Explanation:
A routing table in a Cisco Nexus switch is used to store information about network routes. Its primary purpose is to keep track of IP addresses and determine the best path for forwarding data packets across the network. This ensures efficient and effective data transmission. Storing MAC addresses for forwarding decisions is a function of the MAC address table, not the routing table. Managing VLAN configurations is related to VLAN management, and monitoring network traffic is typically handled by network monitoring tools.

Explanation:
The correct command to assign a name to a VLAN on a Cisco Nexus switch is vlan 10 name Accounting. This command creates VLAN 10 and assigns it the name “Accounting”. The other options do not correctly combine the necessary elements of the command or are syntactically incorrect. The switchport mode access command is used to assign a VLAN to a switch port, not to name a VLAN.

Explanation:
The first step Jessica should take is to check the interface logs and error messages. This diagnostic procedure will help her identify the specific nature of the problem causing the high error rates. Replacing cables, restarting the switch, or upgrading the firmware may be necessary later, but understanding the specific issue through logs and error messages is crucial for targeted troubleshooting. This approach follows standard diagnostic procedures and ensures that the root cause is accurately identified before taking corrective actions.

Explanation:
Cisco UCS integrates computing, networking, and storage resources into a cohesive system, which simplifies management and enhances scalability. This unified approach reduces complexity and makes it easier to deploy and manage resources compared to traditional data center architectures. Reduced power consumption, increased physical security, and enhanced Wi-Fi coverage are not primary benefits of UCS.

Explanation:
IEEE 802.1Q is the standard VLAN trunking protocol used to carry traffic for multiple VLANs across a single physical link. It inserts a VLAN tag into the Ethernet frame to identify the VLAN to which the frame belongs. STP (Spanning Tree Protocol) prevents network loops, VTP (VLAN Trunking Protocol) manages VLAN configurations across switches, and MPLS (Multiprotocol Label Switching) is used for high-performance telecommunications networks.

Explanation:
Proper cooling and airflow management are critical for maintaining optimal operating temperatures and preventing overheating in data centers. Ensuring all racks are of the same height and using only copper cabling are not primary environmental considerations. Installing as many servers as possible in each rack without considering cooling can lead to overheating and equipment failure.

Explanation:
Distributing the weight evenly across the rack ensures stability and prevents the rack from tipping over. Placing the heaviest equipment at the top can cause the rack to become top-heavy and unstable. Installing equipment quickly without considering weight distribution can compromise safety. Using multiple power sources can provide redundancy and prevent a single point of failure.

Explanation:
Cisco ACI is a software-defined networking (SDN) solution that simplifies network management and automation. It uses application policies to define network behavior, making it easier to deploy, manage, and scale data center networks. Enhancing Wi-Fi signal strength, providing advanced firewall capabilities, and increasing the number of available IP addresses are not primary functions of Cisco ACI.

Explanation:
Dual power supplies with separate circuits provide power redundancy, ensuring continuous operation even if one power source fails. This setup reduces the risk of downtime due to power issues. Single power supplies do not offer redundancy, battery-operated power supplies are not typically used in this context, and power supplies with built-in UPS provide backup power but are not a common redundancy strategy in data centers.

Explanation:
The primary purpose of STP is to prevent network loops, which can cause broadcast storms and disrupt network communication. STP achieves this by creating a loop-free logical topology, even in networks with redundant paths. Segmenting the network into smaller broadcast domains is done using VLANs, IP address assignment is handled by DHCP, and encrypting data traffic is achieved through protocols like IPsec.

Explanation:
Regular maintenance procedures include periodically checking and updating the firmware and software to ensure devices operate with the latest features and security patches. Performing a complete factory reset is not part of routine maintenance and can lead to data loss. Disabling unused ports and replacing hardware components should be based on specific needs, not regular intervals.

Explanation:
The common first step in troubleshooting network connectivity issues is to check the physical connections and interface status. This helps identify if there are any disconnected cables or down interfaces. Replacing the switch, resetting configurations, or upgrading firmware are more drastic measures that should be considered only after basic troubleshooting steps are exhausted.

Explanation:
Cisco Nexus switches support Fibre Channel over Ethernet (FCoE), which allows storage and data traffic to be consolidated onto a single network. This enhances data center performance by reducing the need for separate storage networks and improving efficiency. Integrated Wi-Fi capabilities, built-in antivirus software, and desktop virtualization support are not primary features of Cisco Nexus switches.

Explanation:

It provides high-speed data transfer and centralized storage management, which is critical for data centers. Providing network connectivity for wireless devices, enabling secure remote access, and enhancing video conferencing capabilities are not the primary functions of a SAN.

Explanation:
Cisco’s Technical Assistance Center (TAC) provides expert advice and support for troubleshooting and resolving network issues. TAC engineers assist with diagnosing problems, recommending solutions, and providing technical guidance. On-site hardware replacement, installing and configuring new network devices, and performing regular maintenance checks are not primary functions of TAC.

Explanation:
Reviewing device logs and error messages is essential for identifying and diagnosing specific issues affecting the device. These logs provide detailed information about the events and errors encountered by the device, which can help in pinpointing the root cause of the problem. Resetting the device, automatically fixing errors, and preventing unauthorized access are not direct outcomes of reviewing logs.

Explanation:
Regularly updating the firmware and software on Cisco data center devices is important to add new features, improve performance, and address security vulnerabilities. Firmware and software updates ensure that devices operate efficiently and are protected against known threats. Ensuring backward compatibility, increasing physical security, and reducing the need for network monitoring are not primary reasons for regular updates.

Explanation:
In a Cisco UCS environment, a Service Profile is used to define the configuration of a server, including its hardware and software settings. This allows for consistent and automated deployment of server configurations, simplifying management and reducing the potential for errors. Managing Wi-Fi settings, configuring network switches, and creating virtual machines are not functions of a Service Profile.

Explanation:
Proper grounding and bonding are critical for ensuring electrical safety and preventing equipment damage in a data center. This reduces the risk of electrical faults, protects personnel, and helps maintain the reliability and longevity of the equipment. Enhancing aesthetic appearance, preventing unauthorized access, and increasing network bandwidth are not related to grounding and bonding.

Explanation:
Cisco MDS switches are primarily used to manage and optimize storage networks in data centers. They offer high-performance, scalable, and reliable connectivity for storage devices, ensuring efficient data transfer and storage management. Providing high-speed Ethernet connectivity, supporting Wi-Fi connections, and enabling remote desktop access are not the primary functions of Cisco MDS switches.

Explanation:
The show ip route command is used to display the routing table on a Cisco Nexus switch. This command provides information about the routes known to the switch and how packets are forwarded. The show interfaces command displays interface information, show vlan displays VLAN configurations, and show mac address-table displays the MAC address table.

Explanation:
A spine-leaf architecture improves scalability and reduces latency by providing a consistent, low-latency path between any two points in the data center. This architecture consists of spine switches that connect to leaf switches, ensuring efficient traffic flow and minimizing congestion. Simplified wireless network management, enhanced physical security, and increased power efficiency are not direct benefits of this architecture.

Explanation:
vPC (Virtual Port Channel) is a feature of Cisco Nexus switches that allows for high availability and fast failover. It enables the creation of a single logical port channel across two physical switches, providing redundancy and ensuring that traffic continues to flow even if one switch fails. VLAN Trunking, QoS, and NAT are important features but do not specifically address high availability and fast failover in the same way as vPC.

Explanation:
RSTP (Rapid Spanning Tree Protocol) provides faster convergence than the original STP and is commonly used in Cisco networks to reduce the time it takes for a network to recover from topology changes. PVST and MSTP offer per-VLAN and multiple spanning tree instances, respectively, but RSTP is specifically designed for rapid convergence. STP is the original version and converges more slowly than RSTP.

Explanation:
FCoE (Fibre Channel over Ethernet) is a protocol used to connect storage devices over an Ethernet network in a data center. It allows Fibre Channel frames to be encapsulated and transmitted over Ethernet networks, consolidating storage and data traffic onto a single network. IPsec is used for secure IP communications, SNMP for network management, and OSPF for routing.

Explanation:
Cisco Packet Tracer is a network simulation tool that allows users to simulate network topologies and configurations. It is widely used for educational purposes and to test network designs before deploying them in a production environment. Cisco Prime and Cisco DNA Center are network management tools, while Cisco AnyConnect is a VPN client.

Explanation:
Using identical hardware components ensures compatibility and reduces the risk of configuration issues. Performing replacements during peak usage hours can cause disruptions, and replacing all hardware components at the same time is unnecessary and can be costly. Documenting the replacement process is important for maintaining accurate records and troubleshooting future issues.

Explanation:
The native VLAN on a trunk port is used to carry untagged traffic across the trunk link. Any traffic that arrives on the trunk port without a VLAN tag is assigned to the native VLAN. Assigning a unique IP address, prioritizing traffic, and increasing bandwidth are not the purposes of configuring a native VLAN.

Explanation:
Bonding connects different parts of the electrical system to ensure safety by creating a low-resistance path to ground. This helps prevent electrical shock and equipment damage. Providing a backup power source, preventing unauthorized access, and enhancing data transmission speeds are not the primary purposes of bonding.

Explanation:
Wearing rubber-soled shoes provides insulation and helps protect against electrical shock. Ensuring the equipment is powered off before working on it is critical for safety. Using metal tools and working alone can increase the risk of accidents and are not recommended safety practices.
