Curious about Actual Isaca Certified Cybersecurity Operations Analyst Exam Questions?

Correct : C

In a containerization environment, all containers running on the same host share the same operating system kernel because:

Container Architecture: Containers virtualize at the OS level, unlike VMs, which have separate OS instances.

Shared Kernel: The host OS kernel is shared across all containers, which makes container deployment lightweight and efficient.

Isolation through Namespaces: While processes are isolated, the underlying OS remains the same.

Docker Example: A Docker host running Linux containers will only support other Linux-based containers, as they share the Linux kernel.

Other options analysis:

A . User data: Containers may share volumes, but this is configurable and not a strict requirement.

B . Database: Containers can connect to the same database but don't necessarily share one.

D . Application: Containers can run different applications even when sharing the same host.

Chapter 9: Secure Systems Configuration: Explains how container environments differ from virtual machines.

Correct : A

A mesh network topology is the most resilient to network failures because:

Redundancy: Each node is interconnected, providing multiple pathways for data to travel.

No Single Point of Failure: If one connection fails, data can still be routed through alternative paths.

High Fault Tolerance: The decentralized structure ensures that the failure of a single device or link does not significantly impact network performance.

Ideal for Critical Infrastructure: Often used in environments where uptime is critical, such as financial or emergency services networks.

Other options analysis:

B . Star: A central hub connects all nodes, so if the hub fails, the entire network collapses.

C . Bus: A single backbone cable means a break in the cable can disrupt the entire network.

D . Ring: Data travels in a circular path; a single break can isolate part of the network unless it is a dual-ring topology.

Chapter 9: Network Design and Architecture: Highlights resilient topologies, including mesh, for secure and fault-tolerant operations.

Correct : D

The Transport layer of the TCP/IP stack is responsible for the reliable transmission of data between hosts.

Protocols: Includes TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).

Reliable Data Delivery: TCP ensures data integrity and order through sequencing, error checking, and acknowledgment.

Flow Control and Congestion Handling: Uses mechanisms like windowing to manage data flow efficiently.

Connection-Oriented Communication: Establishes a session between sender and receiver for reliable data transfer.

Other options analysis:

A . Link: Deals with physical connectivity and media access.

B . Internet: Handles logical addressing and routing.

C . Application: Facilitates user interactions and application-specific protocols (like HTTP, FTP).

CCOA Official Review Manual, 1st Edition Reference:

Chapter 4: Network Protocols and Layers: Details the role of the Transport layer in reliable data transmission.

Chapter 6: TCP/IP Protocol Suite: Explains the functions of each layer.

Correct : B

The cybersecurity objective of integrity ensures that data is accurate, complete, and unaltered. The most direct method to support integrity is the use of digital signatures because:

Tamper Detection: A digital signature provides a way to verify that data has not been altered after signing.

Authentication and Integrity: Combines cryptographic hashing and public key encryption to validate both the origin and the integrity of data.

Non-Repudiation: Ensures that the sender cannot deny having sent the message.

Use Case: Digital signatures are commonly used in secure email, software distribution, and document verification.

Other options analysis:

A . Data backups: Primarily supports availability, not integrity.

C . Least privilege: Supports confidentiality by limiting access.

D . Encryption: Primarily supports confidentiality by protecting data from unauthorized access.

CCOA Official Review Manual, 1st Edition Reference:

Chapter 5: Data Integrity Mechanisms: Discusses the role of digital signatures in preserving data integrity.

Chapter 8: Cryptographic Techniques: Explains how signatures authenticate data.

Correct : C

A poorly enforced Bring Your Own Device (BYOD) policy can lead to the rise of Shadow IT, where employees use unauthorized devices, software, or cloud services without IT department approval. This often occurs because:

Lack of Policy Clarity: Employees may not be aware of which devices or applications are approved.

Absence of Monitoring: If the organization does not track personal device usage, employees may introduce unvetted apps or tools.

Security Gaps: Personal devices may not meet corporate security standards, leading to data leaks and vulnerabilities.

Data Governance Issues: IT departments lose control over data accessed or stored on unauthorized devices, increasing the risk of data loss or exposure.

Other options analysis:

A . Weak passwords: While BYOD policies might influence password practices, weak passwords are not directly caused by poor BYOD enforcement.

B . Network congestion: Increased device usage might cause congestion, but this is more of a performance issue than a security risk.

D . Unapproved social media posts: While possible, this issue is less directly related to poor BYOD policy enforcement.
