NEW QUESTION # 191
A network engineer must design a multicast solution to prevent the spoofing of multicast streams and ensure efficient bandwidth utilization. The network will be merged with another multicast domain in the future, and the merge must require minimum effort. Which two solutions meet the customer requirements? (Choose two.)
- A. IGMPv3
- B. IGMPv2
- C. PIM-SSM

NEW QUESTION # 192
A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?
- A. Identify the applications and reserve the required bandwidth on the perimeter routers.
- B. Identify the applications with NBAR2 and allocate the required bandwidth accordingly.
- C. Identify the port used by each application and apply a minimum bandwidth guarantee.
- D. Identify the application ports, create groupings, and rate-limit the required bandwidth.
Answer: B
Explanation:
using NBAR to identify application and bandwidth usage, then adjust existing QoS polices would be a more simple option. Of course, B is still ok if the network admin know all traffic and bandwidth consumption by other tools, say netflow. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_nbar/configuration/15-mt/qos-nbar-15-mt-book/nbar-protocl-discvry.html#GUID-ED1AEDA1-AE69-45C3-A77E-2AF881CA9C36
