Cisco CCNP Enterprise 350-401 Questions & Answers

• Question 201:

  Which three methods does Cisco DNA Center use to discover devices? (Choose three.)

  A. CDP

  B. SNMP

  C. LLDP

  D. Ping

  E. NETCONF

  F. specified range of IP addresses

  Correct Answer: ACF

  There are three ways for you to discover devices:

  1.

  Use Cisco Discovery Protocol (CDP) and provide a seed IP address.

  2.

  Specify a range of IP addresses. (A maximum range of 4096 devices is supported.)

  3.

  Use Link Layer Discovery Protocol (LLDP) and provide a seed IP address.

• Question 202:

  Which outbound access list, applied to the WAN interface of a router, permits all traffic except for http traffic sourced from the workstation with IP address 10.10.10.1?

  A. ip access-list extended 10 deny tcp host 10.10.10.1 any eq 80 permit ip any any

  B. ip access-list extended 200 deny tcp host 10.10.10.1 eq 80 any permit ip any any

  C. ip access-list extended NO_HTTP deny tcp host 10.10.10 1 any eq 80

  D. ip access-list extended 100 deny tcp host 10.10.10.1 any eq 80 permit ip any any

  Correct Answer: D

• Question 203:

  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

  Correct Answer: A

  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 204:

  Which command set configures RSPAN to capture outgoing traffic from VLAN 3 on interface GigabitEthernet 0/3 while ignoring other VLAN traffic on the same interface?

  A. monitor session 2 source interface gigabitethernet0/3 rx monitor session 2 filter vlan 3

  B. monitor session 2 source interface gigabitethernet0/3 rx monitor session 2 filter vlan 1 - 2, 4 - 4094

  C. monitor session 2 source interface gigabitethernet0/3 tx monitor session 2 filter vlan 3

  D. monitor session 2 source interface gigabitethernet0/3 tx monitor session 2 filter vlan 1- 2, 4 - 4094

  Correct Answer: C

• Question 205:

  A customer has 20 stores located throughout a city. Each store has a single Cisco AP managed by a central WLC. The customer wants to gather analytics for users in each store. Which technique supports these requirements?

  A. angle of arrival

  B. presence

  C. hyperlocation

  D. trilateration

  Correct Answer: B

• Question 206:

  What is an advantage of using BFD?

  A. It local link failure at layer 1 and updates routing table

  B. It detects local link failure at layer 3 and updates routing protocols

  C. It has sub-second failure detection for layer 1 and layer 3 problems.

  D. It has sub-second failure detection for layer 1 and layer 2 problems.

  Correct Answer: B

  BFD provides a low-overhead, short-duration method of detecting failures in the forwarding path between two adjacent routers, including the interfaces, data links, and forwarding planes. BFD is a detection protocol that you enable at the interface and routing protocol levels

• Question 207:

  A network engineer is designing a Qos policy for voice and video applications. Which software queuing feature provides strict-priority servicing?

  A. Class-Based Weighted Fair Queuing

  B. Link Fragmentation

  C. Low Larency Queuing

  D. Automatic Qos

  Correct Answer: C

• Question 208:

  Refer to the exhibit.

  

  An engineer must ensure that all traffic leaving AS 200 will choose Link 2 as the exit point. Assuming that all BGP neighbor relationships have been formed and that the attributes have not been changed on any of the routers.

  Which configuration accomplish task?

  A. R4(config-router)bgp default local-preference 200

  B. R3(config-router)neighbor 10.1.1.1 weight 200

  C. R3(config-router)bgp default local-preference 200

  D. R4(config-router)nighbor 10.2.2.2 weight 200

  Correct Answer: A

  Local preference is an indication to the AS about which path has preference to exit the AS in order to reach a certain network. A path with a higher local preference is preferred. The default value for local preference is 100.

  Unlike the weight attribute, which is only relevant to the local router, local preference is an attribute that routers exchange in the same AS. The local preference is set with the "bgp default local-preference value " command.

  In this case, both R3 and R4 have exit links but R4 has higher local-preference so R4 will be chosen as the preferred exit point from AS 200.

• Question 209:

  Refer to the exhibit.

  

  After configuring the BGP network, an engineer verifies that the path between server1 and server2 is functional, why did RouterSF choose the route from RouterDAL instead of the route from RouterCHI?

  A. BGP is not running on RouterCHI

  B. The Router-ID for Router DAL is lower than Router-ID for RouterCHI

  C. There is a static route in RouterSF for 10.0.0.0/24

  D. The route from RouterDAL has a lower MED

  Correct Answer: B

  All things being the same, we see that DAL has the lower router ID. C does not make sense, as the med value is stripped when crossing AS's and is only useable for iBGP peers.

• Question 210:

  What happens to the signal strength of an RF signal due to wave spreading?

  A. The signal strength of the RF signal will fall off equally near the transmitter and also farther away

  B. The signal strength of the RF signal will fall off quickly near the transmitter but more slowly farther away

  C. The signal strength of the RF signal will fall off slowly near the receiver and more quickly farther away

  D. The signal strength of the RF signal will fall off slowly near the transmitter but more quickly farther away

  Correct Answer: B
