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

• Question 692:

  Which of the following is the radio frequency and data rate for 802.11g as specified by the IEEE standards?

  A. 2.0 GHz at 33 Mbps
  B. 2.4 GHz at 54 Mbps
  C. 2.4 GHz at 128 Mbps
  D. 5.0 GHz at 54 Mbps
  B. 2.4 GHz at 54 Mbps

• Question 693:

  A network technician recently replaced a managed switch in an enterprise network with a new managed switch. Users on the switch can communicate with each other but now cannot access other network segments. Which of the following is the MOST likely reason that the users are unable to access any network segments?

  A. The newly installed switch is defective and must be returned.
  B. The newly installed switch is using a different MAC address than the previous switch.
  C. The technician forgot to change the VTP mode on the new switch to server.
  D. The technician did not use the correct cable when trunking the new switch.
  D. The technician did not use the correct cable when trunking the new switch.

• Question 694:

  In contrast to earlier Wi-Fi speeds, which of the following BEST describes the antenna and channelization properties used in 802.11n?

  A. MIMO, DSSS
  B. MIMO, OFDM
  C. CSMA, DSSS
  D. CSMA, CDMA
  B. MIMO, OFDM

  ---

  802.11n builds upon previous 802.11 standards by adding multiple-input multiple- output (MIMO). The additional transmitter and receiver antennas allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity through coding schemes like Alamouti coding. The speed is 150 Mbit/s (even 250 Mbit/s in PHY level)

• Question 695:

  A network technician has a RADIUS server IP address that must be included as part of the security settings for a WAP. Which of the following encryption types should the technician select?

  A. WPA enterprise
  B. TKIP
  C. WPA2 CCMP
  D. WEP 128-bit
  A. WPA enterprise

• Question 696:

  In the event of a fire in an office building, which of the following cable types should be installed to prevent toxic gas from burning PVC cable coatings?

  A. CAT6a
  B. Plenum
  C. Crossover
  D. STP
  B. Plenum

• Question 697:

  Which of the following port numbers is used for SNMP?

  A. 61
  B. 151
  C. 161
  D. 1611
  C. 161

  Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks". Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, UPSes and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.

• Question 698:

  Which of the following describes the amount of time it takes for a packet to transmit from one switch to another?

  A. Hop count
  B. Latency
  C. MTU limit
  D. Distance vector
  B. Latency

• Question 699:

  An administrator would like to inspect all traffic flowing over the SMTP protocol on a given network. Which of the following tools would accomplish this? (Select TWO).

  A. Packet sniffer
  B. Honeypot
  C. Port mirroring
  D. IPS
  E. Port scanner
  F. IDS
  A. Packet sniffer
  C. Port mirroring

  (IPS), also known as intrusion detection and prevention systems (IDPS), are network security appliances that monitor network and/or system activities for malicious activity. The main functions of intrusion prevention systems are to identify malicious activity, log information about this activity, attempt to block/stop it, and report it. And we use packet sniffer to detect the types of packet.

• Question 700:

  A technician has installed a group of layer 2 switches with multiple VLANs. The VLANs cannot talk to each other. Which of the following network devices could correct this problem? (Select TWO).

  A. Hub
  B. DNS server
  C. DHCP server
  D. Layer 3 switch
  E. Router
  D. Layer 3 switch
  E. Router
