A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple continents. The average volume of data that the company collects from each site daily is 500 GB. Each site has a high-speed Internet connection.
The company wants to aggregate the data from all these global sites as quickly as possible in a single Amazon S3 bucket. The solution must minimize operational complexity.
Which solution meets these requirements?
A. Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket.
B. Upload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket. Then remove the data from the origin S3 bucket.
C. Schedule AWS Snowball Edge Storage Optimized device jobs daily to transfer data from each site to the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket.
D. Upload the data from each site to an Amazon EC2 instance in the closest Region. Store the data in an Amazon Elastic Block Store (Amazon EBS) volume. At regular intervals, take an EBS snapshot and copy it to the Region that contains the destination S3 bucket. Restore the EBS volume in that Region.

技巧:排除明顯錯(cuò)誤選項(xiàng),在沒(méi)有明顯錯(cuò)誤的選項(xiàng)中選擇最合理的選項(xiàng)。
某公司在多個(gè)大陸的城市收集溫度、濕度和大氣壓力數(shù)據(jù),并希望盡快將這些全球站點(diǎn)的數(shù)據(jù)匯總到一個(gè)Amazon S3存儲(chǔ)桶中的需求,同時(shí)要求盡可能簡(jiǎn)化操作復(fù)雜度,限制需要提出一個(gè)合理的解決方案
A. 正確。在目標(biāo)S3存儲(chǔ)桶上啟用S3傳輸加速。使用多部分上傳直接將站點(diǎn)數(shù)據(jù)上傳到目標(biāo)S3存儲(chǔ)桶。啟用S3傳輸加速,可以加快全球各地?cái)?shù)據(jù)上傳到S3存儲(chǔ)桶的速度。傳輸加速通過(guò)Amazon CloudFront網(wǎng)絡(luò)邊緣位置來(lái)接收數(shù)據(jù),然后利用Amazon S3的內(nèi)部網(wǎng)絡(luò)將數(shù)據(jù)高效地傳輸?shù)侥繕?biāo)存儲(chǔ)桶。此外,使用多部分上傳可以處理大文件,提高上傳效率和可靠性。這種方式簡(jiǎn)化了操作,因?yàn)樗袛?shù)據(jù)都直接上傳到目標(biāo)存儲(chǔ)桶,無(wú)需額外的復(fù)制或同步步驟。
B. 不正確。將每個(gè)站點(diǎn)的數(shù)據(jù)上傳到最近的區(qū)域的S3存儲(chǔ)桶。使用S3跨區(qū)域復(fù)制將對(duì)象復(fù)制到目標(biāo)S3存儲(chǔ)桶。然后從源S3存儲(chǔ)桶中刪除數(shù)據(jù)。這種方式利用了S3跨區(qū)域復(fù)制的功能,但它增加了操作的復(fù)雜性。每個(gè)站點(diǎn)都需要管理一個(gè)S3存儲(chǔ)桶,并且需要配置跨區(qū)域復(fù)制規(guī)則。此外,還需要定期清理源存儲(chǔ)桶中的數(shù)據(jù),增加了管理成本。
C. 不正確。每天安排AWS Snowball Edge存儲(chǔ)優(yōu)化型設(shè)備作業(yè),將數(shù)據(jù)從每個(gè)站點(diǎn)傳輸?shù)阶罱膮^(qū)域。使用S3跨區(qū)域復(fù)制將對(duì)象復(fù)制到目標(biāo)S3存儲(chǔ)桶。AWS Snowball Edge雖然適用于大規(guī)模數(shù)據(jù)傳輸,但這種方式對(duì)于每天500GB的數(shù)據(jù)量來(lái)說(shuō)過(guò)于繁瑣和昂貴。Snowball Edge設(shè)備的調(diào)度、運(yùn)輸和數(shù)據(jù)處理都需要額外的時(shí)間和成本。
D. 不正確。將每個(gè)站點(diǎn)的數(shù)據(jù)上傳到最近的區(qū)域的Amazon EC2實(shí)例。將數(shù)據(jù)存儲(chǔ)在Amazon Elastic Block Store (EBS)卷上。定期拍攝EBS快照,并將其復(fù)制到包含目標(biāo)S3存儲(chǔ)桶的區(qū)域。在該區(qū)域恢復(fù)EBS卷。該解決方案增加了操作的復(fù)雜性。它涉及在多個(gè)區(qū)域管理EC2實(shí)例和EBS卷,定期拍攝快照和復(fù)制快照,以及恢復(fù)快照。這不僅增加了管理成本,而且數(shù)據(jù)傳輸?shù)男室驳陀谥苯邮褂肧3傳輸加速。
