   Which LISP component decapsulates messages and forwards them to the map server responsible for the egress tunnel routers?

   • ARouter Locator
   • BMap Resolver
   • CProxy ETR
   • DIngress Tunnel Router

   Show answer

   Answer: B

   Explanation

   The function of the LISP MR is to accept encapsulated Map-Request messages from ingress tunnel routers (ITRs), decapsulate those messages, and then forward the messages to the MS responsible for the egress tunnel routers (ETRs) that are authoritative for the requested EIDs.

3. Question 473 · 1003 in bank

   An engineer must design a wireless network for a school system based on these requirements: ✑ The network must be able to triangulate client location based on RSSI. ✑ Each client must be able to sustain 5 Mbps of throughput at all times. ✑ Each classroom has up to 30 clients. ✑ Primary coverage is 5 GHz. Which design should be used?

   • APlace APs in a grid orientation throughout the building, located as close as possible to the center of each classroom.
   • BMount one AP in the center of each classroom.
   • CSpace APs evenly on both sides of the hallways.
   • DPlace APs near exterior walls and corners of the building, and fill in the center area with a staggered pattern.

   Show answer

   Answer: D

   Explanation

   For a location management deployment, the APs are laid out in a staggered pattern. Figure 3-5 shows a typical pattern. The staggered pattern allows for more accurate estimation of the location of a device. https://www.cisco.com/en/US/docs/solutions/Enterprise/Mobility/emob30dg/RFDesign.html

   What is one characteristic of VXLAN?

   • AIt supports a maximum of 4096 VLANs
   • BIt supports multitenant segments
   • CIt uses STP to prevent loops in the underlay network
   • DIt uses the Layer 2 header to transfer packets through the network underlay

   Show answer

   Answer: B

   Explanation

   A. It supports a maximum of 4096 VLANs (incorrect, supports 16 million segments) B. It supports multitenant segments (correct) C. It uses STP to prevent loops in the underlay network (incorrect, STP used in traditional networking with VLANs) D. It uses the Layer 2 header to transfer packets through the network underlay (incorrect, VxLAN transfers packets apart of the network OVERLAY)

   What is the function of vBond in a Cisco SD-WAN deployment?

   • Ainitiating connections with SD-WAN routers automatically
   • Bpushing of configuration toward SD-WAN routers
   • Conboarding of SD-WAN routers into the SD-WAN overlay
   • Dgathering telemetry data from SD-WAN routers

   Show answer

   Answer: C

   Explanation

   C (vBond not initia connection to vEdges automatically ) WAN Edge onboarding process Upon bootup, the WAN Edge device contacts the vBond orchestrator to establish a secure transient DTLS control connection.

   Select 2

   

   Refer to the exhibit. A network administrator configured RSPAN to troubleshoot an issue between switch 1 and switch2. The switches are connected using interface GigabitEthernet 1/1. An external packet capture device is connected to swich2 interface GigabitEthernet 1/2. Which two commands must be added to complete this configuration? (Choose two.)

   • Aswitch2(config-if)# switchport trunk allowed vlan 10,20,30,40,50,60,70-80
   • Bswitch2(config)# monitor session 1 source remote vlan 70 switch2(config)# monitor session 1 destination interface GigabitEthernet1/2
   • Cswitch1(config)# interface GigabitEthernet 1/1 switch1 (config-if)# switchport mode access switch1 (config-if)# switchport access vlan 10 switch2(config)# interface GigabitEthernet 1/1 switch2(config-if)# switchport mode access switch2(config-if)# switchport access vlan 10
   • Dswitch2(config)# monitor session 2 destination vlan 10
   • Eswitch2(config)# monitor session 1 source remote vlan 70 switch2(config)# monitor session 1 destination interface GigabitEthernet1/1

   Show answer

   Answer: AB

   Explanation

   Switch2 is not allowing VLAN 70 which is used on Switch1 for RSPAN so we must allow it -> Option A is correct (although it would not allow VLAN 81 to 90 to go through). “An external packet capture device is connected to switch2 interface GigabitEthernet1/2” so we must configure Gi1/2 as the destination port. For your information, this is how to configure Remote SPAN (RSPAN) feature on two switches. Traffic on FastEthernet0/1 of Switch 1 will be sent to Fa0/10 of Switch2 via VLAN 40. + Configure on both switches Switch1,2(config)#vlan 40 Switch1,2(config-vlan)#remote-span + Configure on Switch1 Switch1(config)# monitor session 1 source interface FastEthernet 0/1 Switch1(config)# monitor session 1 destination remote vlan 40 + Configure on Switch2 Switch2(config)#monitor session 5 source remote vlan 40 Switch2(config)# monitor session 5 destination interface FastEthernet 0/10

8. Question 478 · 1003 in bank

   Which function does a Cisco SD-Access extended node perform?

   • Aprovides fabric extension to nonfabric devices through remote registration and configuration
   • Bperforms tunneling between fabric and nonfabric devices to route traffic over unknown networks
   • Cused to extend the fabric connecting to downstream nonfabric enabled Layer 2 switches
   • Din charge of establishing Layer 3 adjacencies with nonfabric unmanaged node

   Show answer

   Answer: C

   Explanation

   An 'extended node' are Cisco switches from product lines that were not redesigned for SDA operation. As an example, the industrial ethernet product line (IE3K) Called extended because their functionality was "extended": -> they can be connected to Fabric Edge Nodes -> they can be managed by Cisco DNA Center -> they can participate in the SDA Fabric in a very limited way -> for example they don't build VXLAN tunnels -> they connect to the Fabric Edge Nodes using a 802.1q (VLAN) trunk port I guess the difference between A and C is that: A, with its phrasing, implies that 'extended' nodes are those nodes that make possible the integration of non-fabric nodes with the fabric using registraton and configuration. This is wrong because 'extended' nodes ARE BY THEMSELVES those non-fabric enabled nodes. C is correct because extended nodes allow the fabric to extend by connecting to them, non-fabric enabled nodes

9. Question 479 · 1003 in bank

   Which router is elected the IGMP Querier when more than one router is in the same LAN segment?

   • AThe router with the shortest uptime.
   • BThe router with the longest uptime.
   • CThe router with the highest IP address.
   • DThe router with the lowest IP address.

   Show answer

   Answer: D

   Explanation

   Query messages are used to elect the IGMP querier as follows: 1. When IGMPv2 devices start, they each multicast a general query message to the allsystems grou address of 224.0.0.1 with their interface address in the source IP address field of the message. 2. When an IGMPv2 device receives a general query message, the device compares the source IP address in the message with its own interface address. The device with the lowest IP address on the subnet is elected the IGMP querier. 3. All devices (excluding the querier) start the query timer, which is reset whenever a general query message is received from the IGMP querier. If the query timer expires, it is assumed that the IGMP querier has gone down, and the election process is performed again to elect a new IGMP querier.

10. Question 480 · 1003 in bank

    What is the function of the fabric control plane node in a Cisco SD-Access deployment?

    • AIt is responsible for policy application and network segmentation in the fabric.
    • BIt performs traffic encapsulation and security profiles enforcement in the fabric.
    • CIt holds a comprehensive database that tracks endpoints and networks in the fabric.
    • DIt provides integration with legacy nonfabric-enabled environments.

    Show answer

    Answer: C

    Explanation

    C. The control plane node’s database tracks all endpoints in the fabric site and associates the endpoints to fabric nodes, decoupling the endpoint IP address or MAC address from the location (closest router) in the network.
