What is the purpose of entering the command ip nat inside source static tcp 192.168.10.2 80 209.165.200.223 8080 at the global configuration prompt?
It binds the inside local address and local port to the specified inside global address and global port.
What is the most likely scenario in which the WAN interface of a router would be configured as a DHCP client to be assigned a dynamic IP address from an ISP?
It is a SOHO or home broadband router.
What is correct in relation to NAT for IPv6?
It is a temporary mechanism to assist in the migration from IPv4 to IPv6.
Which statement accurately describes dynamic NAT?
It provides an automated mapping of inside local to inside global IP addresses.
An administrator issued the following commands on router R1: R1(config)# logging 192.168.10.2 R1(config)# logging trap 5 What conclusion can be drawn from this configuration?
Messages with severity level of 6 or higher appear only on the router console output.
Refer to the exhibit. The NAT configuration applied to the router is as follows: ERtr(config)# access-list 1 permit 10.0.0.0 0.255.255.255 ERtr(config)# ip nat pool corp 209.165.201.6 209.165.201.30 netmask 255.255.255.224 ERtr(config)# ip nat inside source list 1 pool corp overload ERtr(config)# ip nat inside source static 10.10.10.55 209.165.201.4 ERtr(config)# interface gigabitethernet 0/0 ERtr(config-if)# ip nat inside ERtr(config-if)# interface serial 0/0/0 ERtr(config-if)# ip nat outside Based on the configuration and the output shown, what can be determined about the NAT status within the organization?
Not enough information is given to determine if both static and dynamic NAT are working.
Which statement describes a syslog server characteristic?
One advantage of viewing syslog messages on a syslog server is the ability to perform detailed searches through the data.
Refer to the exhibit. A network administrator wants to create a standard ACL to prevent network 1 traffic from being transmitted to the Research and Development network. On which router interface and in which direction should the standard ACL be applied?
R2 Gi0/0 outbound
Which step should be performed first when deleting a VLAN that has member switch ports?
Reassign all VLAN member ports to a different VLAN.
Refer to the exhibit. Router R2 is configured with static NAT. Place in order the steps that occur when the client accesses the web server through the router. (Not all options are used.) Step 1 Step 2 Step 3 Step 4 Step 5
Step 1 The client uses the inside global address of the web server as the destination address to send a packet to the web server. Step 2 R2 receives the packet on its outside interface, then checks and locates the destination address in its NAT table. Step 3 R2 replaces the inside global address with the inside local address of the web server and forwards the packet to the web server. Step 4 The web server uses the outside global address of the client as the destination address when responding. Step 5 R2 receives the packet from the web server. R2 checks the NAT table, then translates the source address of the web server into an inside global address and forwards the packet.
A network engineer purchases, installs, and activates a license key on a Cisco 2911 ISR G2 router. What is the next step in the installation process?
Reload the router.
Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address?
Router# show ip dhcp binding
A network administrator wants to examine the active NAT translations on a border router. Which command would perform the task?
Router# show ip nat translations
In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?
SLAAC
An administrator wants to send log messages for all severity levels from a router to its console. Which procedure should the administrator follow to accomplish this?
The administrator needs to do nothing, because Cisco routers send log messages for all severity levels to the console by default.
When a client is requesting an initial address lease from a DHCP server, why is the DHCPREQUEST message sent as a broadcast?
The client may have received offers from multiple servers, and the broadcast serves to implicitly decline those other offers.
After booting, a client receives an ICMPv6 RA message with the M flag set to 0 and the O flag set to 1. What does this indicate?
The client should automatically configure an IPv6 address and then contact a DHCPv6 server for more information.
Refer to the exhibit. What is the cause of the error that is displayed in the configuration of inter-VLAN routing on router CiscoVille?
The encapsulation dot1Q 20 command has not been configured.

What is a possible cause?
The ip helper-address command is missing.
Refer to the exhibit. PC-A is unable to receive an IPv6 address from the stateful DHCPv6 server. What is the problem?
