Which one of the following is used to obtain performance information about a Web Application?

  1. Performance Counters

  2. Data Performance Counters

  3. Web Performance Counters

  4. Data Readers

Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of performance monitoring in web applications.

Option A) Performance Counters - This option is correct because performance counters are a feature of the Windows operating system that allows you to monitor various aspects of system performance. Performance counters can be used to obtain performance information about a web application, such as CPU usage, memory usage, network traffic, and disk activity.

Option B) Data Performance Counters - This option is incorrect because there is no specific term called "Data Performance Counters." It is likely a combination of two different concepts - "data counters" and "performance counters."

Option C) Web Performance Counters - This option is incorrect because although "Web Performance Counters" sounds related to web applications, it is not a commonly used term or feature. Performance counters are more commonly used for monitoring system performance rather than specific web application performance.

Option D) Data Readers - This option is incorrect because "Data Readers" is a term typically used in database programming to read data from a database. It is not directly related to obtaining performance information about a web application.

The correct answer is A) Performance Counters. This option is correct because performance counters are commonly used to obtain performance information about a web application.

This is the most important measure in dealing with performance issues.

  1. CPU

  2. Availabilty

  3. Response Time

  4. Throughput

Correct Option: C

This phase of Oracle tuning is directed at looking for resource shortages in the db_block_buffers, shared_pool_size and sort_area_size.

  1. Instance Tuning

  2. Object Tuning

  3. SQL Tuning

  4. Space Management

Correct Option: A

This parameter lets you tune optimizer behavior for access path selection to be more or less index friendly, that is, to make the optimizer more or less prone to selecting an index access path over a full table scan. The default makes full table scan and index use equal.

  1. Optimizer Index Caching

  2. Optimizer Index Cost Adjustments

  3. Optimizer Mode

  4. Parallel Automatic Tuning

Correct Option: B

This RAID configuration stripes data across multiple volumes. One volume is devoted to "parity bits." The bits are used to reconstruct data should you lose a data volume.

  1. RAID 1

  2. RAID 0+1

  3. RAID 3

  4. RAID 5

Correct Option: C

This tool in Oracle10g defaults to a collection interval every 30 minutes and collects data that is the foundation for all of the other self-tuning features. It is very much like STATSPACK, especially the level-5 STATSPACK collection mechanism where top SQL is collected every hour, based on your rolling thresholds for high-use SQL.

  1. Automatic Maintenance Tasks(AMT)

  2. Automatic Workload Repository(AWR)

  3. Automatic Database Diagnostic Monitor(ADDM)

  4. Automatic Storage Management(ASM)

Correct Option: B

What is the full form of ISM?

  1. Internet Service Monitor

  2. Internet Service Monitors

  3. Internet Service Monitoring

  4. Internet Services Monitoring

Correct Option: B

Where does ISM store logs?

  1. /opt/Netcool/var/logs

  2. /opt/Netcool/ism/datalogs

  3. /opt/Netcool/log/ism

  4. /opt/Netcool/ism/log

Correct Option: C

ISM startup script resides in...

  1. /opt/Netcool/bin/ism

  2. /opt/Netcool/bin

  3. /opt/Netcool/ism/scripts

  4. /opt/Netcool/ism/bin

Correct Option: D

ISM can monitor RADIUS servers.

  1. True

  2. False

Correct Option: A
  1. 1 day

  2. 7 days

  3. 30 days

  4. 365 days

Correct Option: A

  4. Larry Wall

Correct Option: A

MRTG can monitor

  1. Router

  2. Firewall

  3. Switch

  4. All of them

Correct Option: D

AI Explanation

To answer this question, you need to understand what MRTG (Multi Router Traffic Grapher) is and what it can monitor.

MRTG is a free and open-source network monitoring tool that allows you to monitor and graph various parameters of network devices. It primarily monitors network traffic and bandwidth utilization.

Let's go through each option to understand which devices MRTG can monitor:

Option A) Router - MRTG can monitor routers. It can measure and graph the traffic and bandwidth utilization of routers, allowing you to monitor the performance and usage of your network.

Option B) Firewall - MRTG can also monitor firewalls. It can track and display the traffic passing through the firewall, helping you analyze the network traffic and identify any potential issues or bottlenecks.

Option C) Switch - MRTG can monitor switches as well. It can monitor the traffic flowing through the switch ports, providing you with insights into the switch's performance and the network's usage.

Option D) All of them - The correct answer is D. MRTG can monitor routers, firewalls, and switches. It is a versatile tool that can monitor various network devices and provide you with valuable information about their performance and usage.

In conclusion, MRTG can monitor routers, firewalls, and switches, making option D the correct answer.
