Cisco 350-401 Online Questions & Answers

• Question 1181:

  A network administrator added a new spoke site with dynamic IP on the DMVPN network.

  Which configuration command passes traffic on the DMVPN tunnel from the spoke router?

  A. ip nhrp registration dynamic
  B. ip nhrp registration ignore
  C. ip nhrp registration no-registration
  D. ip nhrp registration no-unique
  D. ip nhrp registration no-unique

  ---

  Explanation

  "ip nhrp registration no-unique": allow the client to not set the unique flag in the NHRP packets. This is useful when a station has a dynamic IP address that could change over time.

• Question 1182:

  What is the measure of the difference between the received signal and the noise floor in a wireless environment?

  A. XOR
  B. RSSI
  C. RRM
  D. SNR
  D. SNR

• Question 1183:

  An engineer must configure GigabitEthernet 0/0 for VRRP group 65. The rouler must assume the primary rote when it has the highest priority in the group.

  Which command set must be applied?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

• Question 1184:

  How is 802.11 traffic handled in a fabric-enabled SSID?

  A. centrally switched back to WLC where the user traffic is mapped to a VXLAN on the WLC
  B. converted by the AP into 802.3 and encapsulated into VXLAN
  C. centrally switched back to WLC where the user traffic is mapped to a VLAN on the WLC
  D. converted by the AP into 802.3 and encapsulated into a VLAN
  B. converted by the AP into 802.3 and encapsulated into VXLAN

  ---

  Explanation

  Fabric AP communicates with fabric WLC using capwap for control plnae comms ony. To communicate with the SD-Access fabric, the AP will use vxlan encapsulation.

• Question 1185:

  While configuring an IOS router for HSRP with a virtual IP of 10.1.1.1, an engineer sees this log message.

  Jan 1 12:12:12.111 : %HSRP-4-DIFFVIP1: GigabitEthernet0/0 Grp 1 active routers virtual IP address 10.1.1.1 is different to the locally configured address 10.1.1.25

  Which configuration change must the engineer make?

  A. Change the HSRP group configuration on the remote router to 1.
  B. Change the HSRP group configuration on the local router to 1.
  C. Change the HSRP virtual address on the remote router to 10.1.1.1.
  D. Change the HSRP virtual address on the local router to 10.1.1.1.
  D. Change the HSRP virtual address on the local router to 10.1.1.1.

  ---

  Explanation

  Syslog points to local router having VIP ip 10.1.1.25, and remote router in g0/0 interface having 10.1.1.1. We want latter to all routers in HSRP so we need to configure local router, hence B.

  "is different to the locally configured..."

• Question 1186:

  What is one characteristic of VXLAN?

  A. It supports a maximum of 4096 VLANs.
  B. It supports multitenant segments.
  C. It uses STP to prevent loops in the underlay network.
  D. It uses the Layer 2 header to transfer packets through the network underlay.
  B. It supports multitenant segments.

• Question 1187:

  DRAG DROP

  Drag and drop the characteristics from the left onto the deployment models on the right.

  Select and Place:

  

  

• Question 1188:

  Which DNS lookup does an access point perform when attempting CAPWAP discovery?

  A. CISCO-DNA-CONTROlLLER.local
  B. CAPWAP-CONTROLLER.local
  C. CISCO-CONTROLLER.local
  D. CISCO-CAPWAP-CONTROLLER.local
  D. CISCO-CAPWAP-CONTROLLER.local

• Question 1189:

  Refer to the exhibit.

  

  Rapid PVST+ is enabled on all switches.

  Which command set must be configured on switch1 to achieve the following results on port fa0/1?

  1. When a device is connected, the port transitions immediately to a forwarding state.

  2. The interface should not send or receive BPDUs.

  3. If a BPDU is received, it continues operating normally.

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  ---

  Explanation

  BPDU filtering allows you to avoid transmitting BPDUs on PortFast-enabled ports that are connected to an end system. When you enable PortFast on the switch, spanning tree places ports in the forwarding state immediately, instead of going through the listening, learning, and forwarding states.

  By default, spanning tree sends BPDUs from all ports regardless of whether PortFast is enabled. BDPU filtering is on a per-switch basis; after you enable BPDU filtering, it applies to all PortFast-enabled ports on the switch.

• Question 1190:

  When a wireless client roams between two different wireless controllers, a network connectivity outage is experience for a period of time.

  Which configuration issue would cause this problem?

  A. Not all of the controllers in the mobility group are using the same mobility group name.
  B. Not all of the controllers within the mobility group are using the same virtual interface IP address.
  C. All of the controllers within the mobility group are using the same virtual interface IP address.
  D. All of the controllers in the mobility group are using the same mobility group name.
  B. Not all of the controllers within the mobility group are using the same virtual interface IP address.

  ---

  Explanation

  A prerequisite for configuring Mobility Groups is "All controllers must be configured with the same virtual interface IP address". If all the controllers within a mobility group are not using the same virtual interface, inter-controller roaming may appear to work, but the handoff does not complete, and the client loses connectivity for a period of time. -> Answer B is correct.
