Cisco 350-401 Online Questions & Answers

• Question 971:

  What does a YANG model provide?

  A. standardized data structure independent of the transport protocols
  B. creation of transport protocols and their interaction with the OS
  C. user access to interact directly with the CLI of the device to receive or modify network configurations
  D. standardized data structure that can be used only with NETCONF or RESTCONF transport protocols
  A. standardized data structure independent of the transport protocols

  ---

  Explanation

  YANG is a standards-based, extensible data modeling language that is used to model the configuration and operational state data, remote procedure calls (RPCs), and server event notifications of network devices. The NETMOD working group in the IETF originally designed YANG to model network management data and to provide a standard for the content layer of the Network Configuration Protocol (NETCONF) model. However, YANG is protocol independent, and YANG data models can be used independent of the transport or RPC protocol and can be converted into any encoding format supported by the network configuration protocol.

  A. Installed as an application on an already installed operating system.
  B. Runs directly on a physical server and includes its own operating system.
  C. Supports over-allocation of physical resources.
  D. Also referred to as a "bare metal hypervisor" because it sits directly on the physical server.

• Question 977:

  Refer io me exhibit.

  

  An engineer configures the trunk and proceeds to configure an ESPAN session to monitor VLANs10. 20. and 30.

  Which command must be added to complete this configuration?

  A. Device(config.mon.erspan.stc)# no filter vlan 30
  B. Devic(config.mon.erspan.src-dst)# no vrf 1
  C. Devic(config.mon.erspan.src-dst)# erspan id 6
  D. Device(config.mon-erspan.Src-dst)# mtu 1460
  A. Device(config.mon.erspan.stc)# no filter vlan 30

• Question 979:

  Refer to the exhibit.

  An engineer attempts to configure a router on a stick to route packets between Clients, Servers, and Printers; however, initial tests show that this configuration is not working.

  Which command set resolves this issue?

  

  

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

  ---

  Explanation

  We must reconfigure the IP address after assigning or removing an interface to a VRF. Otherwise that interface does not have an IP address.

• Question 980:

  Refer to the exhibit.

  

  An engineer configures VRRP and issues to show commands to verify operation. What does the engineer confirm about VRRP group 1 from the output?

  A. Communication between VRRP members is encrypted using MD5
  B. If R1 reboot, R2 becomes the master virtual router until R2 reboots
  C. There is no route to 10.10.1.1/32 in R2's routing table
  D. R1 is master if 10.10.1.1/32 is in its routing table
  D. R1 is master if 10.10.1.1/32 is in its routing table

  Explanation

  R1 is primary if 10.10.1.1/32 is in its routing table. -> because of track 20 command
