질문 # 35
A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance. What should the architect do to avoid any costly service disruptions and ensure data durability?
- A. Copy the Object Storage bucket to a block volume.
- B. Create a replication policy to send data to a different bucket in another OCI region.
- C. Create a new Object Storage bucket in another region and configure recycle policy to move data every
5 days. - D. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
정답:B
설명:
For an online trading platform requiring high availability and fault tolerance, it's critical to ensure data durability and avoid any costly service disruptions. In Oracle Cloud Infrastructure (OCI), Object Storage is often used to store critical data, such as transaction logs or user data, due to its scalability, durability, and reliability.
Option Bis the most suitable approach for ensuring data durability and availability across regions. Here's why:
* Cross-Region Replication (CRR):OCI offers a feature called Cross-Region Replication for Object Storage. This feature allows you to automatically and asynchronously replicate objects in a bucket from one OCI region to another. This setup ensures that even if one region experiences a failure, the data is still available in another region, thereby meeting the requirements for high availability and fault tolerance.
* Data Durability:By replicating data to another region, you protect against regional outages. OCI guarantees 99.95% availability for replicated data, which is critical for a financial firm's trading platform where data consistency and durability are paramount.
* Disaster Recovery:With data replicated in another region, the trading platform can quickly switch to using the data in the secondary region in case of a disaster in the primary region. This setup significantly reduces recovery time objectives (RTO) and ensures business continuity.
References:
* Oracle Cloud Infrastructure Documentation:Cross-Region Replication for Object Storage
* Oracle Whitepaper:High Availability and Disaster Recovery in Oracle Cloud Infrastructure Explanation of Incorrect Options:
* Option A:Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the faulttolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery.
* Option C:While lifecycle policies are useful for moving less frequently accessed data to a more cost- effective storage tier (e.g., from Standard to Archive), they do not address cross-region redundancy or real-time availability, which are critical for this use case.
* Option D:Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross-region availability as replication policies.
Thus,Option Bis the correct and most efficient method for ensuring high availability and fault tolerance in this scenario.
질문 # 36
Which THREE protocols are supported by the Oracle Cloud Infrastructure (OCI) private Network Load Balancers?
- A. UDP
- B. HTTP
- C. BGP
- D. ICMP
- E. iSCSI
- F. TCP
정답:A,B,F
질문 # 37
Which statement accurately describes ephemeral principals?
- A. Ephemeral principals are temporary credentials granted to resources.
- B. Ephemeral principals represent long-lived service accounts.
- C. Ephemeral principals are another term for dynamic groups.
- D. Ephemeral principals are user accounts with limited lifespans.
정답:A
질문 # 38
You want to protect your VM instance from low-level threats, such as rootkits and bootkits. What should you do?
- A. Create a burstable instance.
- B. Create a shielded instance.
- C. Use Vulnerability Scanning Service.
- D. Use in-transit encryption.
정답:B
질문 # 39
Why was SSH still possible after port 22 was removed from the Security Lists?
- A. The VCN where that compute instance resides still has a route rule.
- B. The VCN where that compute instance resides still has an Internet Gateway.
- C. The VNIC of that compute instance is attached to a Cluster Network.
- D. The VNIC of that compute instance is attached to a Network Security Group (NSG).
정답:D
설명:
Even after removing port 22 from the Security Lists, SSH was still possible because the Virtual Network Interface Card (VNIC) of the compute instance is attached to aNetwork Security Group (NSG).
* NSGs:NSGs provide a more flexible and granular way to manage security rules compared to Security Lists. They allow you to apply security rules directly to VNICs associated with resources such as compute instances. If an NSG allows traffic on port 22, SSH will still be possible, regardless of the Security List settings.
