Which Layer 2 technology extends to access layer devices, allowing individual switch ports to be assigned for network and traffic management in an enterprise network?
- A. VLANs
- B. BGP
- C. OSPF
- D. MPLS
Answer: A
Explanation:
In an enterprise network,Virtual Local Area Networks (VLANs)are the key Layer 2 technology used to logically segment a network into multiple broadcast domains. VLANs allow network administrators to assign individual switch ports to specific VLANs, enabling effective network segmentation and traffic management.
This configuration extends to access layer devices, such as switches where end-user devices connect. By isolating traffic into VLANs, administrators can improve network performance, enhance security by separating sensitive departments (such as finance and HR), and simplify network management.
Unlike routing protocols such as BGP and OSPF, which operate at Layer 3, or MPLS, which is a Layer 2.5 forwarding technology used primarily in service provider networks, VLANs are explicitly designed for Layer
2 segmentation within LAN environments.

NEW QUESTION # 70 
Refer to the exhibit. What is the redundancy implementation in this Cisco UCS architecture?
- A. The system uses a single point of connectivity, relying on internal redundancy within each UCS chassis.
- B. Redundancy is limited to the uplink connections, with no failover capabilities between the fabric interconnects.
- C. Redundancy is achieved through dual fabric interconnects, providing separate paths for FCoE, FC, and LAN traffic.
- D. Redundancy is implemented at the chassis level only, with chassis 1 acting as a backup for chassis 2.
Answer: C
Explanation:
In the providedCisco 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 bothCisco UCS Chassis 1 and 2through I/O Modules (IOMs).
This is theclassic active-active UCSdesign, providingfull path redundancyfor all traffic types:
* LAN uplinksare handled separately by Fabric Interconnect B.
* SAN trafficis distributed throughFC uplinksandFCoE uplinksvia Fabric Interconnects A and B.
* Each server in the chassis canfail over its traffic to the alternate fabric if one interconnect fails.
This architecture guaranteesno single point of failure, which is essential inmission-critical environments like data centers and enterprise server farms.
NEW QUESTION # 71
What happens to the switch operation when a supervisor module in a Cisco Nexus switch is replaced by two supervisor modules?
- A. The switch continues to operate without any interruption.
- B. The switch shuts down completely.
- C. All modules in the switch are reset due to a stateless switchover.
- D. Only the affected line cards reset.
Answer: C
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.
