NEW QUESTION 47
A global medical research company has a molecular imaging system that provides each client with frequently updated images of what is happening inside the human body at the molecular and cellular levels. The system is hosted in AWS and the images are hosted in an S3 bucket behind a CloudFront web distribution. When a fresh batch of images is uploaded to S3, it is required to keep the previous ones in order to prevent them from being overwritten.
Which of the following is the most suitable solution to solve this issue?
- A. Add Cache-Control no-cache, no-store, or private directives in the S3 bucket
- B. Use versioned objects
- C. Add a separate cache behavior path for the content and configure a custom object caching with a Minimum TTL of 0
- D. Invalidate the files in your CloudFront web distribution
Answer: B
Explanation:
To control the versions of files that are served from your distribution, you can either invalidate files or give them versioned file names. If you want to update your files frequently, AWS recommends that you primarily use file versioning for the following reasons:
- Versioning enables you to control which file a request returns even when the user has a version cached either locally or behind a corporate caching proxy. If you invalidate the file, the user might continue to see the old version until it expires from those caches.
- CloudFront access logs include the names of your files, so versioning makes it easier to analyze the results of file changes.
- Versioning provides a way to serve different versions of files to different users.
- Versioning simplifies rolling forward and back between file revisions.
- Versioning is less expensive. You still have to pay for CloudFront to transfer new versions of your files to edge locations, but you don't have to pay for invalidating files.
Invalidating the files in your CloudFront web distribution is incorrect because even though using invalidation will solve this issue, this solution is more expensive as compared to using versioned objects.
Adding a separate cache behavior path for the content and configuring a custom object caching with a Minimum TTL of 0 is incorrect because this alone is not enough to solve the problem. A cache behavior is primarily used to configure a variety of CloudFront functionality for a given URL path pattern for files on your website. Although this solution may work, it is still better to use versioned objects where you can control which image will be returned by the system even when the user has another version cached either locally or behind a corporate caching proxy.
Adding Cache-Control no-cache, no-store, or private directives in the S3 bucket is incorrect because although it is right to configure your origin to add the Cache-Control or Expires header field, you should do this to your objects and not on the entire S3 bucket.

NEW QUESTION 48
An aerospace engineering company recently adopted a hybrid cloud infrastructure with AWS. One of the Solutions Architect's tasks is to launch a VPC with both public and private subnets for their EC2 instances as well as their database instances.
Which of the following statements are true regarding Amazon VPC subnets? (Select TWO.)
- A. Every subnet that you create is automatically associated with the main route table for the VPC.
- B. Each subnet spans to 2 Availability Zones.
- C. The allowed block size in VPC is between a /16 netmask (65,536 IP addresses) and /27 netmask (32 IP addresses).
- D. Each subnet maps to a single Availability Zone.
- E. EC2 instances in a private subnet can communicate with the Internet only if they have an Elastic IP.
Answer: A,D
Explanation:
A VPC spans all the Availability Zones in the region. After creating a VPC, you can add one or more subnets in each Availability Zone. When you create a subnet, you specify the CIDR block for the subnet, which is a subset of the VPC CIDR block. Each subnet must reside entirely within one Availability Zone and cannot span zones. Availability Zones are distinct locations that are engineered to be isolated from failures in other Availability Zones. By launching instances in separate Availability Zones, you can protect your applications from the failure of a single location.
Below are the important points you have to remember about subnets:
- Each subnet maps to a single Availability Zone.
- Every subnet that you create is automatically associated with the main route table for the VPC.
- If a subnet's traffic is routed to an Internet gateway, the subnet is known as a public subnet.
The option that says: EC2 instances in a private subnet can communicate with the Internet only if they have an Elastic IP is incorrect. EC2 instances in a private subnet can communicate with the Internet not just by having an Elastic IP, but also with a public IP address via a NAT Instance or a NAT Gateway. Take note that there is a distinction between private and public IP addresses. To enable communication with the Internet, a public IPv4 address is mapped to the primary private IPv4 address through network address translation (NAT).
The option that says: The allowed block size in VPC is between a /16 netmask (65,536 IP addresses) and /27 netmask (32 IP addresses) is incorrect because the allowed block size in VPC is between a /16 netmask (65,536 IP addresses) and /28 netmask (16 IP addresses) and not /27 netmask.
The option that says: Each subnet spans to 2 Availability Zones is incorrect because each subnet must reside entirely within one Availability Zone and cannot span zones. References:

NEW QUESTION 49
A top IT Consultancy has a VPC with two On-Demand EC2 instances with Elastic IP addresses. You were notified that the EC2 instances are currently under SSH brute force attacks over the Internet. The IT Security team has identified the IP addresses where these attacks originated. You have to immediately implement a temporary fix to stop these attacks while the team is setting up AWS WAF, GuardDuty, and AWS Shield Advanced to permanently fix the security vulnerability.
Which of the following provides the quickest way to stop the attacks to the instances?
- A. Block the IP addresses in the Network Access Control List
- B. Remove the Internet Gateway from the VPC
- C. Place the EC2 instances into private subnets
- D. Assign a static Anycast IP address to each EC2 instance
Answer: A
Explanation:
A network access control list (ACL) is an optional layer of security for your VPC that acts as a firewall for controlling traffic in and out of one or more subnets. You might set up network ACLs with rules similar to your security groups in order to add an additional layer of security to your VPC.
The following are the basic things that you need to know about network ACLs:
- Your VPC automatically comes with a modifiable default network ACL. By default, it allows all inbound and outbound IPv4 traffic and, if applicable, IPv6 traffic.
- You can create a custom network ACL and associate it with a subnet. By default, each custom network ACL denies all inbound and outbound traffic until you add rules.
- Each subnet in your VPC must be associated with a network ACL. If you don't explicitly associate a subnet with a network ACL, the subnet is automatically associated with the default network ACL.
- You can associate a network ACL with multiple subnets; however, a subnet can be associated with only one network ACL at a time. When you associate a network ACL with a subnet, the previous association is removed.
- A network ACL contains a numbered list of rules that we evaluate in order, starting with the lowest numbered rule, to determine whether traffic is allowed in or out of any subnet associated with the network ACL. The highest number that you can use for a rule is 32766. We recommend that you start by creating rules in increments (for example, increments of 10 or 100) so that you can insert new rules where you need to later on.
- A network ACL has separate inbound and outbound rules, and each rule can either allow or deny traffic.
- Network ACLs are stateless; responses to allowed inbound traffic are subject to the rules for outbound traffic (and vice versa).
The scenario clearly states that it requires the quickest way to fix the security vulnerability. In this situation, you can manually block the offending IP addresses using Network ACLs since the IT Security team already identified the list of offending IP addresses. Alternatively, you can set up a bastion host, however, this option entails additional time to properly set up as you have to configure the security configurations of your bastion host.
Hence, blocking the IP addresses in the Network Access Control List is the best answer since it can quickly resolve the issue by blocking the IP addresses using Network ACL.
Placing the EC2 instances into private subnets is incorrect because if you deploy the EC2 instance in the private subnet without public or EIP address, it would not be accessible over the Internet, even to you.
Removing the Internet Gateway from the VPC is incorrect because doing this will also make your EC2 instance inaccessible to you as it will cut down the connection to the Internet.
Assigning a static Anycast IP address to each EC2 instance is incorrect because a static Anycast IP address is primarily used by AWS Global Accelerator to enable organizations to seamlessly route traffic to multiple regions and improve availability and performance for their end-users.
