Cisco 350-401 Online Questions & Answers

• Question 1331:

  What is the difference in dBm when an AP power increases from 25 mW to 100mW?

  A. 75dBm
  B. 150dBm
  C. 6dBm
  D. 125dBm
  C. 6dBm

• Question 1332:

  Which function is performed by vSmart in the Cisco SD-WAN architecture?

  A. distribution of centralized policies
  B. execution of localized policies
  C. redistribution between OMP and other routing protocols
  D. facilitation of NAT detection and traversal
  A. distribution of centralized policies

• Question 1333:

  If the noise floor is -90 dBm and the wireless client is receiving a signal of -75 dBm, what is the SNR?

  A. 15
  B. 1.2
  C. -165
  D. 83
  A. 15

  ---

  Explanation

  There is obviously a typo here, you cant go to the + range.. Maximum achievable strength is -30dbm. The question should say -75, not 75.

• Question 1334:

  When reason could cause an OSPF neighborship to be in the EXSTART/EXCHANGE state?

  A. Mismatched OSPF network type
  B. Mismatched areas
  C. Mismatched MTU size
  D. Mismatched OSPF link costs
  C. Mismatched MTU size

  Explanation

  When OSPF adjacency is formed, a router goes through several state changes before it becomes fully adjacent with its neighbor. The states are Down -> Attempt (optional) -> Init -> 2-Way -> Exstart -> Exchange -> Loading -> Full. Short descriptions about these states are listed below:

  Down: no information (hellos) has been received from this neighbor.

  Attempt: only valid for manually configured neighbors in an NBMA environment. In Attempt state, the router sends unicast hello packets every poll interval to the neighbor, from which hellos have not been received within the dead interval.

  Init: specifies that the router has received a hello packet from its neighbor, but the receiving router's ID was not included in the hello packet 2-Way: indicates bi-directional communication has been established between two routers.

  Exstart: Once the DR and BDR are elected, the actual process of exchanging link state information can start between the routers and their DR and BDR. Exchange: OSPF routers exchange database descriptor (DBD) packets

  Loading: In this state, the actual exchange of link state information occurs

  Full: routers are fully adjacent with each other (Reference:

  http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f0e.shtml)

  Neighbors Stuck in Exstart/Exchange State the problem occurs most frequently when attempting to run OSPF between a Cisco router and another vendor's router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces don't match.

• Question 1335:

  DRAG DROP

  Drag and drop the characteristics from the left onto the correct infrastructure deployment types on the right.

  Select and Place:

  

  

• Question 1336:

  

  Refer to the exhibit. Router R2 should be learning the route for 10.123.187.0/24 via EIGRP.

  Which action resolves the issue without introducing more issues?

  A. Remove route redistribution in R2 for this route in OSPF.
  B. Use distribute-list to modify the route as an internal EIGRP route.
  C. Redistribute the route in EIGRP with metric, delay, and reliability.
  D. Use distribute-list to filter the external routes in OSPF.
  A. Remove route redistribution in R2 for this route in OSPF.

• Question 1337:

  Refer to the exhibit.

  

  An engineer attempts to bundle interface GiO/0 into the port channel, but it does not function as expected.

  Which action resolves the issue?

  A. Configure channel-group 1 mode active on interface Gi0/0.
  B. Configure no shutdown on interface Gi0/0.
  C. Enable fast LACP PDUs on interface Gi0/0.
  D. Set LACP max-bundle to 2 on interface Port-channel1.
  D. Set LACP max-bundle to 2 on interface Port-channel1.

  ---

  Explanation

  If we only have 2 interfaces in Port-channel, then in the display you will see "hot-sby" only if the command (config-if)#lacp max-bundle is 1 is executed on Po1. If we then configure the respective port as "Active", it remains unbundled.

• Question 1338:

  If a client's radio device receives a signal strength of -67 dBm and the noise floor is -85 dBm, what is the SNR value?

  A. 15 dB
  B. 16 dB
  C. 18 dB
  D. 20 dB
  C. 18 dB

  ---

  Explanation

  -67 - (-85)=18

• Question 1339:

  Where are operations related to software images located in the Cisco DNA Center GUI?

  A. Services
  B. Provisioning
  C. Assurance
  D. Design
  D. Design

  ---

  Explanation

  The following are some of the Cisco DNA [design] tools:

  1. Network Hierarchy:

  2. Network Settings:

  3. Image Repository:

  4. Network Profiles:

• Question 1340:

  Refer to the exhibit.

  What is the result of the API request?

  

  A. The "params" variable sends data fields to the network appliance.
  B. The native interface information is read from the network appliance.
  C. The Information for all interfaces is read from the network appliance.
  D. The "params" variable reads data fields from the network appliance
  C. The Information for all interfaces is read from the network appliance.
