CompTIA N10-006 Online Questions & Answers

• Question 111:

  A network engineer has been tasked with designing a network for a new branch office with approximately 50 network devices. This branch office will connect to the other offices via a MAN. Many of the other branch offices use off-the-shelf SOHO equipment. It is a requirement that the routing protocol chosen use the least amount of overhead. Additionally, all computers on the network will be part of a single VLAN. The connection between these computers should produce the highest throughput possible, in the most cost effective manner. Which of the following devices would be MOST appropriate?

  A. A router should be used as a gateway device, with RIPv2 as the routing protocol. The computers should be connected to one another with a Gb Layer 2 switch.
  B. A UTM should be used as a gateway device, with BGP as the routing protocol. The computers should be connected to one another using 1Gb Fibre Channel.
  C. A router should be used as a gateway device, with EIGRP as the routing protocol. The computers should be connected to one another using a single 802.11N MIMO access point.
  D. A router should be used as a gateway device, with OSPF as the routing protocol. The computers should be connected to one another using a Gb Layer 3 switch.
  A. A router should be used as a gateway device, with RIPv2 as the routing protocol. The computers should be connected to one another with a Gb Layer 2 switch.

  A Gb Layer 2 switch is the cheapest switching solution offering 1Gbps network connectivity between the computers. RIPv2 has a lower overhead as required in the question.

• Question 112:

  A customer has not been using security on a wireless network and has recently received many attacks through this vector.

  Which of the following would be the MOST secure way to harden this wireless network?

  A. Disable the SSID
  B. WPA encryption
  C. VLAN implementation
  D. WEP encryption
  B. WPA encryption

• Question 113:

  A technician is in a large room that contains a large amount of industrial equipment. The technician would like to record the usable bandwidth between devices in a wireless network and the access point. Which of the following should the technician document?

  A. Goodput
  B. EMI
  C. Latency
  D. Jitter
  E. Overhead
  A. Goodput

• Question 114:

  Which of the following networking devices can exist at several layers of the OSI model at the same time? (Select TWO).

  A. Switch
  B. Cable
  C. Repeater
  D. Router
  E. Bridge
  F. Hub
  A. Switch
  D. Router

  ---

  Explanation Explanation/Reference:A Multilayer Switch and Router work from OSI layer 2, 3 or 4 to IP DSCP (if IP packet) and/or VLAN IEEE 802.1p.

• Question 115:

  A desktop computer is connected to the network and receives an APIPA address but is unable to reach the VLAN gateway of 10.10.100.254. Other PCs in the VLAN subnet are able to reach the Internet. Which of the following is MOST likely the source of the problem?

  A. 802.1q is not configured on the switch port
  B. APIPA has been misconfigured on the VLAN
  C. Bad SFP in the PC's 10/100 NIC
  D. OS updates havenot been installed
  A. 802.1q is not configured on the switch port

  ---

  APIPA addresses are self-configured and are used when the client is unable to get proper IP configuration from a DHCP server. One possible source of this problem is that switch port, to which the computer is connected, is misconfigured. The 802.1q protocol is used to configure VLAN trunking on switch ports.

• Question 116:

  A technician is configuring mobile devices for new employees.

  Which of the following documents should be updated to show that the new employees are receiving these mobile devices?

  A. Network diagram
  B. Asset management
  C. Organizational chart
  D. Standard operating procedure
  E. Change management
  B. Asset management

• Question 117:

  Which of the following allows for spatial reuse and utilizes several multipath distortions as RF data streams?

  A. Omni-directional
  B. MIMO
  C. Distributed
  D. Beam forming
  A. Omni-directional

• Question 118:

  A technician working for a company with a wireless network named WirelessA notices a second wireless network named WirelessB. WirelessB is MOST likely a:

  A. man-in-the-middle attack
  B. rogue access point
  C. evil twin
  D. packet sniffer
  B. rogue access point

  ---

  Explanation Explanation/Reference:A rogue access point is a wireless access point that has either been installed on a secure company network without explicit authorization from a local network administrator, or has been created to allow a hacker to conduct a man-in-themiddle attack.

• Question 119:

  A network administrator is configuring one distribution and five access switches, which will be installed in a new building. Which of the following is the BEST physical location for the equipment?

  A. The distribution switch in the IDF and the access switches in the MDF
  B. The distribution switch in the MDF and the access switches in the IDF
  C. All switches should be placed in the IDF to leave room in the MDF for servers
  D. All switches should be placed in the MDF to leave room in the IDF for servers
  B. The distribution switch in the MDF and the access switches in the IDF

• Question 120:

  Which of the following can use a third party back-end LDAP user database for authentication?

  A. ISAKMP
  B. TACACS+
  C. PKI
  D. CHAP
  B. TACACS+
