2What is an example of a dedicated point-to-point WAN link?
3 What are three features of the TCP protocol? (Choose three.)It provides retransmission of data packets if they are lost during transmission.
It is a connectionless protocol.It uses a three-way handshake between the sending and receiving systems to establish each conversation.It specifies how messages are reassembled at the destination host.
It requires only 8 bytes of overhead.
It breaks the data packet into datagrams.
4What is used by a routing protocol to determine the best path to include in the routing table?
Refer to the exhibit. R1 and R2 are configured with the commands that are displayed. All interfaces are properly configured, but neither router is receiving routing updates. What two things can be done to solve the problem? (Choose two.)
Configure the routing protocol on R1 for network 10.0.0.0.
Configure the routing protocol on R2 for network 10.0.0.0.
Configure the routing protocol on R1 for network 192.168.4.0.
Configure the routing protocol on R1 for network 192.168.2.0.
Configure the routing protocol on R2 for network 192.168.1.0.
Configure the routing protocol on R2 for network 192.168.3.0.
6A small tire retailer requires a low-cost WAN connection to its headquarters in order to manage its inventory and process customer sales in real time. Which WAN connection type is best suited to its needs?
Refer to the exhibit. Router Left is unable to ping router Right. The show interfaces serial 0/0/0 command indicates that the interface is up but the line protocol is down on both routers. Which action could be taken to establish connectivity between the two routers?
Configure S0/0/1 instead of S0/0/0 on router Right.
Enter the encapsulation hdlc command on router Right.Contact the service provider to report that the circuit is down.
Contact the service provider to enable PPP on the WAN circuit.
Enter the no encapsulation ppp command on router Left S0/0/0.
8A user reports being able to access the Internet but not being able to download e-mail from the mail server at the ISP. What should the user check on the user workstation?
the POP3 and SMTP server settings in the e-mail application
the patch cable connections at the back of the workstation and at the wall plate
the DHCP settings in the operating system
the IP address, mask, and default gateway values
the NIC drivers
9 What is the primary function of the NOC at a large ISP?installing equipment at a customer site
setting up customer accounts and passwords
monitoring and testing customer network connections
entering customer requirements in an order-tracking database
10A network technician wants to restore a backup copy of the saved configuration file on a router from a TFTP server. After restoring the file from the TFTP server, the technician reloads the router and finds that it still has the old configuration file instead of the restored file. What could have caused this?
The technician entered the command delete flash: before reloading the router.
The technician entered the command boot system rom before reloading the router.
The technician entered the command erase startup-config before reloading the router.The technician failed to enter the command copy running-config startup-config before reloading the router.
Refer to the exhibit. A technician uses the SDM application to configure router R1. Which step should be taken by the technician to enable the Fa0/0 interface on R1 to participate on the connected local network?
Enable a DHCP server on the Fa0/0 LAN interface.
Configure the appropriate IP address on the Fa0/0 interface.
Configure IP addresses for the primary and secondary DNS server.Configure the starting and ending IP addresses for the DHCP pool but exclude the Fa0/0 IP address.
The show ip route command was executed on one of the routers shown in the graphic and the following output was displayed:
C 192.168.4.0/24 is directly connected, Serial0/0R 192.168.5.0/24 [120/1] via 192.168.4.2, 00:00:19, Serial0/0R 192.168.1.0/24 [120/2] via 192.168.3.1, 00:00:20, Serial0/1R 192.168.2.0/24 [120/2] via 192.168.3.1, 00:00:20, Serial0/1C 192.168.3.0/24 is directly connected, Serial0/1
From which router was this command executed?A

Refer to the exhibit. The network administrator uses the command below to configure a default route on RTB:
RTB(config)# ip route 0.0.0.0 0.0.0.0 fa0/0
A ping issued from PC3 is successful to RTB. However, echo request packets arrive at PC1 but the echo replies do not make it back to PC3. What will fix this problem?
RTA must be configured to forward packets to the 192.168.2.0 network.
The ip route command needs to be edited so that the next hop address is 10.1.1.5.The ip route command needs to be edited so that the 192.168.2.1 address is the next hop address.The ip route command should be removed from the RTB router configuration.
Another default route should be configured on RTA with a next hop address of 10.1.1.6.
24
Refer to the exhibit. While configuring the serial interface of a router, the network administrator sees the highlighted error message. What is the reason for this?
The serial interface is administratively down.
The serial interface is already configured with an IP address.The network administrator has attempted to configure the serial interface with a broadcast address.The same IP address has been configured on another interface.
25Which networking service is used to provide name to IP address mapping?DNS
FTP
NAT
DHCP
26 If the configuration register is currently set to 0x2102, what is the first action that a router will take after the bootstrap program loads successfully?
Refer to the exhibit. Devices need to connect to the file server from remote networks. What method should be used to provide the file server with an IP address to allow these connections?
static NAT
