The exhibit represents a simple routed network. Node 7 is a Windows 2000 Professional machine that establishes a TCP communication with Node 10, a Windows 2003 Server. The routers are Cisco 2500 series running IOS 11.2.

While working at Node 10, you run a packet capture. Packets received by Node 10, and sent from Node 7 will reveal which of the following combination of source IP and source Physical addresses:

You have implemented an IPSec policy, using only AH. You are analyzing your network traffic in Network Monitor, which of the following statements are true about your network traffic?

In order to perform promiscuous mode captures using the Wireshark capture tool on a Windows Server 2003 machine, what must first be installed?

A router has two active Ethernet interfaces. Interface E0 is connected to network 10.10.0.0/16 while Interface E1 is connected to network 10.11.0.0/16. You are configuring access control lists to manage specific access, which is disallowed on these segments. The configuration of the lists are as follows:

router(config)#access-list 123 deny tcp 10.11.0.0 0.0.255.255 10.10.0.0 0.0.255.255 eq 20
router(config)#access-list 123 deny tcp 10.11.0.0 0.0.255.255 10.10.0.0 0.0.255.255 eq 21
router(config)#access-list 123 deny tcp 10.10.0.0 0.0.255.255 10.11.0.0 0.0.255.255 eq 20
router(config)#access-list 123 deny tcp 10.10.0.0 0.0.255.255 10.11.0.0 0.0.255.255 eq 21
router(config)#access-list 123 permit tcp 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
router(config)#Interface Ethernet 0
router(config-if)#ip access-group 123 in
router(config-if)#Interface Ethernet 1
router(config-if)#ip access-group 123 in

Based on the above list configuration, which of the following statements is true on the router?
