CompTIA N10-005 Online Questions & Answers

• Question 241:

  Users at a remote site are unable to establish a VPN to the main office. At which of the following layers of the OSI model does the problem MOST likely reside?

  A. Presentation
  B. Application
  C. Physical
  D. Session
  D. Session

• Question 242:

  Ann, a technician, installs a new WAP and users are able to connect; however, users cannot access the Internet. Which of the following is the MOST likely cause of the problem?

  A. The signal strength has been degraded and latency is increasing hop count.
  B. An incorrect subnet mask has been entered in the WAP configuration.
  C. The signal strength has been degraded and packets are being lost.
  D. Users have specified the wrong encryption type and routes are being rejected.
  B. An incorrect subnet mask has been entered in the WAP configuration.

  ---

  Due to wrong subnet entered user is unable to communicate with anyone so to communicate he needs to be in right subnet.

• Question 243:

  A technician sets up a network with multiple WAN connections, backup power sources, multiple firewalls, and a mesh configuration for network switching. All of the software and hardware has fault detection designed to provide a system with minimal down time.

  Which of the following is the BEST example of this optimization method?

  A. Load balancing
  B. High availability
  C. Caching engines
  D. Quality of Service
  B. High availability

• Question 244:

  A technician is attempting to set up a new laptop for a user. The user's old laptop connects to the corporate wireless network "CompanyWiFi" automatically.

  However, when the technician looks for the "CompanyWiFi" network on the new laptop, he does not find it in the list of available networks. Both laptops have 802.11g wireless network adapters and are sitting next to each other on the user's

  desk.

  Which of the following would MOST likely be the reason that the new laptop cannot see the "CompanyWiFi" network?

  A. Loss of signal strength
  B. Incorrect WEP key was input
  C. RFID interference from other electronic devices
  D. SSID broadcasting is disabled on the WAP
  D. SSID broadcasting is disabled on the WAP

• Question 245:

  A technician notices a newly installed CAT5 cable is longer than the standard maximum length. Which of the following problems would this MOST likely cause?

  A. Split cable
  B. EMI
  C. DB loss
  D. Crosstalk
  C. DB loss

  ---

  The maximum length for a cable segment is 100 m per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100metre length between active devices. This allows for 90metres of solid-core permanent wiring, two connectors and two stranded patch cables of 5metres, one at each end.

• Question 246:

  A technician installs a wireless router on an existing network by connecting it directly to the firewall. By default, the main network is a Class A network, while the wireless network is a Class C network. After the wireless router is installed, users connected to the wireless network report they are unable to connect to the Internet.

  Which of the following needs to be configured to BEST resolve this issue?

  A. Configure the main network to Class C
  B. Allow for duplicate IP addresses
  C. Allow the main network to handle DHCP
  D. Create a spanning tree to prevent switching loops
  C. Allow the main network to handle DHCP

• Question 247:

  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 248:

  Which of the following is the difference between 802.11b and 802.11g?

  A. Distance
  B. Frequency
  C. Speed
  D. Transmission power
  C. Speed

  ---

  802.11b has a maximum speed of 11Mbps whereas 802.11g has a speed of 54Mbps.

• Question 249:

  An organization finds that most of the outgoing traffic on the network is directed at several Internet sites viewed by multiple computers simultaneously. Which of the following performance optimization methods would BEST alleviate network traffic?

  A. Load balancing internal web servers
  B. Redundant network resources
  C. Implement fault tolerance on the WAN
  D. Implement caching engines
  D. Implement caching engines

  ---

  A cache server is a dedicated network server or service acting as a server that saves Web pages or other Internet content locally. By placing previously requested information in temporary storage, or cache, a cache server both speeds up access to data and reduces demand on an enterprise's bandwidth.

• Question 250:

  Which of the following defines a rack located in an office building between the main rack and other office equipment?

  A. DSU
  B. MDF
  C. CSU
  D. IDF
  D. IDF

  ---

  An intermediate distribution frame (IDF) is a distribution frame in a central office or customer premises, which cross-connects the user cable media to individual user line circuits and may serve as a distribution point for multipair cables from the main distribution frame (MDF) or combined distribution frame (CDF) to individual cables connected to equipment in areas remote from these frames.

  IDFs are used for telephone exchange central office, customer-premise equipment, wide area network (WAN), and local area network (LAN) environments, among others.
