질문 # 195
An engineer is working with NETCONF and Cisco NX-OS based devices.
The engineer needs a YANG model that supports a specific feature relevant only to Cisco NX- OS.
Which model must the engineer choose?
정답：C
설명：
NXOS has a comprehensive number of both native and open YANG models, that allow you to manage the rich feature-set that NXOS provides. Data models provide a structured and well- defined base that facilitates programmatic interaction with NXOS devices. The list of supported models includes native, OpenConfig and IETF models. In addition, YANG provides a modeling language optimized for network devices and with a growing number of tools and utilities.
OpenConfig and IETF are vendor agnostic models, that abstract the detailed configuration across OSs and platforms.
질문 # 196
Which two best practices must be followed when designing an out-of-band management network? (Choose two.)
정답：A,D
설명：
An out-of-band management network should be isolated from the production data network and protected with strict access control. Cisco SAFE design principles treat the management plane as a sensitive function because it provides administrative access to infrastructure devices. Isolation ensures that production outages, routing problems, or compromised user segments do not automatically remove the operator's ability to manage routers, switches, firewalls, and controllers. Access control ensures that only authorized administrators and management systems can reach the management interfaces and protocols. The management network should not be treated as a backup data path, because that undermines separation and can expose management devices to production traffic risks. It should also not be used as a general-purpose data backup network. "Facilitate network integration" is too vague and can conflict with the isolation requirement. Therefore, the best practices are to enforce access control and ensure network isolation. In a mature design, this normally includes dedicated management interfaces or VRFs, jump hosts, AAA, logging, and tightly controlled management protocol access.

질문 # 198
Refer to the exhibit.
A customer is running HSRP on the core routers. Over time the company has grown and requires more network capacity. In the current environment, some of the downstream interfaces are almost fully utilized, but others are not. Which solution improves the situation?
정답：D
질문 # 199
Which two routing protocols allow for unequal cost load balancing? (Choose two.)
정답：B,C
설명：
Unequal cost load balancing is a feature that allows traffic to be distributed across unequal-cost paths to the same destination, which can increase network utilization and improve overall performance.
EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are two routing protocols that support unequal cost load balancing.
In EIGRP, unequal cost load balancing can be achieved by adjusting the "variance" parameter, which is a multiplier that determines the maximum metric of a feasible successor. The feasible successor is a backup route that meets the feasibility condition, which means its reported distance (the sum of the metric from the successor router and the advertised distance to the destination) is less than the current best path's metric. By default, EIGRP only considers successors with the same metric as the best path, but by increasing the variance, EIGRP can include feasible successors with higher metrics.
In OSPF, unequal cost load balancing can be achieved by enabling the "variance" command, which allows OSPF to use paths with metrics that are up to a certain multiple of the best path's metric. For example, if the variance is set to 2, OSPF can use paths with a metric that is up to twice the metric of the best path.
IS-IS (Intermediate System to Intermediate System) and BGP (Border Gateway Protocol) do not support unequal cost load balancing.
RIPng (Routing Information Protocol next generation) is a distance-vector routing protocol that does not support unequal cost load balancing.
