質問 # 179
An engineer is looking for a standards-driven YANG model to manage a multivendor network environment.
Which model must the engineer choose?
正解：A
解説：
OpenConfig is a vendor-neutral, community-driven initiative focused on developing consistent YANG data models for multivendor network environments. It aims to standardize configurations and operational state across different vendors, reducing fragmentation and ensuring interoperability.
質問 # 180
How do IETF. OpenConfig and Cisco nativo YANG models differ when used to configuro the same feature on an infrastructure device?
正解：D
質問 # 181
Prior to establishing full-mesh iPsec tunnels in a typical Cisco SD-WAN deployment, which mechanism do WAN Edge routers use to exchange Key information for data plane encryption?
正解：D
解説：
Cisco SD-WAN uses the vSmart controller as the control-plane component that distributes the information needed for secure data-plane tunnel establishment. Before WAN Edge devices build full-mesh IPsec tunnels, they must learn reachability and security information through the SD-WAN control plane. Cisco documentation describes the vSmart controller as the centralized control-plane element that exchanges OMP routes, policy, TLOC information, and security parameters with WAN Edge routers. In the traditional SD- WAN key-exchange model, vSmart sends IPsec encryption keys to edge devices so the data plane can be secured without each edge independently negotiating IKEv2 with every other edge. vManage is the management platform and is not the key exchange point. vBond performs orchestration, authentication assistance, and NAT traversal during onboarding, but it is not the data-plane key server. IKEv2 may be used in specific newer or configured security models, but the typical Cisco SD-WAN overlay relies on vSmart for scalable key distribution. Reference topics: Cisco SD-WAN control plane, vSmart, OMP, IPsec key distribution, WAN Edge security.
質問 # 182
A large company is building a new branch office, and the network architect already determined that the branch office will need a /24 network. The architect assigned a network engineer to clean the rest of the addressing plan. The engineer's solution must support:
正解：C
解説：
The correct subnet choice is 192.168.32.0/27. The design must support at least five subnets and at least 25 usable hosts per subnet from a /24 allocation. A /27 leaves five host bits, giving 32 total addresses and 30 usable host addresses after excluding the subnet and broadcast addresses. It also borrows three bits from the
/24 host field, creating eight equal /27 subnets, which satisfies the requirement for at least five departmental networks. A /26 provides 62 usable hosts, but only four subnets inside a /24, so it fails the subnet-count requirement. A /25 provides only two subnets. A /28 provides enough subnets but only 14 usable host addresses, which fails the host requirement. Cisco subnetting guidance uses exactly this host-bit and prefix- length calculation model when selecting VLSM blocks. Reference topics: IPv4 subnetting, CIDR prefix length, host-bit calculation, VLSM design, private IPv4 addressing.
質問 # 183
Which control plane protocol is responsible for ElD-to-RLOC mapping concerning SO-Access Architecture?
正解：D
