Question 6:

Refer to the exhibit.

350-601 dumps practice questions 6

What happens to the broadcast traffic when it reaches aggregation switches?

A. Agg-2 switch receives broadcast packets and stops forwarding to the peer link on the Agg-1 switch.

B. Agg-1 switch prevents broadcast packets received on the vPC peer link from exiting the switch on ports Eth2/4 and Eth2/5.

C. Agg-1 and Agg-2 switches receive broadcast packets and do not forward them to the peer link or the port channel.

D. Only the Agg-1 switch receives broadcast packets and does not forward them to the peer link on the Agg-2 switch.

Correct Answer: B

Duplicate Frames Prevention in vPC One of the most important forwarding rules for vPC is that a frame that enters the vPC peer switch from the peer link cannot exit the switch from a vPC member port. Figure shows switches 3 and 4 connected to 5k01 and 5k02 with vPCs Po51 and Po52. If one of the hosts connected to switch 4 sends either an unknown unicast or a broadcast, this traffic may get hashed to port eth2/2 on PortChannel 52. 5k02 receives the broadcast and needs to forward it to the peer link for the potential orphan ports on 5k01 to receive it.

Upon receiving the broadcast, 5k01 detects that this frame is coming from the vPC peer link. Therefore, it does not forward it to port 2/9 or 2/10; if it did, a duplicate frame on switch 3 or 4, respectively, would be created. If a host on switch 4 sends a broadcast, 5k02 will correctly forward it to Po51 on port 2/9 and place it on the peer link.

5k01 will prevent this broadcast frame from exiting onto port 2/9 or 2/10 because this frame entered 5k01 from a vPC peer link. Should eth2/2 on switch 3 go down, port 2/9 on 5k01 would become an orphan port and as a result will receive traffic that traverses the peer link.

NEW Q1

You have a Power BI dataset that contains a table named Temperature Readings. Temperature Readings contain the columns shown in the following table.

The table has 12 million rows. All the columns are needed for analysis. You need to optimize the dataset to decrease the model size. The solution must not affect the precision of the data. What should you do?

A. Split the DateTime column into separate date and time columns.
B. Disable the Power Query load.
C. Round the Longitude column to two decimal places.
D. Change the data type of the TempCelsius column to Integer

Correct Answer: B

Disable Power Query load. Power Query queries that are intended to support data integration with other queries should not be loaded into the model. To avoid loading the query to the model, take care to ensure that you disable query load in these instances.

Reference:
https://docs.microsoft.com/en-us/power-bi/guidance/import-modeling-data-reduction#disable-power-query-query-load

NEW Q2

NEW Q3

You have a collection of reports for the HR department of your company. The datasets use row-level security (RLS). The company has multiple sales regions that each have an HR manager. You need to ensure that the HR managers can interact with the data from their region only. The HR managers must be prevented from changing the layout of the reports. How should you provide access to the reports for the HR managers?

A. Create a new workspace, copy the datasets and reports, and add the HR managers as members of the workspace.
B. Publish the reports to a different workspace other than the one hosting the datasets.
C. Publish the reports in an app and grant the HR managers access permission.
D. Add the HR managers as members of the existing workspace that hosts the reports and the datasets.

Correct Answer: C

Note: Row-level security (RLS) with Power BI can be used to restrict data access for given users. Filters restrict data access at the row level, and you can define filters within roles. In the Power BI service, members of a workspace have access to datasets in the workspace.
RLS doesn’t restrict this data access.

Reference:
https://docs.microsoft.com/en-us/power-bi/admin/service-admin-rls

QUESTION 17
View Exhibit1 to examine the description of the CUSTOMERS table.

You observed that optimizer selectivity is not accurate when the CUST_STATE_PROVINCE and COUNTRY_ID columns are used together in the WHERE clause of a query. View Exhibit2 to examine the query execution plan and the commands executed to gather the statistics.

The optimizer predicts that 20 rows will be processed rather than the 3,341 rows, which is the actual number of rows returned from the table. What can you do to make the optimizer detect the actual number of rows?
A. Set the STATISTICS_LEVEL parameter to ALL.
B. Set the OPTIMIZER_USE_PENDING_STATISTICS parameter to FALSE.
C. Create extended statistics for the CUST_STATE_PROVINCE and COUNTRY_ID columns.
D. Increase the STALE_PERCENT value for the CUSTOMERS table by using the DBMS_STATS.SET_TABLE_PREFS procedure. Correct Answer: C QUESTION 18
View Exhibit1 to examine the description of the CUSTOMERS table.

The CUSTOMERS table has been updated heavily today. In a frequently used SQL statement, you notice that estimated rows and the actual number of rows
fetched differ greatly. The COUNTRY_ID column has an index.
View Exhibit2 and examine the query execution plan.
What would you recommend to improve the optimizer’s estimation?
A. setting the STATISTICS_LEVEL parameter to ALL
B. setting the OPTIMIZER_USE_PENDING_STATISTICS parameter to FALSE
C. creating extended statistics for the CUST_LAST_NAME, CUST_ID, and CUST_TOTAL columns
D. updating the statistics for the CUSTOMERS table by using the DBMS_STATS.GATHER_TABLE_STATS procedure Correct Answer: D QUESTION 19
You are working on a decision support system (DSS). The index is available on the COUNTRY_ID column of the CUSTOMERS table.View the Exhibit and examine the parameter settings and the query execution plan.

Why is the query using a full table scan instead of an index scan?
A. because the histogram statistics for the COUNTRY_ID column are not updated
B. because the index statistics for the index on the COUNTRY_ID column are not current
C. because the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a higher value
D. because the optimizer predicts that most of the blocks in the table are accessed. Therefore, it uses a full table scan, even though indexes are available.

Correct Answer: D QUESTION 20
View Exhibit1 and examine the indexes on the CUSTOMERS table.

The statistics for the CUSTOMERS table have been updated recently by using the following command:
SQL> EXEC
DBMS_STATS.GATHER_TABLE_STATS(‘SH’,’CUSTOMERS’,method_opt=>’FOR ALL INDEXED COLUMNS SIZE AUTO’);
View Exhibit2 to examine a query plan. Even though the index is present on the COUNTRY_ID and CUST_GENDER columns, the query uses a full table scan.
What could be the reason?
A. because the histogram statistics for the COUNTRY_ID column are not updated
B. because the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a high value
C. because the optimizer calculates the cost of accessing blocks by using a full table scan to be less as compared to index scans, even though indexes are available
D. because indexes on CUST_GENDER and COUNTRY_ID columns are of different types, the index on the CUST_GENDER column is bitmap index, and on COUNTRY_ID columns is btree index.

Correct Answer: C
QUESTION 21
You are working on an online transaction processing (OLTP) system. The CUST table in the SH schema was populated by direct load and after that it has gone through a lot of updates and deletions. The statistics for the CUST and SALES tables were updated recently.View the Exhibit and examine the query plan.The query is performing a lot of I/O for a query that fetches only 168 rows. To investigate further, you queried the ALL_TABLES view to find out PCTUSED, PCTFREE, and the number of rows in the CUST table, as given below: SQL> SELECT table_name ,blocks, pct_used, pct_free, num_rows 2 FROM all_tables 3* WHERE table_name = ‘CUST’; TABLE_NAME BLOCKS PCT_USED PCT_FREE NUM_ROWS ———- ———- ———- ———- ———- CUST 13768 80 111060 What would you recommend to reduce the I/O?

A. reorganizing the table to use fewer blocks

A new plan is generated against the second query shown in the Exhibit as Plan-2. When explaining the plan for the second query, you observe that the optimizer uses the first plan instead of the second. The following parameters are set for the user session: OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES=TRUE OPTIMIZER_USE_SQL_PLAN_BASELINES=TRUE SQLTUNE_CATEGORY=DEFAULT Why does the optimizer not use the second plan?

A. because the second plan is not verified
B. because the second plan is not part of the SQL plan baseline
C. because the SQLTUNE_CATEGORY parameter is set to DEFAULT
D. because the explain plan option in the user session does not allow the new plan because SQLTUNE_CATEGORY parameter is set to DEFAULT

Correct Answer: A
QUESTION 40

QUESTION 44
Your company wants to migrate a single instance Oracle 11g Release 1 database to a RAC environment. The database supports middle-tier applications using
connection pooling for connecting to database.
Being a part of the performance management team, you want to test the performance of the SQL statements and the peak workload of the applications in the new
environment before upgrading the production system.
Given below are some of the steps in random order to accomplish the task:
1) Capture the real workload on the existing system.
2) Create a SQL Tuning Set (STS) for the statements executed by the application.
3) Transport STS on the test environment and use SQL Tuning Advisor to compare the before and after performance.
4) Replay the workload on the test environment.
5) Analyze the divergence after replay.
6) Use Automatic Workload Repository (AWR) to capture the information for top SQL on the existing system.
7) Transport STS on the test environment and use SQL Performance Analyzer to compare the before and after performance.
Identify the correct steps required to perform the test.

A. 2 and 3 only
