Cisco Interconnecting Cisco Networking Devices Part 1 (ICND1 v3.0)

Question No: 151 – (Topic 4)

What does the quot;Inside Globalquot; address represent in the configuration of NAT?

  1. the summarized address for all of the internal subnetted addresses

  2. the MAC address of the router used by inside hosts to connect to the Internet

  3. a globally unique, private IP address assigned to a host on the inside network

  4. a registered address that represents an inside host to an outside network

Answer: D Explanation:

NAT: Local and Global Definitions http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080094837. shtml

Cisco defines these terms as:

Inside local address-The IP address assigned to a host on the inside network. This is the address configured as a parameter of the computer OS or received via dynamic address allocation protocols such as DHCP. The address is likely not a legitimate IP address assigned by the Network Information Center (NIC) or service provider.

Inside global address-A legitimate IP address assigned by the NIC or service provider that represents one or more inside local IP addresses to the outside world.

Outside local address-The IP address of an outside host as it appears to the inside network. Not necessarily a legitimate address, it is allocated from an address space routable on the inside.

Outside global address-The IP address assigned to a host on the outside network by the host owner.

The address is allocated from a globally routable address or network space.

These definitions still leave a lot to be interpreted. For this example, this document redefines these terms by first defining local address and global address. Keep in mind that the terms inside and outside are NAT definitions. Interfaces on a NAT router are defined as inside or outside with the NAT configuration commands, ip nat inside destination and ip nat outside source . Networks to which these interfaces connect can then be thought of as inside networks or outside networks, respectively.

Local address-A local address is any address that appears on the inside portion of the network.

Global address-A global address is any address that appears on the outside portion of the network.

Question No: 152 – (Topic 4)

The network administrator is using a Windows PC application that is called putty.exe for remote communication to a switch for network troubleshooting. Which two protocols could be used during this communication? (Choose two.)

  1. SNMP

  2. HTTP

  3. Telnet

  4. RMON

  5. SSH

Answer: C,E Explanation:

PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms, and is used to connect to Cisco and other networking devices using SSH or Telnet.

Question No: 153 DRAG DROP – (Topic 4)

Drag the definition on the left to the correct term on the right. Not all definitions on the left will be used.




Question No: 154 – (Topic 4)

What happens when computers on a private network attempt to connect to the Internet through a Cisco router running PAT?

  1. The router uses the same IP address but a different TCP source port number for each connection.

  2. An IP address is assigned based on the priority of the computer requesting the connection.

  3. The router selects an address from a pool of one-to-one address mappings held in the lookup table.

  4. The router assigns a unique IP address from a pool of legally registered addresses for the duration of the connection.

Answer: A

Reference: http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/nat_staticpat.html

Static PAT translations allow a specific UDP or TCP port on a global address to be translated to a specific port on a local address. That is, both the address and the port numbers are translated.

Static PAT is the same as static NAT, except that it enables you to specify the protocol (TCP or UDP) and port for the real and mapped addresses. Static PAT enables you to identify the same mapped address across many different static statements, provided that the port is different for each statement. You cannot use the same mapped address for multiple static NAT statements.

Port Address Translation makes the PC connect to the Internet but using different TCP source port.

Question No: 155 – (Topic 5)




Including the address on the Routed Ethernet interface, how many hosts can have IP addresses on the LAN to which Routed is connected?

  1. 6

  2. 30

  3. 62

D. 126

Answer: A Explanation:

This is a /29 address, so there are 6 usable IP’s on this subnet.

Question No: 156 – (Topic 5)

Refer to the exhibit.


A network administrator has configured a Catalyst 2950 switch for remote management by pasting into the console the configuration commands that are shown in the exhibit.

However, a Telnet session cannot be successfully established from a remote host. What should be done to fix this problem?

  1. Change the first line to interface fastethernet 0/1.

  2. Change the first line to interface vlan 0/1.

  3. Change the fifth line to ip default-gateway

  4. Change the fifth line to ip route

  5. Change the sixth line to line con 0.

Answer: C Explanation:

The default gateway must reside on the same IP subnet as the device. Here, the subnet mask for the VLAN interface is /228. Only choice C will fix this issue, as then the default gateway is on the same subnet as the 2950.

Question No: 157 – (Topic 5)

Refer to the exhibit.


The network administrator made the entries that are shown and then saved the configuration. From a console connection, what password or password sequence is required for the administrator to access privileged mode on Router1?

  1. cisco

  2. sanfran

  3. sanjose

  4. either cisco or sanfran

  5. either cisco or sanjose

  6. sanjose and sanfran

Answer: B Explanation:

The enable secret password takes precedence over the enable password, so sanfran will be used.

Question No: 158 – (Topic 5)

Refer to the exhibit.


A person is trying to send a file from a host on Network A of the JAX Company to a server on Network Z of the XYZ Company. The file transfer fails. The host on Network A can communicate with other hosts on Network A.

Which command, issued from router RTA, would be the most useful for troubleshooting this problem?

  1. show flash:

  2. show history

  3. show version

  4. show interfaces

  5. show controllers serial

Answer: D Explanation:

The most useful thing to check on RTA would be the show interfaces command to see if the interface toward the WAN link is up. The most likely scenario is that the local LAN interface is up, but the other interface toward the XYZ company is down.

Question No: 159 – (Topic 5)



Which of the following is true regarding the configuration of SwitchA?

  1. only 5 simultaneous remote connections are possible

  2. remote connections using ssh will require a username and password

  3. only connections from the local network will be possible

  4. console access to SwitchA requires a password

Answer: B

Question No: 160 – (Topic 5)




What is the subnet broadcast address of the LAN connected to Router1?





Answer: A Explanation:

The IP address assigned to FA0/1 is, making the broadcast address.
