Question 2

After a virtualized host is rebooted, ten guest VMs take a long time to start, and extensive memory utilization is observed. Which of the following should be done to optimize the host?

AReduce the host memory assignment.

BConfigure the virtual/swap memory configuration on the guest VMs.

CIncrease the allocated vCPUs per VM.

DReduce the allocated memory and enable dynamic memory.

Answer : D

Detailed

D . Reduce the allocated memory and enable dynamic memory: Allocating excessive memory to VMs can lead to slow performance during initialization. Dynamic memory allows the system to allocate resources as needed, optimizing performance and resource use.

Question 3

A systems administrator is diagnosing performance issues on a web application. The web application sends thousands of extremely complex SQL queries to a database server, which has trouble retrieving the information in time. The administrator checks the database server and notes the following resource utilization:

CPU: 64%

RAM: 97%

Network throughput: 384/1000 Kbps

Disk throughput: 382,700 Kbps

The administrator also notices that the storage for the database server is consistently near its IOPS limit. Which of the following will best resolve these performance issues?

AIncrease CPU resources on the database server.

BIncrease caching on the database server.

CPut the storage and the database on the same VLAN.

DEnable compression on storage traffic.

EEnable deduplication on the storage appliance.

Answer : B

Detailed

B . Increase caching on the database server: Increasing caching reduces the need for repetitive queries to access disk storage, alleviating the IOPS bottleneck and improving overall performance.

Question 4

One of the web applications in a public subnet is vulnerable to a newly discovered zero-day vulnerability. Which of the following actions can a security engineer perform to reduce the risk of exploitation and application downtime?

AStop the web server in the affected host.

BInsert a deny rule in the host firewall.

CAdd a new signature in the network IDS.

DImplement a virtual patch in the WAF.

Answer : D

Detailed

D . Implement a virtual patch in the WAF: A virtual patch in the Web Application Firewall (WAF) provides immediate protection against a zero-day vulnerability by filtering malicious traffic, without requiring downtime for system updates.

Question 5

A company recently acquired another company, and the human resources staff expects to see a 50% increase in usage for the employee benefits web portal once the employees from the acquired company receive access. The cloud administrator needs to assess whether the current web portal can handle the increased load. Which of the following should the cloud administrator do first?

AIncrease CPU resources by 50% on the web portal.

BReview current monitoring logs to determine resource usage on the web portal.

CCreate an autoscaling policy to expand the web portal environment dynamically.

DProvision additional servers to handle the expected increased usage.

Answer : B

Detailed

B . Review current monitoring logs to determine resource usage on the web portal: Reviewing logs helps the administrator understand current resource utilization and identify whether the current setup can handle additional load before making changes.

Question 6

An organization's security team must determine the likelihood of a breach on its external-facing websites. Which of the following would be best to identify the organization's chances of incurring a breach?

ARegression testing.

BFunctional testing.

CVulnerability scanning.

DPenetration testing.

Answer : D

Detailed

D . Penetration testing: Penetration tests simulate real-world attacks to uncover vulnerabilities and evaluate the likelihood of exploitation, providing actionable insights for remediation.

Question 7

A systems administrator is reviewing the application development process with the development team and notices that the team has no way to collaboratively develop code. Which of the following methods should be implemented to resolve this issue?

AContinuous deployment.

BVersion control.

CChange management.

DConfiguration management.

Answer : B

Detailed

B . Version control: Version control systems like Git enable collaborative development, allowing team members to track changes, merge contributions, and resolve conflicts efficiently.
