  A. Transport
  B. Application
  C. Internet
  D. Network Interface
  B. Application

• Question 172:

  A company has recently allowed its employees to telecommute two days a week. The employees MUST have a minimum of 1Mbps non-shared connection to the Internet. Which of the following MUST the employees have at their home in order to connect to the Internet?

  A. ISDN

  Digital subscriber line (DSL, originally digital subscriber loop) is a family of technologies that provide Internet access by transmitting digital data over the wires of a local telephone network.

• Question 173:

  Which of the following copper cable types should be chosen to run gigabit speeds through a dropped ceiling that returns airflow?

  A. Non-Plenum CAT5
  B. Non-Plenum CAT5e
  C. Plenum CAT5
  D. Plenum CAT5e
  D. Plenum CAT5e

  ---

  Cat 5e 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, 100BASETX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet).

• Question 174:

  Stateful packet inspection is a security technology used by which of the following devices?

  A. Unmanaged switch
  B. Hardware firewall
  C. Bridge
  D. IDS
  B. Hardware firewall

  ---

  Explanation Explanation/Reference:With Stateful Packet Inspection (SPI), every time a packet is sent out of the computer, the firewall keeps track of it. When a packet comes back to the firewall, the firewall can tell whether or not the in-bound packet is a reply to the packet that was sent out.This way, the firewall can handle most network traffic safely without a complex configuration of firewall rules.

• Question 175:

  A network technician is configuring a firewall access list to secure incoming connections to an email server. The internal address of this email server is 192.168.1.143. The firewall should allow external email servers to send email to the email server. The email server also supports client access via a web browser. Only secure protocols should be used, and only the necessary ports should be open. Which of the following ACL rules should be configured in the firewall's WAN port? (Select TWO).

  A. Permit 192. 168.1.143 25
  B. Permit 192. 168.1.143 80
  C. Permit 192. 168.1.143 110
  D. Permit 192. 168.1.143 143
  E. Permit 192. 168.1.143 443
  F. Permit 192. 168.1.143 587
  A. Permit 192. 168.1.143 25
  C. Permit 192. 168.1.143 110

• Question 176:

  A company has been just opened a new site in another country. Both sites share information across the WAN continuously throughout the business day. Which of the following should be implemented to ensure both sites are accessible?

  A. Traffic shaping
  B. QoS
  C. Caching engines
  D. High availability
  D. High availability

• Question 177:

  Several users from the finance department report that they are able to access the Internet, but unable to connect to their financial applications. The network technician is unable to ping the finance server. The technician decides to check the switch and determines that Internet access is working. Which of the following is a possible cause of the access issues?

  A. Faulty cable
  B. Remote management disabled
  C. Improper VLAN assignment
  D. Mismatched duplex
  C. Improper VLAN assignment

  ---

  Explanation Explanation/Reference:Finance Server is placed in same VLAN which is assigned to finance users if they are able to access internet that's means connectivity to switch is good, so we have to check the VLAN assigned to users.

• Question 178:

  Which of the following is used to define how much bandwidth can be used by various protocols on the network?

  A. Traffic shaping
  B. High availability
  C. Load balancing
  D. Fault tolerance
  A. Traffic shaping

  ---

  If a network connection becomes saturated to the point where there is a significant level of contention, network latency can rise substantially. Traffic shaping is used to control the bandwidth used by network traffic. In a corporate environment, business-related traffic may be given priority over other traffic. Traffic can be prioritized based on the ports used by the application sending the traffic. Delayed traffic is stored in a buffer until the higher priority traffic has been sent.

• Question 179:

  Compare the settings below to determine which of the following issues is preventing the user from connecting to a wireless network.

  

  Which of the following settings is incorrect on the client?

  A. The mode is incorrect
  B. SSID Mismatch
  C. Incorrect WEP Key
  D. Channel is set incorrectly
  B. SSID Mismatch

  ---

  Explanation Explanation/Reference:the first thing which will be checked is the SSID and it is case sensitive but in the above shown example, it is not same so it will stop user from connecting.

• Question 180:

  Users are reporting their network is extremely slow. The technician discovers pings to external hosts have excessive response times. However, internal pings to printers and other PC have acceptable response times. Which of the following steps should the technician take NEXT?

  A. Determine if any network equipment was replaced recently.
  B. Verify malware has not disabled the users' PC firewalls.
  C. Replace users' network cables with known-good network cables.
  D. Power cycle the web server.
  A. Determine if any network equipment was replaced recently.
