• Question 231:

  Which of the following routing protocols uses bandwidth and delay as the primary metrics to calculate the best path?

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

• Question 232:

  A technician is connecting DSL for a new customer. After installing and connecting the on-premises equipment, the technician verifies DSL synchronization. When connecting to a workstation, however, the link LEDs on the workstation and modem do not light up. Which of the following should the technician perform during troubleshooting?

  A. Identify the switching loops between the modem and the workstation.
  B. Check for asymmetrical routing on the modem.
  C. Look for a rogue DHCP server on the network.
  D. Replace the cable connecting the modem and the workstation.
  D. Replace the cable connecting the modem and the workstation.

  ---

  Explanation/Reference:

  If the link LEDs on the workstation and modem do not light up when connecting to a workstation, it could indicate a problem with the cable connecting them. The cable could be damaged, defective, or incompatible with the devices. A technician should replace the cable with a known good one and check if the link LEDs light up. If not, the problem could be with the network interface cards (NICs) on the workstation or modem. References: https://www.comptia.org/blog/whatis-link-light

• Question 233:

  SIMULATION

  You have been tasked with setting up a wireless network in an office. The network will consist of 3 Access Points and a single switch. The network must meet the following parameters:

  1. The SSIDs need to be configured as CorpNet with a key of S3cr3t!

  2. The wireless signals should not interfere with each other

  3. The subnet the Access Points and switch are on should only support 30 devices maximum

  4. The Access Points should be configured to only support TKIP clients at a maximum speed

  INSTRUCTONS

  Click on the wireless devices and review their information and adjust the settings of the access points to meet the given requirements.

  If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

• Question 234:

  A technician is troubleshooting network connectivity from a wall jack. Readings from a multimeter indicate extremely low ohmic values instead of the rated impedance from the switchport. Which of the following is the MOST likely cause of this issue?

  A. Incorrect transceivers
  B. Faulty LED
  C. Short circuit
  D. Upgraded OS version on switch
  C. Short circuit

  ---

  Explanation/Reference:

  Short circuit: A short circuit occurs when there is an unintended connection between two conductors or components that are not supposed to be electrically connected. This can result in extremely low resistance (ohmic value), causing a significant current flow. In the context of network cabling, a short circuit could occur due to damaged or frayed cables, improper termination, or physical damage to the cabling infrastructure.

• Question 235:

  A user has called the help desk with a problem reaching certain servers within the organization. The organization is using RFC 1819 for internal networks. The servers having trouble are configured with the following IP addresses: 192. 130.

  135. 5 and 192. 130. 135. 6.

  The user cannot connect to the correct servers. Which of the following explain why this is happening to the user?

  A. The network has been configured with an inappropriate scheme
  B. The serves are periodical/ going offline and rejecting the connection.
  C. The default route in the user's computer points to the wrong upstream device.
  D. The IPS system is flagging the traffic as suspicious and terminating the connection.
  A. The network has been configured with an inappropriate scheme

• Question 236:

  Which of the following is MOST appropriate for enforcing bandwidth limits when the performance of an application is not affected by the use of buffering but is heavily impacted by packet drops?

  A. Traffic shaping
  B. Traffic policing
  C. Traffic marking
  D. Traffic classification
  A. Traffic shaping

  ---

  Explanation/Reference:

  "Instead of making a minimum amount of bandwidth available for specific traffic types, you might want to limit available bandwidth. Both traffic policing and traffic shaping tools can accomplish this objective. Collectively, these tools are called

  traffic conditioners.

  Policing can be used in either the inbound or the outbound direction, and it typically discards packets that exceed the configured rate limit, which you can think of as a speed limit for specific traffic types. Because policing drops packets,

  resulting in re-transmissions, it is recommended for higher-speed interfaces. Shaping buffers (and therefore delays) traffic exceeding a configured rate. Therefore, shaping is recommended for slower-speed interfaces."

• Question 237:

  Which of the following does OSPF use to communicate routing updates?

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

  ---

  Explanation/Reference:

  OSPF uses multicast addresses to communicate routing updates. It sends its updates using the multicast address 224.0.0.5, which is used for all OSPF routers, and the multicast address 224.0.0.6, used for all OSPF designated routers. This method is efficient in terms of network bandwidth, as it allows OSPF routers to receive updates without the need for sending individual updates to each router (unicast) or broadcasting to all devices in the network (broadcast).

• Question 238:

  A network administrator needs to run a single command-line tool capable of displaying routing table and multicast memberships. Which of the following would BEST help the administrator achieve the requirements?

  A. arp
  B. show route
  C. show config
  D. netstate
  A. arp

• Question 239:

  A PC and a network connectivity, and a help desk technician is attempting to resolve the issue. The technician plans to run a constant ping command from a Windows workstation while testing various possible reasons for the connectivity issue. Which of the following should the technician use?

  A. ping -w
  B. ping -i
  C. ping -s
  D. ping -t
  D. ping -t

  ---

  Explanation/Reference:

  The ping -t command is used in the Windows command prompt (CMD) to continuously ping a target IP address or domain name until the command is manually stopped by the user. The -t option essentially creates an ongoing loop of ping requests, providing a real-time display of round-trip times and potential packet loss. This can be useful for monitoring network stability and diagnosing intermittent connectivity issues over an extended period.

• Question 240:

  A technician received a report that some users in a large, 30-floor building are having intermittent connectivity issues. Users on each floor have stable connectivity, but do not have connectivity to other floors. Which of the following devices is MOST likely causing the issue?

  A. User devices
  B. Edge devices
  C. Access switch
  D. Core switch
  D. Core switch
