NEW QUESTION # 236
In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?
Answer: A
NEW QUESTION # 237
Refer to the exhibit.
An engineer must optimize the traffic flow of the network. Which change provides a more efficient design between the access and the distribution layer?
Answer: C
NEW QUESTION # 238 
Refer to the exhibit. A network architect is preparing a network design based on EIGRP. Routers are connected using a Cat6a cable type and the inter-router connection speed is limited to 10 Mbps due to distance. During the pilot phase, a DUAL-3-SIA error message is visible. Which action must the engineer take to create a stable design?
Answer: C
Explanation:
The correct action is to configure EIGRP stub behavior on R4. The DUAL-3-SIA message indicates a Stuck- in-Active condition, which occurs when EIGRP sends a query and does not receive a reply within the expected time. Cisco explains that EIGRP stub routing is used to improve stability and reduce resource usage by preventing unnecessary queries from being sent to remote or edge routers. In the described topology, R4 is connected over a limited 10 Mbps inter-router link and should not be treated as a transit router for the rest of the routing domain. Making R4 an EIGRP stub limits the query scope and reduces the chance of active routes waiting on a slow or constrained neighbor. Poison reverse and split-horizon changes address loop prevention and hub-and-spoke update behavior, but they do not directly solve the SIA instability. A summary on R2 may help scaling but does not identify the edge-router query boundary as precisely as EIGRP stub. Reference topics: EIGRP DUAL, Stuck-in-Active, EIGRP stub routing, query scoping, WAN edge stability.
NEW QUESTION # 239 
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?
Answer: B
Explanation:
EIGRP has a function called "EIGRP Ipv6" (But that can still be called "EIGRP")
NEW QUESTION # 240
Which two functions is the Cisco SD-Access Border Node responsible for? (Choose two.)
Answer: B,D
NEW QUESTION # 241
