Part 1.8

Which of the following best describes a primary benefit of implementing Software-Defined Networking (SDN) in a modern network environment?

• It eliminates the need for any physical network hardware.

• It allows centralized management and automation of network resources.

• It increases network latency by adding more control layers.

• It restricts network scalability to small environments.

When deploying SD-WAN, which strategy helps optimize application performance across multiple branch locations?

• Using a single static route for all traffic

• Dynamically selecting the best available WAN link based on real-time conditions

• Disabling all security features to reduce overhead

• Relying solely on MPLS circuits

How does VXLAN address the limitations of traditional VLANs in large-scale data centers?

• By reducing the number of available VLAN IDs

• By supporting up to 16 million logical networks over a shared infrastructure

• By eliminating the need for any encapsulation

• By restricting network segmentation

Which principle is central to Zero Trust Architecture (ZTA)?

• Trusting all devices inside the corporate network

• Never trust, always verify, regardless of network location

• Allowing unrestricted access to internal resources

• Using only perimeter-based security

Which of the following is a core component of Secure Access Service Edge (SASE)?

• Physical firewalls only

• Cloud-delivered security services integrated with wide area networking

• Manual configuration of all network devices

• On-premises-only access control

In SD-WAN environments, which approach enhances network security for remote branches?

• Disabling encryption to improve speed

• Integrating security policies and traffic inspection at the edge

• Allowing all traffic without inspection

• Using only a single ISP connection

How does Infrastructure as Code (IaC) improve network management?

• By requiring manual configuration of each device

• By enabling automated, repeatable deployment of network resources using code

• By limiting network changes to once per year

• By removing the need for version control

Which deployment method would best utilize SD-WAN to support a company with multiple cloud applications and remote users?

• Directing all traffic through a central data center

• Enabling local internet breakout at branch sites for cloud access

• Forcing all users to use VPN tunnels to headquarters

• Disabling dynamic path selection

What is a key use case for implementing VXLAN in a data center?

• Limiting the number of virtual machines per network

• Extending Layer 2 networks across geographically dispersed locations

• Preventing any network segmentation

• Reducing the number of available IP addresses

Which action aligns with the Zero Trust principle of “least privilege”?

• Granting all users administrator access by default

• Providing users only the minimum access necessary to perform their job functions

• Allowing unrestricted access to all network resources

• Disabling all authentication requirements
