질문 # 123
A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?
정답：A
설명：
Explanation
using NBAR to identify application and bandwidth usage, then adjust existing QoS polices would be a more simple option. Of course, B is still ok if the network admin know all traffic and bandwidth consumption by other tools, say netflow.https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_nbar/configuration/15-mt/qos-nbar-15-mt-book/n

질문 # 124 
Refer to the exhibit A customer requires maximum uptime for the data plane between R1 and R3 running OSPF Which solution must the design include for high availability if the routing process on R2 requires maintenance?
정답：B
설명：
Graceful restart is the correct high-availability design when the routing process on an intermediate OSPF router must undergo maintenance while the data plane remains available. Cisco describes graceful restart as a mechanism that allows a restarting router to continue forwarding traffic while neighbors temporarily preserve adjacency and route information. In OSPF, helper-capable neighbors assist the restarting router by maintaining forwarding state during the restart interval, preventing unnecessary route withdrawal and reconvergence. BFD is a failure-detection mechanism, so it would actually accelerate detection of a failure rather than preserve the forwarding path during planned process maintenance. Nonstop forwarding must be enabled on the device performing the control-plane restart and supported by neighbors, but the broad answer choice that captures the required routing-protocol behavior across the design is graceful restart on the participating routers. Configuring it only on R1 and R3 or only on R3 would not support the R2 process maintenance scenario. Reference topics: OSPF graceful restart, NSF, helper mode, control-plane maintenance, data-plane availability.

질문 # 126 
Refer to the exhibit. An engineer is planning an IPv4 to IPv6 migration solution for a customer. The routers in the network can support IPv4 and IPv6, except for the DWDM routers. The DWDM routers provide a Layer 2 link in which the routers peer directly with each other across a DWDM circuit. The circuit also provides connectivity between the mail servers. Which IPv6 migration technique must the engineer deploy?
정답：D
설명：
Dual-stack is the correct IPv6 migration technique because the DWDM devices provide Layer 2 transport between routers that already support both IPv4 and IPv6. Layer 2 transport is generally transparent to IPv6 because it forwards Ethernet frames rather than participating in Layer 3 routing. The routers at the ends of the DWDM circuit can peer directly over the Layer 2 service and run IPv6 in parallel with IPv4, while mail servers can also retain IPv4 reachability during the migration. Cisco dual-stack migration guidance uses simultaneous IPv4 and IPv6 operation to support phased application and host transition with minimal tunneling overhead. 6to4, ISATAP, and 6rd are tunneling or transition mechanisms used when IPv6 islands must cross IPv4-only routed infrastructure. In this case, the limiting devices are in the transport layer and do not need to route IPv6. Deploying dual-stack on the capable routers and servers is simpler, more transparent, and avoids unnecessary encapsulation. Reference topics: IPv6 dual-stack migration, Layer 2 transparency, IPv6 over Ethernet, tunneling avoidance, phased migration.
