A logistics company has 30 distribution centers. Each center has a primary MPLS circuit and a backup broadband circuit. The company wants to ensure that if the MPLS circuit fails, traffic automatically moves to the broadband circuit. However, the broadband circuit is only 50% of the MPLS bandwidth. Which design approach best handles the bandwidth difference during failover?

Configure the broadband link to carry all traffic during failover

Use the broadband link only for internet traffic and keep MPLS for all other traffic

Increase the MPLS bandwidth to match the broadband link

Use SD-WAN to dynamically route only critical applications over the broadband link during failover

Which WAN link type is a dedicated, point-to-point circuit that provides guaranteed bandwidth and is often used for critical connections?

Dedicated circuit (e.g., T1/E1, Ethernet private line)

A government agency is deploying SD-WAN to connect 100 field offices. The agency requires that all traffic be encrypted, but also needs to inspect traffic for malware. The current SD-WAN solution supports IPsec encryption but not deep packet inspection (DPI). What is the best approach to meet both requirements?

Disable encryption to allow the SD-WAN to inspect traffic

Deploy a separate security appliance at each site to inspect traffic after decryption

Use the SD-WAN's built-in DPI and accept the lack of encryption

Route all traffic to a central location for inspection

A retail chain with 200 small stores needs to connect each store to headquarters. The stores require access to a cloud-based inventory system and occasionally transfer large batch files. The company wants to minimize per-site cost while maintaining the ability to encrypt traffic and support dynamic path selection. Which WAN connectivity approach best meets these requirements?

A site-to-site IPsec VPN over a single DSL line per store

An SD-WAN solution over broadband internet connections

A dedicated MPLS circuit to each store

A private dedicated circuit from each store to the cloud provider

A company is provisioning a new 50-employee branch office. The branch runs a real-time VoIP service that requires 100 kbps per call with up to 20 concurrent calls, and a business application that averages 150 Mbps during peak hours. The design must ensure voice quality is not degraded by data traffic. What is the minimum WAN link capacity that should be ordered?

200 Mbps with QoS marking voice as high priority

100 Mbps with QoS marking voice as high priority
