CHAPTER - 9
1 A technician is unsuccessful in establishing a
console session between a PC and a Linksys integrated router. Both devices have
power, and a cable is connected between them. Which two troubleshooting steps
could help to diagnose this problem? (Choose two.)
#Ensure the correct cable is used.
#Ensure the link status LED on the integrated router is lit.
2 Identify two physical-layer network problems. (Choose two.)
#hardware failure
#loose cable connections
3 Only one workstation on a particular network cannot reach the Internet. What is the first troubleshooting step if the divide-and-conquer method is being used?
#Check the workstation TCP/IP configuration.
4 Which two troubleshooting techniques are suitable for both home networks and large corporate networks? (Choose two.)
#documenting the troubleshooting process
#keeping a record of system upgrades and software versions
5 What two items could be checked to verify connectivity between the router and the ISP? (Choose two.)
#router status page
#connectivity status as indicated by LEDs
6 When acting as a DHCP server, what three types of information can an ISR provide to a client? (Choose three.)
#default gateway
#dynamic IP address
#DNS server address
7 A customer called the cable company to report that the Internet connection is unstable. After trying several configuration changes, the technician decided to send the customer a new cable modem to try. What troubleshooting technique does this represent?
#substitution
8 Which troubleshooting method begins by examining cable connections and wiring issues?
#bottom-up
9 What command is used to determine the location of delay for a packet traversing the Internet?
#tracert
10 A technician suspects that a Linksys integrated router is the source of a network problem. While troubleshooting, the technician notices a blinking green activity LED on some of the ports. What does this indicate?
#The ports are operational and are receiving traffic.
11 Which three settings must match on the client and access point for a wireless connection to occur? (Choose three.)
#SSID
#authentication
#encryption key
12 What should a network administrator do first after receiving a call from a user who cannot access the company web server?
#Ask the user what URL has been typed and what error message displays.
13
Refer to the graphic. What configuration is incorrect in the network shown?
#The wired connection is the wrong type of cable.
14 A technician is troubleshooting a security breach on a new wireless access point. Which three configuration settings make it easy for hackers to gain access? (Choose three.)
#broadcasting the SSID
#using open authentication
#using the default internal IP address
15
Refer to the graphic. What configuration is incorrect in the network shown?
#The host IP address is incorrect.
16 Typically, help desk personnel assist end users in which two tasks? (Choose two.)
#identifying when the problem occurred
#implementing the solution to the problem
17 Network baselines should be performed in which two situations? (Choose two.)
#after the network is installed and running optimally
#after major changes are implemented on the network
18 Which two items should be added to the documentation following a troubleshooting event? (Choose two.)
#final resolution
#results of successful and unsuccessful troubleshooting steps
19 A PC is plugged into a switch and is unable to connect to the network. The UTP cable is suspected. What could be the problem?
#A crossover cable is being used.
20 Which ipconfig command requests IP configuration from a DHCP server?
#ipconfig /renew
21
Refer to the graphic. The wireless host cannot access the Internet, but the wired host can. What is the problem?
#The host WEP key is incorrect.
22 How does remote-access software help in the troubleshooting process?
#Diagnostics can be run without a technician being present at the site.
23 What command is used to determine if a DNS server is providing name resolution?
#nslookup
#Ensure the correct cable is used.
#Ensure the link status LED on the integrated router is lit.
