Cisco 350-401 Online Questions & Answers

• Question 391:

  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 392:

  How does Cisco Express Forwarding switching differ from process switching on Cisco devices?

  A. Cisco Express Forwarding switching uses adjacency tables built by the CDP protocol, and process switching uses the routing table.
  B. Cisco Express Forwarding switching uses dedicated hardware processors, and process switching uses the main processor.
  C. Cisco Express Forwarding swithing saves memory by storing adjacency tables in dedicated memory on the line cards, and process switching stores all tables in the main memory.
  D. Cisco Express Forwarding switching uses a proprietary protocol based on IS-IS for MAC address lookup, and process switching uses the MAC address table.
  C. Cisco Express Forwarding swithing saves memory by storing adjacency tables in dedicated memory on the line cards, and process switching stores all tables in the main memory.

• Question 393:

  Refer to the exhibit.

  

  Which action does the Python script accomplish?

  A. connects to the device using Telnet and exports the routing table information
  B. connects to the device using SSH and exports the routing table information
  C. displays the output of the show command in an unformatted way
  D. displays the output of the show command in a formatted way
  B. connects to the device using SSH and exports the routing table information

• Question 394:

  What is the result of applying this access control list?

  ip access-list extended STATEFUL

  10 permit tcp any any established 20 deny ip any any

  A. TCP traffic with the URG bit set is allowed
  B. TCP traffic with the SYN bit set is allowed
  C. TCP traffic with the ACK bit set is allowed
  D. TCP traffic with the DF bit set is allowed
  C. TCP traffic with the ACK bit set is allowed

  ---

  Explanation

  The established keyword is only applicable to TCP access list entries to match TCP segments that have the ACK and/or RST control bit set (regardless of the source and destination ports), which assumes that a TCP connection has already been established in one direction only. Let's see an example below:

  

  Suppose you only want to allow the hosts inside your company to telnet to an outside server but not vice versa, you can simply use an "established" access-list like this: access-list 100 permit tcp any any established access-list 101 permit tcp any any eq telnet ! interface S0/0 ip access-group 100 in ip access-group 101 out

• Question 395:

  In a Cisco SD-Access wireless environment, which device is responsible for hosting the anycast gateway?

  A. fusion router
  B. control plane node
  C. fabric border node
  D. fabric edge node
  D. fabric edge node

  ---

  Explanation

  "...... Inter-VLAN traffic is attracted to the edge node because the AnyCast gateway for the end hosts resides there." Here is the link:

• Question 396:

  DRAG DROP

  Drag and drop the characteristics from the left onto the orchestration tools that they describe on the right.

  Select and Place:

  

  

• Question 397:

  In a Cisco DNA Center Plug and Play environment, why would a device be labeled unclaimed?

  A. The device has not been assigned a workflow.
  B. The device could not be added to the fabric.
  C. The device had an error and could not be provisioned.
  D. The device is from a third-party vendor.
  A. The device has not been assigned a workflow.

  ---

  Explanation

  Unclaimed--Device has not been provisioned.

  Planned--Device has been claimed but has not yet contacted the server.

  Onboarding--Device onboarding is in progress.

  Provisioned--Device is successfully onboarded and added to inventory.

  Error--Device had an error and could not be provisioned.

• Question 398:

  Why would a small or mid-size business choose a cloud solution over an on-premises solution?

  A. Cloud provides greater ability for customization than on-premises.
  B. Cloud provides more control over the implementation process than on-premises.
  C. Cloud provides lower upfront cost than on-premises.
  D. Cloud provides higher data security than on-premises.
  C. Cloud provides lower upfront cost than on-premises.

• Question 399:

  Which measurement is used from a post wireless survey to depict the cell edge of the access points?

  A. SNR
  B. Noise
  C. RSSI
  D. CCI
  C. RSSI

  ---

  Explanation

  Coverage defines the ability of wireless clients to connect to a wireless AP with a signal strength and quality high enough to overcome the effects of RF interference. The edge of the coverage for an AP is based on the signal strength and SNR measured as the client device moves away from the AP.

  The signal strength required for good coverage varies dependent on the specific type of client devices and applications on the network.

  To accommodate the requirement to support wireless Voice over IP (VoIP), refer to the RF guidelines specified in the Cisco 7925G Wireless IP Phone Deployment Guide. The minimum recommended wireless signal strength for voice applications is -67 dBm and the minimum SNR is 25 dB.

  The first step in the analysis of a post site survey is to verify the `Signal Coverage'. The signal coverage is measured in dBm. You can adjust the color-coded signal gauge to your minimum-allowed signal level to view areas where there are sufficient and insufficient coverage. The example in Figure 8 shows blue, green, and yellow areas in the map have signal coverage at -67 dBm or better. The areas in grey on the coverage maps have deficient coverage. Source from Cisco

  C. {"Make": Gocar, "Model": Zoom, "Features": Power Windows, Manual Drive, Auto AC}
  D. ("Make":[ "Gocar", "Model": "Zoom"], Features": ["Power Windows", "Manual Drive", "Auto AC"]}
  A. Make":`Gocar, "Model': "Zoom", "Features": ["Power Windows", "Manual Dnve", "Auto AC"]}
