1. What should a system administrator use to disable access to a custom application for a group of users?A. ProfilesB. Sharing rulesC. Web tabsD. Page layouts
A system administrator can use profiles to disable access to a custom application for a group of users. Profiles are a collection of settings and permissions that determine what a user can access and perform within an organization's Salesforce instance.
By assigning a profile to a group of users, the system administrator can control their access to different objects, fields, tabs, and applications. To disable access to a custom application for a group of users, the system administrator can simply remove the custom application from the user's profile.
Sharing rules, web tabs, and page layouts are not the appropriate tools to disable access to a custom application for a group of users. Sharing rules are used to grant access to specific records based on criteria such as roles or territories. Web tabs allow users to access external web applications from within Salesforce, and page layouts determine the layout and organization of fields and related lists on a record detail page. Therefore, these tools are not designed to restrict access to a custom application.
In summary, a system administrator should use profiles to disable access to a custom application for a group of users. By removing the custom application from the user's profile, the system administrator can control their access to different Salesforce features and functionalities.

Explain what a scheduler does? What is compute-bound (memory) and I/O-bound? What difference does this make to the scheduler?
A scheduler is responsible for determining which tasks should be executed by the CPU and when.
A scheduler needs to consider whether a task is compute-bound (meaning it requires a lot of processing power) or I/O-bound (meaning it spends a lot of time waiting for input/output operations to complete).
This distinction is important because if the scheduler gives priority to compute-bound tasks, I/O-bound tasks may be starved of resources and their performance will suffer. Conversely, if the scheduler gives priority to I/O-bound tasks, compute-bound tasks may take longer to complete.
Therefore, a good scheduler will balance the CPU's workload to ensure that all tasks are given fair access to the CPU's resources, regardless of whether they are compute-bound or I/O-bound.

True or false? Perfect forward secrecy (PFS) ensures that a compromise of a server's private key will not also put copies of traffic sent to that server in the past at risk of decryption.
True, Perfect Forward Secrecy (PFS) ensures that a compromise of a server's private key will not also put copies of traffic sent to that server in the past at risk of decryption.
PFS is a cryptographic technique that uses temporary, ephemeral key pairs for each communication session, rather than relying on a single, long-term private key for the server. This means that even if the server's private key is compromised, the attacker would not be able to decrypt past communication sessions, as each session used a unique, temporary key pair.
In a PFS-enabled system, the following steps take place during the key exchange process:
1. The client and server generate their respective ephemeral public-private key pairs.
2. The client and server exchange their ephemeral public keys.
3. Both parties use their private keys and the received public keys to derive a shared secret key for the session.
4. The session keys are used to encrypt and decrypt the data transmitted during that specific session.
5. At the end of the session, the ephemeral keys are deleted, ensuring that the session keys cannot be recreated.
By following these steps, PFS provides an additional layer of security, protecting past communications from being decrypted even if the server's long-term private key is compromised.
