2. Ou created a VPC that has a public subnet and a private subnet. A web server was placed in the public subnet and a database server was placed in the private subnet. The web server is able to connect to the database server; however, the database server at 10.0.1.2 is unable to get software updates. What is the cause of this issue?

There is no NAT gateway for the private subnet, so the database server has no routes that give it public internet access to download software updates.

The database server needs to be assigned a public address from the pool, or assigned an Elastic IP similar to the instance 10.0.0.2.

The router is not configured properly on the VPC. Add a route to route table for the VPC that routes all traffic for 0.0.0.0/0 to the ID of the internet gateway.

There is no egress-only internet gateway attached to the private subnet of the VPC.

Answer

Correct Answer: There is no NAT gateway for the private subnet, so the database server has no routes that give it public internet access to download software updates.

16. What is wrong with the third incoming security group rule, which allows all traffic from sg-269afc5e to go to an Ubuntu EC2 instance configured as a web server?

All traffic on all ports is being denied into this instance, which overwrites the HTTP rule and makes it redundant.

The instance was launched with the default security group, but there is no way for an administrator to SSH into the instance. Add another rule that allows for SSH access from a secured source, such as a single IP or a range of managed IP addresses.

There is nothing wrong with this security group rule. Assuming that sg-269afc5e is applied to other resources that are properly secured, this rule allows all traffic to pass through that is also assigned security group sg-269afc5e.

All traffic on all ports are allowed into this instance. This exposes the instance to all public internet traffic and overwrites the incoming HTTP rule.

Answer

Correct Answer: The instance was launched with the default security group, but there is no way for an administrator to SSH into the instance. Add another rule that allows for SSH access from a secured source, such as a single IP or a range of managed IP addresses.

25. The outbound rules of a security group only allow traffic going to 0.0.0.0/0 on TCP Port 22 (SSH) and TCP port 3306 (MySQL). Review the inbound rules listed in the image below. What is the most important issue to fix with this security group configuration, for an Ubuntu EC2 instance acting as a web server?

The outbound rules block UDP port 53, so the server will not be able to resolve any DNS lookups.

The outbound rules do not allow for HTTP traffic to leave the instance, so inbound HTTP requests will fail because the clients will never get HTTP responses.

The incoming SSH port should not be open to the public. Limit SSH to a single IP address or IP range of controlled addressed, or use a VPN to access the VPC for this server.

The all incoming TCP ports are exposed, which overrides the HTTP and SSH rules and exposes all TCP ports to the public internet.

Assign Elastic IPs to all of the instances and create a group that allows all traffic to pass between each of the five Elastic IP addresses and allow all inbound HTTPS traffic.

Front-end web servers should allow HTTPS. Assign another group to all of the instances that allows all traffic to pass between instances using that group.

Create a security group that allows inbound NFS, HTTP, and HTTPS traffic from all IP addresses. Apply this group to all of the servers.

Create a security group that allows inbound HTTP and HTTPS traffic from all IP addresses and apply this to the web servers. Create a second security group for the NFS filestore that allows outbound NFS traffic to the private IP range of the front-end web servers.

Answer

Correct Answer: Front-end web servers should allow HTTPS. Assign another group to all of the instances that allows all traffic to pass between instances using that group.

59. When using AWS for research and development ahead of a planned migration, how do you prevent unexpected increases or spikes in the billing?

Use the billing dashboard to create a cost budget. Input the max amount you want to be charged each month. Any charges that occur over this amount will cause AWS to automatically suspend those resources

Using the root AWS account, activate IAM access to the billing information for the account. Make sure your IAM users have the Billing FullAccessGroup policy. Then from the billing dashboard, check the accrued charges once a day.

If you are using the AWS free tier, you will have to confirm the usage of any service that goes over the AWS free tier limits.

Using the root AWS account enable Billing Alerts in the user preferences. Then use CloudWatch to create a billing alarm and set a threshold to a specific dollar amount for your estimated monthly charges.

70. Your database is an RDS instance running SQL Server with Multi-AZ replication and you have several older .NET console utilities that perform database operations every 15 seconds. When the cluster has to switch the primary database server to the secondary AZ, the .NET utilities start to report connection failures to the database although other applications are able to access the database. How do you correct this problem?

Use the RDS console to force a reboot of the database instance so that the primary server becomes the master server again.

The server running the .NET utilities is caching the DNS lookup on the database cluster address. Flush the DNS cache of the server and force the C# utilities to open new connections to the database.

A.NET application will retain the IP address of a connection string until the host machine is rebooted.

The NET utilities need to change the SQL Server endpoint in the connection strings to read from the secondary database server using a try/catch.

Answer

Correct Answer: The NET utilities need to change the SQL Server endpoint in the connection strings to read from the secondary database server using a try/catch.
