NEW QUESTION # 356
Which queuing structure is used on SD-WAN Edge routers?
Answer: C
Explanation:
Cisco SD-WAN edge routers use a queuing model based on LLQ and WFQ concepts. Low Latency Queuing provides strict priority treatment for delay-sensitive traffic such as voice and real-time media, while Weighted Fair Queuing gives proportional service to other traffic classes based on bandwidth allocation. This combination aligns with SD-WAN requirements where business-critical and real-time traffic must be protected without starving normal data applications. FIFO is not appropriate for a multi-class WAN design because it does not distinguish application priority during congestion. A pure priority queue would risk starving lower-priority traffic if it were not controlled by policing or bandwidth limits. Hardware-specific campus queuing models such as 1P-4Q-2T describe certain switch egress queue structures, not the generic SD- WAN edge queuing architecture. In a professional SD-WAN QoS design, traffic is classified, marked, mapped to forwarding classes, and then scheduled using priority and weighted queues according to business intent. Reference topics: Cisco SD-WAN QoS, LLQ, WFQ, forwarding classes, application-aware WAN policy.

NEW QUESTION # 358
A company is planning to open two new branches and allocate the 2a01:c30:16:7009::3800/118 IPv6 network for the region. Each branch should have the capacity to accommodate maximum of 200 hosts. Which two networks should the company use? (Choose two.)
Answer: A,E
Explanation:
The branch subnets must each support up to 200 hosts, so /120 is the correct IPv6 prefix length from the available options. A /120 provides 256 IPv6 addresses, which satisfies the 200-host requirement. A /121 provides only 128 addresses, which is not enough. The parent block is 2a01:0c30:0016:7009::3800/118. A
/118 has 10 host bits, so it contains 1024 addresses and spans from ::3800 through ::3bff. The valid /120 boundaries inside that parent are ::3800/120, ::3900/120, ::3a00/120, and ::3b00/120. From the listed choices,
2a01:0c30:0016:7009::3a00/120 and 2a01:0c30:0016:7009::3b00/120 both fall inside the parent allocation and provide enough address capacity. The /121 options are too small, and ::3c00/120 is outside the /118 parent range. This is a straightforward IPv6 prefix-boundary and capacity calculation. Reference topics: IPv6 subnetting, prefix length, address block boundaries, branch address planning.

An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from sources in another AS. Which feature must the design include?
Answer: D
