Question 1
A company is migrating a three-tier application to the cloud. The
application consists of web servers, application servers, and a database.
During periods of unpredictable demand, the web tier experiences
significant traffic spikes while the database workload remains relatively
stable. The company wants to scale only the components that require
additional capacity without provisioning unnecessary resources. Which
cloud architecture BEST addresses this requirement?
A. Deploy all three tiers on identical virtual machines and scale them
simultaneously
B. Implement independent horizontal scaling for each application tier
C. Deploy the entire application on a single large virtual machine
D. Use vertical scaling exclusively for the database and web tiers
Answer: B. Implement independent horizontal scaling for each
application tier
Rationale: Independent horizontal scaling allows each tier to increase
or decrease capacity according to its individual workload. The web tier
can scale out during traffic spikes while the database and application
tiers remain appropriately sized. This improves elasticity and cost
efficiency.

,Question 2
A cloud administrator is designing an application that must remain
operational if an entire availability zone becomes unavailable. The
application currently has all compute instances and its database located
in one availability zone. Which architecture provides the BEST
resilience?
A. Deploy multiple instances within the same availability zone
B. Deploy instances across multiple availability zones and implement
database replication
C. Increase the CPU and memory of the existing instances
D. Create additional snapshots within the same availability zone
Answer: B. Deploy instances across multiple availability zones and
implement database replication
Rationale: Availability zones are designed as separate failure domains.
Distributing compute resources and replicating the database across
zones protects against zone-level failures. Increasing instance size or
creating snapshots in the same zone does not provide equivalent
availability protection.
Question 3
A company wants to reduce its cloud bill. Monitoring shows that several
development virtual machines remain powered on 24 hours a day even
though developers use them only during business hours. Which action
should the administrator take FIRST?
A. Increase the CPU allocation of the development systems
B. Configure automated schedules to shut down unused development
resources
C. Migrate all development systems to dedicated hosts
D. Purchase additional reserved capacity
2
,Answer: B. Configure automated schedules to shut down unused
development resources
Rationale: Automated shutdown schedules directly eliminate
unnecessary compute consumption. Development systems that are not
needed outside business hours should not continue generating
compute charges.
Question 4
An organization requires a cloud application to continue operating when
an individual virtual machine fails. Which mechanism BEST provides
this capability?
A. RAID on the virtual machine's boot disk
B. High availability through redundant instances and automated failover
C. Increasing the virtual machine's disk size
D. Creating a manual backup once per month
Answer: B. High availability through redundant instances and
automated failover
Rationale: High availability requires redundancy and an automated
mechanism capable of redirecting workloads when an instance fails. A
larger disk or periodic backup does not provide continuous service
availability.
Question 5
A cloud administrator observes that an application has unpredictable
traffic patterns. The application is heavily used during certain periods
but experiences very low demand at other times. Which cloud
characteristic BEST addresses this situation?
3
, A. Elasticity
B. Data sovereignty
C. Non-repudiation
D. Fault isolation
Answer: A. Elasticity
Rationale: Elasticity is the ability to dynamically increase or decrease
resources as workload requirements change. This is particularly
useful for unpredictable workloads because resources can be added
during demand spikes and removed when demand decreases.
Question 6
An organization is deploying a cloud application that must handle
millions of requests. The administrator wants traffic distributed across
multiple application servers so that no individual server becomes
overloaded. Which technology should be implemented?
A. Load balancer
B. Hypervisor
C. DNS resolver only
D. Tape library
Answer: A. Load balancer
Rationale: A load balancer distributes incoming traffic across multiple
backend servers. It improves scalability, availability, and performance
while preventing individual servers from becoming bottlenecks.
Question 7
A company wants to ensure that cloud resources can be automatically
created from a standardized configuration. Administrators currently
