NEW QUESTION: 1
What is the minimum number of Data Movers needed to configure Data Mover for high availability?
A. 0
B. 1
C. 2
D. 3
Answer: B

NEW QUESTION: 2
CORRECT TEXT
Problem Scenario 49 : You have been given below code snippet (do a sum of values by key}, with intermediate output.
val keysWithValuesList = Array("foo=A", "foo=A", "foo=A", "foo=A", "foo=B", "bar=C",
"bar=D", "bar=D")
val data = sc.parallelize(keysWithValuesl_ist}
//Create key value pairs
val kv = data.map(_.split("=")).map(v => (v(0), v(l))).cache()
val initialCount = 0;
val countByKey = kv.aggregateByKey(initialCount)(addToCounts, sumPartitionCounts)
Now define two functions (addToCounts, sumPartitionCounts) such, which will produce following results.
Output 1
countByKey.collect
res3: Array[(String, Int)] = Array((foo,5), (bar,3))
import scala.collection._
val initialSet = scala.collection.mutable.HashSet.empty[String]
val uniqueByKey = kv.aggregateByKey(initialSet)(addToSet, mergePartitionSets)
Now define two functions (addToSet, mergePartitionSets) such, which will produce following results.
Output 2:
uniqueByKey.collect
res4: Array[(String, scala.collection.mutable.HashSet[String])] = Array((foo,Set(B, A}},
(bar,Set(C, D}}}
Answer:
Explanation:
See the explanation for Step by Step Solution and configuration.
Explanation:
Solution :
val addToCounts = (n: Int, v: String) => n + 1
val sumPartitionCounts = (p1: Int, p2: Int} => p1 + p2
val addToSet = (s: mutable.HashSet[String], v: String) => s += v
val mergePartitionSets = (p1: mutable.HashSet[String], p2: mutable.HashSet[String]) => p1
+ += p2

NEW QUESTION: 3
You need to upgrade the SSASCluster.
Which three actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)

Answer:
Explanation:

Explanation
Box 1:

Box 2:

Box 3:

Note:
* From scenario:
/ The current SQL Server environment consists of a single instance failover cluster of SQL Server 2008 R2 Analysis Services (SSAS). The virtual server name of the cluster is SSASCluster. The cluster includes two nodes: Node1 and Node2. Node1 is currently the active node. In anticipation of the upgrade, the prerequisites and shared components have been upgraded on both nodes of the cluster, and each node was rebooted during a weekly maintenance window.
The upgrade must minimize user intervention and administrative effort. So we'll upgrade using the scripted method rather than the GUI method.
* (box 1)
/ SQL Server Setup provides the ability to generate a configuration file based upon the system default and run-time inputs. You can use the configuration file to deploy SQL Server throughout the enterprise with the same configuration. You can also standardize manual installations throughout the enterprise, by creating a batch file that launches Setup.exe.
/ How to generate a configuration file
Insert the SQL Server installation media. From the root folder, double-click Setup.exe. To install from a network share, locate the root folder on the share, and then double-click Setup.exe.
Follow the wizard through to the Ready to Install page. The path to the configuration file is specified in the Ready to Install page in the configuration file path section. For more information about how to install SQL Server, see Install SQL Server 2012 from the Installation Wizard (Setup).
Cancel the setup without actually completing the installation, to generate the INI file.
* (box 2) First upgrade the passive node node2.
To be able to use the configuration file we use the command prompt. After the upgrade, the cluster will fail over to the upgraded node.
*( Box 3) upgrade Node1 (which is now the passive node)
* You can upgrade a SQL Server failover cluster to a SQL Server 2008 failover cluster by using the SQL Server Installation Wizard or a command prompt. One of the main features of SQL Server 2008 failover clustering is minimal downtime for rolling upgrades and updates.
* To control the failover behavior of cluster nodes during the upgrade process, run the upgrade operation at the command prompt and use the /FAILOVERCLUSTERROLLOWNERSHIP parameter.
* To upgrade a SQL Server failover cluster to SQL Server 2008 R2, you must run the Setup on one failover cluster node at a time, starting with the passive nodes. Setup determines when to fail over to the upgraded node, depending on the total number of nodes in the failover cluster instance, and the number of nodes that have already been upgraded. When half of the nodes or more have already been upgraded, Setup by default will cause a failover to an upgraded node.
To control the failover behavior of cluster nodes during the upgrade process, run the upgrade operation at the command prompt and use the /FAILOVERCLUSTERROLLOWNERSHIP parameter to control the failover behavior before the upgrade operation takes the node offline. Use of this parameter is as follows:
/FAILOVERCLUSTERROLLOWNERSHIP=0 will not roll cluster ownership (move group) to upgraded nodes, and does not add this node to the list of possible owners of the SQL Server cluster at the end of upgrade.
/FAILOVERCLUSTERROLLOWNERSHIP=1 will roll cluster ownership (move group) to upgraded nodes, and will add this node to the list of possible owners of the SQL Server cluster at the end of upgrade.
/FAILOVERCLUSTERROLLOWNERSHIP=2 is the default setting. It will be used if this parameter is not specified. This setting indicates that SQL Server Setup will manage cluster ownership (move group) as needed.

NEW QUESTION: 4
He was_______in his vindictiveness, often feigning a disarming camaraderie while his opportunity for revenge.
A. devious.. awaiting
B. harmless.. preparing
C. resolute.. forgetting
D. impulsive.. gauging
E. brazen.. dreading
Answer: A
Explanation:
Explanation/Reference:
Explanation:
The parson described is said to the 'often a disarming camaraderie', meaning that his friendship was not genuine, but was a pretended one. the use of the word 'revenge' indicates that the person In whom he was pretending friendship was one who had harmed him earlier So, the sentence must mean that the person described in the sentence was intent upon taking revenge for this earlier harm. I must therefore be looking for an opportunity to lake revenge, even while pretending friendship. So, among Ire choices for the second missing word, only 'preparing' and 'awaiting' are appropriate. Such a clever person will obviously not be
'harmless in his vindictiveness. So. B . is not a suitable choice for the first missing word "Devious'. meaning
'cunning is what describes such a person perfectly, and fits in well in the first blank. So. E is the answer
