 Classification is the QoS feature that uses the IP Precedence bits in the ToS field of the IP packet header to partition traffic into different priority levels. It involves identifying and categorizing packets based on the IP Precedence value, which can range from 0 to 7, with higher values indicating higher priority traffic. This process is essential for applying appropriate QoS policies to different types of traffic, ensuring that high-priority traffic, such as voice and video, receives the necessary bandwidth and low latency treatment. References := Quality of Service (QoS) Configuration Guide, Cisco IOS XE Everest 16.6.x

The configuration shown in the exhibit indicates that NAT (Network Address Translation) is being used to allow a server in one data center (DC2) to communicate with a database in another data center (DC1). The inside global IP is configured for 10.50.250.1, which means this is the IP address that will be used when initiating communication from DC2 to DC1. Since there’s no indication of a similar NAT configuration on the database side, it implies that only the server can initiate communication because it has been assigned an inside global IP address.

 Utilizing data models in a multivendor environment facilitates a unified approach to configuration and management. This is because data models provide a standardized way to represent network configurations, making it easier to manage devices from different vendors within the same network. References: The advantage of using data models is supported by the Implementing and Operating Cisco Service Provider Network Core Technologies source book and corroborated by the search results

In VRRP (Virtual Router Redundancy Protocol), the router with the highest priority is elected as the primary virtual router. Based on the exhibit, Router C has the highest priority value, making it the primary virtual router. References: For more information, you can refer to the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course
