問題 #227
A customer with an IPv4 only network topology wants to enable IPv6 connectivity while preserving the IPv4 topology services. The customer plans to migrate IPv4 services to the IPv6 topology, then decommission the IPv4 topology. Which topology supports these requirements?
答案：B
解題說明：
Section: Advanced Addressing and Routing Solutions
問題 #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?
答案：C
解題說明：
There are two types of subscriptions: periodic and on-change. With periodic subscription, data is streamed out to the destination at the configured interval. It continuously sends data for the lifetime of that subscription. With on-change, data is published only when a change in the data occurs such as when an interface or OSPF neighbor goes down.

問題 #229
Refer to the exhibit.
A network engineer must design a multicast solution based on:
* Many-to-many communications between the users and sources
* Support of up to 50 multicast sources
* Users that must register for steams
Which multicast solution must the engineer select?
答案：B
問題 #230 
Refer to the exhibit. These requirements must be met:
* VLANs span multiple access switches.
* All VLANs are trunked on all access switch uplinks to distribution switches.
* The STP version is Rapid PVST+.
Which design provides the fastest spanning-tree convergence?
答案：A
解題說明：
Switch D should be the VLAN 10 primary root, Switch C should be the VLAN 10 secondary root, and link A should remain a Layer 2 trunk. The requirements say VLANs span multiple access switches and all VLANs are trunked on all uplinks. In that design, the distribution interswitch link must remain Layer 2 so the VLAN can exist consistently across the access layer. For fastest and most deterministic Rapid PVST+ convergence, the spanning-tree root bridge should align with the active first-hop gateway for the VLAN. In the exhibit, Switch D is the active gateway for VLAN 10, so making Switch D the primary STP root avoids unnecessary traffic tromboning and keeps the forwarding path optimal. Switch C becomes the secondary root for resiliency. A Layer 3 routed interdistribution link is a best practice when VLANs are not stretched, but it contradicts the stated requirement that VLANs span access switches. Reference topics: Rapid PVST+, STP root placement, FHRP alignment, Layer 2 campus distribution, VLAN spanning design.
問題 #231
