R2# show ip nat statistics

Refer to the exhibit. An administrator is configuring NAT to provide Internet access to the inside network. After the configuration is completed, users are unable to access the Internet. What is the cause of the problem?

The NAT inside source command is referring to the wrong ACL.

Which statement is a characteristic of SNMP MIBs?

The NMS must have access to the MIB in order for SNMP to operate properly.

A network administrator is configuring a PPP link with the commands: R1(config-if)# encapsulation ppp R1(config-if)# ppp quality 70 What is the effect of these commands?

The PPP link will be closed down if the link quality drops below 70 percent.

Refer to the exhibit. A network administrator has implemented the configuration in the displayed output. What is missing from the configuration that would be preventing OSPF routing updates from passing to the Frame Relay service provider?

The broadcast keyword has not been issued.

What is the expected behavior of an ADSL service?

The download rate is faster than the upload rate.

What is a characteristic of Frame Relay that allows customer data transmissions to dynamically "burst" over their CIR for short periods of time?

The physical circuits of the Frame Relay network are shared between subscribers and there may be times when unused bandwidth is available.

A branch office uses a leased line to connect to the corporate network. The lead network engineer confirms connectivity between users in the branch office, but none of the users can access corporate headquarters. System logs indicate that nothing has changed in the branch office network. What should the engineer consider next to resolve this network outage?

The service provider for the branch office should troubleshoot the issue starting from the point of demarcation.

Refer to the exhibit. Router R1 was configured by a network administrator to use SNMP version 2. The following commands were issued: R1(config)# snmp-server community batonaug ro SNMP_ACL R1(config)# snmp-server contact Wayne World R1(config)# snmp-server host 192.168.1.3 version 2c batonaug R1(config)# ip access-list standard SNMP_ACL R1(config-std-nacl)# permit 192.168.10.3 Why is the administrator not able to get any information from R1?
