Which protocol should be used to transfer credit card information from customers to the company web server? FTPS HTTP HTTPS WEP2 TFTP Q.2. Refer to the exhibit. A new branch office has been added to the corporate network and anew router is to be installed to allow branch office users to access the database server at h the serial 0/0/0 interface of the new branch office router be configured to connect to the headquarters router? branch_23(config-if)# ip address branch_23(config-if)# no shutdown branch_23(config-if)# encapsulation hdlc branch_23(config-if)# ip address branch_23(config-if)# no shutdown branch_23(config-if)# encapsulation ppp branch_23(config-if)# no shutdown branch_23(config-if)# encapsulation ppp branch_23(config-if)# ip address branch_23(config-if)# encapsulation ppp branch_23(config-if)# ip address branch_23(config-if)# no shutdown Q.3 Which two commands ensure that any password that permits access to the privileged EXEC mode is not shown in plain text when the configuration files are displayed? (Choose tw Router(config)# enable secret cisco Router(config)# enable cisco Router(config)# encryption-password all Router(config)# enable login encrypted Router(config)# enable password encryption Router(config)# service password-encryption Q.4 A new network is to be configured on a router. Which of the following tasks must be completed to configure this interface and implement dynamic IP routing for the new network? Select the routing protocol to be configured. Assign an IP address and subnet mask to the interface

Page 2 of 10 Update the ip host configuration information with the device name and new interface IP address. Configure the routing protocol with the new network IP address.

2 Page 2 of 10 Update the ip host configuration information with the device name and new interface IP address. Configure the routing protocol with the new network IP address. Configure the routing protocol with the new interface IP address and subnet mask. Configure the routing protocol in use on all other enterprise routers with the new network information. Q.5 How does TCP ensure the reliable transfer of data? If data segments are not received from the source, the destination requests that the segments be resent. If an acknowledgment of the transmitted segments is not received from the destination in a predetermined amount of the time, the source resends the data. TCP uses the SYN-ACK portion of the three-way handshake to ensure that all data has been received The TCP Protocol Interpreter process verifies the transmitted data at source and destination. Q.6 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 task? routable translation dynamic translation static translation port address translation Q.7 What is the most commonly used exterior routing protocol? BGP RIP OSPF EIGRP Q.8 Refer to the exhibit. The network administrator needs to configure the router with a name. Which command will the administrator use to configure the router name? Router# ip hostname Boise Router# enable hostname Boise Router(config-line)# name Boise Router(config)# hostname Boise Router(config)# ip hostname Boise Q.9 Why are port numbers included in the TCP header of a segment? to indicate the correct router interface that should be used to forward a segment to identify which switch ports should receive or forward the segment to determine which Layer 3 protocol should be used to encapsulate the data to enable a receiving host to forward the data to the appropriate application to allow the receiving host to assemble the packet in the proper order Q.10 What is the purpose of the routing process? to encapsulate data that is used to communicate across a network to select the paths that are used to direct traffic to destination networks to convert a URL name into an IP address to provide secure Internet file transfer to forward traffic on the basis of MAC addresses Q.11 Which two statements are true about the use of the debug ip rip command on a Cisco router? (Choose two.) The debug ip rip command displays RIP routing activity in real time. The debug ip rip command can be issued at the user EXEC configuration mode. The debug ip rip command displays a combination of the information that is displayed by the show ip route and show ip protocols commands. Because of router processor usage, the debug ip rip command should be used only when necessary. The debug ip rip command should be used instead of the show ip route command whenever possible. Q.12 What minimum configurations must be set on a host to allow a request to be sent to (Choose four.) DNS server WINS server IP address NetBIOS subnet mask default gateway

What connection is in use? leased line packet switched circuit switched point-to-point Q.20 A user reports being unable to access the Internet. The help desk technician employs a bottom-up approach to troubleshooting. The technician first has the user check the patch c PC to the wall, and then has the user verify that the NIC has a green link light. What will the technician have the user do next? Enter an IP address into the WWW browser address bar to see if DNS is at fault. Use traceroute to identify the device along the path to the ISP that may be at fault. Verify the IP address, subnet, and gateway settings using ipconfig on the PC. Connect to the user home router to check firewall settings for blocked TCP ports. Q.21 A ping command is issued on workstation A to determine if workstation B can be reached. What events will occur if this command is successful? (Choose two.) The router will block the ping request message. The router will reply to the echo request with a proxy ping response. Workstation A will send a UDP ping request message to workstation B. Workstation B will send a UDP ping reply message to workstation A. Workstation A will send an ICMP echo request message to workstation B. Workstation B will send an ICMP echo reply message to workstation A. Q.22 How does a router know of paths to destination networks? (Choose two.) inspection of the destination IP address in data packets ARP requests from connected routers manual configuration of routes updates from other routers DHCP information broadcasts updates from the SMTP management information base Q.23 Refer to the exhibit.

PAT uses the word "overload" at the end of the access-list statement to share a single registered address. Static NAT allows an unregistered address to map to multiple registered addresses. Dynamic NAT allows hosts to receive the same global address each time external access is required. PAT uses unique source port numbers to distinguish between translations.
