NEW QUESTION # 253
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?
Answer: A
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.

NEW QUESTION # 254
A network administrator installed anew VLANto the network after a company added an additional floor to the office. Users areunable to obtain an IP addresson the new VLAN, but ports on existing VLANs are working properly. Which of the following configurations should the administrator update?
Answer: A
Explanation:
Comprehensive and Detailed Explanation:
When anew VLAN is created, it typically exists on a different subnet. IfDHCP servers are on a different VLAN, the networkneeds an IP helper addressto forward DHCP requests correctly. Without it, clients in the new VLANwon't receive an IP address.
Breakdown of Options:
* A. Scope size- Increasing the DHCP scope would not resolve the issue if requestsaren't reaching the server.
* B. Address reservations- Reservations only assign specific addresses to devices; they do not fix DHCP communication issues.
* C. Lease time- Changing the lease timedoes not impact DHCP functionality across VLANs.
* D. IP helper-Correct answer.This forwardsDHCP requestsacross VLANs to the DHCP server.
NEW QUESTION # 255
A data center interconnect using a VXLAN was recently implemented. A network engineer observes slow performance and fragmentation on the interconnect. Which of the following technologies will resolve the issue?
Answer: A
Explanation:
VXLAN (Virtual Extensible LAN) encapsulates Ethernet frames inside UDP packets, increasing packet size. This can lead to fragmentation and performance degradation unless Jumbo Frames are enabled.

A company is purchasing a 40Gbps broadband connection service from an ISP. Which of the following should most likely be configured on the 10G switch to take advantage of the new service?
Answer: B
