest logical IP address if router-id is not explicitly set.

NEW QUESTION 151

Node Management Terminal Interface (NMTI).

Command Line Interface (CLI).

All of the above.

NEW QUESTION 152
Which of the following is a characteristic of Distance Vector protocols?

Routers periodically send a copy of their table to their neighbors.

Routers send triggered updates to the entire network.

Routers know the entire network topology.

Routers use Shortest Path First algorithm to calculate the optimum paths.

NEW QUESTION 153
What does a device do when it receives an ICMP Echo request message that is destined for itself, it then:

Estimates the round trip-time.

Generates an echo reply message.

Calculates the data loss statistics.

Verifies the data field of the message.

NEW QUESTION 154

/25

/26

/28

/30

NEW QUESTION 158
Which of the following statements is TRUE of Layer 3 addressing?

Internet devices on the same network can have the same Layer 3 address in different broadcast domains.

Every Host device must have a unique Layer 3 address in order to access the Internet.

Internet devices need unique Layer 3 addresses to communicate directly with upper layers.

A router must have only one address to allow it to be uniquely identified.

NEW QUESTION 159

Well known port numbers are used by both TCP and UDP. Well known port numbers range from 1 to 1023 and are assigned by IANA.

Well known ports numbers are used by TCP only. Well known port numbers are assigned by IANA and can have any value.

NEW QUESTION 165
How does a VPRN service avoid the problem of overlapping IP addresses from different customers?

You cannot have overlapping IP addresses. The service provider must ensure that its customers are all using discrete IP address space.

Each VPRN service maintains a separate VPN routing and forwarding instance to separate customer routing information.

A VPRN will ignore IP addressing information and use MAC addressing instead which are always unique.

A VPRN will translate customer IP addresses to a private addressing scheme administered by the service provider.
