CompTIA N10-006 Online Questions & Answers

• Question 1521:

  Which of the following is the BEST way to prevent new users from connecting to a wireless access point, but still allow already connected users to continue to connect?

  A. Create a MAC filter containing the current users.
  B. Turn off SSID broadcast.
  C. Change the encryption type to AES 256-bit for current users.
  D. Reduce the signal strength to 0 percent.
  A. Create a MAC filter containing the current users.

  Explanation Explanation/Reference:MAC Filtering (or EUI filtering, or layer 2 address filtering) refers to a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network.

• Question 1522:

  Which of the following methods would be implemented to correct a network slowdown caused by excessive video streaming?

  A. Traffic shaping
  B. Proxy server
  C. VPN concentrator
  D. High availability
  A. Traffic shaping

  ---

  As traffic shaping will prioritize the video packets over another packets and then video packets will travel fast on bandwidth.

• Question 1523:

  The systems administrator has assigned an IP address and default gateway to a standard Layer 2 switch. Which of the following would be the primary purpose of doing this?

  A. Allow VLAN routing
  B. Enable packet filtering on the switch
  C. Allow remote administration of the switch
  D. Enable MAC filtering on the switch
  C. Allow remote administration of the switch

• Question 1524:

  Which of the following do 802.11 networks use to handle packet collisions from multiple nodes?

  A. CSMA/CA
  B. CSU/DSU
  C. Ethernet Tokens
  D. CSMA/CD
  A. CSMA/CA

• Question 1525:

  A technician recently ran a 20-meter section of CAT6 to relocate a control station to a more central area on the production floor. Since the relocation, the helpdesk has received complaints about intermittent operation. During the troubleshooting process, the technician noticed that collisions are only observed on the switch port during production. Given this information, which of the following is the cause of the problem?

  A. Distance limitation
  B. Electromagnetic interference
  C. Cross talk
  D. Speed and duplex mismatch
  B. Electromagnetic interference

  ---

  Explanation Explanation/Reference:When cables are installed near electrical devices the signal within the cable might become corrupt. The cable connecting the control station to theswitch port is now surrounded by the production machinery. Electromagnetic interference could occur when the machinery is running, causing the intermittent operation. Pass Your Certification With Marks4sure Guarantee 126

• Question 1526:

  Which of the following protocols uses label-switching routers and label-edge routers to forward traffic?

  A. BGP
  B. OSPF
  C. IS-IS
  D. MPLS
  D. MPLS

  ---

  In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. MPLS works by prefixing packets with an MPLS header, containing one or more labels. An MPLS router that performs routing based only on the label is called a label switch router (LSR) or transit router. This is a type of router located in the middle of a MPLS network. It is responsible for switching the labels used to route packets. When an LSR receives a packet, it uses the label included in the packet header as an index to determine the next hop on the label-switched path (LSP) and a corresponding label for the packet from a lookup table. The old label is then removed from the header and replaced with the new label before the packet is routed forward. A label edge router (LER) is a router that operates at the edge of an MPLS network and acts as the entry and exit points for the network. LERs respectively, add an MPLS label onto an incoming packet and remove it off the outgoing packet. When forwarding IP datagrams into the MPLS domain, an LER uses routing information to determine appropriate labels to be affixed, labels the packet accordingly, and then forwards the labelled packets into the MPLS domain. Likewise, upon receiving a labelled packet which is destined to exit the MPLS domain, the LER strips off the label and forwards the resulting IP packet using normal IP forwarding rules.

• Question 1527:

  An administrator is setting up a secure wireless network. The administrator decides to support 802.11n and 802.11g with a WPA2 pre-shared key. Users are given the SSID with the pre-shared key, but the administrator has disabled the SSID broadcast and MAC filtering. Some users have reported connection issues. Which of the following would MOST likely resolve the users' connection issues?

  A. Limit the devices to 802.11n only.
  B. Enable the SSID broadcast.
  C. Enable MAC filtering.
  D. Use a WEP 128-bit key.
  B. Enable the SSID broadcast.

• Question 1528:

  A network technician is designing a SOHO environment where cost is a consideration. The requirements include access to the Internet and access to the guest house which is 100 feet away. The location of the Internet modem is located in the main house. Which of the following is the BEST option to accomplish these requirements?

  A. Use two combined Internet/router/wireless devices, one in each house.
  B. Use a Layer 3 switch in the main house and a combined Internet/router/wireless device in the guest house.
  C. Use a combined Internet/router/wireless device in the main house and a wireless access point in the guest house.
  D. Use a single combined Internet/router/wireless device at the guest house.
  C. Use a combined Internet/router/wireless device in the main house and a wireless access point in the guest house.
