• Question 165:

  Refer to the exhibit.

  

  A developer runs the docker service scale command to increase the number of replicas for the cisco_devnet service. The swarm cluster is using a private IP address subnet. The service has these design requirements:

  1. It must be hosted behind a virtual IP address that is reachable from the Internet.

  2. For security reasons, the Docker swarm cluster subnet must not be reachable from the Internet.

  Which design approach is used to fulfill the requirements?

  A. Create an overlay network by using a globally roulable subnet and enable a routing mesh within the swarm cluster.
  B. Create a bridge network by using a globally routable subnet and enable a routing mesh within the swarm cluster.
  C. Configure an external load balancer to route requests to the swarm service by using VPN.
  D. Configure an external load balancer to route requests to the swarm service by using NAT.
  D. Configure an external load balancer to route requests to the swarm service by using NAT.

  ---

  Explanation

  The design approach that fulfills the requirements is to configure an external load balancer to route requests to the swarm service by using NAT. This will allow the service to be hosted behind a virtual IP address that is reachable from the Internet, while keeping the Docker swarm cluster subnet unreachable from the Internet.

• Question 166:

  DRAG DROP

  Refer to the exhibit.

  

  Drag and drop the code snippets from the bottom onto the blanks in the Python script to retrieve wireless client health data by using the Cisco Catalyst Center (formerly DNA Center) API. Not all options are used.

  A. Use tokens after the identity of a client has been established.
  B. Use the same operating system throughout the infrastructure.
  C. Use encryption and signatures to secure data.
  D. Use basic auth credentials over all internal API interactions.
  E. Use cloud hosting services to manage security configuration.
  A. Use tokens after the identity of a client has been established.
  C. Use encryption and signatures to secure data.

  B. SSLProxyCACertificatePath - "/usr/local/apache2/conf/ssl/ca_bundle.crt"
  C. SSLCertiflcateChainFile - "/usr/local/apache2/conf/ssl/ca_bundle.crt"
  D. SSLCipherSuite - "/usr/local/apache2/conf/ssl/ca_bundle.crt"
  C. SSLCertiflcateChainFile - "/usr/local/apache2/conf/ssl/ca_bundle.crt"

• Question 170:

  An engineer is designing an application to interact with Cisco Catalyst Center (formerly DNA Center). The application must use multiple components that serve unique functions that range from device data collection, analysis, and monitoring to a custom dashboard. It must meet these development requirements:

  1. Application components are easy to replace.

  2. Application components are easy to re-use.

  3. It can scale up at short notice.

  4. It allows work to be done on specific components independently.

  Which design practice must the engineer apply?
