NEW QUESTION # 158
A systems administrator is running a VoIP network and is experiencing jitter and high latency. Which of the following would BEST help the administrator determine the cause of these issues?
- A. Implementing LDAP on the network
- B. Enabling RADIUS on the network
- C. Configuring SNMP traps on the network
- D. Establishing NTP on the network
Answer: C
Explanation:
SNMP (Simple Network Management Protocol) is a protocol that allows network devices to communicate with a network management system (NMS) for monitoring and configuration purposes. SNMP traps are unsolicited messages sent by network devices to the NMS when certain events or conditions occur, such as errors, failures, or thresholds. Configuring SNMP traps on the network would best help the administrator determine the cause of jitter and high latency on a VoIP network, as they would provide real-time alerts and information about the network performance and status. Enabling RADIUS on the network is not relevant to troubleshooting VoIP issues, as RADIUS is a protocol that provides authentication, authorization, and accounting services for network access. Implementing LDAP on the network is also not relevant to troubleshooting VoIP issues, as LDAP is a protocol that provides directory services for storing and querying information about users, groups, devices, etc. Establishing NTP on the network is not directly related to troubleshooting VoIP issues, as NTP is a protocol that synchronizes the clocks of network devices.
NEW QUESTION # 159
A network administrator discovers that users in an adjacent building are connecting to the company's guest wireless network to download inappropriate material. Which of the following can the administrator do to MOST easily mitigate this issue?
- A. Adjust the wireless channels
- B. Reduce the wireless power levels
- C. Enable wireless client isolation
- D. Enable wireless port security
Answer: B
Explanation:
Explanation
Reducing the wireless power levels can limit the range of the guest wireless network and prevent users in an adjacent building from connecting to it. Adjusting the wireless channels or enabling wireless client isolation will not affect the signal strength or coverage of the guest network. Enabling wireless port security will not work on a guest network that does not use authentication or MAC address filtering.

NEW QUESTION # 161
Users have reported an issue connecting to a server over the network. A workstation was recently added to the network and configured with a shared USB printer. Which of the following is most likely causing the issue?
- A. The web server's back end was designed for only single-threaded applications.
- B. The switch is oversubscribed and cannot handle the additional throughput.
- C. The printer is tying up the server with DHCP discover messages
- D. The workstation was configured with a static IP that is the same as the server.
Answer: D
Explanation:
The workstation was configured with a static IP that is the same as the server is the most likely cause of the issue where users are unable to access any network resources. A static IP address is an IP address that is manually assigned to a device and does not change over time. A static IP address can be useful for devices that need to be easily identified or accessed on a network, such as servers or printers. However, if two devices on the same network have the same static IP address, it can cause an IP address conflict. An IP address conflict occurs when two devices try to use the same IP address at the same time, resulting in network communication errors or failures. An IP address conflict can prevent users from accessing any network resources that rely on the IP address for identification or routing.

NEW QUESTION # 162
A technician monitors a switch interface and notices it is not forwarding frames on a trunked port. However, the cable and interfaces are in working order. Which of the following is MOST likely the cause of the issue?
- A. Flow control
- B. STP policy
- C. 802.1Q configuration
- D. Frame size
Answer: C
Explanation:
802.1Q configuration is the most likely cause of the issue where a switch interface is not forwarding frames on a trunked port. 802.1Q is a standard that defines how to create and manage virtual LANs (VLANs) on a switched network. VLANs are logical segments of a network that group devices based on criteria such as function, department, or security level. VLANs can improve network performance, security, and manageability by reducing broadcast domains, isolating traffic, and enforcing policies. A trunked port is a switch port that can carry traffic from multiple VLANs over a single physical link by adding a VLAN tag to each frame. A VLAN tag is a 4-byte header that identifies the VLAN ID and priority of each frame. A trunked port requires 802.1Q configuration to specify which VLANs are allowed or disallowed on the port, and which VLAN is the native or untagged VLAN. If the 802.1Q configuration is incorrect or mismatched between switches, frames may be dropped or misrouted on the trunked port.

NEW QUESTION # 163
A wireless network was installed in a warehouse for employees to scan crates with a wireless handheld scanner. The wireless network was placed in the corner of the building near the ceiling for maximum coverage However users in the offices adjacent lo the warehouse have noticed a large amount of signal overlap from the new network Additionally warehouse employees report difficulty connecting to the wireless network from the other side of the building; however they have no issues when Ihey are near the antenna Which of the following is MOST likely the cause?
- A. The wireless signal is being refracted by the warehouse's windows
- B. An omnidirectional antenna was used instead of a unidirectional antenna
- C. The wireless access points are using channels from the 5GHz spectrum
- D. The antenna's power level was set too high and is overlapping
Answer: B
Explanation:
Explanation
An omnidirectional antenna was used instead of a unidirectional antenna, which is most likely the cause of the wireless network issues. An omnidirectional antenna provides wireless coverage in all directions from the antenna, which can cause signal overlap with adjacent offices and interference with other wireless networks. A unidirectional antenna, on the other hand, provides wireless coverage in a specific direction from the antenna, which can reduce signal overlap and interference and increase signal range and quality. A unidirectional antenna would be more suitable for a warehouse environment where users are located on one side of the building1. References:

NEW QUESTION # 164
A network engineer is configuring new switches. Some of the trunk ports are in a blocking state. Which of the following should the network engineer reconfigure?
- A. Flow control
- B. Port mirroring
- C. STP
- D. LACP
Answer: C
Explanation:
STP (Spanning Tree Protocol) is a protocol that prevents loops in a network by placing some of the switch ports in different states, such as blocking, listening, learning, forwarding, or disabled. A port in the blocking state does not forward frames or participate in frame forwarding. A network engineer can reconfigure STP to change the port states and avoid blocking ports that are needed for trunking.

NEW QUESTION # 169
A network administrator is setting up several loT devices on a new VLAN and wants to accomplish the following
1. Reduce manual configuration on each system
2. Assign a specific IP address to each system
3. Allow devices to move to different switchports on the same VLAN
Which of the following should the network administrator do to accomplish these requirements?
- A. Set up a reservation for each device
- B. Use DHCP exclusions to address each device
- C. Implement private VLANs for each device
- D. Configure a static IP on each device
Answer: A
Explanation:
A reservation is a feature of DHCP that assigns a specific IP address to a device based on its MAC address. This way, the device will always receive the same IP address from the DHCP server, regardless of its location or connection time. A network administrator can set up a reservation for each loT device to accomplish the requirements of reducing manual configuration, assigning a specific IP address, and allowing devices to move to different switchports on the same VLAN.

NEW QUESTION # 170
A technician is troubleshooting a user's connectivity issues and finds that the computer's IP address was changed to 169.254.0.1.
Which of the following is the most likely reason?
- A. The computer was set up to perform as an NTP server.
- B. The computer is on a VPN and is the first to obtain a different IP address in that network.
- C. Two or more computers have the same IP address in the ARP table.
- D. The computer automatically set this address because the DHCP was not available.
Answer: D
Explanation:
IP addresses beginning with 169.254. are called link-local addresses or APIPA (Automatic Private IP Addressing)1. They are assigned by the computer itself when it cannot reach a DHCP server to obtain a valid IP address from the network2. This can happen for several reasons, such as a faulty router, a misconfigured network, or a disconnected cable3.
To troubleshoot this issue, the technician should check the network settings, the router configuration, and the physical connection of the computer. The technician should also try to renew the IP address by using the command ipconfig /renew in Windows or dhclient in Linux. If the problem persists, the technician may need to contact the network administrator or the ISP for further assistance.
