You are designing Internet connectivity for your VPC. The Web servers must be available on the Internet. The
application must have a highly available architecture.
Which alternatives should you consider? (Choose 2 answers)
A.
Configure a NAT instance in your VPC Create a default route via the NAT instance and associate it with all
subnets Configure a DNS A record that points to the NAT instance public IP address.
B.
Configure a CloudFront distribution and configure the origin to point to the private IP addresses of your
Web servers Configure a Route53 CNAME record to your CloudFront distribution.
C.
Place all your web servers behind EL8 Configure a Route53 CNMIE to point to the ELB DNS name.
D.
Assign BPs to all web servers. Configure a Route53 record set with all EIPs. With health checks and DNS
failover.
E.
Configure ELB with an EIP Place all your Web servers behind ELB Configure a Route53 A record that points to
the EIP.
B and D
Sorry C and D
C and E
D. IOPs can’t offers a 100% uptime guarantee.

B & E
Wondering if we can use CNAME to point to cloud distribution…has to be A record alias.
Any thoughts welcome
Option A: NAT instance doesn’t make a sense here
Option E: ELB with an EIP (we assign EIP’s to instances)
So A&E are ruled out. Choosing between B,C & D
Option B is wrong as it says “origin to point to the private IP addresses of your
Web servers” (Private IP Address pointing)
So Answer –> C&D
B is wrong. not be private IP addresses.
C & C
C & D

I agree with umesh
Route53 has to use A record alias to work with ELB.

C & D are the right answers.
C, D
C is possible if the domain is not an apex domain and hence C is feasible assuming website will start with subdomain http://WWW.domainname.com
D is feasible
I am not sure if Cloudfront can talk to any AWS resource on private IPs. If yes B could have been a more approprate response
C. Place all your web servers behind ELB Configure a Route53 CNMIE to point to the ELB
DNS name.
D. Assign EIPs to all web servers. Configure a Route53 record set with all EIPs. With
health checks and DNS failover.
I sure hope the actual exam has fewer typos (or scanning errors). I was trying to figure out how we assign British Petroleum to all of the web servers.
– C.Place all your web servers behind EL8 Configure a Route53 CNAME to point to the ELB DNS name.
– D.Assign EIPs to all web servers. Configure a Route53 record set with all EIPs. With health checks and DNS
