QUESTION: 89

Between 11:00 a.m. and 1:00 p.m. on workdays, users report that the sales database is either not accessible, sluggish, or difficult to connect to. A cloud administrator discovers that during the impacted time, all hypervisors are at capacity. However, when 70% of the users are using the same database, those issues are not reported.
Which of the following is the most likely cause?

Oversubscription
Resource allocation
Sizing issues
Service quotas

Answer(s): A

Explanation:

The most likely cause of accessibility and performance issues during specific times is oversubscription. This happens when more users are trying to access the database than the hypervisors can handle, due to their resources being allocated to more virtual machines or processes than they can efficiently support.

Reference:

Resource management concepts such as avoiding oversubscription are covered under the Management and Technical Operations domain of the CompTIA Cloud+ exam objectives.

QUESTION: 91

An IT security team wants to ensure that the correct parties are informed when a specific user account is signed in.
Which of the following would most likely allow an administrator to address this concern?

Creating an alert based on user sign-in criteria
Aggregating user sign-in logs from all systems
Enabling the collection of user sign-in logs
Configuring the retention of all sign-in logs

Answer(s): A

Explanation:

To ensure that the correct parties are informed when a specific user account is signed in, the best action is to create an alert based on user sign-in criteria. This alert can notify administrators or security personnel when the specified event occurs.

Reference:

Security monitoring and alerting are critical components of managing cloud environments securely, as discussed in the CompTIA Cloud+ certification.

QUESTION: 92

An on-premises data center is located in an earthquake-prone location. The workload consists of real-time, online transaction processing.
Which ot the following data protection strategies should be used to back up on-premises data to the cloud while also being cost effective?

Remote replication for failover
A copy that is RAID 1 protected on spinning drives in an on-premises private cloud
A full backup to on-site tape libraries in a private cloud
Air-gapped protection to provide cyber resiliency

Answer(s): A

Explanation:

Remote replication for failover is the data protection strategy that should be used to back up on- premises data to the cloud for an earthquake-prone location. It provides real-time or near-real-time copying of data to a remote location, which can be quickly activated in case the primary site fails.

Reference:

Disaster recovery strategies, including remote replication for failover, are part of the cloud-based data protection methods covered in the CompTIA Cloud+ certification.
