Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q750-Q755):

NEW QUESTION # 750
A company runs an application in a VPC on AWS. The company's on-premises data center has a DNS server. The data center is connected to AWS through an AWS Direct Connect connection with a private virtual interface (VIF). The on-premises DNS server needs to resolve the DNS name of the application in the VPC.

Answer: D

Explanation:
When on-premises DNS servers need to resolve private DNS names in a VPC, the correct pattern is to create a Route 53 Resolver inbound endpoint. The inbound endpoint allows DNS queries to flow from the on-premises environment into the VPC, where Route 53 can resolve VPC-specific names (such as private hosted zones or private resource records). Outbound endpoints (C) are for sending VPC DNS queries to on-premises, not the reverse. Verified Access (A) is unrelated to DNS resolution. Direct Connect (B) provides network connectivity but does not provide DNS forwarding capabilities. Therefore, option D is the correct design.

* AWS Well-Architected Framework - Security Pillar: Hybrid DNS integration


NEW QUESTION # 751
A company needs to store its accounting records in Amazon S3. The records must be immediately accessible for 1 year and then must be archived for an additional 9 years. No one at the company, including administrative users and root users, can be able to delete the records during the entire 10-year period. The records must be stored with maximum resiliency.
Which solution will meet these requirements?

Answer: D


NEW QUESTION # 752
A company has an application that runs on Amazon EC2 instances and uses an Amazon Aurora database. The EC2 instances connect to the database by using user names and passwords that are stored locally in a file. The company wants to minimize the operational overhead of credential management.
What should a solutions architect do to accomplish this goal?

Answer: C


NEW QUESTION # 753
Which solution will meet these requirements MOST cost-effectively?

Answer: C

Explanation:
EBS gp3 volumes allow you to independently configure IOPS and throughput, up to 16,000 IOPS, regardless of the volume size, and at a lower cost compared to io1/io2 provisioned IOPS volumes. This meets the requirement for cost-effective, predictable IOPS performance for Amazon RDS for PostgreSQL.
AWS Documentation Extract:
"With gp3 volumes, you can provision performance independent of storage capacity, up to 16,000 IOPS. This allows for cost-effective scaling for applications that require high performance at a lower price point compared to io1." (Source: Amazon EBS documentation, gp3 Volumes)
* A: gp2 ties IOPS to volume size; 5 TiB is wasteful if only 15,000 IOPS are needed.
* B: io1 works but is significantly more expensive than gp3 for most workloads.
* D: Magnetic volumes do not support high IOPS.

NEW QUESTION # 754
A company needs to use Amazon S3 to store irreproducible financial documents. For their quarterly reporting, the files are required to be retrieved after a period of 3 months. There will be some occasions when a surprise audit will be held, which requires access to the archived data that they need to present immediately.
What will you do to satisfy this requirement in a cost-effective way?

Answer: D

Explanation:
In this scenario, the requirement is to have a storage option that is cost-effective and has the ability to access or retrieve the archived data immediately. The cost-effective options are Amazon Glacier Deep Archive and Amazon S3 Standard- Infrequent Access (Standard - IA). However, the former option is not designed for rapid retrieval of data which is required for the surprise audit.
Hence, using Amazon Glacier Deep Archive is incorrect and the best answer is to use Amazon S3 Standard - Infrequent Access.

Using Amazon S3 Standard is incorrect because the standard storage class is not cost-efficient in this scenario. It costs more than Glacier Deep Archive and S3 Standard - Infrequent Access.
Using Amazon S3 -Intelligent Tiering is incorrect because the Intelligent Tiering storage class entails an additional fee for monitoring and automation of each object in your S3 bucket vs. the Standard storage class and S3 Standard - Infrequent Access.
Amazon S3 Standard - Infrequent Access is an Amazon S3 storage class for data that is accessed less frequently but requires rapid access when needed. Standard - IA offers the high durability, throughput, and low latency of Amazon S3 Standard, with a low per GB storage price and per GB retrieval fee. This combination of low cost and high performance makes Standard - IA ideal for long-term storage, backups, and as a data store for disaster recovery. The Standard - IA storage class is set at the object level and can exist in the same bucket as Standard, allowing you to use lifecycle policies to automatically transition objects between storage classes without any application changes.
