An organization is designing a detailed QoS plan that limits bandwidth to specific rates. Which two parameters are supported by the traffic policing feature? (Choose two.)
Answer: AE
When working with policing there are three categories that we can use to see if a packet conforms the traffic contract or not: Conforming Exceeding Violating

An engineer must propose a QoS architecture model that allows an application to inform the network of its traffic profile and to request a particular type of service to support its bandwidth and delay requirements. The application requires consistent and dedicated bandwidth end to end. Which QoS architecture model meets these requirements?
Answer: D
An engineer is designing a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?
Answer: D
Bidir-PIM is designed to be used for many-to-many applications within individual PIM domains. Multicast groups in bidirectional PIM mode can scale to an arbitrary number of sources without incurring overhead due to the number of sources. So answer is D -> BIDIR PIM

An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point. Which multicast protocol meets these requirements?
Answer: B
In addition - please, note, the RP is required for BIDIR PIM - refer to: In bidirectional mode, traffic is routed only along a bidirectional shared tree that is rooted at the rendezvous point (RP) for the group https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/16-12/configuration_guide/ip_mcast_rtng/b_1612_ip_mcast_rtng_9600_cg/configuring_pim.html#id_111801

What are two valid scaling techniques when an EIGRP network is designed that consists of more than 1000 routers? (Choose two.)
Answer: AE
What is the function of the multicast Reverse Path Forwarding check?
Answer: A
An architect is designing a multicast solution for a network that contains over 100 routers. The architect plans to create several multicast domains and balance the PIM-SM traffic within the network. Which technology should the architect include in the design?
Answer: D
An engineer must design a scalable QoS architecture that allows the separation of the traffic into classes based on predefined business requirements. The design must also utilize the differentiated services code points as the QoS priority descriptor value and support at least 10 levels of classification. Which QoS technology should the engineer include in the design?
Answer: B
A network engineer is redesigning a company's QoS solution. The company is currently using IP Precedence, but the engineer plans to move to DiffServ. It is important that the new solution provide backward compatibility with the current solution. Which technology should the design include?
Answer: C
FiffServ is backward compatible with IP Precedence (Ip-Precedence uses the 3 most signifcant bits of the ToS byte, whereas Diffserve uses the fost significant six bits - which includ the ones from IP precedence)

An enterprise customer has these requirements: ✑ end-to-end QoS for the business-critical applications and VoIP services based on CoS marking. ✑ flexibility to offer services such as IPv6 and multicast without any reliance on the service provider. ✑ support for full-mesh connectivity at Layer 2. Which WAN connectivity solution meets these requirements?
Answer: D
