  A. Virtual desktops
  B. Virtual servers
  C. NaaS
  D. SaaS
  C. NaaS

• Question 112:

  A user informs the network administrator of increasingly common wireless connection problems. The administrator determines the user has recently received a new cordless phone. The phone is MOST likely causing which of the following conditions?

  A. Signal strength latency
  B. Bouncing signal
  C. Interference
  D. Crosstalk
  C. Interference

• Question 113:

  Which of the following uses port 23 by default?

  A. TELNET
  B. IMAP
  C. FTP
  D. SNMP
  A. TELNET

  ---

  Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).

• Question 114:

  Which of the following security protocols would BEST protect a connection to a remote email server and ensure full integrity of all transmitted email communication?

  A. TLS 1.2
  B. SNMPv3
  C. WPA2
  D. SMTP
  A. TLS 1.2

• Question 115:

  Which of the following is the MAXIMUM rated speed for CAT5 cabling?

  A. 10Mbps
  B. 100Mbps
  C. 1000Mbps
  D. 10Gbps
  B. 100Mbps

  ---

  Category 5 cable (Cat 5) is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. The cable standard provides performance of up to 100 MHz and is suitable for 10BASE- T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet)

• Question 116:

  Frame relay occurs at which of the following layers of the OSI model?

  A. Layer 1
  B. Layer 2
  C. Layer 4
  D. Layer 6
  B. Layer 2

• Question 117:

  A technician has a network with a mix of newer and older equipment. Which of the following settings would dynamically configure whether to use full or half duplex?

  A. Transmission speed
  B. Frequency
  C. Auto-negotiate
  D. Distance
  C. Auto-negotiate

  ---

  Autonegotiation is an Ethernet procedure by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest performance transmission mode they both support.

• Question 118:

  CAT6 has how many twisted copper pairs?

  A. 2
  B. 4
  C. 6
  D. 8
  E. 16
  B. 4

• Question 119:

  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 120:

  Ann, a client, shares half of a rectangular floor plan with another company and wishes to set up a secure wireless network. The installed antenna limits the signal to her half of the floor. Through analysis, the frequency and channels of surrounding wireless networks have been determined and configuration changes made accordingly. Which of the following would be the NEXT step in setting up this secure wireless network?

  A. Decrease signal strength on the antenna
  B. Change the wireless channel on the WAP
  C. Change the device placement to further obfuscate the signal
  D. Set up encryption on the WAP and clients
  D. Set up encryption on the WAP and clients

  ---

  The encryption will help the clients and server to uniquely identify themselves in an interfering environment.
