The AWS Certified Advanced Networking – Specialty (ANS-C01) exam validates your skills in designing and implementing AWS networking solutions. It is suitable for networking professionals looking to specialize in AWS.
You are configuring a security group. What happens if you add an inbound rule that allows 0.0.0.0/0 on TCP port 22?
ASSH is restricted to internal IPs
BAny IP can SSH into the instance
CSSH is disabled on the instance
DOnly AWS can access the instance
Explanation
Allowing 0.0.0.0/0 on TCP port 22 opens SSH access to any IP address, which is generally unsafe.
Q52
Which service is used for high-performance computing in AWS?
AAmazon EC2
BAmazon S3
CAWS Lambda
DAmazon RDS
Explanation
Amazon EC2 is designed for high-performance computing, while the others serve different functions.
Q53
A company needs to connect its on-premises network to AWS securely and consistently. Which hybrid solution should they consider?
AAWS Direct Connect
BAWS VPN
CAmazon Route 53
DAWS Transit Gateway
Explanation
AWS Direct Connect provides a dedicated line for secure connectivity, unlike the others which do not offer dedicated options.
Q54
You are configuring an AWS VPC with subnets. What happens when you create a route in the route table to a public subnet?
AAccess to the internet is blocked.
BInstances cannot communicate internally.
CInstances gain internet access.
DRoutes are ignored by AWS.
Explanation
Creating a route to a public subnet allows instances to access the internet directly, while others incorrectly describe the outcome.
Q55
Which service allows you to automate network configurations?
AAWS Config
BAWS CloudFormation
CAWS Elastic Beanstalk
DAWS OpsWorks
Explanation
AWS CloudFormation automates infrastructure setup using templates; others do not primarily focus on automation of network configurations.
Q56
A company needs to ensure their VPC security while allowing internal applications to communicate. Which solution best fits this requirement?
AUse public IPs for all services
BImplement security groups and network ACLs
CConfigure a VPN connection
DUse NAT Gateways exclusively
Explanation
Security groups and network ACLs manage internal traffic effectively; other options either expose the network or don’t facilitate internal communication optimally.
Q57
What happens when you set an incorrect route table to your VPC subnet?
AVPC becomes unreachable
BInstances lose internet access
CInstances receive incorrect IPs
DNetwork latency increases
Explanation
Setting an incorrect route table generally hinders internet access for instances; it does not make the VPC unreachable or affect IP addressing or latency directly.
Q58
Which AWS service automatically adjusts capacity based on demand?
AAWS Auto Scaling
BAmazon S3
CAmazon CloudFront
DAWS Lambda
Explanation
AWS Auto Scaling dynamically manages resources; others do not automatically adjust capacity.
Q59
A company needs to securely manage access to AWS resources. What should they use?
AAWS IAM Roles
BAmazon EC2 Security Groups
CAWS CloudTrail
DAmazon Route 53
Explanation
AWS IAM Roles provide secure access control; other options do not manage access directly.
Q60
You are configuring a VPC peering connection. What happens when the CIDR blocks overlap?
APeering succeeds with warnings.
BPeering fails to establish.
CTraffic is automatically rerouted.
DOverlap is ignored.
Explanation
Peering fails when CIDR blocks overlap; others misrepresent the outcome.
