                                        1. It forces administrators to restart their web browsers after every page click.<\/span><\/li>\n
                                        2. It minimizes security risks by replacing older encryption keys with new ones, ensuring that compromised keys have a limited validity window.<\/span><\/li>\n
                                        3. It increases physical network switch port forwarding speeds.<\/span><\/li>\n
                                        4. It compresses virtual disk files to save datastore storage space.<\/span><\/li>\n<\/ol>\n

                                          Correct Answer:<\/b> 2<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          Periodic key rotation is a core security best practice for vSphere VM Encryption. By regularly retiring old keys and generating new cryptographic keys via integrated Key Management Services (KMS), organizations limit the exposure window if a key is ever compromised, protecting sensitive encrypted virtual machine data against unauthorized decryption over time.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
