NEW QUESTION # 42 
Refer to the exhibit. Drag and drop the functions from the left onto the corresponding internal memory components on the right.
Answer:
Explanation:
Explanation:
NVRAM # Startup configuration
RAM # Running configuration
ROM # Bootstrap code, POST code, ROM monitor
Flash memory # Cisco IOS software, backup configuration
Each memory type in a Cisco device serves a specific function in the boot process and runtime operation.
NVRAM retains configuration across reboots, RAM is volatile and holds active configs, ROM handles initial boot tasks, and flash stores the operating system.
This content is covered thoroughly in"Cisco Equipment and Related Hardware"in the FLDTEC curriculum. Here's the breakdown:
ROM (Read-Only Memory)
* Stores bootstrap code, POST (Power-On Self-Test), and ROM Monitor.
* These are essential for the device's initial power-on operations and recovery modes.
NVRAM (Non-Volatile RAM)
* Holds thestartup configuration file, which is loaded during the boot process.
* Content remains intact after a reboot or power cycle.
RAM (Random Access Memory)
* Stores therunning configurationand current operational state of the router or switch.
* Also used for routing tables, ARPcache, and packet buffers.
* Data is lost when the device is powered off or rebooted.
Flash Memory
* Contains theCisco IOS image, system files, and can storebackup configurations.
* It is a non-volatile storage, so it retains data after reboots.
NEW QUESTION # 43
Drag and drop the steps of the boot sequence process of a Cisco device into order on the right.
Answer:
Explanation:
Explanation:
Step 1 # Performs power-on self-test (POST)
Step 2 # Loads and runs bootstrap code (firmware)
Step 3 # Finds and loads the Cisco IOS software
Step 4 # Finds and loads the configuration
Step 5 # Runs the configured Cisco IOS software
This startup process is thoroughly described in theFLDTECcourse and alignswith Cisco's standard IOS boot process:
* POST (Power-On Self-Test):Verifies hardware functionality including memory and interfaces. This occurs immediately upon powering the device.
* Bootstrap Code Execution:Bootstrap is a small program in ROM that initiates the boot process.
* Cisco IOS Loading:Bootstrap locates and loads the IOS from flash memory or another source (e.g., TFTP).
* Configuration Loading:The router then loads the startup-config from NVRAM (if available).
* IOS Execution:Once the configuration is loaded, the device enters operational mode and executes the IOS with the loaded config.
This sequence is vital for field technicians to understand for troubleshooting boot failures or performing device recoveries.
NEW QUESTION # 44
Which action must be taken when editing a captured configuration of an old device for reuse in a replacement device?
- A. Remove all configurations under line vty 0 4.
- B. Retain all username entries.
- C. Add the enable password cisco command.
- D. Keep all access-listcommands intact.
Answer: B
Explanation:
Within theFLDTECtraining, especially underMaintenance and RMA Procedures, there is a strong emphasis on safely transferring and adapting configurations from failed or decommissioned devices to replacement units.
The official guidance includes the following:
"When reusing a configuration from an old device, make sure to retain the necessary security elements such as username entries. This ensures the replacement device is still accessible under the correct user credentials." Here's a breakdown of why the correct answer isB:
* A. Remove all configurations under line vty 0 4:This would eliminate remote access settings, making it harder to manage the device.
* B. Retain all username entries:Correct. Keeping the username entries ensures continued secure access and avoids loss of administrative control.
* C. Keep all access-list commands intact:Not always required - ACLs are often tailored to interface- specific settings or environments which may differ between devices.
* D. Add the enable password cisco command:Not a best practice. Default passwords (like cisco) should be avoided for security reasons, and it's not required if enable secret is already in use.
NEW QUESTION # 45
What is the function of an access layer device?
- A. Connects remote offices to the main corporate network
- B. Provides high-speed data transport between buildings or different parts of the campus
- C. Serves as the entry point for end-user devices to connect to the network
- D. Provides secure external access to internal network components
Answer: C
Explanation:
In the hierarchical network design model, the access layer is the first layer and serves as the entry point for end-user devices to connect to the network. This layer connects user devices such as PCs, IP phones, wireless access points, printers, and scanners to the network. It facilitates the initial connection between end-user devices and the network infrastructure. The access layer also enforces security policies and provides services such as VLAN membership, port security, and Quality of Service (QoS).
Options A, C, and D refer to functions typically associated with the core or distribution layers, or with WAN connectivity, rather than the access layer.
NEW QUESTION # 46
Which protocol should be analyzed when troubleshooting call quality between IP phones?
- A. 323: An older protocol suite for multimedia communication, encompassing both signaling and media, but less commonly used in modern IP telephony. Reference: Supporting Cisco Devices for Field Technicians (FLDTEC) - Troubleshooting Methodologie
- B. H.323
- C. SIP
- D. RTP
- E. SCCP
Answer: D
Explanation:
When addressing call quality issues between IP phones, the Real-time Transport Protocol (RTP) is the primary protocol to analyze. RTP is responsible for the actual transmission of voice data during a call, and its performance directly impacts call quality.
Key factors affecting RTP and, consequently, call quality include:
Packet Loss: Missing packets can lead to audio gaps.
Jitter: Variations in packet arrival times can cause choppy audio.
Latency: Delays in packet delivery can result in noticeable lag.
Analyzing RTP streams allows technicians to identify these issues and implement appropriate Quality of Service (QoS) measures to mitigate them.
In contrast:
SIP (Session Initiation Protocol): Handles call setup, modification, and teardown but not the media stream.
SCCP (Skinny Client Control Protocol): A Cisco proprietary protocol for signaling, not media transport.
NEW QUESTION # 47
What happens to the switch operation when a supervisor module in a Cisco Nexus switch is replaced by two supervisor modules?
- A. Only the affected line cards reset.
- B. All modules in the switch are reset due to a stateless switchover.
- C. The switch shuts down completely.
- D. The switch continues to operate without any interruption.
Answer: B
Explanation:
In Cisco Nexus switches, when transitioning from a single supervisor module to a dual supervisor configuration, the behavior depends on the redundancy mode configured.
Stateful Switchover (SSO): In configurations supporting SSO, the active and standby supervisors synchronize their state and configuration, allowing for seamless failover without resetting other modules.
Stateless Switchover (Warm Standby): In certain modes, such as the ACI-mode on Cisco Nexus 9508 switches, the standby supervisor does not maintain synchronized state information with the active supervisor. In this scenario, if a switchover occurs (e.g., due to the replacement of the active supervisor), all modules in the switch are reset because the switchover is stateless.
Therefore, when a supervisor module is replaced in a configuration that does not support stateful switchover, all modules in the switch are reset due to the stateless nature of the switchover.

- A. Supporting meeting experiences
- B. Network bandwidthallocation
- C. Phone book administration
- D. Facilitating connections
- E. Hosting large-scale databases
Answer: A,D
Explanation:
The Cisco Collaboration Infrastructure is designed to support unified communications, video conferencing, and team collaboration through an integrated architecture involving both hardware (e.g., endpoints, media servers) and software (e.g., CUCM, Webex apps).
According to the FLDTEC course content under Cisco Collaboration Equipment and Infrastructure:
Facilitating Connections (C):
Cisco infrastructure components such as CUCM, Expressway, and Cisco Meeting Server enable real-time connections between users across voice, video, and messaging systems.
Supporting Meeting Experiences (E):
Devices such asWebex Boards, Room Kits, and Cisco Quad Cameras, in combination with platforms like Webex, provide immersive and seamless meeting experiences, supported by the infrastructure.
Incorrect Options:
A:Network bandwidth allocation: Typically managed by network QoS policies and WAN optimizations, not the collaboration infrastructure directly.
B:Hosting large-scale databases: Not a function of Cisco's collaboration system - this falls under data center or database server roles.
D:Phone book administration: Often a function within directory services or external LDAP integration, not a core collaboration infrastructure task.
NEW QUESTION # 50
Refer to the exhibit.
Refer to the exhibit. What is the redundancy implementation in this Cisco UCS architecture?
- A. Redundancy is achieved through dual fabric interconnects, providing separate paths for FCoE, FC, and LAN traffic.
- B. Redundancy is limited to the uplink connections, with no failover capabilities between the fabric interconnects.
- C. The system uses a single point of connectivity, relying on internal redundancy within each UCS chassis.
- D. Redundancy is implemented at the chassis level only, with chassis 1 acting as a backup for chassis 2.
Answer: A
Explanation:
In the provided Cisco UCS architecture diagram, the infrastructure consists of:
Two Fabric Interconnects (A and B), each connecting to:
Ethernet (LAN)
Fibre Channel (FC)
FCoE (Fibre Channel over Ethernet)
Both Fabric Interconnects are independently connected to both Cisco UCS Chassis 1 and 2 through I/O Modules (IOMs).
This is the classic active-active UCS design, providing full path redundancy for all traffic types:
LAN uplinks are handled separately by Fabric Interconnect B.
SAN traffic is distributed through FC uplinks and FCoE uplinks via Fabric Interconnects A and B.
Each server in the chassis can fail over its traffic to the alternate fabric if one interconnect fails.
This architecture guarantees no single point of failure, which is essential in mission-critical environments like data centers and enterprise server farms.
NEW QUESTION # 51
Which command is used to determine if there is sufficient space in the memory of a device before installing a new Cisco IOS image?
- A. show file-system
- B. show flash:
- C. show memory
- D. show storage
Answer: B
Explanation:
Theshow flash:command is used todisplay the contents of the device's flash memory, which is where the Cisco IOS image is typically stored. By issuing this command, a technician can verify available space and determine whether there is enough capacity to accommodate a new IOS image before initiating an upgrade or image replacement process.
This command provides a detailed listing of files, their sizes, and the total and available memory space within the flash file system.
* show file-systemlists all available file systems but doesn't detail their content.
* show memoryshows runtime memory usage (RAM), not flash memory.
* show storageis not a standard IOS command.

NEW QUESTION # 52
Which two actions are typically performed in ROMMON mode during the password recoveryprocess?
(Choose two.)
- A. Load the startup configuration.
- B. Change the configuration register.
- C. Reboot the device.
- D. Modify passwords.
- E. Save the configuration.
Answer: B,C
Explanation:
During the password recovery process on Cisco devices, ROMMON (ROM Monitor) mode is utilized to perform specific actions that facilitate the recovery. Two critical actions typically performed in ROMMON mode are:
* Change the Configuration Register:The configuration register is modified to instruct the device to ignore the startup configuration during the next boot. This is commonly achieved by setting the configuration register to0x2142. This action prevents the device from loading the saved configuration, allowing access without requiring the existing passwords.
* Reboot the Device:After changing the configuration register, the device is rebooted to apply the new settings. This reboot enables the device to bypass the startup configuration, facilitating the password recovery process.
These steps are essential in the password recovery procedure, allowing administrators to regain access to the device without erasing the existing configuration.
