CompTIA N10-006 Online Questions & Answers

• Question 151:

  Users report that they are unable to access any external websites. The local intranet is not affected. A network technician has isolated the problem to a Linux- based server. Which of the following commands will enable the technician to view DNS information on the Linux-based server?

  A. nbtstat
  B. ipconfig
  C. dig
  D. netstat
  C. dig

  ---

  By dig command technician will come to know wheather name resolution is happening in correc way or not.

• Question 152:

  A network technician performs several switch commands to enable various advanced features on the switch in the accounting department. During the configuration changes, several users from this department report connectivity issues. Which of the following logs would the network technician need to analyze to troubleshoot the connectivity issues?

  A. Router logs
  B. History logs
  C. Startup/bootup config logs
  D. Event Viewer logs
  B. History logs

• Question 153:

  A network technician needs to configure a port on a switch to provide connectivity and electrical support to a WAP being installed in a warehouse. Which of the following features needs to be configured on the switch?

  A. STP
  B. PoE
  C. VTP trunking
  D. Port forwarding
  B. PoE

  ---

  Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras.

• Question 154:

  A user is connecting to the Internet at an airport through an ad-hoc connection. Which of the following is the MOST likely security threat?

  A. Man-in-the-middle
  B. Social engineering
  C. Phishing
  D. DoS
  A. Man-in-the-middle

  ---

  A man in the middle attack is one in which the attacker intercepts messages in a public key exchange and then retransmits them, substituting his own public key for the requested one, so that the two original parties still appear to be communicating with each other.

• Question 155:

  A user reports sporadic network outages. The user tells the administrator it happens after approximately 20 minutes of work on an application. The administrator should begin troubleshooting by checking which of the following?

  A. The IDS server logs
  B. The DNS resolution time
  C. The firewall's blocked logs
  D. The patch cable
  D. The patch cable

• Question 156:

  A recent flood in the office caused a lot of equipment to be damaged and the manager of the IT department would like a way to prevent such an incident in the future. Which of the following is the BEST way to mitigate such an equipment failure?

  A. Reduce the power input on the replacement servers.
  B. Cover the servers with plastic tarps.
  C. Purchase twice as many servers to create high availability clusters.
  D. Transfer the replacement servers offsite to a data center.
  D. Transfer the replacement servers offsite to a data center.

  ---

  Explanation Explanation/Reference:As we replace replacement servers offsite to datacenter this will cause lower traffic on over lan and will not cause failure of these server also.

• Question 157:

  An administrator is receiving reports from an executive that the executive's wireless access point loses the signal frequently, even though the WAP is on the executive's desk. The office contains four other 802.11n access points. Which of the following would MOST likely correct interference problems in the executive's office?

  A. Turn off SSID broadcasting for the executive's access point
  B. Replace the 802.11n access point in the office with an 802.11a access point.
  C. Change the channel on the access point to channel 11.
  D. Turn off as many lights in the executive's office as possible to reduce interference.
  C. Change the channel on the access point to channel 11.

• Question 158:

  Which of the following security devices can receive and process HTTP requests from hosts to allow or deny traffic for web browsing purposes only?

  A. Load balancer
  B. VPN concentrator
  C. Proxy server
  D. DNS server
  C. Proxy server

• Question 159:

  Which of the following features will a firewall MOST likely use to detect and prevent malicious traffic on the network?

  A. Zone filtering
  B. Signature identification
  C. Port identification
  D. Port scanner
  B. Signature identification

  ---

  Explanation Explanation/Reference:Signature-based detection really is more along the lines of intrusion detection than firewalls. However, many personal firewalls and some corporate firewalls contain this functionality. Essentially, the system can be configured to look for specific patterns, known to be malicious, and block the traffic

• Question 160:

  A network technician is troubleshooting connectivity problems between switches but suspects the ports are not properly labeled. Which of the following options will help to quickly identify the switches connected to each port?

  A. Configure TACACs+ on each network device.
  B. Enable a discovery protocol on the network devices.
  C. Configure each uplink to send LACP discovery units.
  D. Enable a packet sniffer on each network device's uplink port.
  B. Enable a discovery protocol on the network devices.

  "Neighbor discovery protocols are essential for network administrators and management tools to accurately construct a view of the network topology. Each manufacturer has its own supported mix of neighbor discovery protocols, loosely based on how standards-focused that vendor is and how much it wants to pay in royalties to use proprietary protocols. The two most widely used are LLDP (Link Layer Discovery Protocol), an IEEE standard, and CDP (Cisco Discovery Protocol)."
