Network+ N10-005 exam the first time you take is practice test questions for your mobile phone or other mobile device. Check it out
here.
1 - Application Layer
Q. Which of the following layers of the TCP/IP model correspond to the Session layer of the OSI model?
A. Network Interface
B. Internet
C. Transport
D. Application
Answer:
D is correct. The Application layer of the TCP/IP model corresponds to the Session, Presentation, and Application layers of the Open Systems Interconnection (OSI) model so the Application layer is the best choice of the available answers.
A is incorrect. The Network Interface layer of the TCP/IP model corresponds to the Physical and Data Link layers of the OSI model.
B is incorrect. The Internet layer of the TCP/IP model corresponds to the Network layer of the OSI model.
C is incorrect. The Transport layer of the TCP/IP model corresponds to the Transport layer of the OSI model.
Objective: 1.1 Compare the layers of the OSI and TCP/IP models.
2 - Incompatible Wireless Standards
Q. You have been asked to assist a small business owner connect his new laptop computer to his existing wireless network. Several computers throughout the location are connecting to the network using 802.11a, but the owner’s new laptop computer cannot connect. What is the most likely reason why?
A. Incompatible standards
B. The WAP is too far away
C. The WAP is set to the wrong frequency
D. The WAP is transferring data too slow at only 11 Mbps
Answer:
A is correct
. 802.11a is an older standard and many wireless systems are not backwards compatible to 802.11a. Based on the symptoms and the available answers, the problem is likely a standard mismatch. For example, the laptop computer could be using 802.11g which uses a frequency of 2.4 GHz instead of 5.0 GHz used by 802.11a.
B is incorrect. Other systems are working within the business location and there is no indication the new laptop is farther away than other systems.
C is incorrect. If other systems are working, the WAP is set to the correct frequency of 5 GHz for 802.11a. However, it’s likely that the laptop is using a newer standard such as 802.11g on 2.4 GHz.
D is incorrect. 802.11a transfers data as fast as 54 Mbps.
Objective: 2.2 Given a scenario, install and configure a wireless network.
3 - 802.11n
Q. Which of the following uses MIMO and OFDM?
A. 802.11a
B. 802.11b
C. 802.11g
D. 802.11n
Answer:
D is correct
. 802.11n uses multiple-input multiple-output (MIMO) technologies and orthogonal frequency-division multiplexing (OFDM). 802.11n is the only one of the listed wireless standards that uses MIMO.
A is incorrect. 802.11a uses OFDM but not MIMO.
B is incorrect. 802.11g uses OFDM and DSSS, but not MIMO.
C is incorrect. 802.11b uses direct-sequence spread spectrum (DSSS), but not MIMO.
Objective: 3.3 Compare and contrast different wireless standards.
4 - Tracert
Q. A technician executed the following command:
tracert darrilgibson.com. What type of information does this provide? (Choose all that apply.)
A. Physical address of systems
B. MAC address of systems
C. IP address for each hop
D. IP address for local system
Answer:
C is correct
. The tracert (or traceroute) command identifies the IP address of each of the hops between two systems. Each hop is a router and the round trip
time (RTT) shows how long it takes to get to and from the two systems. Try it with
tracert GetCertifiedGetAhead.com.
Answer:
D is correct
. The result shows the name and IP address of the local system.
A and B are incorrect. You can identify the physical address or media access control (MAC) address, and the IP address of the local system with the
ipconfig /all command, but not with the tracert command.
Objective: 4.3 Given a scenario, use appropriate software tools to troubleshoot connectivity issues.
5 - WPA and MAC Address Filtering
Q. You are assisting a small business owner secure his wireless network. It is currently using WEP and has three computers that are authorized to connect. Of the following choices, what would provide the best improvement in security?
A. Disable MAC filtering and enable WPA
B. Enable SSID broadcast and use MAC address filtering
C. Change the SSID name from the default and use WEP2
D. Use MAC address filtering and WPA
Answer:
D is correct
. Of the choices given, using media access control (MAC) filtering and Wi-Fi Protected Access (WPA) provides the best security, especially because Wired Equivalent Privacy (WEP) has been cracked. MAC address filtering can be used to restrict access to only the clients with specific MAC addresses (but a dedicated attacker can beat this). WPA security ensures that only clients that have the pre-shared key can connect. WPA2 is preferable over WPA when
available.
A is incorrect. While MAC address filtering can be beaten by a dedicated attacker, having it provides more security than disabling it.
B is incorrect. Manipulating service set identifier (SSID) broadcast provides very little security. It can hide a network from users making it more difficult to
connect, but attackers using a wireless sniffer can still see it.
C is incorrect. Changing the SSID from its default is a good security practice but there is no such thing as WEP2.
Objective: 5.1 Given a scenario, implement appropriate wireless security measures.
