Cisco 350-401 Online Practice Questions and Exam Preparation

Cisco 350-401 Online Questions & Answers

• Question 801:

  How are map-register messages sent in a LISP deployment?

  A. egress tunnel routers to map resolvers to determine the appropriate egress tunnel router
  B. ingress tunnel routers to map servers to determine the appropriate egress tunnel router
  C. egress tunnel routers to map servers to determine the appropriate egress tunnel router
  D. ingress tunnel routers to map resolvers to determine the appropnate egress tunnel router
  C. egress tunnel routers to map servers to determine the appropriate egress tunnel router

  ---

  Explanation

  During operation, an Egress Tunnel Router (ETR) sends periodic Map-Register messages to all its configured map servers.

• Question 802:

  How does IGMP function with multicast routing and PIM?

  A. IGMP is enabled automatically when multicast routing and PIM are configured on a router
  B. IGMP is incompatible with multicast routing
  C. IGMP is incompatible with PIM
  D. IGMP must be enabled manually when multicast routing and PIM are configured on a router.
  A. IGMP is enabled automatically when multicast routing and PIM are configured on a router

• Question 803:

  Which measure is used by an NTP server to indicate its closeness to the authoritative time source?

  A. time zone
  B. hop count
  C. stratum
  D. latency
  C. stratum

  ---

  Explanation

  NTP uses a stratum to describe the distance between a network device and an authoritative time source: A stratum 1 time server is directly attached to an authoritative time source (such as a radio or atomic clock or a GPS time source)

• Question 804:

  How is a data modeling language used?

  A. To enable data to be easily structured, grouped validated, and replicated
  B. To represent finite and well-defined network elements that cannot be changed.
  C. To model the flows of unstructured data within the infrastructure.
  D. To provide human readability to scripting languages
  A. To enable data to be easily structured, grouped validated, and replicated

  Explanation

  Customer needs are fast evolving. Typically, a network center is a heterogenous mix of various devices at multiple layers of the network. Bulk and automatic configurations need to be accomplished. CLI scraping is not flexible and optimal. Re-writing scripts many times, even for small configuration changes is cumbersome. Bulk configuration changes through CLIs are error-prone and may cause system issues. The solution lies in using data models-a programmatic and standards-based way of writing configurations to any network device, replacing the process of manual configuration. Data models are written in a standard, industry-defined language. Although configurations using CLIs are easier (more human-friendly), automating the configuration using data models results in scalability.

• Question 805:

  Refer to the exhibit.

  

  Hosts PC1 PC2 and PC3 must access resources on Serve 1. An engineer configures NAT on Router R1 1e enable the communication and enters the show command to verify operation.

  Which IP address is used by the hosts when they communicate globally to Server1?

  A. 155.1.1.1
  B. randorm addresses in the 155.1.1.0/24 range
  C. their own address in the 10.10.10.0/24 rance
  D. 155.1.1.5
  A. 155.1.1.1

  ---

  Explanation

  from inside host perspective the global address is 15.1.1.1

• Question 806:

  Refer to the exhibit.

  

  An engineer builds an EEM script to apply an access list.

  Which statement must be added to complete the script?

  A. event none
  B. action 2.1 cli command "ip action 3.1 ell command 101''
  C. action 6.0 ell command ''ip access-list extended 101''
  D. action 6.0 cli command ''ip access-list extended 101"
  A. event none

  ---

  Explanation

  The applet is missing the trigger event configuration. In this case there is no trigger event, so none must be selected. The access list is already configured, the applet only needs to apply it.

  event manager applet Block_Users

  event none

  action 1.0 cli command "enable"

  action 2.0 cli command "configure terminal" action 3.0 cli command "interface GigabitEthernet1"

  action 4.0 cli command "ip access-group 101 in" action 5.0 cli command "ip access-group 101 out"

  action 7.0 cli command "end"

• Question 807:

  An engineer runs the code against an API of Cisco DMA Center, and the platform returns this output.

  What does the response indicate?

  

  A. The authentication credentials are incorrect.
  B. The URl string is incorrect.
  C. The Cisco DNA Center API port is incorrect.
  D. The HTTP method is incorrect.
  D. The HTTP method is incorrect.

  https://developer.mozilla.org/en-US/docs/Web/HTTP/Status

  Invalid authentication credentials would return code 401

• Question 808:

  DRAG DROP

  Drag and drop the characteristics from the left onto the protocols they apply to on the right?

  Select and Place:

  

  

• Question 809:

  Refer to the exhibit.

  

  The OSPF neighborship fails between two routers.

  What is the cause of this issue?

  A. The OSPF router ID is missing on this router.
  B. The OSPF process is stopped on the neighbor router.
  C. There is an MTU mismatch between the two routers.
  D. The OSPF router ID is missing on the neighbor router.
  C. There is an MTU mismatch between the two routers.

  Explanation

  Stuck in ExStart and jumbo points to MTU.

  cisco_R2(config-subif)#do debug ip osp adj OSPF adjacency debugging is on

  cisco_R2(config-subif)#ip mtu 1111 <<<<<<<<<<<<<<<< cisco_R2(config-subif)#

  cisco_R2(config-subif)#

  cisco_R2(config-subif)#do clear ip ospf

  !!!debug shows this:
