Port 443 is used for HTTPS, which is a secure version of HTTP that encrypts the data between the web server and the client. Port 3389 is used for RDP, which is a protocol that allows remote desktop connections to a server. These ports should be allowed for a secure web server that can be administered via RDP.

Scalability
Answers
Suggested answer: C

Explanation:

Overprovisioning is a situation where the allocated resources for a virtual machine exceed the available resources of the physical host. In this case, the storage allocated for Server 1 and Server 2 on VM01 is 8TB and 10TB respectively, which adds up to 18TB. However, the storage available on the VM01 host is only 16TB, which means there is a 2TB deficit. This can cause performance issues and errors for the virtual machines.

Explanation:

Scope-based authentication is a method of restricting access to resources based on the location, network, or device of the user. It can be used to prevent unauthorized access from outside the organization's network or from untrusted devices. In this case, the user can connect to the database server from the home office, which is likely within the scope of the authentication policy, but not from the hotel room, which is outside the scope.

Suggested answer: A

Explanation:

Application consistent backup is a method of backing up data that ensures the integrity and consistency of the application state. It involves notifying the application to flush its data from memory to disk and quiescing any write operations before taking a snapshot of the data. If the databases were not backed up to be application consistent, they might contain incomplete or corrupted data that cannot be restored properly.

Suggested answer: A

Explanation:

A warm site is a backup site that has some of the necessary hardware, software, and network resources to resume operations, but not all of them. A warm site requires some time and effort to become fully operational. A warm site is different from a cold site, which has minimal or no resources, and a hot site, which has all the resources and is ready to take over immediately.

Suggested answer: A

Explanation:

Drive encryption is a form of data-at-rest encryption that encrypts the entire hard drive or solid state drive. This means that all the data on the drive, including the operating system, applications, and files, are protected from unauthorized access. Drive encryption is usually implemented at the hardware or firmware level, and requires a password, PIN, or biometric authentication to unlock the drive. Drive encryption is the most comprehensive and secure way to achieve data-at-rest encryption, as it prevents anyone from accessing the data without the proper credentials, even if they physically remove the drive from the server.
