## Test : CompTIA Network+ (N10-007)

##### What is the correct color scheme for Pin 1 to Pin 8 for a T-568A connector?

Options are :

• blue, white/blue, orange, white/brown, brown, white/green, green, orange/white
• white/green, green, orange/white, blue, white/blue, orange, white/brown, brown (Correct)
• white/orange, orange, white/green, blue, white/blue, green, white/brown, brown
• white/green, green, white/orange, orange, blue, white/blue, white/brown, brown

Answer : white/green, green, orange/white, blue, white/blue, orange, white/brown, brown

Explanation You need to have the T-568-A and T-568-B standards memorized before test day, because you may be asked to perform a drag and drop exercise of placing the right colored wires into the right pin numbers based on a T-568A or T-568B connector.

• white/orange, orange, white/green, blue, white/blue, green, white/brown, brown (Correct)
• white/green, green , white/orange, orange, blue, white/blue, white/brown, brown

Answer : white/orange, orange, white/green, blue, white/blue, green, white/brown, brown

Explanation You need to have the T-568-A and T-568-B standards memorized before test day, because you may be asked to perform a drag and drop exercise of placing the right colored wires into the right pin numbers based on a T-568A or T-568B connector.

##### A customer's email service is not sending emails anymore. What is the correct order that you should follow to perform the troubleshooting steps?

Options are :

• Implement the solution; Verify full system functionality; Establish a theory of probable cause; Determine if any recent changes have been made to the server; Document findings, actions, and outcomes; Establish a plan of action to resolve the problem; Test the theory to determine cause; Implement preventative measures
• Determine if any recent changes have been made to the server; Establish a theory of probable cause; Test the theory to determine cause; Establish a plan of action to resolve the problem; Implement the solution; Verify full system functionality; Implement preventative measures; Document findings, actions, and outcomes (Correct)
• Determine if any recent changes have been made to the server; Document findings, actions, and outcomes; Establish a plan of action to resolve the problem; Test the theory to determine cause; Implement preventative measures; Implement the solution; Verify full system functionality; Establish a theory of probable cause

Answer : Determine if any recent changes have been made to the server; Establish a theory of probable cause; Test the theory to determine cause; Establish a plan of action to resolve the problem; Implement the solution; Verify full system functionality; Implement preventative measures; Document findings, actions, and outcomes

Explanation You must know the CompTIA troubleshooting steps in the right order for the exam. You will see numerous questions both in the multiple-choice and simulation sections on this topic. If you received this question in the simulation section, it will appear as a "drag and drop", with each of the steps making up a single box, and you need to put them into the correct order.

##### Your company has purchased a new building down the street for its executive suites. You have been asked to choose the best encryption for AP4 and AP5 in order to establish a secure wireless connection between the main building and the executive suites. Larger imageChoose the BEST encryption from the options below to maximize security.

Options are :

• Open
• WEP
• WPA
• WPA2-CCMP (Correct)
• WPA2-TKIP

Explanation WPA2-CCMP is the latest wireless security standard and provides the best security protection for wireless networks.

##### Your company has purchased a new building down the street for its executive suites. You have been asked to choose the BEST encryption for AP1, AP2, and AP3 in order to establish a wireless connection inside the main building for visitors to use. Your boss has stated that the internal wireless network in the main building is for visitors' use only and MUST NOT require the visitors to setup any special configuration on their devices in order to connect.Larger imageChoose the BEST encryption from the options below to meet your manager's requirements for the visitors' Wireless Network.

Options are :

• Open (Correct)
• WEP
• WPA
• WPA2-CCMP
• WPA-TKIP

Explanation Since your boss dictated that the visitors MUST NOT be required to configure their devices with any special configuration (this includes a password), you must choose OPEN (no encryption) for the visitors' network.

##### What type of cable would you use to connect a switch to a hub?Larger image

Options are :

• Crossover (Correct)
• RG-6
• Rollover
• RS-232
• Straight-through

Explanation When connecting a switch to a hub, you can use a crossover cable (unless they support MDIX).

##### What ports do SMTP and SNMP utilize?

Options are :

• 23, 25
• 161, 443
• 445, 3389
• 25, 161 (Correct)

Explanation SMTP (Simple Mail Transfer Protocol) uses port 25. SNMP (Simple Network Management Protocol) uses port 161.

##### What ports do HTTPS and RDP utilize?

Options are :

• 443, 25
• 443, 161
• 443, 3389 (Correct)
• 443, 445

Explanation HTTPS (Hyper Text Transfer Protocol Secure) uses port 443. RDP (Remote Desktop Protocol) uses port 3389.

##### You are a network administrator troubleshooting an issue with a newly-installed web server. The web server is available to internal network users, but users from outside the internal network (Internet users) cannot reach the server. You run an IPCONFIG and receive the configuration below:IP               192.168.0.10Netmask     255.255.255.0Gateway     192.168.0.2DNS            10.10.0.254What is the MOST LIKELY reason why the server is unreachable from the Internet?

Options are :

• The configured DNS server is not reachable by the web server.
• The gateway IP has been configured incorrectly.
• The Layer 3 switch port connecting the web server is blocking port 80.
• NAT has not been configured on the border firewall. (Correct)

Answer : NAT has not been configured on the border firewall.

Explanation The most likely cause is that the NAT has not been configured on the border firewall properly. This would cause the internal network users to still be able to access the web servers (since internal traffic doesn't have to transit the firewall), but would still prevent the Internet users from accessing the web server.

##### You are a network administrator who is testing a cable you found in your network closet. You connect a cable tester to both sides of the cable to verify the pinout of the Ethernet cable. After testing each pin, your cable tester gives you the following output:Larger imageBased on this output, what kind of cable did you test?

Options are :

• Patch cable
• Crossover cable (Correct)
• Rollover cable
• RG-6 cable

Explanation This is a crossover cable, as indicated by the reversing of the Tx and Rx pins (pins 1, 2, 3, and 6).

Options are :

• 75.119.217.111
• 75.119.217.112
• 75.119.217.127 (Correct)
• 75.119.217.128
