質問 # 226 
Refer to the exhibit. An engineer must design an automatic failover solution. The solution should allow HSRP to detect a WAN 1 failure and initiate an automatic failover, making router R2 the active HSRP router. Which two solutions should the engineer choose? (Choose two.)
正解：A、C
質問 # 227
Refer to the exhibit.
Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time. Which solution must the design include?
正解：A
解説：
EIGRP has a function called "EIGRP Ipv6" (But that can still be called "EIGRP")
質問 # 228
An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?
正解：B
解説：
An on-change telemetry subscription is the best solution when the team needs device state data while limiting impact on the device. With periodic telemetry, the device sends subscribed data at a configured interval regardless of whether the value has changed. For state such as shared memory utilization, aggressive periodic polling or streaming can create unnecessary CPU, memory, and bandwidth overhead, especially at scale. On- change telemetry sends an update only when the subscribed data changes, or when a relevant event occurs according to the model and platform behavior. This reduces needless data transmission while still providing timely visibility into meaningful state changes. IPFIX is designed for flow information and traffic accounting rather than detailed device state telemetry. Static telemetry is not the best characterization of the efficient event-driven behavior required here. A periodic subscription can provide the data, but it continuously streams updates and therefore has greater device and collector impact. Cisco model-driven telemetry design favors on- change subscriptions when the operational requirement is state awareness with minimal repeated polling.
質問 # 229
Mobile service provider "A" is going to launch 5G support with the ISP "B" IP network backbone as the underlay transport. Conversational traffic type will be marked with expedited forwarding class, streaming services will be marked with assured forwarding 2 class, and web browsing will be marked with assured forwarding 3 class. Which QoS model meets these requirements if the solution is to be implemented end to end on the ISP_B backbone network?
正解：D
解説：
An 8-class QoS strategy with the DiffServ model supports end-to-end service differentiation across an IP backbone using DSCP markings such as expedited forwarding for conversational traffic and assured forwarding classes for streaming and web traffic. DiffServ is the scalable QoS model typically used across provider backbone networks because traffic is classified and treated by class rather than requiring per-flow reservations.
質問 # 230
An architect must address sustained congestion on the access and distribution uplink of network. QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal network performance. Which two solutions should the architect use to improver network performance? (Choose two)
正解：B、C
解説：
When congestion is sustained and QoS has already been optimized, the correct design response is to add capacity rather than continue tuning packet treatment. QoS manages contention by prioritizing, queuing, shaping, or dropping traffic, but it does not create additional bandwidth. If access-to-distribution uplinks are persistently oversubscribed, business applications will still suffer because the offered load exceeds the available link capacity. Implementing higher-speed uplink interfaces increases the physical bandwidth available for aggregate traffic. Bundling additional uplinks into EtherChannels also increases usable capacity and improves resiliency while presenting a single logical link to the switching and routing design. Random early detection and selective packet discard can improve queue behavior under congestion, but the question states that QoS is already optimized and no longer effective. Reconfiguring QoS to IntServ would add complexity and is not a realistic campus fix. Therefore, the architect should increase uplink capacity through faster links and EtherChannel where the hardware and cabling support it. Reference topics: campus oversubscription, EtherChannel, uplink capacity planning, QoS limitations, congestion remediation.
