Which Cisco switch series is designed to handle the combined responsibilities of core and distribution layers in a converged architecture?
Answer : D
The Cisco Catalyst 9000 Series is engineered to address the evolving needs of modern enterprise networks by integrating the functionalities of both the core and distribution layers into a unified, converged architecture. This series offers advanced capabilities such as high-speed data forwarding, enhanced security features, and support for automation and programmability, making it suitable for scalable and efficient network designs.
The Catalyst 9000 Series includes models like the Catalyst 9500 and 9600, which are optimized for core and distribution roles, providing high throughput and reliability. These switches support advanced features like Software-Defined Access (SD-Access) and are designed to meet the demands of cloud-scale and security-focused environments.
In contrast, the Meraki MS400 Series (Option A) is tailored for cloud-managed aggregation and lacks the comprehensive feature set required for core functionalities. The Catalyst 6500 E-Series (Option B), while historically significant, is considered a legacy platform and may not support the latest advancements in network convergence. The Catalyst 1300 Series (Option C) is designed for small to medium-sized businesses and is not intended for core or distribution layer deployments.
What is the primary purpose of backing up the endpoint configuration prior to replacing the device?
Answer : D
Backing up the configuration of a network device before replacement is a critical step to ensure business continuity and minimize downtime. The primary purpose of this backup is to restore the existing settings onto the new device, ensuring that it operates identically to the one being replaced.
This process includes preserving interface configurations, routing protocols, access control lists, and other essential parameters. By restoring the backed-up configuration to the new device, network administrators can quickly reintegrate it into the network infrastructure without the need for manual reconfiguration, thereby reducing the risk of errors and service disruptions.
Options A, B, and C do not align with the primary objective of configuration backups in the context of device replacement.
Which action must be taken before powering down the endpoint during the replacement process of a Cisco collaboration device?
Answer : B
Before shutting down any Cisco collaboration device (such as an IP phone, video endpoint, or codec) for replacement, it is essential to back up the configuration. This ensures that all custom settings, including user profiles, network configurations, and service settings, are preserved and can be quickly restored on the replacement device.
This backup minimizes downtime and avoids manual reconfiguration errors during the swap process.
Which component serves as the central management and communication core and provides a single point of management via Cisco UCS Manager in a Cisco UCS environment?
Answer : D
The UCS Fabric Interconnect is the central management and communication hub of the Cisco UCS (Unified Computing System) environment. It integrates compute, network, and storage access into a unified system.
Fabric Interconnects:
Manage all servers and I/O modules connected to the UCS domain
Provide connectivity and are the point of integration with the Cisco UCS Manager
Offer high-availability and centralized policy management
Other options like the Nexus or MDS switches do not serve this unified management function in a UCS deployment.
The UCS Fabric interconnect serves as the central management and communication core in a Cisco UCS environment, providing a single point of management via Cisco UCS Manager for the entire UCS system, including servers, networking, and storage components.
What is the primary advantage of installing and deploying Cisco UCS E-Series servers in branch office routers?
Answer : C
Cisco UCS E-Series servers are integrated, blade-style compute modules that can be installed inside Cisco ISR (Integrated Services Routers). Their primary advantage is to provide local compute resources in branch offices without needing a full data center environment.
This enables:
Hosting of virtual machines or applications locally
Reduced latency for edge computing
Lowered dependency on central data center resources
These servers are ideal for running branch-office workloads, virtualization, or edge analytics, allowing enterprises to deploy scalable compute capabilities closer to the data source.
What is the recommended resistance value range to ensure proper grounding when using an antistatic strap to perform work on electrical components?
Answer : B
The ideal resistance range for ESD wrist straps is between 1 and 10 megaohms. This range is sufficient to safely discharge static electricity from the technician to ground, while not allowing an abrupt discharge that could damage sensitive electronic components.
Values below 1 megaohm may result in a rapid discharge, risking damage.
Values above 10 megaohms may not discharge static efficiently enough.
Which two results are achieved by briefly pressing the restore/reset button on a Cisco Meraki switch? (Choose two.)
Answer : A, D
On a Cisco Meraki switch, briefly pressing the restore/reset button (typically less than 5 seconds) triggers:
A reboot of the device (Option A)
Clearing of the local management interface settings (Option D), which may include temporary network information such as DHCP leases or local overrides.
To perform a full factory reset (Option B), the button must be held down for a longer duration, usually more than 10 seconds. Options C and E do not reflect standard reset behavior.
