Cisco CCNP 350-401 Questions & Answers

• Question 1071:

  Which two descriptions of FlexConnect mode for Cisco APs are true? (Choose two.)

  A. APs that operate in FlexConnect mode cannot detect rogue APs.

  B. When connected to the controller, FlexConnect APs can tunnel traffic back to the controller.

  C. FlexConnect mode is used when the APs are set up in a mesh environment and used to bridge between each other.

  D. FlexConnect mode is a feature that is designed to allow specified CAPWAP-enabled APs to exclude themselves from managing data traffic between dents and infrastructure.

  E. FlexConnect mode is a wireless solution for branch office and remote office deployments.

  Correct Answer: BE

  A FlexConnect AP can, on a per-WLAN basis, either tunnel client data in CAPWAP to the controller (called Central Switching), or have client data egress at the AP's LAN port (called Local Switching). With Locally Switched WLANs, the AP can tag client traffic in separate VLANs, to segregate the traffic from its management interface.

• Question 1073:

  Which LISP infrastructure device provides connectivity between non-sites and LISP sites by receiving non-LISP traffic with a LISP site destination?

  A. PETR

  B. PITR

  C. map resolver

  D. map server

  Correct Answer: B

  Proxy ingress tunnel router (PITR): answer 'PETR' PITR is an infrastructure LISP network entity that receives packets from non-LISP sites and encapsulates the packets to LISP sites or natively forwards them to non-LISP sites.

• Question 1074:

  What are two common sources of interface for WI-FI networks? (Choose two.)

  A. radar

  B. LED lights

  C. rogue AP

  D. conventional oven

  E. fire alarm

  Correct Answer: AC

  It includes many different types of radio communication, such as low-frequency radio, AM radio, shortwave radio, television, FM radio, microwave, and radar. The microwave category also contains the two main frequency ranges that are used for wireless LAN communication: 2.4 and 5 GHz.

• Question 1075:

  In OSPF, which LAS type is responsible for pointing to the ASBR router?

  A. type 1

  B. type 2

  C. type 3

  D. type 4

  Correct Answer: D

• Question 1076:

  At which Layer does Cisco DNA Center support REST controls?

  A. EEM applets or scripts

  B. Session layer

  C. YMAL output from responses to API calls

  D. Northbound APIs

  Correct Answer: D

• Question 1077:

  Which statement about agent-based versus agentless configuration management tools is true?

  A. Agentless tools require no messaging systems between master and slaves.

  B. Agentless tools use proxy nodes to interface with slave nodes.

  C. Agent-based tools do not require a high-level language interpreter such as Python or Ruby on slave nodes.

  D. Agent-based tools do not require installation of additional software packages on the slave nodes.

  Correct Answer: A

• Question 1078:

  Which OSPF networks types are compatible and allow communication through the two peering devices?

  A. broadcast to nonbroadcast

  B. point-to-multipoint to nonbroadcast

  C. broadcast to point-to-point

  D. point-to-multipoint to broadcast

  Correct Answer: A

  The following different OSPF types are compatible with each other:

  + Broadcast and Non-Broadcast (adjust hello/dead timers) + Point-to-Point and Point-to-Multipoint (adjust hello/dead timers) Broadcast and Non-Broadcast networks elect DR/BDR so they are compatible. Point-topoint/ multipoint do not elect DR/BDR so they are compatible.

• Question 1079:

  What is the structure of a JSON web token?

  A. three parts separated by dots header payload, and signature

  B. header and payload

  C. three parts separated by dots version header and signature

  D. payload and signature

  Correct Answer: A

  JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is

  digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA. JSON Web Tokens are composed of three parts, separated by a dot (.): Header, Payload, Signature. Therefore,

  a JWT typically looks like the following:

  xxxxx.yyyyy.zzzzz

  The header typically consists of two parts: the type of the token, which is JWT, and the signing algorithm being used, such as HMAC SHA256 or RSA. The second part of the token is the payload, which contains the claims. Claims are

  statements about an entity (typically, the user) and additional data. To create the signature part you have to take the encoded header, the encoded payload, a secret, the algorithm specified in the header, and sign that.

• Question 1080:

  A response code of 404 is received while using the REST API on Cisco UNA Center to POST to this URI.

  /dna/intent/api/v1 /template-programmer/project

  What does the code mean?

  A. The client made a request a resource that does not exist.

  B. The server has not implemented the functionality that is needed to fulfill the request.

  C. The request accepted for processing, but the processing was not completed.

  D. The POST/PUT request was fulfilled and a new resource was created, Information about the resource is in the response body.

  Correct Answer: A

  The 404 (Not Found) error status code indicates that the REST API can't map the client's URI to a resource but may be available in the future. Subsequent requests by the client are permissible. Reference: https://restfulapi.net/http-status-codes/
