1.Will my standby RDS instance be in the same Region as my primary?
A.Only for Oracle RDS types
B.Yes
C.Only if configured at launch
D.No
Answer:B
Yes
Explanation:
- In Amazon RDS Multi-AZ deployments, the standby instance is always in the same AWS Region as the primary instance but in a different Availability Zone (AZ).
- This ensures high availability and automatic failover in case of a failure in the primary AZ.
- Cross-Region replication is not automatic for Multi-AZ deployments but can be achieved using Read Replicas or AWS Database Migration Service (DMS).
2.If I write the below command, what does it do?
ec2-run ami-e3a5408a -n 20 -g appserver
A.Start twenty instances as members of appserver group.
B.Creates 20 rules in the security group named appserver
C.Terminate twenty instances as members of appserver group.
D.Start 20 security groups
Answer:A
Start twenty instances as members of appserver group.
Explanation:
- The command
ec2-run ami-e3a5408a -n 20 -g appserver
is used to launch EC2 instances. ami-e3a5408a
→ Specifies the Amazon Machine Image (AMI) ID.-n 20
→ Specifies the number of instances to launch (20 instances).-g appserver
→ Specifies the security group (appserver
) that the instances will belong to.- This does not create security groups or rules; it simply starts 20 instances using the specified AMI.
3.Out of the stripping options available for the EBS volumes, which one has the following disadvantage : ‘Doubles the amount of I/O required from the instance to EBS compared to RAID 0, because you’re mirroring all writes to a pair of volumes, limiting how much you can stripe.’ ?
A.Raid 0
b.RAID 1+0 (RAID 10)
C.Raid 1
D.Raid
Answer:B
RAID 1+0 (RAID 10)”
Explanation:
- RAID 10 (RAID 1+0) combines striping (RAID 0) and mirroring (RAID 1).
- This means every write operation is mirrored to another volume, effectively doubling the I/O load.
- While it improves fault tolerance, it limits the striping benefits because all writes are duplicated.
- RAID 0 offers high performance but no redundancy.
- RAID 1 provides mirroring but no striping, making it safer but slower for high-write workloads.
4.While performing the volume status checks, if the status is insufficient-data, what does it mean?
A.the checks may still be in progress on the volume
B.the check has passed
C.the check has failed
Answer:A
the checks may still be in progress on the volume
Explanation:
- When performing volume status checks in Amazon EBS, the “insufficient-data” status means that:
- The checks are still in progress.
- AWS has not yet gathered enough information to determine the health of the volume.
- This status is temporary and usually changes to “OK” (if the volume is healthy) or “impaired” (if issues are detected) after a short period.
5.To view information about an Amazon EBS volume, open the Amazon EC2 console at https://console.aws.amazon.com/ec2/, click __________ in the Navigation pane.
A.EBS
B.Describe
C.Details
D.Volumes
Answer:D
Volumes
Explanation:
- In the Amazon EC2 console, to view Amazon EBS volume details, you need to navigate to the “Volumes” section in the left-hand navigation pane.
- This section provides information about:
- Volume status
- Size and type
- Attachments to EC2 instances
- Snapshots and more.
- Other options like “EBS” or “Describe” are not actual menu options in the EC2 console.
