QUESTION 1
In the context of modern telecommunications infrastructure, which of
the following best describes the primary function of a Session Border
Controller (SBC) within an enterprise IP telephony network?
A) To perform deep packet inspection for malware detection at the
application layer.
B) To interconnect disparate VoIP signaling protocols and manage
media streams for security and interoperability.
C) To serve as a primary DNS server for internal domain name
resolution.
D) To amplify Wi-Fi signals to extend wireless coverage in large office
environments.
Answer: B
Explanation: An SBC is a critical network element specifically designed
to control the signaling and media streams involved in setting up,
conducting, and tearing down VoIP calls. Its core functions include

protocol normalization between different vendors, NAT traversal,
topology hiding, and robust security policy enforcement, making option
B the most accurate. Option A describes an intrusion prevention system;
option C is a DNS function; and option D relates to wireless access
points.
QUESTION 2
A medium-sized enterprise is evaluating network architectures to
support its growing number of IoT devices. Which architectural model
offers the most scalable and secure framework for managing these
endpoints and their data?
A) A flat Layer 2 network with a single broadcast domain for all devices.
B) A hub-and-spoke VPN topology where all IoT traffic routes through a
central office.
C) A multi-tiered network employing segmentation, VLANs, and robust
firewall policies.
D) A peer-to-peer mesh network without centralized control.
Answer: C
Explanation: A multi-tiered design that implements network
segmentation (using VLANs or subnets) and stateful firewalls provides
the most scalable and secure environment for IoT. This approach limits
lateral movement in case of compromise, reduces broadcast traffic, and
allows for granular policy enforcement. Options A and D lack security
controls and scalability, while option B introduces a single point of
failure and potential latency bottlenecks.

QUESTION 3
What is the principal advantage of deploying Software-Defined Wide
Area Networking (SD-WAN) over traditional MPLS-based WAN
architectures for a multi-branch enterprise?
A) SD-WAN provides guaranteed bandwidth and lower latency than any
MPLS circuit.
B) SD-WAN allows for centralized, policy-based traffic steering across
multiple transport types, improving agility and reducing costs.
C) SD-WAN completely eliminates the need for any form of encryption
on the WAN.
D) SD-WAN is a hardware-only solution that simplifies physical
installation.
Answer: B
Explanation: SD-WAN decouples the networking hardware from its
control mechanism, enabling centralized management and dynamic
path selection. It allows enterprises to use a mix of broadband, LTE, and
MPLS, steering traffic based on application policies, which enhances
agility and often reduces operational expenses. Option A is incorrect
because MPLS can offer superior QoS guarantees; option C is false
because SD-WAN typically includes strong encryption; and option D is
wrong as SD-WAN is largely software-defined.

Which of the following cloud service models provides the consumer
with the capability to deploy onto the cloud infrastructure consumer-
created or acquired applications created using programming languages,
libraries, services, and tools supported by the provider, without
managing the underlying cloud infrastructure?
A) Infrastructure as a Service (IaaS)
B) Platform as a Service (PaaS)
C) Software as a Service (SaaS)
D) Function as a Service (FaaS)
Answer: B
Explanation: The description matches the NIST definition of Platform as
a Service (PaaS). In PaaS, the provider manages the underlying
infrastructure (servers, storage, networking, OS), while the consumer
controls the deployed applications and their configuration. IaaS
provides more control over the infrastructure, SaaS provides ready-to-
use software, and FaaS is a subset of serverless computing, not the
general description given.
QUESTION 5
In an enterprise security context, what does the principle of "least
privilege" specifically mandate for user access rights?
A) Users should be granted every permission they request to ensure
productivity.
B) Users should have administrative rights on their local machines to
install software.
