Key details for this exam, checked against the published exam outline
Each question shows the correct answer and an explanation of why it is right
Which hardware platform is Cisco Unified Communications Manager typically deployed on?
Cisco Unified Communications Manager (CUCM) is typically deployed on Cisco UCS C-Series servers. These rack-mount servers provide the necessary computing resources to support CUCM's call control and session management functions in enterprise environments. The UCS C-Series servers offer scalability, reliability, and integration capabilities essential for unified communications deployments.
Options A (Cisco ASR routers), B (Cisco Catalyst switches), and C (Cisco ISR routers) are networking devices designed for routing and switching functions and are not intended as platforms for deploying CUCM.
Which Cisco switch series is designed to handle the combined responsibilities of core and distribution layers in a converged architecture?
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 are two indicators that a network interface card must be replaced? (Choose two.)
A Network Interface Card (NIC) is essential for device connectivity. Two common symptoms indicating that a NIC may be faulty and require replacement are:
Connectivity problems (Option A): Devices may fail to communicate with the network, showing no IP address assignment or inability to ping/connect to other devices.
Consistent link down status (Option D): The link LED may stay off or frequently go down, even when connected to a functioning switch port with a known-good cable.
Other options like configuration issues (Option B) or system crashes (Option E) might be due to software or unrelated hardware components, and boot failures (Option C) typically point to motherboard or storage faults.
Which Cisco collaboration component is an enterprise-grade, cloud-based PBX system that enables devices to register to the cloud?
Cisco Webex Calling is a cloud-based, enterprise-grade PBX (Private Branch Exchange) solution designed to provide comprehensive voice communication services via the Webex cloud platform. It enables IP phones and softphones to register to the cloud, allowing for centralized call control, voicemail, and collaboration features without the need for an on-premises call manager.
Cisco Hosted Collaboration Solutions are partner-hosted services.
Webex Meetings supports virtual video conferencing.
Webex Teams (now part of Webex App) supports messaging and collaboration, not PBX functionality.
Which deployment scenarios are Cisco 8000 Series routers primarily designed for?
Cisco 8000 Series routers are primarily designed for service provider and web-scale networks, offering high-performance routing capabilities to handle large-scale, high-bandwidth environments typically found in service provider infrastructures and data centers.
The Cisco 8000 Series routers are part of Cisco's high-performance routing portfolio. As documented in the official Cisco product and FLDTEC study materials:
Cisco 8000 Series routers are purpose-built for service provider and cloud-scale data centers.
They are designed to support massive bandwidth, 5G core, and edge routing demands.
These routers provide scalable, high-performance architecture, using Cisco Silicon One ASICs, enabling terabits of throughput with advanced telemetry and network programmability.
Why the other options are incorrect:
A . Remote branches and retail typically use ISR/ASR 1000/1100 Series.
C . Home or small business networks use Cisco RV Series or Meraki MX Series.
D . LAN access/distribution layers in campuses commonly use Catalyst 9000 Series switches or ISR routers, not high-end core routers.
The 8000 Series is typically found in service provider core, data center interconnect, and hyperscale cloud deployments (e.g., Google, Meta, AWS).
Which key sequence is used to enter the boot prompt mode when the Cisco NX-OS Software begins the software boot process?
During the boot process of Cisco devices running NX-OS, pressing Ctrl-C at the right time will interrupt the boot sequence and bring the system to the boot loader or ROMmon mode (commonly referred to as the boot prompt).
This allows a technician to perform low-level operations such as recovering passwords, specifying an alternate boot image, or performing diagnostics.
Other options (Ctrl-X, Ctrl-Z, Ctrl-1) are not used for interrupting the boot process in Cisco NX-OS platforms.
A technician must quickly identify multiple Cisco switches in a rack without powering them on. Where should the technician look for serial numbers on the device?
The serial number for Cisco switches is typically found on a label located on the rear panel near the power supplies. This positioning allows technicians to quickly access identification information even when the device is not powered on.
This label is essential for inventory tracking, RMA procedures, and registration for support. Serial numbers are not typically placed on the top or bottom surfaces for devices mounted in a rack, as those areas are less accessible.
