  A. EIGRP
  B. OSPF
  C. RIP
  D. BGP
  B. OSPF

  ---

  Explanation/Reference:

  OSPF uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks

• Question 583:

  A network technician is troubleshooting a problem with a user's client-to-site VPN connection. The user is unable to establish a connection to the server, but the error message that appears on screen does not contain useful information. Which of the following should the technician do NEXT to troubleshoot the issue?

  A. Reconfigure the user's VPN connection in the router to fix profile corruption.
  B. Inform the user that provisioning sometimes fails and the connection needs to be attempted again.
  C. Review the logs in the VPN client to check for any informational messages.
  D. Verify the system has the latest OS patches installed.
  C. Review the logs in the VPN client to check for any informational messages.

• Question 584:

  A user reports that a crucial fileshare is unreachable following a network upgrade that was completed the night before. A network technician confirms the problem exists. Which of the following troubleshooting steps should the network technician perform NEXT?

  A. Establish a theory of probable cause.
  B. Implement a solution to fix the problem.
  C. Create a plan of action to resolve the problem.
  D. Document the problem and the solution.
  A. Establish a theory of probable cause.

  ---

  Explanation/Reference:

  Establishing a theory of probable cause is the third step in the general troubleshooting process, after identifying the problem and gathering information. Establishing a theory of probable cause involves using the information gathered to formulate one or more possible explanations for the problem and testing them to verify or eliminate them. In this scenario, the network technician has confirmed the problem exists and should proceed to establish a theory of probable cause based on the information available, such as the network upgrade that was completed the night before. Implementing a solution to fix the problem is the fifth step in the general troubleshooting process, after establishing a plan of action. Implementing a solution involves applying the chosen method or technique to resolve the problem and verifying its effectiveness. In this scenario, the network technician has not established a plan of action yet and should not implement a solution without knowing the cause of the problem. Creating a plan of action to resolve the problem is the fourth step in the general troubleshooting process, after establishing a theory of probable cause. Creating a plan of action involves selecting the best method or technique to address the problem based on the available resources, constraints, and risks. In this scenario, the network technician has not established a theory of probable cause yet and should not create a plan of action without knowing the cause of the problem. Documenting the problem and the solution is the seventh and final step in the general troubleshooting process, after implementing preventive measures. Documenting the problem and the solution involves recording the details of the problem, its symptoms, its cause, its solution, and its preventive measures for future reference and improvement. In this scenario, the network technician has not implemented preventive measures yet and should not document the problem and the solution without resolving and preventing it.

• Question 585:

  Logs show an unauthorized IP address entering a secure part of the network every night at 8:00 pm. The network administrator is concerned that this IP address will cause an issue to a critical server and would like to deny the IP address at the edge of the network. Which of the following solutions would address these concerns?

  A. Changing the VLAN of the web server
  B. Changing the server's IP address
  C. Implementing an ACL
  D. Instating a rule on the firewall connected to the web server
  C. Implementing an ACL

• Question 586:

  A technician recently set up a small office network for nine users. When the installation was complete, all the computers on the network showed addresses ranging from 169.254.0.0 to 169.254.255.255. Which of the following types of address ranges does this represent?

  A. Private
  B. Public
  C. APIPA
  D. Classless
  C. APIPA

  ---

  Explanation/Reference:

  APIPA stands for Automatic Private IP Addressing (APIPA). It is a feature or characteristic in operating systems (eg. Windows) which enables computers to self-configure an IP address and subnet mask automatically when their DHCP (Dynamic Host Configuration Protocol) server isn't reachable.

• Question 587:

  A user is experimenting with audio transmissions and would like the transmissions to reach several specific devices simultaneously over the IP network. The user requests assistance from a network technician to configure the appropriate features within the SOHO. Which of the following should the technician configure to meet the requirements?

  A. Unicast
  B. Multicast
  C. Anycast
  D. Broadcast
  B. Multicast

• Question 588:

  A network requirement calls for segmenting departments into different networks. The campus network is set up with users of each department in multiple buildings. Which of the following should be configured to keep the design simple and efficient?

  A. MDIX
  B. Jumbo frames
  C. Port tagging
  D. Flow control
  C. Port tagging

  ---

  Explanation/Reference:

  Port tagging is a technique that involves adding a tag or identifier to the frames or packets that belong to a certain VLAN. A VLAN is a logical segment of a network that isolates traffic between different groups of devices. Port tagging allows devices on different physical ports or switches to communicate with each other as if they were on the same port or switch. Port tagging can help keep the design simple and efficient by reducing the number of physical ports and switches needed to segment departments into different networks.

• Question 589:

  A company wants to implement a large number of WAPs throughout its building and allow users to be able to move around the building without dropping their connections.

  Which of the following pieces of equipment would be able to handle this requirement?

  A. A VPN concentrator
  B. A load balancer
  C. A wireless controller
  D. A RADIUS server
  C. A wireless controller

  ---

  Explanation/Reference:

  A wireless controller would be able to handle the requirement of implementing a large number of WAPs throughout the building and allowing users to move around without dropping their connections. A wireless controller is a device that centrally manages and configures multiple wireless access points (WAPs) on a network. It can provide features such as load balancing, roaming, security, QoS, and monitoring for the wireless network. A wireless controller can also support wireless mesh networks, where some WAPs act as relays for other WAPs to extend the wireless coverage.
