CompTIA Updated SY0-701 Exam Questions and Answers by alaya

Centralized authentication (such as Active Directory or LDAP) combined with proper password policies helps prevent the reuse of the same local credentials across multiple systems, reducing the risk of lateral movement during attacks like credential reuse or pass-the-hash.

Aload balancerdistributes incoming traffic evenly across multiple servers to prevent any single server from becoming overloaded. This ensureshigh availability, scalability, and optimal performanceof the company ' s website.

Server multiprocessing (A)refers to the use of multiple processors within a single server but does not distribute traffic across multiple servers.

A warm site (B)is a disaster recovery strategy, not a method for balancing real-time traffic.

A proxy server (D)acts as an intermediary between users and web services but does not distribute server load.

Using aload balancerallows forefficient traffic management and prevents server overload.

Full disk encryption (FDE) is a technique that encrypts all the data on a hard drive, including the operating system, applications, and files. FDE protects the data from unauthorized access in case the laptop is lost, stolen, or disposed of without proper sanitization. FDE requires the user to enter a password, a PIN, a smart card, or a biometric factor to unlock the drive and boot the system. FDE can be implemented by using software solutions, such as BitLocker, FileVault, or VeraCrypt, or by using hardware solutions, such as self-encrypting drives (SEDs) or TrustedPlatform Modules (TPMs). FDE is a recommended encryption technique for laptops and other mobile devices that store sensitive data.

Partition encryption is a technique that encrypts only a specific partition or volume on a hard drive, leaving the rest of the drive unencrypted. Partition encryption is less secure than FDE, as it does not protect the entire drive and may leave traces of data on unencrypted areas. Partition encryption is also less convenient than FDE, as it requires the user to mount and unmount the encrypted partition manually.

Asymmetric encryption is a technique that uses a pair of keys, one public and one private, to encrypt and decrypt data. Asymmetric encryption is mainly used for securing communication, such as email, web, or VPN, rather than for encrypting data at rest. Asymmetric encryption is also slower and more computationally intensive than symmetric encryption, which is the type of encryption used by FDE and partition encryption.

Database encryption is a technique that encrypts data stored in a database, such as tables, columns, rows, or cells. Database encryption can be done at the application level, the database level, or the file system level. Database encryption is useful for protecting data from unauthorized access by database administrators, hackers, or malware, but it does not protect the data from physical theft or loss of the device that hosts the database.
