Nguyen Tu Anh - Take Exam Exam questions Time remaining: 00: 09: 32 1 . What command would you use to define a global address pool? ip local-pool ip address-pool ip global-pool ip global pool 2 . When the following configuration is present on the router, how many addresses will be available for dynamic NAT translation? ip nat pool test 192.168.1.33 192.168.1.42 netmask 255.255.255.224 ip nat inside source list 7 pool test 7 9 10 31 3 . What is happening here is that the two hosts are on different networks on other sides of the NAT router. However, both networks happen to be using the same RFC 1918 private network addresses. The NAT router takes the host address 10.0.0.1 from inside my network and translates it to 222.2.2.1. The NAT router takes the host address 10.0.0.1 from outside my network and translates it to 111.1.1.1. So, from this diagram you can see how the Inside Local addresses are addresses inside my network and the Inside Global addresses are translated to addresses outside of my network (and they must be translated back to get back inside my network). The Outside Global addresses are on another network and are legitimate outside of my network. They are translated to Outside Local addresses, which are legitimate inside of my network. When using a Cisco 700 router, a ping from an outside host: will not work with the Cisco 700 router will reach the host destination IP address will end at the router because end-to-end connectivity testing isn’t possible with the Cisco 700 router will loop endlessly 4 . Which command would you use to show and verify NAT configuration and statistics? show ip nat show ip nat translation show nat show nat translation 5 . Which are examples of protocol translation? Choose two. Connect via TN3270, then telnet to the destination Connect to an access server using telnet, then use LAT Connect to an access server using telnet, then use telnet to another host Connect to an access server using PPP, then use CHAP to authenticate 6 . Which of the following services are provided by Cisco NAT? Choose two. Static address translation Domain name resolution IP to MAC address resolution TCP load balancing 7 . Which of the following are disadvantages of NAT (Network Address Translation)? Choose three. Overlap dysfunction Conservation of IP addresses Latency Accountability Functionality 8 . Which two services are available through Cisco NAT? TCP load distribution Domain lookup Address Resolution Static address translation Specific address filtration 9 . What process normally occurs when you use dynamic NAT? Your address is always translated to the same address Your address is dynamically chosen from a pool of available addresses Your address is never translated Your address is always translated to a different address 10 . What usually occurs when you use static NAT? Your IP address is incremented each time Your IP address is always translated to the same address Your IP address is always translated to a different address Your IP address is dynamically chosen through an address pool 11 . What is used in an extended access list but not in a standard access list? Source hostname IP address and subnetmask Destination port information Session layer information Source network IP address and subnetmask 12 . Read and answer the question? A B C D 13 . Which of the following is an example of protocol translation? LAT to Telnet Telnet to Telnet PAP to CHAP Ethernet to IP 14 . What happens when the command “clear ip nat translation *” is entered on a router? Clears all existing NAT translation table entries and NAT is suspended. Clears dynamic NAT translation table entries and NAT resumes. Clears static NAT translation entries and NAT resumes. Clears all inactive NAT translation entries and NAT is suspended. 15 . How does NAT allow for more hosts than there are available IP addresses? Never using the same address twice Modifying TCP port numbers Manipulating the IP authentication field Restricting the number of hosts allowed to communicate on the network simultaneously 16 . Which of the following is an example of Cisco protocol translation? translate ip 172.21.3.4 lat x25 123555222 translate ip lat 172.21.3.4 vax11 translate ip lat 172.21.3.4 x25 1235552222 translate tcp 172.21.3.4 x25 1235552222 17 . Which three functions does PAT provide for Cisco 700 series routers? Address translations Remote host location on behalf of local clients IP address conservation Firewall protection by hiding local clients Downloads configuration to local clients 18 . What are three functions that PAT (Port Address Translation) provides? Address translation IP address conservation Firewall Service IP address resolution 19 . Overload occurs when NAT experiences: No more static address translations Messages too fast for the console to handle More hosts than available addresses Excessive CPU utilization 20 .
