NEW QUESTION # 153
A VoIP phone is plugged in to a port but cannot receive calls. Which of the following needs to be done on the port to address the issue?
- A. Trunk all VLANs on the port.
- B. Tag the traffic to voice VLAN.
- C. Disable VLANs.
- D. Configure the native VLAN.
Answer: B
Explanation:
Understanding VoIP and VLANs:
VoIP (Voice over IP) phones often use VLANs (Virtual Local Area Networks) to separate voice traffic from data traffic for improved performance and security.
Tagging Traffic to Voice VLAN:
Voice VLAN Configuration: The port on the switch needs to be configured to tag traffic for the specific voice VLAN. This ensures that voice packets are prioritized and handled correctly.
VLAN Tagging: VLAN tagging allows the switch to identify and separate voice traffic from other types of traffic on the network, reducing latency and jitter for VoIP communications.
Comparison with Other Options:
Trunk all VLANs on the port: Trunking all VLANs is typically used for links between switches, not for individual device ports.
Configure the native VLAN: The native VLAN is for untagged traffic and does not address the need for separating and prioritizing voice traffic.
Disable VLANs: Disabling VLANs would mix voice and data traffic, leading to potential performance issues and lack of traffic separation.
Implementation:
Configure the switch port connected to the VoIP phone to tag the traffic for the designated voice VLAN, ensuring proper network segmentation and quality of service.

NEW QUESTION # 154
A network engineer is completing a wireless installation in a new building. A requirement is that all clients be able to automatically connect to the fastest supported network. Which of the following best supports this requirement?
- A. Enabling band steering
- B. Adding a captive portal
- C. Configuring MAC filtering
- D. Disabling the 5GHz SSID
Answer: A
Explanation:
Band steering automatically directs capable wireless devices to connect to the faster 5GHz band instead of the slower 2.4GHz band. This ensures that clients use the most efficient connection available.
*Why not the other options?
*Disabling the 5GHz SSID (B): Would force all clients onto slower 2.4GHz networks, reducing speed and performance.
*Captive portal (C): Used for guest authentication but does not impact connection speed selection.
*MAC filtering (D): Used for access control, but it does not ensure clients connect to the fastest available network.
NEW QUESTION # 155
What type of attack allows an attacker to send traffic into another VLAN without authorization?
- A. ARP spoofing
- B. VLAN hopping
- C. DNS poisoning
- D. MAC flooding
Answer: B
Explanation:
VLAN hopping allows an attacker to send traffic into another VLAN without authorization, often by impersonating a switch and negotiating a trunk link. This lets the attacker traverse into normally inaccessible VLANs.
* A. MAC flooding disrupts switch operations but does not cross VLANs.
* B. DNS poisoning corrupts name resolution.
* D. ARP spoofing reroutes local traffic but doesn't grant VLAN traversal.

NEW QUESTION # 156
A customer is adding fiber connectivity between adjacent buildings. A technician terminates the multimode cable to the fiber patch panel. After the technician connects the fiber patch cable, the indicator light does not turn on. Which of the following should a technician try first to troubleshoot this issue?
- A. Verify the fiber size.
- B. Reterminate the fibers.
- C. Reverse the fibers.
- D. Examine the cable runs for visual faults.
Answer: C
Explanation:
When working with fiber optic cables, one common issue is that the transmit (TX) and receive (RX) fibers might be reversed. The first step in troubleshooting should be to reverse the fibers at one end to ensure they are correctly aligned (TX to RX and RX to TX). This is a simple and quick step to rule out a common issue before moving on to more complex troubleshooting.

* Enter the command tracert <IP address> to trace the route and measure the latency of packets from the device to another device on the network by sending and receiving packets withincreasing TTL values.
Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.
Here is an example of how to enter commands in PC1:
* Click on PC1 to open its terminal window.
* Enter the command ipconfig /all to display the IP configuration of PC1. You should see that PC1 has an incorrect IP address of 192.168.2.10, which belongs to VLAN 2 instead of VLAN 1.
* Enter the command ping 192.168.1.1 to test the connectivity to Core Switch 1. You should see that PC1 is unable to ping Core Switch 1 because they are on different subnets.
* Enter the command tracert 192.168.1.1 to trace the route to Core Switch 1. You should see that PC1 is unable to reach Core Switch 1 because there is no route between them.
You can use the same steps to enter commands in other devices, such as PC3, PC4, PC5, and Server 1.

NEW QUESTION # 160
A network administrator suspects users are being sent to malware sites that are posing as legitimate sites. The network administrator investigates and discovers that user workstations are configured with incorrect DNS IP addresses. Which of the following should the network administrator implement to prevent this from happening again?
- A. Dynamic ARP inspection
- B. Port security
- C. DHCP snooping
- D. Access control lists
Answer: C
Explanation:
DHCP snooping is a security feature on network switches that helps to prevent unauthorized (rogue) DHCP servers from assigning IP addresses to clients. By implementing DHCP snooping, the network administrator can restrict DHCP responses to authorized servers only, preventing unauthorized DHCP configurations, such as incorrect DNS IPs, from being assigned to clients.
This helps prevent man-in-the-middle attacks where malicious actors misconfigure DNS to redirect users to fraudulent sites.

Network Health:
WAN 2 appears to have a lower average latency and loss percentage, which would make it the preferred WAN station for VoIP traffic. VoIP traffic requires low latency and packet loss to ensure good voice quality and reliability. WAN 1 seems to have higher RAM and processor usage, which could also affect the performance of VoIP traffic.
Here's the summary of the key metrics for WAN 1 and WAN 2 from the image provided:
* WAN 1:
* Uplink Speed: 10G
* Total Usage: 26.969GB Up / 1.748GB Down
* Average Throughput: 353MBps Up / 23.42MBps Down
* Loss: 2.51%
* Average Latency: 24ms
* Jitter: 9.5ms
* WAN 2:
* Uplink Speed: 1G
* Total Usage: 930GB Up / 138GB Down
* Average Throughput: 12.21MBps Up / 1.82MBps Down
* Loss: 0.01%
* Average Latency: 11ms
* Jitter: 3.9ms
For VoIP traffic, low latency and jitter are particularly important to ensure voice quality. While WAN 1 has higher bandwidth and throughput, it also has higher latency and jitter compared to WAN 2. However, WAN 2 has much lower loss, lower latency, and lower jitter, which are more favorable for VoIP traffic that is sensitive to delays and variation in packet arrival times.
Given this information, WAN 2 would generally be preferred for VoIP traffic due to its lower latency, lower jitter, and significantly lower loss percentage, despite its lower bandwidth compared to WAN 1. The high bandwidth of WAN 1 may be more suitable for other types of traffic that are less sensitive to latency and jitter, such as bulk data transfers.
Device Monitoring:
the device that is experiencing connectivity issues is the APP Server or Router 1, which has a status of Down.
This means that the server is not responding to network requests or sending any data. You may want to check the physical connection, power supply, and configuration of the APP Server to troubleshoot the problem.
NEW QUESTION # 164
A small business is deploying new phones, and some of the phones have full HD videoconferencing features. The Chief Information Officer (CIO) is concerned that the network might not be able to handle the traffic if it reaches a certain threshold. Which of the following can the network engineer configure to help ease these concerns?
- A. A VLAN with 100Mbps speed limits
- B. A smaller subnet mask
- C. Full duplex on all user ports
- D. An IP helper to direct VoIP traffic
Answer: C
Explanation:
Full duplex mode allows devices to send and receive data simultaneously, improving network performance and reducing congestion, which is critical for VoIP and video conferencing.
Breakdown of Options:
A . A VLAN with 100Mbps speed limits - VLANs segment traffic but limiting speeds to 100Mbps would worsen video performance.
B . An IP helper to direct VoIP traffic - IP helper is used for DHCP relay, not for VoIP optimization.
C . A smaller subnet mask - A smaller subnet reduces IP address availability but does not improve network performance.
D . Full duplex on all user ports - Correct answer. Full duplex eliminates collisions, allowing better VoIP and video performance.

You are setting up a new Access Point (AP) on a network where previous APs have been functioning correctly.
However, the new AP fails to power on. What is the most likely cause of the issue?
- A. CRC
- B. Duplex mismatch
- C. Signal strength
- D. Power budget
Answer: D
Explanation:
When deploying multiple Power over Ethernet (PoE) devices, the switch's power budget can be exhausted. If the available wattage on the switch cannot supply the additional AP, it will fail to power on. This is the most likely cause when previous APs worked fine but a new one does not.
* A. Signal strength affects wireless connectivity, not whether the AP powers up.
* B. Duplex mismatch causes poor throughput, not power failure.
* D. CRC errors point to cabling issues but do not prevent booting if no power is available.
