• Question 441:

  Joe, a technician, is attempting to connect two hubs to add a new segment to his local network. He uses one of his CAT5 patch cables to connect them; however, he is unable to reach the new network segment from his workstation. He can only connect to it from a workstation within that segment. Which of the following is MOST likely the problem?

  A. One of the hubs is defective.
  B. The new hub is powered down.
  C. The patch cable needs to be a CAT6 patch cable.
  D. The technician used a straight-through cable.
  D. The technician used a straight-through cable.

• Question 442:

  A technician is asked to filter inbound and outbound traffic of a specific service on the network. Which of the following would BEST allow the technician to comply with the request?

  A. MAC filtering
  B. IP filtering
  C. Port filtering
  D. Content filtering
  C. Port filtering

• Question 443:

  A user is trying to connect to the wireless network in the office but is unable to establish a consistent connection. The computer alternates connecting between several similarly configured access points. Which of the following would be the BEST way to address this issues?

  A. Adjust the signal strength of the access points with minimal coverage overlap.
  B. Increase the pool in each of the access points to avoid running out of IPs.
  C. Configure each access point to use a different method of encryption than the others.
  D. Reconfigure each of the access points so that they broadcast different SSIDs.
  A. Adjust the signal strength of the access points with minimal coverage overlap.

• Question 444:

  Which of the following would the telecommunications carrier use to segregate customer traffic over long fiber links?

  A. VLAN
  B. MPLS
  C. VPN
  D. PSTN
  B. MPLS

  ---

  MPLS is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links (paths) between distant nodes rather than endpoints

• Question 445:

  Which of the following WAN technologies has a MAXIMUM speed of 155.52Mbps?

  A. OC-3
  B. T3
  C. OC-12
  D. E1
  A. OC-3

• Question 446:

  A customer is having problems connecting to a wireless network in a shared office space. The customer can detect several other wireless network signals. All of the wireless networks have different SSIDs but several are using the same encryption type. Which of the following should be configured on the customer's wireless network to improve connectivity to the wireless network?

  A. Change the SSID to match other wireless networks for increased throughput.
  B. Change the encryption type to a different mechanism to avoid interference.
  C. Change the channel to a different channel than the other wireless networks.
  D. Change the WAP to a different manufacturer than the other wireless networks.
  C. Change the channel to a different channel than the other wireless networks.

  To reduce interference between wireless APs, ensure that wireless APs with overlapping signals use unique channel frequencies. The 802.11b standard reserves 14 frequency channels for use with wireless APs. You can use any other channel instead of the one that you are using.

• Question 447:

  Which of the following layers of the OSI model is responsible for stripping the TCP port information before sending the packet up to the next layer?

  A. 2
  B. 3
  C. 4
  D. 5
  C. 4

• Question 448:

  At which of the following layers of the OSI model do packets exist?

  A. Network
  B. Session
  C. Data Link
  D. Transport
  A. Network

• Question 449:

  The TCP/IP application layer contains which of the following OSI layers?

  A. Layers 1, 5, 6, 7
  B. Layers 4, 7
  C. Layers 5, 6, 7
  D. Layer 7
  C. Layers 5, 6, 7

• Question 450:

  Which of the following will allow a technician to monitor all network traffic when connected to a mirror port?

  A. VLAN tags
  B. SNMP
  C. Packet sniffer
  D. Syslog
  C. Packet sniffer

  ---

  Mirror port just send the packet to the port which is selected to grab the packet of any destination port to capture that packets we need packet sniffer.
