Cisco 350-401 Online Questions & Answers

• Question 931:

  DRAG DROP

  An engineer must create a script to append and modify device entries in a JSON-formatted file. The script must work as follows:

  1. Until interrupted from the keyboard, the script reads in the hostname of a device, its management IP address, operating system type, and CLI remote access protocol.

  2. After being interrupted, the script displays the entered entries and adds them to the JSON-formatted file,replacing existing entries whose hostname matches.

  The contents of the JSON-formatted file are as follows:

  {

  "examplerouter":{

  "ip":"203.0.113.1",

  "os":"ios-xe",

  "protocol":"ssh"

  },

  ...

  }

  Drag and drop the statements onto the blanks within the code to complete the script. Not all options are used.

• Question 932:

  Wireless users report frequent disconnections from the wireless network. While troubleshooting, a network engineer finds that after the user is disconnected, the connection re-establishes automatically without any input required. The engineer also notices these message logs:

  AP 'AP2' is down. Reason: Radio channel set. 6:54:04 PM AP 'AP4' is down. Reason: Radio channel set. 6:44:49 PM AP 'AP7' is down. Reason: Radio channel set.

  6:34:32 PM Which action reduces the user impact?

  A. increase the AP heartbeat timeout
  B. increase BandSelect
  C. enable coverage hole detection
  D. increase the dynamic channel assignment interval
  D. increase the dynamic channel assignment interval

  ---

  Explanation

  These message logs inform that the radio channel has been reset (and the AP must be down briefly). With dynamic channel assignment (DCA), the radios can frequently switch from one channel to another but it also makes disruption. The default DCA interval is 10 minutes, which is matched with the time of the message logs. By increasing the DCA interval, we can reduce the number of times our users are disconnected for changing radio channels.

• Question 933:

  Which two commands must be added to complete this confiquration? (Choose two.)

  A. switch2(config)# monitor session 2 destination vlan 10
  B. switch1(config)# interface GigabitEthernet 1/1 switch1(confia-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
  C. switch2(config)# monitor session 1 source remote vlan 70 switch2(config)# monitor session 1 destination interface GigabitEthernet1/1
  D. switch2(config-if)# switchport trunk allowed vlan 10,20,30,40,50,60,70-80
  E. switch2(config)# monitor session 1 source remote vlan 70 switch2(confia)# monitor session 1 destination interface GigabitEthernet1/2
  D. switch2(config-if)# switchport trunk allowed vlan 10,20,30,40,50,60,70-80
  E. switch2(config)# monitor session 1 source remote vlan 70 switch2(confia)# monitor session 1 destination interface GigabitEthernet1/2

• Question 934:

  Refer to the exhibit.

  

  Which action must be performed to allow RESTCONF access to the device?

  A. Enable the NETCONF service.
  B. Enable the SSH service.
  C. Enable the IOX service.
  D. Enable the HTTPS service.
  D. Enable the HTTPS service.

  ---

  Explanation

  RESTCONF runs over HTTPS. The following commands must be enabled to support RESTCONF over port 443:

  ip http secure-server

• Question 935:

  Which solution supports end to end line-rate encryption between two sites?

  A. IPsec
  B. TrustSec
  C. MACseC
  D. GRE
  A. IPsec

• Question 936:

  Which of the following statements are true regarding the Link Management Protocol (LMP) when used in the Cisco Stackwise virtual link? (Choose two.)

  A. It determines the switch priority.
  B. It negotiates the version of the virtual header
  C. It verifies link integrity via bidirectional forwarding
  D. It performs auto discovery of other active Stackwise switches
  B. It negotiates the version of the virtual header
  C. It verifies link integrity via bidirectional forwarding

  ---

  Explanation

  The Link Management Protocol (LMP) is activated on each link of the StackWise Virtual link as soon as it is brought up online. The LMP performs the following functions:

  1. Verifies link integrity by establishing bidirectional traffic forwarding, and rejects any unidirectional links 2. Exchanges periodic hellos to monitor and maintain the health of the links

  3. Negotiates the version of StackWise Virtual header between the switches StackWise Virtual link role resolution

• Question 937:

  What is required for a virtual machine to run?

  A. a Type 1 hypervisor and a host operating system
  B. a hypervisor and physical server hardware
  C. only a Type 1 hypervisor
  D. only a Type 2 hypervisor
  B. a hypervisor and physical server hardware

• Question 938:

  Refer to the exhibit.

  

  

  Which HTTP JSON response does the Python code output give?

  A. NameError: name 'json' is not defined
  B. KeyError 'kickstart_ver_str'
  C. 7.61
  D. 7.0(3)I7(4)
  D. 7.0(3)I7(4)

• Question 939:

  When does a stack master lose its role?

  A. When the priority value of a stack member is changed to a higher value
  B. when a switch with a higher priority is added to the stack
  C. when the stack master is reset
  D. when a stack member fails
  C. when the stack master is reset

  ---

  Explanation

  A stack master retains its role unless one of these events occurs:

  1. The switch stack is reset.* 2. The stack master is removed from the switch stack.

  3. The stack master is reset or powered off.

  4. The stack master fails.

  5. The switch stack membership is increased by adding powered-on standalone switches or switch stacks.*

  In the events marked by an asterisk (*), the current stack master might be re-elected based on the listed factors.

  When you power on or reset an entire switch stack, some stack members might not participate in the stack master election. Stack members that are powered on within the same 20-second time frame participate in the stack master election and have a chance to become the stack master. Stack members that are powered on after the 20-second time frame do not participate in this initial election and become stack members. All stack members participate in re-elections. For all powering considerations that affect stack-master elections, see the "Switch Installation" chapter in the hardware installation guide. The new stack master becomes available after a few seconds. In the meantime, the switch stack uses the forwarding tables in memory to minimize network disruption. The physical interfaces on the other available stack members are not affected during a new stack master election and reset. After a new stack master is elected and the previous stack master becomes available, the previous stack master does not resume its role as stack master. As described in the hardware installation guide, you can use the Master LED on the switch to see if the switch is the stack master.
