AWS Certified SysOps Administrator - Associate - Part 49

1. A user has created a VPC subnets with public and private using the VPC Wizard. The VPC CIDR 20.0.0.0/16. The private subnet using CIDR 20.0.0.0/24. The NAT instance ID is i-A12345. Which of the entries listed below are required in the main draw of the attached itinerary with the private subnet to allow the case to connect to the Internet?

A) Destination: 20.0.0.0/0 and Target i-A12345
B) Destination: 0.0.0.0/0 and Target i-A12345
C) Destination: 20.0.0.0/0 and Target: 80
D) None
E) Destination: 20.0.0.0/24 and Target i al-2345


2. A user configured with ELB setting auto scale. The user has suspended the automatic scaling Alarm Notification (which alerts for alarms Auto Scaling Cloud Watch. Process for a while. What Auto Scaling do during this period?

A) AWS will receive alarms, but will not perform Auto Scaling Policy
B) AWS will not receive alarms Cloud Watching
C) Auto Scaling will execute the policy, but it will not initiate proceedings until the process resumes
D) None
E) It is impossible to suspend alarm notification process


3. A user has created a VPC with public and private subnets using the VPC Wizard. The VPC has 20.0.0.0/1 CIDR 6. The public subnet using CIDR 20.0.1 .0 / 24. The user is planning to host one in the public subnet web server (port 80 and a DB server in the private subnet (port 3306 .. the user configures a security group for the subnet public (GRP Web Sec. And the private subnet (DB Dry GRP .. Among the entries mentioned below is needed in the basic safety group subnet private data (DB GRP Sec.?

A) Allow entering port 3306 source 20.0.0.0/16
B) Allow Outbound on port 3306 for Destination Web Server Security Group (GRP Web Sec.)
C) Allow Outbound port 80 for Destination NAT IP instance
D) None
E) Allow entering port 3306 for the security group Source Web Server (Web Sec GRP)


4. A user tries to connect to a running EC2 instance running using SSH. However, the user gets a host not found error key. Which of the options mentioned below is a possible reason for rejection?

A) None
B) The passkey to connect to the instance is incorrect
C) The security group is not configured correctly
D) The instance CPU is heavily loaded
E) The user provides the wrong user name for the connection OS


5. A user configured with ELB setting auto scale. The user has suspended the auto scale Add Load Balancer (which adds instances to process load balancer. For a time. What will happen to proceedings initiated during the period of suspension?

A) It is impossible to suspend only the Add to charging process Balancer
B) None
C) Auto Scaling will not launch proceedings during this period due to the suspension process
D) The case will not be registered with ELB and the user must manually register when the process resumes
E) Cases will be registered with ELB once the process has taken


1. Right Answer: B
Explanation: A user can create a subnet with the VPC instances and run within that subnet. If the user has created a public-private subnet, subnet public bodies can receive incoming traffic directly from the Internet, while private subnet bodies can not. If these subnets are created with the wizard, AWS create two routing tables and join the subnets. The main routing table will have the input destination: 0.0.0.0/0 and Target: all 2345K, allowing all private subnet instances to connect to the Internet using NAT.

2. Right Answer: A
Explanation: It is impossible to suspend alarm notification process

3. Right Answer: E
Explanation: A user can create a subnet with the VPC instances and run within that subnet. If the user has created a public-private subnet to respectively host the web server and the DB server, the user must configure the private subnet instances can receive incoming traffic from public subnet on port DB. So, configure port 3306 by entering with the source Web server security group (GRP Sec Web. The user must configure ports 80 and 443 for destination 0.0.0.0/0 as the routing table directs traffic to NAT instance net privates.

4. Right Answer: E
Explanation: If the user tries to connect to an instance EC2 Linux and receives host not found error Key probable reasons are: The private key pair is not just the login user name is wrong

5. Right Answer: D
Explanation: Auto Scaling performs various processes, such as the launch Terminate, add Load Balancer etc. The user can also suspend individual process. Add the load balancer process type adds instances to the load balancer when instances are launched. If this process is suspended, Auto Scaling launch instances but not add to the load balancing. When the user takes this process, Auto Scaling will resume adding new authorities launched after the resumption to the load balancer. However, it will not add running instances that were started while the process was suspended; these cases must be added manually are
