A user has requested a field that counts the number of child records associated with a custom object. These custom objects have a lookup relationship between each other, which feature would best accomplish this requirement?
A. Apex Trigger
B. Roll-Up summary field
C. Lightning Process Builder
D. Visual Flow
Answer:
A. Apex Trigger
Explanation:
Apex Trigger: A trigger that gets executed before and after a record is Inserted/Updated/Deleted from the force.com database.
Syntax:
Trigger <trigger name> on <Object name> (trigger Events)
{
// your Logic here
}
Usually we use triggers when we have to perform such operations that are based on some specific conditions to modify related records. with Apex you can do SOQL and DML operations including;
Insert
Update
Delete
Merge
Upsert
Undelete
The feature that would best accomplish the requirement of counting the number of child records associated with a custom object through a lookup relationship is: B. Roll-Up summary field
Roll-Up summary fields allow you to calculate values from related records, such as counting the number of child records. It automatically updates based on changes to the child records, making it an ideal choice for this requirement.
A roll-up summary field would be the best choice for this requirement. Roll-up summary fields automatically calculate values from related records and can perform operations like counting the number of child records associated with a parent record.
To implement this, you would create a roll-up summary field on the parent custom object, choosing the appropriate relationship field and specifying the aggregation function as "Count." This field will then display the count of related child records, providing the user with the desired information without the need for manual calculations or complex logic.
To assist with controlling orphaned and dormant accounts, what can be used to indicate when an account is no longer active?
Answer:
Account Expiration is used
Explanation:
Orphaned account is linked to an inactive employee. This means that even after an employee has left an organization, this account remains active.
A dormant account has not been accessed and had no activity for a lengthy period of time.
These type of accounts are a security vulnerability. For example an employee who has left the company in some unpleasant circumstances can steal confidential information using his account. To handle the dormant and orphaned accounts there should be a process that disables the account for employees who have left or dismissed and employee's access to the account should be ended right away. Moreover monitoring the accounts helps to restrain using other accounts. So the security risk can be reduced using account expiration. This involves the use of automatic expiration date for the user accounts or to set an account to expire once the its password is expired for a certain number of days. So the account will be automatically disabled when the contract period of the employee is ends.
If Windows does not automatically detect a newly added device, to get the device recognized and the drivers installed, you should _________.
Answer:
Update the device driver
Explanation:
Devices drivers are softwares used to link a component of the computer to the operating system functionality.
It normally comes with the installed operating system, but most plug and play devices , come with a little built-in OS that runs once it is plugged in.
If a device is not recognized, update the driver software and restart the system.
To get Windows to recognize a newly added device, manually run the Add Hardware Wizard from the Control Panel, use Device Manager to install drivers, or download drivers from the manufacturer's website.
If Windows does not automatically detect a newly added device, to get the device recognized and the drivers installed, you should manually run the Add Hardware Wizard in Windows. Access the wizard from the Control Panel under Hardware and Sound, or search for it in the Start menu.
Follow the prompts to install the device drivers which can also be found through the Device Manager. It may be necessary to download and install drivers from the manufacturer's website if Windows does not have the appropriate drivers.
Which of the following is true regarding the use of instance variable j in class B1?
A) It is directly accessible only in B1
B) It is directly accessible only in B2
C) It is directly accessible only in B3
D) It is directly accessible in B1 and B2
E) It is directly accessible in B1, B2, and B3
Answer: A) It is directly accessible only in B1
Explanation: In the given chunk of code, Class B1 is a base class. Class B2 is derived class of class B1. Class B3 is derived class of B2. As you can see class B1 has two members or instance variables i and j. Instance variable cannot be directly accessible by both B2 and B3. If you see this statement of the given code private int j; the keyword private is used with the variable j. This keyword is called access specifier. Access specifiers specifies how the members of a class can be accessed. These members are attributes and methods of that class. Any member of a class that are declared private cannot be inherited by derived classes of that class. Additionally these private members cannot be accessed from within any method inside derived class. So j is directly accessible only in B1. You can access a private instance variable from within the same class or can access it through the methods of class.

which command should you enter to configure a single port to discard inferior bpdus 200-125?
Answer:
spanning-tree portfast bpduguard
Explanation:
spanning- tree protocol (STP) is a layer 2 protocol in the OSI model. It is automatically configured in a switch to prevent continual looping of BPDUs, to avoid traffic congestion. The fastport bpduguard is only applicable in non-trunking access in a switch. It is more secure to configure the fastport mode in switch port connected directly to a node, because there are still bpdus transfer in a switch to switch connection.
BPDUs Guard ensures that inferior bpdus are blocked, allowing STP to shut an access port in this regard.

Technician A says that the ECT and IAT sensors can be tested by using a digital multimeter or a scan tool. Technician B says that the ECT sensor is a high-authority sensor at engine start-up and is used for open-loop control, as well as idle speed. Who is right?Select one:a. Both technicians A and Bb. Neither technician A nor Bc. Technician A onlyd. Technician B only
Answer:
A) Both Techician A and B are correct
Explanation:
IAT refers to the Intake Air Temperature sensor while ECT refers to Electronically Controlled Transmission sensor. The IAT is a thermistor whose values changes based on the air temperature entering the engine, the ECT controls engine revolution. The statements in the questions by both technicians are correct
Final answer:
Both Technician A and B are correct. Technician A states that ECT and IAT sensors can be tested with a digital multimeter or scan tool, while Technician B underlines the importance of the ECT sensor during the engine start-up for open-loop control and idle speed regulation.
Explanation:
The correct answer is a. Both technicians A and B. Technician A is correct in saying that the Engine Coolant Temperature (ECT) and Intake Air Temperature (IAT) sensors can be tested using a digital multimeter or a scan tool. These tests can measure the electrical resistance of the sensors, which changes with temperature changes. Technician B is also correct, as the ECT sensor is indeed a high-authority sensor during engine startup. It significantly influences the engine's fuel management system by providing temperature data that the engine control unit (ECU) uses for open-loop control. This period of engine operation occurs before the oxygen sensors heat up and are able to provide feedback to the ECU. The ECT sensor also contributes to regulating the idle speed during a cold start, when the engine requires a higher idle speed to avoid stalling and to warm up efficiently.
A salesperson in your organization spends most of her time traveling between customer sites.After a customer visit, she must complete various managerial tasks, such as updating yourorganization's order database.Because she rarely comes back to your home office, she usually accesses the network from hernotebook computer using Wi-Fi access provided by hotels, restaurants, and airports.Many of these locations provide unencrypted public Wi-Fi access, and you are concerned thatsensitive data could be exposed. To remedy this situation, you decide to configure her notebookto use a VPN when accessing the home network over an open wireless connection.Which key steps should you take when implementing this configuration? (Select two.)a. Configure the VPN connection to use MS-CHAPv2.b. Configure the browser to send HTTPS requests through the VPN connection.c. Configure the VPN connection to use IPsec.d. Configure the browser to send HTTPS requests directly to the Wi-Fi network withoutgoing through the VPN connection.e. Configure the VPN connection to use PPTP.
Answer: b. configure the browser to send HTTPS requests through the VPN connection
e. configure the VPN connection to use PPTP
Explanation:
b. sending the HTTPS requests directly to the WiFi network will bypass the VPN which will make the sensitive data vulnerable, hence, defeating the reason for making use of the VPN.
e. the salesperson accesses the WiFi using her notebook computer, which is most likely going to be running on a windows operating system, OS. The VPN connection type for windows OS is usually PPTP (it will be provided in the subscription details by the VPN being used). However, Mac OS does not support the PPTP. In such cases, the VPN being used will also provide the information (usually IKEv2).
