Refer to the exhibit. Which statement is true about the Frame Relay connection?

The Frame Relay connection is in the process of negotiation.

A congestion control mechanism is enabled on the Frame Relay connection.

The “ACTIVE” status of the Frame Relay connection indicates that the network is experiencing congestion.

Only control FECN and BECN bits are sent over the Frame Relay connection. No data traffic traverses the link.

 

2. What will be the result of adding the command ip dhcp excluded-address 192.168.24.1 192.168.24.5 to the configuration of a local router that has been configured as a DHCP server?

Traffic that is destined for 192.168.24.1 and 192.168.24.5 will be dropped by the router.

Traffic will not be routed from clients with addresses between 192.168.24.1 and 192.168.24.5.

The DHCP server will not issue the addresses ranging from 192.168.24.1 to 192.168.24.5.

The router will ignore all traffic that comes from the DHCP servers with addresses 192.168.24.1 and 192.168.24.5.

 

3. What are the symptoms when the s0/0/0 interface on a router is attached to an operational CSU/DSU that is generating a clock signal, but the far end router on the point-to-point link has not been activated?

3. A network administrator is tasked with maintaining two remote locations in the same city. Both locations use the same service provider and have the same service plan for DSL service. When comparing download rates, it is noticed that the location on the East side of town has a faster download rate than the location on the West side of town. How can this be explained?

The West side has a high volume of POTS traffic.

The West side of town is downloading larger packets.

The service provider is closer to the location on the East side.

More clients share a connection to the DSLAM on the West side.

Refer to the exhibit. What is the meaning of the term dynamic in the output of the command?

The bandwidth capability of the interface increases and decreases automatically based on BECNs.

The Serial0/0/1 interface acquired 172.16.3.1 from a DHCP server.

The mapping between DLCI 100 and 172.16.3.1 was learned through Inverse ARP.

DLCI 100 will automatically adapt to changes in the Frame Relay cloud.

Refer to the exhibit. What can be concluded from the exhibited output of the debug ip nat command?

The 10.1.1.225 host is exchanging packets with the 192.168.0.10 host.

The native 10.1.200.254 address is being translated to 192.168.0.10.

The 192.168.0.0/24 network is the inside network.

Port address translation is in effect.
