To improve security, the security team at a growing tech
company aims to update its infrastructure. They explore different
architecture models and ponder the implications of logical
segmentation. To curb lateral movement within the network (in
case an intruder accesses one segment), the team plans to split
the network into smaller, isolated segments, each boasting its own
resources and security controls. Considering this strategy to boost
security, which architecture model would optimally support the
logical segmentation strategy? - ..ANSWER...✓✓ Client-server
model
The IT department of a medium-sized enterprise is reviewing its
network architecture with a focus on increasing security and
efficiency. The organization currently uses a flat network model,
but the security team has proposed implementing Virtual Local
Area Networks (VLANs) to compartmentalize traffic and minimize
potential attack surfaces. The team's goal is to limit lateral
movement between network devices and enforce a principle of
least privilege across the network. Considering this security
improvement initiative, what is a major benefit of integrating
VLANs into the existing network architecture from a security
,2|Page
standpoint? - ..ANSWER...✓✓ Isolating network traffic and
reducing the potential attack surface
The network security engineer at a multinational company is
preparing to introduce a new network infrastructure model. The
company's objective is to minimize the attack surface by
implementing effective port security measures. To accomplish this,
the engineer is evaluating the security implications of various
architecture models and their compatibility with port security
measures. Since the network security engineer plans to deploy
port security to minimize the attack surface, which architecture
model can BEST assist in supporting and enhancing the
effectiveness of port security? - ..ANSWER...✓✓ Client-server
model
The network architect at a global financial institution is
overhauling the company's on-premises network to enhance
security and reduce the attack surface. To achieve this, the
architect assesses various architecture models and their impact on
the on-premises network's security implications. While
redesigning the on-premises network, which architecture model
would the network architect consider to decrease the attack
surface effectively? - ..ANSWER...✓✓ Client-server model
The chief information security officer (CISO) at a large enterprise
is implementing a new switching infrastructure. As part of this
process, the CISO wants to ensure the new infrastructure aligns
,3|Page
with the enterprise's existing security zones to maintain a strong
security posture. To provide effective security in the newly
implemented switching infrastructure while preserving security
zone integrity, which architecture model should the CISO employ?
- ..ANSWER...✓✓ Hierarchical model
A network architect at a large technology company designs a
new data center and has a mandate to minimize the potential
attack surface while ensuring the physical isolation of critical
systems. Given these requirements for a minimized attack surface
and physical isolation, which architectural model must the network
architect select? - ..ANSWER...✓✓ Hierarchical model
An organization's security officer is actively developing a new
data protection strategy. The plan aims to fortify the integrity of
data stored on the company's servers to uphold the
confidentiality, integrity, and availability (CIA) triad principles. In
this development process, which data protection method should
the security officer primarily implement to ensure the accuracy
and consistency of data over its entire life cycle, according to the
principles of the CIA triad, particularly focusing on enhancing the
"integrity" aspect? - ..ANSWER...✓✓ Checksum verification
The cybersecurity team at a multinational corporation suspects
that someone in the company is falsifying email communication
records to shift blame for missed deadlines. To ensure non-
repudiation, the cybersecurity team must implement a solution.
, 4|Page
What should the cybersecurity team implement to guarantee
non-repudiation in email communication, ensuring that the sender
cannot deny their emails' authenticity? - ..ANSWER...✓✓ Digital
signatures
A financial services company has hired a new cybersecurity team
to enhance its security posture. To improve data protection, the
team wants to implement an access control model that evaluates
the context and conditions of a user request access before
granting it. Which access control model should the cybersecurity
team implement to evaluate the context and conditions
surrounding a user's access request before granting permissions?
- ..ANSWER...✓✓ Attribute-based access control (ABAC)
The security team at a company is adopting a cybersecurity
framework to standardize its security measures across different
departments. The team lead wants to ensure that the selected
framework encompasses all the critical aspects of cybersecurity.
What should the security team lead confirm the cybersecurity
framework covers to provide a comprehensive security posture? -
..ANSWER...✓✓ It covers risk assessment, incident response,
access control, security awareness and training.
The security team at a financial services company is performing a
gap analysis to identify deficiencies in their existing security
posture. The team lead aims to understand where the
organization stands in terms of information security and where it
