A company needs to manage Amazon EC2 instances through command line interfaces for Linux hosts and Windows hosts. The EC2 instances are deployed in an environment in which there is no route to the internet. The company must implement role-based access control for management of the instances. The company has a standalone on-premises environment.
Which approach will meet these requirements with the LEAST maintenance overhead?
A company is planning to host external websites on AWS. The websites will include multiple tiers such as web servers, application logic services, and databases. The company wants to use AWS Network Firewall. AWS WAR and VPC security groups for network security.
The company must ensure that the Network Firewall firewalls are deployed appropriately within relevant VPCs. The company needs the ability to centrally manage policies that are deployed to Network Firewall and AWS WAF rules. The company also needs to allow application teams to manage their own security groups while ensuring that the security groups do not allow overly permissive access.
What is the MOST operationally efficient solution that meets these requirements?
A company ran out of IP address space in one of the Availability Zones in an AWS Region that the company uses. The Availability Zone that is out of space is assigned the
10.10.1.0/24 CIDR block. The company manages its networking configurations in an AWS CloudFormation stack. The company's VPC is assigned the 10.10.0.0/16 CIDR
block and has available capacity in the 10.10.1.0/22 CIDR block.
How should a network specialist add more IP address space in the existing VPC with the LEAST operational overhead?
An AWS CloudFormation template is being used to create a VPC peering connection between two existing operational VPCs, each belonging to a different AWS account. All necessary components in the 'Remote' (receiving) account are already in place.
The template below creates the VPC peering connection in the Originating account. It contains these components:
AWSTemplateFormation Version: 2010-09-09
Parameters:
Originating VCId:
Type: String
RemoteVPCId:
Type: String
RemoteVPCAccountId:
Type: String
Resources:
newVPCPeeringConnection:
Type: 'AWS::EC2::VPCPeeringConnection'
Properties:
VpcdId: !Ref OriginatingVPCId
PeerVpcId: !Ref RemoteVPCId
PeerOwnerId: !Ref RemoteVPCAccountId
Which additional AWS CloudFormation components are necessary in the Originating account to create an operational cross-account VPC peering connection with AWS CloudFormation? (Select two.)
A Network Engineer is provisioning a subnet for a load balancer that will sit in front of a fleet of application servers in a private subnet. There is limited IP space left in the VPC CIDR. The application has few users now but is expected to grow quickly to millions of users.
What design will use the LEAST amount of IP space, while allowing for this growth?
