NEW QUESTION # 53
A security team is running vulnerability scans against a CI/CD pipeline. The reports show that RDBMS secrets were found hardcoded in Ansible scripts. The RDBMS resides in the internal network but is accessible from a jump server that resides in a public network.
If an attacker gains access to the scripts, what is the risk exposure?
- A. The Ansible scripts run through encrypted SSH connections.
- B. The entire CI/CD-related infrastructure is at risk.
- C. The Automation server is at risk of being compromised.
- D. The internal network is at risk of being compromised.
Answer: D
Explanation:
The internal network is at risk of being compromised if an attacker gains access to the Ansible scripts, as the scripts contain hardcoded secrets for the RDBMS which is accessible from a jump server in a public network. This presents a risk as the secrets can be used to gain access to the RDBMS, and from there, the attacker could potentially gain access to the internal network. Additionally, the entire CI/CD-related infrastructure could be at risk if the attacker is able to gain access to the RDBMS, as they could potentially manipulate the data or scripts in order to cause disruption or damage.

Answer: A
NEW QUESTION # 58
Which step must be taken to enable centralized logging in a Kubernetes environment?
- A. Create a CustomResourceDefinition in each deployment that specifies the IP or names the log collector.
- B. No steps need to be taken. The master node automatically aggregates logs from all worker nodes and stores them on the specified persistent volume.
- C. Deploy a sidecar node that aggregates logs from the entire cluster.
- D. Create a DaemonSet that deploys a container with a logging agent on every node in the cluster.
Answer: D
Explanation:
To enable centralized logging in a Kubernetes environment, you must create a DaemonSet that deploys a container with a logging agent on every node in the cluster. This allows all of the logs from each node to be collected in one place, allowing for easier analysis and management. Reference: Kubernetes Documentation, Logging Architecture.

Answer: B,C
NEW QUESTION # 65
Refer to the exhibit.
The IT team is creating a new design for a logging system. The system must be able to collect logs from different components of the infrastructure using the SNMP protocol. When the data is collected it will need to be presented in a graphical UI to the NOC team.
What is the architectural component that needs to be placed in the unlabeled box to complete this design?
- A. time-series database
- B. log parser
- C. message queue
- D. web server
Answer: B
Explanation:
Explanation
A log parser is a software component that is used to collect and parse log data from various sources, such as infrastructure devices, applications, and services. It is responsible for collecting log data from the various sources and then mapping it to a specific format that can be easily consumed and interpreted by the NOC team. The log parser can also be used to filter out irrelevant data and store the processed data in a time-series database. This data can then be used by the NOC team to generate visualizations and reports, which will help them identify and address any issues within the infrastructure.

NEW QUESTION # 70
A team must roll out updates on the production instance of an application. To avoid any service down time, the new version must be released alongside the old version. After the team ensures that the new version operates as it should, traffic will be redirected to the new version. Then the old version will be shut down.
Which deployment strategy must be used?
- A. shadow
- B. rolling
- C. canary
- D. blue/green
Answer: D
Explanation:
The new version of the application is deployed to one of the environments, and then traffic is gradually shifted to the updated environment. This strategy allows the team to test the new version before releasing it to the public, ensuring that it is operating as expected. After the new version is tested and approved, traffic is fully shifted to the new environment and the old environment is shut down.
