When object-oriented design is used, which action represents the best practice to modify data contained within an object?

• A.Use the provided "setter" methods to modify data inside an object.
• B.When possible, directly modify data to reduce overhead and improve application performance.
• C.Use object update queues.
• D.Do not modify the object directly. Instead, create a copy and modify data in the duplicated object.
• E.After objects are instantiated, they should not be modified because it may result in redundant objects in the memory space.

Which command is used to find the string "connected" in file "controller.log", assuming a Linux environment?

• A.grep "connected" controller.log
• B.search "connected" controller.log
• C.find controller.log "connected"
• D.locate "connected" controller.log

Assume your application called StartMyRoute is running on your router and has established a route.
Which statement describes how you can quickly determine whether the route was established?

• A.Look at the routing tables and note the application route by its code and next-hop gateway.
• B.Use the onePK CLI command #show onep statistics StartMyRoute to verify application statistics and that Bytes In and Bytes Out are incrementing.
• C.Ping across the network to see if you can reach a far-end host.
• D.Use onePK CLI debug commands to determine that the route of the application has been established.
• E.Use onePK CLI commands to determine if the application is running and that the route is established.

Which statement about associative arrays is true?

• A.Associative arrays can be indexed only by strings.
• B.Associative arrays can be implemented by hashing the key and using the hash for lookup.
• C.Associative arrays can be indexed only by integers.
• D.Associative arrays can access an arbitrary element in constant time.

A packet-encapsulated NVGRE is sent from one virtual switch to another virtual switch. When the DF bit of the outer IP header is set, the packet is dropped by the switch-X between them because the frame size is bigger than the MTU size of interfaces of the switch-X.
Which action is the correct one to fix this problem without impacting performance?

• A.Expand the MTU configuration of the switch-X to accept the biggest NVGRE frames.
• B.Change the configuration of virtual switches not to send bigger NVGRE frames than the switch-X interface MTU.
• C.Change the configuration of virtual switches not to set the DF bit.
• D.Change the configuration of virtual switches to use VXLAN instead of NVGRE.
