Answer Description Explanation: https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/qos/vEdge-20-x/qosbook/ forwarding-qos.html On Cisco vEdge devices and Cisco IOS XE SD-WAN devices, each interface has eight queues, which are numbered 0 to 7. Queue 0 is reserved, and is used for both control traffic and low-latency queuing (LLQ) traffic. For LLQ, any class that is mapped to queue 0 must also be configured to use LLQ. Queues 1 to 7 are available for data traffic, and the default scheduling for these seven queues is weighted round-robin (WRR). For these queues, you can define the weighting according to the needs of your network. When QoS is not configured for data traffic, queue 2 is the default queue.
Question # 2 Which two functions is the Cisco SD-Access Edge Node responsible for? (Choose two.)
Act as anycast layer 3 gateway
Advertise EID subnets
Map users to virtual network
Act as LISP proxy tunnel router
Route and transport IP traffic
Click for Answer
Act as anycast layer 3 gateway
Map users to virtual network
Question # 3 Refer to the exhibit.
An architect is designing a network for a customer supporting a Wake-on-LAN application. Which solution must the architect choose?
IP directed-broadcasts on R1
spanning-tree uplinkfast on SW1
spanning-tree uplinkfast on SW2
IP directed-broadcasts on R2
Click for Answer
IP directed-broadcasts on R2
Answer Description Explanation: "IP directed broadcast" must be supported on the last router to the destination subnet. Since the sleeping PC's dont have IP adresses, the machines must be calles awake by broadcast that behaves like an unicast untill they reach the destination network. There the directed broadcast is handled like a proper broadcast to wake all WOL machines. https://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/91672- catl3-wol-vlans.html
Question # 4
Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time. Which solution must the design include?
both routers running EIGRP
one router running OSPFv2 and other OSPF v3
one router running ISIS and other OSPF v3
both routers running OSPFv2
Click for Answer
both routers running EIGRP
Answer Description Explanation: EIGRP has a function called "EIGRP Ipv6" (But that can still be called "EIGRP")
Question # 5 An engineer is designing a network for a customer running a wireless network with a common VLAN for all APs. The customer is experiencing unicast flooding in the Layer 2 network between the aggregation and access layers. The customer wants to reduce the flooding and improve convergence time. Which solution meets these requirements?
Migrate all APs to a common Layer 2 access layer switch and run Layer 3 from the aggregation layer to all remaining access layer switches.
Align HSRP primary and STP root bridges and reduce ARP timers to match CAM timers on the aggregation layer switches.
Migrate to a Layer 3 access campus design if the APs can run on separate VLANs.
Align HSRP primary and STP root bridges if the APs cannot run on separate VLANs.
Click for Answer
Align HSRP primary and STP root bridges if the APs cannot run on separate VLANs.
