  A. The TLS certificate of DNA Center is invalid
  B. The username or the password is incorrect
  C. The "dna-center" hostname cannot be resolved to an IP address
  D. The authentication URL is incorrect
  B. The username or the password is incorrect

• Question 364:

  An engineer must design a wireless network for a school system based on these requirements:

  1. The network must be able to triangulate client location based on RSSI.

  2. Each client must be able to sustain 5 Mbps of throughput at all times.

  3. Each classroom has up to 30 clients.

  4. Primary coverage is 5 GHz.

  Which design should be used?

  A. Place APs in a grid orientation throughout the building, located as close as possible to the center of each classroom.
  B. Mount one AP in the center of each classroom.
  C. Space APs evenly on both sides of the hallways.
  D. Place APs near exterior walls and corners of the building, and fill in the center area with a staggered pattern.
  D. Place APs near exterior walls and corners of the building, and fill in the center area with a staggered pattern.

  Explanation

  I have seen this at many conferences and webinars - If triangulation is an important factor: line the perimeter with APs (with flat panel antennas). In fact next time you are at Cisco Live, you will see this design all around the perimeter of the venue...

• Question 365:

  A customer wants to use a single SSID to authenticate loT devices using different passwords. Which Layer 2 security type must be configured in conjunction with Cisco ISE to achieve this requirement?

  A. Fast Transition
  B. Central Web Authentication
  C. Cisco Centralized Key Management
  D. Identity PSK
  D. Identity PSK

  ---

  Explanation

  With the advent of internet of things, the number of devices that connect to the internet is increased multifold. Not all of these devices support 802.1x supplicant and need an alternate mechanism to connect to the internet. One of the security mechanisms, WPA-PSK could be considered as an alternative. With the current configuration, the pre-shared-key is the same for all clients that connect to the same WLAN. In certain deployments such as Educational Institutions, this results in the key being shared to unauthorized users resulting in security breach. Therefore, above mentioned and other requirements lead to the need for provisioning unique pre-shared keys for different clients on a large scale.

  Identity PSKs are unique pre-shared keys created for individuals or groups of users on the same SSID.

  No complex configuration required for clients. The same simplicity of PSK, making it ideal for IoT, BYOD, and guest deployments.

  Supported on most devices, where 802.1X may not, enabling stronger security for IoT.

  Easily revoke access, for a single device or individual, without affecting everyone else.

  Thousands of keys can easily be managed and distributed via the AAA server.

• Question 366:

  What is the recommended minimum SNR for voice applications on wireless networks?

  A. 10
  B. 15
  C. 20
  D. 25
  D. 25

  ---

  Explanation

  Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications.

• Question 367:

  What is the intent API in Cisco Catalyst Center (formerly DNA Center)?

  A. northbound consumer-facing RESTful API, which enables network discovery and configuration management
  B. southbound consumer-facing RESTful API. which enables network discovery and configuration management
  C. interface between the controller and the network devices, which enables network discovery and configuration management
  D. westbound interface, which allows the exchange of data such as ITSM. IPAM, and reporting information
  A. northbound consumer-facing RESTful API, which enables network discovery and configuration management

• Question 368:

  

  Refer to the exhibit. What is the result of the configuration?

  A. It enables NTP in client mode
  B. It allows interface g0/1 to send and receive NTP broadcast packets
  C. It allows interface g0/1 to send NTP broadcast packets.
  D. It allows interface g0/1 to receive NTP broadcast packets.
  C. It allows interface g0/1 to send NTP broadcast packets.

• Question 369:

  Which JSON script is properly formatted?

  

  A. Option A

  D. Option D
  C. Option C

• Question 370:

  Refer to the exhibit.

  

  Which IPv6 OSPF network type is applied to interface Fa0/0 of R2 by default?

  A. multipoint
  B. broadcast
  C. Ethernet
  D. point-to-point
  B. broadcast

  ---

  Explanation

  The Broadcast network type is the default for an OSPF enabled ethernet interface (while Point-to- Point is the default OSPF network type for Serial interface with HDLC and PPP encapsulation). Reference: https:// www.oreilly.com/library/view/ cisco-ios-cookbook/0596527225/ch08s15.html
