With Cisco ASA active/standby failover, what is needed to enable subsecond failover?

The default partitioner assigns key-values pairs to reduces based on an internal random number generator. ✘ The default partitioner implements a round-robin strategy, shuffling the key-value pairs to each reducer inturn. This ensures an event partition of the key space. ✘ The default partitioner computers the hash of the key. Hash values between specific ranges are associatedwith different buckets, and each bucket is assigned to a specific reducer. ✘ The default partitioner computers the hash of the key and divides that valule modulo the number ofreducers. The result determines the reducer assigned to process the key-value pair. ✔ The default partitioner computers the hash of the value and takes the mod of that value with the number ofreducers. The result determines the reducer assigned to process the key-value pair. ✔

Which option can cause the interactive setup script not to work on a Cisco ASA 5520 appliance running software version 8.4.1?

Sequences of MapReduce and Pig. These sequences can be combined with other actions including forks,
decision points, and path joins. ✘ Sequences of MapReduce job only; on Pig on Hive tasks or jobs. These MapReduce sequences can becombined with forks and path joins. ✘ Sequences of MapReduce and Pig jobs. These are limited to linear sequences of actions with exceptionhandlers but no forks. ✘ Iterntive repetition of MapReduce jobs until a desired answer or state is reached. ✔

Which statement about the Cisco ASA 5585-X appliance is true?

It accepts a single key-value pair as input and emits a single key and list of corresponding values as output. ✘ It accepts a single key-value pairs as input and can emit only one key-value pair as output. ✘ It accepts a list key-value pairs as input and can emit only one key-value pair as output. ✘ It accepts a single key-value pairs as input and can emit any number of key-value pair as output, includingzero. ✔

10.

Which logging mechanism is configured using MPF and allows high-volume traffic-related events to be exported from the Cisco ASA appliance in a more efficient and scalable manner compared to classic syslog logging?

When the types of the reduce operation s input key and input value match the types of the reducer s output
key and output value and when the reduce operation is both communicative and associative. ✘ When the signature of the reduce method matches the signature of the combine method. ✘ Always. Code can be reused in Java since it is a polymorphic object-oriented programming language. ✘ Always. The point of a combiner is to serve as a mini-reducer directly after the map phase to increaseperformance. ✔ Never. Combiners and reducers must be implemented separately because they serve different purposes. ✔
