Question 2
Which method is most effective to prevent lateral movement among compromised hosts within a secure network?

(A) Implementing end-to-end encryption solely within each host.

(B) Network segmentation and micro-segmentation to isolate hosts.

(C) Using a firewall with fixed, static rules only.

(D) Relying exclusively on antiviruses installed on individual systems.

Question 3
In a dynamic cloud environment with auto-scaling services, which firewall deployment is most suitable?

(A) A Next-Generation Firewall (NGFW) that supports automated policy adjustments.

(B) A legacy stateful inspection firewall with static and manual rules.

(C) A distributed proxy without centralized policy management.

(D) A single perimetral firewall with an unchanging configuration.

Question 4
When configuring network access control for disparate cloud services, what is the primary benefit of implementing a Zero Trust Architecture?

(A) It permits packet filtering only at the network perimeter.

(B) It eliminates the need for continuous internal traffic monitoring.

(C) It enforces strict, continuous verification for every access request regardless of network location.

(D) It allows implicit trust based solely on traditional IP addresses.

Question 5
What distinguishes asymmetric encryption in cloud storage applications?

(A) It is less computationally intensive compared to symmetric encryption protocols.

(B) It primarily relies on a shared secret key like symmetric encryption does.

(C) It generally encrypts data faster than symmetric methods, suitable for large datasets.

(D) It uses paired public-private keys that enable secure key exchanges without a pre-shared secret.

Question 6
How does host-based encryption differ from network-level encryption in protecting cloud data?

(A) Network-level encryption is used to secure stored data on physical hardware.

(B) Host-based encryption only protects data during transmission between endpoints.

(C) Host-based encryption secures data at the local machine level, independent of data in transit.

(D) Network-level encryption is inherently more secure because it covers the entire network.

Question 7
In the context of cloud-based identity management, what is a key advantage of employing SAML-based Single Sign-On (SSO)?

(A) It streamlines user access by allowing one set of credentials across multiple services.

(B) It enforces unique credentials for every individual application.

(C) It prevents the formation of federated identities across platforms.

(D) It reduces overall security by centralizing the authentication process.

Question 8
Which scenario best demonstrates the necessity of employing robust API security in cloud services?

(A) Unauthorized access attempts via exposed API endpoints that control critical cloud resources.

(B) Physical theft of a server from a data center facility.

(C) Traditional VPN usage connecting remote sites securely.

(D) The use of outdated, legacy systems that are not connected to the internet.

Question 9
What is the primary risk associated with misconfigured security groups in a cloud environment?

(A) Increased operational costs from over-provisioned virtual machines.

(B) Accidental exposure of sensitive resources to public networks.

(C) Reduced network performance due to processing overhead from encryption.

(D) Failure of internal logging systems due to configuration mismatches.

Question 10
In encryption key management for cloud environments, why is the use of a Hardware Security Module (HSM) recommended?

(A) It primarily improves application performance by offloading encryption to software processes.

(B) It distributes encryption keys automatically across nodes without any additional controls.

(C) It provides tamper-resistant storage and robust cryptographic operations for key management.

(D) It eliminates the need to periodically rotate encryption keys.

Question 11
Which cloud security strategy is most effective in mitigating the impact of Distributed Denial of Service (DDoS) attacks?

(A) Relying solely on traditional on-premise firewalls to filter all incoming traffic.

(B) Disabling network traffic logging to maintain performance during an attack.

(C) Using static IP whitelisting as the only form of security control.

(D) Utilizing scalable cloud-based DDoS mitigation services with traffic scrubbing.

Question 12
What is a key advantage of integrating encryption with Data Loss Prevention (DLP) systems in cloud environments?

(A) It reduces the need for comprehensive identity management controls.

(B) It allows unrestricted internal sharing of data without governance.

(C) It eliminates issues related to data availability in cloud storage.

(D) It ensures encrypted data, even if exfiltrated, remains inaccessible to unauthorized parties.

Question 13
In network security within cloud settings, what role does an Intrusion Detection System (IDS) primarily serve?

(A) It adds unnecessary complexity without offering substantive protection.

(B) It encrypts data packets in real time to prevent unauthorized access.

(C) It replaces all other security mechanisms as a singular defense solution.

(D) It monitors network traffic to detect and alert on suspicious or anomalous activities.

Question 14
How do log aggregation tools enhance the security posture of a cloud infrastructure?

(A) They simply store logs without offering any automated analytics or correlation.

(B) They operate only on encrypted logs, complicating forensic analysis.

(C) They require manual log review, making real-time monitoring impractical.

(D) They consolidate and correlate logs from diverse sources to detect patterns of anomalous behavior.

Question 15
Which practice is most important for ensuring the resilience and security of identity management systems in a cloud environment?

(A) Using outdated authentication protocols to maintain compatibility with legacy systems.

(B) Sharing administrator credentials across various departments for convenience.

(C) Relying entirely on legacy password policies without periodic updates.

(D) Implementing regular, automated audits and access reviews to detect any anomalies.
