The graphic shows two routers, R1 and ISP, that are connected together on a WAN link, and R1 is connected to a LAN segment. R1 is connected to the Ethernet segment on interface G0/0 with IP address 172.16.0.0/16. R1 is connected to the ISP router through interface S0/0/0 and IP address 209.165.200.224 and the ISP router uses interface S0/0/1 and IP address 209.165.200.224.Refer to the exhibit. R1 was configured with the static route command ip route 209.165.200.224 255.255.255.224 S0/0/0 and consequently users on network 172.16.0.0/16 are unable to reach resources on the Internet.

An administrator is trying to configure PAT on R1, but PC-A is unable to access the Internet. The administrator tries to ping a server on the Internet from PC-A and collects the debugs that are shown in the exhibit. Based on this output, what is most likely the cause of the problem?
The inside global address is not on the same subnet as the ISP.
Which three advantages are provided by static routing? (Choose three.)
The path a static route uses to send data is known and Static routing does not advertise over the network, thus providing better security and Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does.
Refer to the exhibit. Which would be chosen as the router ID of R2?
The router ID has to be manually configured.
The exhibit shows 3 PCs connected to a switch through Fa0/2, Fa0/3, and Fa0/4 interfaces. The switch is connected to a router through the Fa0/1 interface. The exhibit also shows this partial output from the show running-config command: <output omitted> interface FastEthernet0/1 switchport trunk allowed vlan 10,20,30 switchport mode access switchport nonegotiate ! interface FastEthernet0/2 switchport access vlan 10 switchport mode access switchport nonegotiate ! interface FastEthernet0/3 switchport access vlan 20 switchport mode access switchport nonegotiate ! interface FastEthernet0/4 switchport access vlan 30 switchport mode access switchport nonegotiate Refer to the exhibit. Inter-VLAN communication between VLAN 10, VLAN 20, and VLAN 30 is not successful. What is the problem?
The switch interface FastEthernet0/1 is configured as an access interface and should be configured as a trunk interface.
