質問 # 163
A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:

* reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)
- A. Configure broadcast and multicast storm control on all switches.
- B. Configure dynamic trunking protocol to propagate VLAN information.
- C. Use VTP to propagate VLAN information and to prune unused VLANs.
- D. Implement Rapid PVST+ instead of STP.
- E. Implement MST instead of STP.
正解：A、C
質問 # 164
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?
- A. Updates that contain changes within the data are sent only when changes occur.
- B. Periodic updates include a full copy of the data that is subscribed to.
- C. Empty data subscriptions do not generate empty update notifications.
- D. The primary push update is sent immediately and cannot be delayed.
正解：B
解説：
Explanation
Periodic updates contain a full copy of the subscribed data element or table for all supported transport protocols

質問 # 165
An engineer is tasked with designing a dual BGP peering solution with a service provider. The design must meet these conditions:
* The routers will not learn any prefix with a subnet mask greater than /24.
* The routers will determine the routes to include in the routing table based on the length of the mask alone.
* The routers will make this selection regardless of the service provider configuration.
Which solution should the engineer include in the design?
- A. Use a route map and access list to block the desired networks, and apply the route map to BGP neighbors inbound.
- B. Use a route map and prefix list to block the desired networks, and apply the route map to BGP neighbors outbound.
- C. Use an IP prefix list to block the desired networks and apply the IP prefix list to BGP neighbors inbound.
- D. Use an IP prefix list to block the desired networks and apply the IP prefix list to BGP neighbors outbound.
正解：C

- A.
- B.
- C.
- D.
正解：B

- E. use R-PVSTP+
正解：B、C

質問 # 173 
Refer to the exhibit. A customer needs to apply QoS to the network management traffic passing through the GigabitEthernet0/2 interface. All eight queuing classes are in use, so the new requirement must be integrated into the existing policy. Which solution must the customer choose?
- A. Mark the traffic to DSCP CS4 and assign it to the SIGNALLING class. Then, prioritize traffic within the class.
- B. Mark traffic to DSCP CS5 and assign it to the SIGNALLING class. Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the SIGNALLING class.
- C. Mark the traffic to DSCP CS2 and assign it to the ROUTING class Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the ROUTING class
- D. Mark the traffic to DSCP CS6 and assign it to the ROUTING class Then, prioritize traffic within the class.
正解：C
質問 # 174

質問 # 175
An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network. The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same router levels for each protocol per interface. Which IS-IS design is required?
- A. single topology without enabling transition feature
- B. single topology with transition feature enabled
- C. multi topology without enabling transition feature
- D. multi topology with transition feature enabled
正解：B
解説：
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_isis/configuration/xe-3s/irs-xe-3s-book/ip6-route-isis-xe.html#GUID-04990BCF-8228-459E-AFAA-9FAF1E2136E9 For single-topology IS-IS IPv6, routers must be configured to run the same set of address families. IS-IS performs consistency checks on hello packets and will reject hello packets that do not have the same set of configured address families. For example, a router running IS-IS for both IPv4 and IPv6 will not form an adjacency with a router running IS-IS for IPv4 or IPv6 only. In order to allow adjacency to be formed in mismatched address-families network, the adjacency-check command in IPv6 address family configuration mode must be disabled.
