• Question 56:

  A customer writes an internal application that does not run properly and crashes. Which component of the HP VAN SDN Controller framework offers protection so that other applications continue to function?

  A. OSGi

  B. Zookeeper

  C. Cassandra

  D. Keystone

  Correct Answer: A

  Note:

  The OSGi specification describes a modular system and a service platform for the Java programming

  language that implements a complete and dynamic component model, something that does not exist in

  standalone Java/VM environments. Applications or components, coming in the form of bundles for

  deployment, can be remotely installed, started, stopped, updated, and uninstalled without requiring a

  reboot; management of Java packages/classes is specified in great detail. Application life cycle

  management is implemented via APIs that allow for remote downloading of management policies. The

  service registry allows bundles to detect the addition of new services, or the removal of services, and adapt

  accordingly.

  Incorrect:

  Not Zookeeper: ZooKeeper is a centralized service for maintaining configuration information, naming,

  providing distributed synchronization, and providing group services. Not Cassandra: Apache Cassandra is

  an open source distributed database management system designed to handle large amounts of data

  across many commodity servers, providing high availability with no single point of failure.

  Not Keystone: The SDN controller uses Openstack Keystone as an identity management for managing

  users, generating tokens, as well as token validation.

• Question 57:

  A network administrator wants to back up the HP VAN SDN Controller. Which files will need to be downloaded and kept together? (Select two.)

  A. sdn_controller_backcup_.rar

  B. sdn_concroller_backup_.rar.MD5

  C. sdn_cont;roller_backcup_.zip

  D. sdn_controller_backcup_.zip.MD5

  E. sdn controller backup .tgz

  Correct Answer: CD

  Download a Backup From the Controller to Another Location Both the .zip file and the .MD5 (checksum) file (zip.MD5) should be downloaded to the same, secure location. Choose the correct name now; you cannot rename the files later Details (check the file extensions):

  1.

  Download the Backup .zip File: curl --noproxy --header "X-Auth-Token:" --fail -ksSfL --request GET --url "https://:8443/sdn/v2.0/systems//backup?csum=false" > .zip

  2.

  Download the backup .MD5 (Checksum) File curl --noproxy --header "X-Auth-Token:" --fail -ksSfL --request GET --url "https://:8443/sdn/v2.0/systems//backup?csum=true" > .zip.MD5

• Question 59:

  How is a leader elected in an HP VAN SDN Controller team by default?

  A. by the lowest IP address value

  B. by the lowest priority value

  C. by the highest priority value

  D. by the highest IP address value

  Correct Answer: C

  Once a team is configured, the configuration and monitoring of team members and their associated OpenFlow switches is performed by the team manager. If the team manager goes down, the controller with the next highest priority in the team configuration becomes the team manager. Note: Team Management Each controller belonging to a team is a team member. To centralize team management and control, one controller is designated as the team manager. Teaming is configured on one controller and is automatically propagated to the other controllers in the team, regardless of which controller becomes the team manager.
