Cisco 350-401 Online Questions & Answers

• Question 101:

  Refer to the exhibit. Which action resolves the EtherChannel issue between SW2 and SW3?

  

  A. Configure switchport mode trunk on SW2.
  B. Configure switchport nonegotiate on SW3
  C. Configure channel-group 1 mode desirable on both interfaces.
  D. Configure channel-group 1 mode active on both interfaces.
  C. Configure channel-group 1 mode desirable on both interfaces.

  Explanation

  SW2 is using PAgP and both members interface Gi0/0 and Gi0/1 are in state(I), it means they are not receiving any activity.

• Question 102:

  An engineer receives a report that an application exhibits poor performance. On the switch where the server is connected, this syslog message is visible: SW_MATM-4-MACFLAP_NOTIF: Host 0054.3962.7651 in vlan 14 is flapping between port Gi1/0/1 and port Gi1/0/2.

  What is causing the problem?

  A. undesirable load-balancing configuration on the switch
  B. invalid port channel configuration on the switch
  C. wrong SFP+ and cable connected between the server and the switch
  D. failed NIC on the server
  B. invalid port channel configuration on the switch

  ---

  Explanation

  If the EtherChannel has not been established (for some misconfiguration), and the switch still treats the ports as individual ports while the other end is already using them as a bundle We have MAC flapping...

• Question 103:

  In a high-density AP environment, which feature can be used to reduce the RF cell size and not demodulate radio packets above a given threshold?

  A. RX-SOP
  B. FRA
  C. 80211k
  D. RRM
  A. RX-SOP

• Question 104:

  Which option must be used to support a WLC with an IPv6 management address and 100 Cisco Aironet 2800 Series access points that will use DHCP to register?

• Question 105:

  What is a characteristic of Cisco DNA southbound APIs?

  A. implements monitoring by using the SOAP protocol
  B. enables orchestration and automation of network devices based on intent
  C. utilizes REST API
  D. simplifies management of network devices
  B. enables orchestration and automation of network devices based on intent

  ---

  Explanation

  outhbound is primarily aimed at non-Cisco "thirdparty" devices!

  Northbound: Discovery and management of the network over REST API Southbound: SDK integration into the DNA Center via device packs to support multivendor environment Eastbound: Event / Notification Handler Westbound: Integration of reporting, analysis, service management

• Question 106:

  Refer to the exhibit.

  

  An engineer must prevent the R6 loopback from getting into Area 2 and Area 3 from Area 0 Which action must the engineer take?

  A. Apply a fitter list inbound on R2 and R9
  B. Apply a filter list outbound on R3 and R7
  C. Apply a filter list outbound on R7 only.
  D. Apply a filter list inbound on R3 and R7
  B. Apply a filter list outbound on R3 and R7

  ---

  Explanation

  This question asks to prevent route advertised into Area 2 and Area 3 only. It does not ask to prevent route advertised into Area 0 so applying a filter list outbound on R3 and R7 would best fit the requirement.

• Question 107:

  What is the calculation that is used to measure the radiated power of a signal after it has gone through the radio, antenna cable, and antenna?

  A. EIRP
  B. mW
  C. dBm
  D. dBi
  A. EIRP

• Question 108:

  In a Cisco SD-Access network architecture, what is the role of the Fabric Edge Node?

  A. It manages endpoint to device relationships
  B. It connects external layer 3 networks to the SDA fabric
  C. It connects wired endpoints to the SDA fabric
  D. It connects wireless endpoints to the SDA fabric
  C. It connects wired endpoints to the SDA fabric

• Question 109:

  Refer to the exhibit.

  

  Router 1 is currently operating as the HSRP primary with a priority of 110 router1 fails and router2 take over the forwarding role.

  Which command on router1 causes it to take over the forwarding role when it return to service?

  A. standby 2 priority
  B. standby 2 timers
  C. standby 2 track
  D. standby 2 preempt
  D. standby 2 preempt

• Question 110:

  Refer to the Exhibit.

  

  An engineer is installing a new pair of routers in a redundant configuration. When checking on the standby status of each router the engineer notices that the routers are not functioning as expected.

  Which action will resolve the configuration error?

  A. configure matching hold and delay timers
  B. configure matching key-strings
  C. configure matching priority values
  D. configure unique virtual IP addresses
  D. configure unique virtual IP addresses

  ---

  Explanation

  The most situable for this question is D (configure unique virtual address) as is one of requirements for a group to work, as seeing in the image. The others are wrong for the following reason. (so Wrong based in the question) A) Not mandatory the timers must match to work on HSRP. on HSRP negotiation the active router will override the standby timers.

  https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9000/nb-06-cat-9k-stack-wp-cte-en.pdf B) On the image key string match so is not this reason HSRP cant be seen each other C) Wrong, priority is for selecing the active router, the best practice is should be different thus (WRONG) D) Different virtual Gateway configured on the same group number indeed will make HSRP routers negotiation fail for that group thus (CORRECT)
