   A small remote site with 50 users currently uses a 3-tier design. The network team wants to simplify the design and reduce the number of devices while maintaining redundancy for the users. Which design change best meets these requirements?

   • AKeep the 3-tier design but use a single switch for each layer.
   • BReplace the access layer with a single switch and keep the distribution and core layers.
   • CMove all users to a cloud-based virtual network and eliminate the on-premises switches.
   • DReplace the distribution and core layers with a single pair of switches that perform both functions.

   A company is extending its on-premises data center to the cloud. They need a private, dedicated connection that provides consistent low latency and does not traverse the public internet. They also want to ensure that if the primary connection fails, traffic can still reach the cloud. Which combination of connectivity options should be used?

   • AUse a single VPN tunnel over the internet for simplicity and rely on the cloud provider's redundancy.
   • BUse two dedicated connections from the same provider to the same cloud region.
   • CUse a cloud provider's native internet gateway and rely on the cloud's anycast routing.
   • DUse a dedicated connection (such as AWS Direct Connect or Azure ExpressRoute) as the primary path and a VPN over the internet as a backup.

   A company is deploying a hybrid cloud architecture with latency-sensitive workloads. They have two on-premises data centers and need to connect to a single cloud provider. The design must provide high availability and low latency, and must avoid a single point of failure. Which connectivity design should be used?

   • AUse a single dedicated connection from one data center to the cloud provider.
   • BUse dedicated connections from each data center to the cloud provider, with VPN backups.
   • CUse a single VPN connection from each data center to the cloud provider.
   • DUse a dedicated connection from one data center and a VPN from the other, with the VPN as the primary path.

   A multinational company has offices in multiple regions and uses a public cloud for SaaS applications. They want to ensure that users in each office can reach the cloud with low latency, but they also want to minimize the cost of dedicated connections. They are considering using SD-WAN to connect offices to the cloud. Which design should they choose?

   • AUse a single dedicated connection from the headquarters to the cloud and route all traffic through it.
   • BUse SD-WAN with internet-based VPN tunnels to the cloud provider's nearest point of presence.
   • CUse a dedicated private connection from each office to the cloud provider.
   • DUse MPLS connections from each office to the cloud provider.
