You have mission critical application which requires to be globally available at all time. Which deployment strategy should you adopt? 6 | P a g e Created by ©EmilyCharlene 2025. All rights reserved. - Use multiple fault domain in any availability domain with multiple regions. - Use multiple fault domains in one regions - Use multiple fault domains in each availability domain in each region - Use multiple availability domains in one Region - ANSWER -Use multiple fault domain in any availability domain with multiple regions Explanation: Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region. fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains. According to standard security model which 2 are a customer's responsibilities in OCI? - Physical Security of OCI data center facilities - Object Storage Data Security - Virtual Machine Hypervisor 7 | P a g e Created by ©EmilyCharlene 2025. All rights reserved. - Customer Data - Local data persistence - ANSWER -Customer Data & Object Storage Data Security Which 3 services integrate with OCI Key Management? - File Storage - Auto Scaling - Identity and Access Management - Object Storage - Block Volume - Functions - ANSWER -- File Storage - Object Storage - Block Volume Explanation: DATA ENCRYPTIONProtect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management The Oracle Cloud Infrastructure Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption. By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key
