Review Notes, v. 3.1 1.1.1 Private addressing 1.1.2 Major NAT and PAT features Dynamic NAT is designed to map a private IP address to a public address. Any IP address from a pool of public IP addresses is assigned to a network host. Overloading, or Port Address Translation (PAT), maps multiple private IP addresses to a single public IP address. Multiple addresses can be mapped to a single address because each private address is tracked by a port number. 1.1.3 Configuring NAT and PAT The access list must permit only those addresses that are to be translated. Remember that there is an implicit “deny all” at the end of each access list. 1.1.4 Configuring DHCP - Typically, a DHCP server will be configured to assign much more than an IP address. Other IP configuration values such as the default gateway can be set from the DHCP configuration mode. Using the default-router command sets the default gateway. - A default router must be defined for clients 2.1.1 WAN devices - For digital lines, a

1. A network administrator is asked to design a system to allow simultaneous access to the Internet for 250 users. The ISP for this network can only supply five public IPs. What can be used to accomplish this task? routable translation dynamic translation static translation • port address translation 2. The LAN attached to the Ethernet interface of the Raleigh router shown in the graphic is addressed with private IP addresses. If one public IP is assigned to the company, which commands could be used in a configuration that allows all devices with private IPs in this network to access the Internet? (Choose two.) • ip nat inside source list 1 interface serial0 overload ip nat outside source list 1 interface serial0 overload ip nat inside serial0 • ip nat inside source list 1 pool Raleigh overload ip nat inside Raleigh overload ip inside nat source list 1 interface serial0 Raleigh 3. The command output shown in the graphic was taken from a Cisco 806 broadband router. Which kind of address

1. Identify the factors that contribute to congestion on an Ethernet LAN. (Choose three.) • improper placement of enterprise level servers • addition of hosts to a physical segment replacement of hubs with workgroup switches • increasing use of bandwidth intensive network applications migration to full-duplex Ethernet within the LAN 2. Which of the following are examples of TCP/IP application layer protocols? (Choose three.) • a terminal emulation protocol that supports remote console connections with various network devices a protocol created by IBM that makes it easier for mainframes to connect to remote offices • a protocol responsible for transporting electronic mail on TCP/IP networks and the Internet a protocol that controls the rate at which data is sent to another computer • a protocol that exchanges network management information between a network device and a management console 3. Which of the following eliminates switching loops? hold-down timers poison reverse • spanning tr

Thanks Khaled ismael. If you have CCNA final exam, please send to me at: nguyenhuuhai.it@gmail.com 1. What are two main components of data confidentiality? (Choose two.)  check sum  digital certificates   encapsulation  encryption  hashing 2. While troubleshooting a problem with an e-mail server, an administrator observes that the switch port used by the server shows "up, line protocol up". The administrator cannot ping the server. At which layer of the OSI model is the problem most likely to be found? application layer network layer data link layer physical layer 3. Which combination of authentication and Layer 2 protocol should be used to establish a link between a Cisco and a non-Cisco router without sending authentication information in plain text? CHAP and HDLC CHAP and PPP PAP and HDLC PAP and PPP 4. An administrator is configuring a dual stack router with IPv6 and IPv4 using RIPng. The administrator receives an error message when trying to enter the IPv4 routes into

1. Refer to the exhibit. A network administrator is trying to configure a router to use SDM. After this configuration shown in the exhibit is applied, the SDM interface of the router is still not accessible. What is the cause of the problem? *The username and password are not configured correctly. The authentication method is not configured correctly. The HTTP timeout policy is not configured correctly. The vtys are not configured correctly. 2. Refer to the exhibit. Branch A has a non-Cisco router that is using IETF encapsulation and Branch B has a Cisco router. After the commands that are shown are entered, R1 and R2 fail to establish the PVC. The R2 LMI is Cisco, and the R1 LMI is ANSI. The LMI is successfully established at both locations. Why is the PVC failing? The PVC to R1 must be point-to-point. LMI types must match on each end of a PVC. The frame relay PVCs cannot be established between Cisco and non-Cisco routers. *The IETF parameter is missing from the frame-relay map ip 10.

1 Which of the following describes the roles of devices in a WAN? (Choose three.) *** A CSU/DSU terminates a digital local loop. A modem terminates a digital local loop. A CSU/DSU terminates an analog local loop. *** A modem terminates an analog local loop. *** A router is commonly considered a DTE device. A router is commonly considered a DCE device. www.p4s-ccna.blogspot.com 2 What value in the address field of a Frame Relay header identifies the destination of the frame? CIR DE *** DLCI ISDN FRAD PVC 3 The serial PPP link between the Left and Right routers is configured as shown in the diagram. Which configuration issue explains why the link is unable to establish a PPP session? The IP addresses must be on different subnets. *** The usernames are misconfigured. The passwords must be different for the CHAP authentication. The clock rate must be 56000. The clock rate is configured on the wrong end of the link. Interface serial 0/0 on Left must connect to interface serial 0/1 on Right.
