Cisco 350-401 Online Practice Questions and Exam Preparation

Cisco 350-401 Online Questions & Answers

• Question 771:

  Which technology provides an overlay fabric to connect remote locations utilizing commodity data paths and improves network performance, boosts security, and reduces costs?

  A. InfiniBand
  B. VTEP
  C. SD-WAN
  D. VXLAN
  C. SD-WAN

• Question 772:

  Refer to the exhibit.

  

  Which password allows access to line con 0 for a username of "tommy" under normal operation?

  A. Cisco
  B. local
  C. 0 Cisco
  D. Tommy
  A. Cisco

  ---

  Explanation

  In this question, there are two different passwords for user "tommy": + In the TACACS+ server, the password is "Tommy"

  + In the local database of the router, the password is "Cisco".

  From the line "login authentication local" we know that the router uses the local database for authentication so the password should be "Cisco".

  Note: "... password 0 ..." here means unencrypted password.

• Question 773:

  A customer requests a network design that supports these requirements:

  1. FHRP redundancy

  2. multivendor router environment

  3. IPv4 and IPv6 hosts

  Which protocol does the design include?

  A. GLBP
  B. VRRP version 2
  C. VRRP version 3
  D. HSRP version 2
  C. VRRP version 3

  ---

  Explanation

  HSRP and GLBP are Cisco propietary, so they won't work in a multivendor setup. VRRPv3 us multivendor and supports IPv4 and 6.

• Question 774:

  Which method provides failure detection in BFD?

  A. short duration, high overhead
  B. short duration, low overhead
  C. long duration, high overhead
  D. long duration, low overhead
  B. short duration, low overhead

• Question 776:

  Which type of API enables Cisco Catalyst Center (formerly DNA Center) to focus on outcome instead of the individual steps that are required to achieve the outcome?

  A. southbound Multivendor Support
  B. westbound Integration
  C. northbound Intent
  D. eastbound Events and Notifications
  C. northbound Intent

• Question 777:

  Refer to the exhibit. An engineer troubleshoots connectivity issues with an application. Testing is performed from the server gateway, and traffic with the DF bit set is dropped along the path after increasing packet size. Removing the DF bit setting at the gateway prevents the packets from being dropped.

  What is the cause of this issue?

  

  A. PMTUD does not work due to ICMP Packet Too Big messages being dropped by an ACL
  B. The remote router drops the traffic due to high CPU load.
  C. The server should not set the DF bit in any type of traffic that is sent toward the network
  D. There is a CoPP policy in place protecting the WAN router CPU from this type of traffic
  C. The server should not set the DF bit in any type of traffic that is sent toward the network

• Question 778:

  Which template is used when multiple templates are grouped together to run in succession in Cisco DNA Center?

  A. composite
  B. regular
  C. project
  D. configuration
  A. composite

• Question 779:

  Refer to the exhibit.

  

  The control plane is heavily impacted after the CoPP configuration is applied to the router.

  Which command removal lessens the impact on the control plane?

  A. access-list 120 permit eigrp any host 224.0.0.10
  B. access-list 120 permit ospf any
  C. access-list 120 permit udp any any eq pim-auto-rp
  D. access-list 120 permit tcp any gt 1024 eq bgp log
  D. access-list 120 permit tcp any gt 1024 eq bgp log

• Question 780:

  In cisco SD_WAN, which protocol is used to measure link quality?

  A. OMP
  B. BFD
  C. RSVP
  D. IPsec
  B. BFD

  ---

  Explanation

  The BFD (Bidirectional Forwarding Detection) is a protocol that detects link failures as part of the Cisco SD-WAN (Viptela) high availability solution, is enabled by default on all vEdge routers, and you cannot disable it.
