質問 # 348
Which PIM mode uses a shared tree only?
正解：C
質問 # 349
An engineer must configure a Cisco router by using the EIGRP stub command to ensure that adjacent neighbors receive all the necessary prefixes. Which EIGRP stub mode must be used to meet this requirement?
正解：B
解説：
The connected stub mode advertises connected routes to adjacent EIGRP neighbors, ensuring that directly attached prefixes from the stub router are shared while still limiting the router's role in the EIGRP topology.
質問 # 350
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?
正解：D
質問 # 351
Which two routing protocols allow for unequal cost load balancing? (Choose two.)
正解：C、E
解説：
EIGRP and BGP are the two listed routing protocols that can support unequal-cost load balancing in Cisco enterprise designs. EIGRP performs unequal-cost load sharing by using the variance command. Feasible successor routes whose feasible distance falls within the variance multiplier can be installed alongside the successor route, provided they satisfy EIGRP loop-prevention rules. This allows traffic to use links with different composite metrics while still maintaining loop-free forwarding. BGP can also support unequal-cost distribution in specific designs, such as using BGP multipath features with additional bandwidth-based mechanisms or policy to influence traffic sharing across nonidentical paths. OSPF and IS-IS commonly support equal-cost multipath, but they do not natively perform EIGRP-style unequal-cost load balancing based on different path metrics. RIPng is also limited by hop-count behavior and is not used for unequal-cost multipath in this context. The correct design answer is therefore EIGRP and BGP. In production, the engineer must still validate hardware forwarding behavior, policy consistency, and whether the traffic-sharing method is per-flow or per-prefix.
質問 # 352
Refer to the exhibit.
C0FD9F48 C9ACDC725EA850EC2476EE1E
A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100 via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for incoming traffic. Which solution should the design include?
正解：D
