What is a primary advantage of using a three-@er architecture for interconnec@ng buildings on a corporate campus? A) It requires fewer physical connec@ons due to a full mesh design between buildings. B) It enhances scalability by allowing easy addi@on of new buildings through a structured hierarchy. C) It reduces the need for high-end switches at the core layer by distribu@ng the load. D) It simplifies network management by collapsing the core and distribu@on layers into a single layer. Q2. What dis@nguishes Top-of-Rack (ToR) switches in a spine-leaf data center architecture? A) They directly connect to each other to form a mesh network. B) They serve as the primary rou@ng interfaces for external data center traffic. C) They act as leaves, connec@ng both to servers within the rack and spine switches. D) They exclusively manage the internal traffic within their respec@ve racks without interfacing with spine switches. Q3. You are a network administrator tasked with choosing a WAN technology that provides dedicated bandwidth and predictable latency for connec@ng two sites. However, high bandwidth is not a requirement. Given the need for these specific characteris@cs, which WAN technology would be the most appropriate choice? A) VPN over the Internet B) Frame Relay C) Asynchronous Transfer Mode (ATM) D) Point-to-Point connec@on using PPP © 2024 Kevin Wallace Training, LLC Q4. You are seYng up a network for a small office with a mix of wired and wireless devices, including laptops, smartphones, and a server. To ensure all devices can communicate internally and access the Internet, which combina@on of network devices is most appropriate for your SOHO environment? A) A wireless router with built-in Ethernet ports, connected to an external cable modem B) A cable modem and a standalone Ethernet switch without wireless capabili@es C) Mul@ple wireless access points to form a mesh network without a router D) A dedicated firewall device without integrated rou@ng or switching capabili@es Q5. As the IT director of a growing enterprise, you're strategizing on how to scale your compu@ng resources efficiently while maintaining control over cri@cal data. Given the desire to combine the flexibility of cloud resources with the security of in-house systems, which cloud deployment model would best fit your objec@ves?

What is a primary advantage of using a three-@er architecture for interconnec@ng buildings on a corporate campus? A) It requires fewer physical connec@ons due to a full mesh design between buildings. B) It enhances scalability by allowing easy addi@on of new buildings through a structured hierarchy. C) It reduces the need for high-end switches at the core layer by distribu@ng the load. D) It simplifies network management by collapsing the core and distribu@on layers into a single layer. Answer: B) It enhances scalability by allowing easy addi@on of new buildings through a structured hierarchy. Explana5on: The three-@er architecture (access, distribu@on, and core layers) provides a scalable way to interconnect buildings on a corporate or university campus. By structuring the network into @ers, new buildings can be added by simply replica@ng the exis@ng structure and connec@ng the building's distribu@on layer to the core layer. This structured approach avoids the scalability issues of a full mesh architecture, where each building would need to connect to every other building, significantly increasing the complexity and number of physical connec@ons required. Q2. What dis@nguishes Top-of-Rack (ToR) switches in a spine-leaf data center architecture? A) They directly connect to each other to form a mesh network. B) They serve as the primary rou@ng interfaces for external data center traffic. C) They act as leaves, connec@ng both to servers within the rack and spine switches. D) They exclusively manage the internal traffic within their respec@ve racks without interfacing with spine switches. Answer: C) They act as leaves, connec@ng both to servers within the rack and spine switches. Explana5on: In a spine-leaf architecture, Top-of-Rack (ToR) switches play a pivotal role as "leaves" by interfacing with both the servers (and other devices like firewalls, load balancers, routers, etc.) located within their specific rack and the spine switches that form the backbone of the data center's network. This dual responsibility ensures high availability through redundancy and facilitates efficient data flow across the data center, dis@nguishing them from switches that might only manage internal rack traffic or connect racks without interfacing with a centralized backbone. © 2024 Kevin Wallace Training, LLC Q3. You are a network administrator tasked with choosing a WAN technology that provides dedicated bandwidth and predictable latency for connec@ng two sites. However, high bandwidth is not a requirement. Given the need for these specific characteris@cs, which WAN technology would be the most appropriate choice? A) VPN over the Internet B) Frame Relay C) Asynchronous Transfer Mode (ATM) D) Point-to-Point connec@on using PPP Answer: D) Point-to-Point connec@on using PPP Explana5on: A point-to-point connec@on using the Point-to-Point Protocol (PPP) is the most suitable choice for dedicated bandwidth and predictable latency between two sites. This is because a point-to-point connec@on is exclusively reserved for use between these two sites, ensuring that the bandwidth is not shared with others and that the latency remains consistent. Unlike Frame Relay, ATM, or VPNs over the Internet, a point-to-point connec@on does not involve traffic from other clients on the network, which could otherwise introduce variability in bandwidth and latency. Q4. You are seYng up a network for a small office with a mix of wired and wireless devices, including laptops, smartphones, and a server. To ensure all devices can communicate internally and access the Internet, which combina@on of network devices is most appropriate for your SOHO environment? A) A wireless router with built-in Ethernet ports, connected to an external cable modem B) A cable modem and a standalone Ethernet switch without wireless capabili@es C) Mul@ple wireless access points to form a mesh network without a router D) A dedicated firewall device without integrated rou@ng or switching capabili@es Answer: A) A wireless router with built-in Ethernet ports, connected to an external cable modem Explana5on: For a small office/home office (SOHO) environment that includes both wired and wireless devices, a wireless router with built-in Ethernet ports connected to an external cable modem (or other broadband technology) is the most suitable setup. This configura@on allows wired devices to connect through Ethernet ports and wireless devices to connect via Wi-Fi, ensuring all devices can communicate with each other and access the Internet. Unlike the other op@ons, this setup provides a comprehensive solu@on for both internal networking and Internet connec@vity, leveraging the versa@lity of a wireless router with Ethernet capabili@es. © 2024 Kevin Wallace Training, LLC Q5. As the IT director of a growing enterprise, you're strategizing on how to scale your compu@ng resources efficiently while maintaining control over cri@cal data. Given the desire to combine the flexibility of cloud resources with the security of in-house systems, which cloud deployment model would best fit your objec@ves? A) Public Cloud B) Private Cloud C) Hybrid Cloud D) Community Cloud Answer: C) Hybrid Cloud Explana5on: The Hybrid Cloud model is the op@mal choice for organiza@ons looking to blend the scalability and elas@city of cloud services with the security and control of an on-premises infrastructure. This model allows for cri@cal data and applica@ons to be managed on-premises (private cloud) for security and compliance, while also leveraging the cloud (public cloud) for scalable, on-demand resources. This approach provides a balanced solu@on that can adapt to fluctua@ng demands and offers a phased migra@on pathway to the cloud. © 2024 Kevin Wallace Training, LLC
