Refer to the exhibit. What happens to the broadcast traffic when it reaches aggregation switches?

  1. Agg-2 switch receives broadcast packets and stops forwarding to the peer link on Agg-1 switch.
  2. Agg-1 switch prevents broadcast packets received on the vPC peer link from exiting the switch on ports Eth2/4 and Eth2/5.
  3. Agg-1 and Agg-2 switches receive broadcast packets and does not forward them to the peer link or the port channel.
  4. Only Agg-1 switch receives broadcast packets and does not forward to the peer link on Agg-2 switch.

Answer(s): B

Explanation:

Duplicate Frames Prevention in vPC
One of the most important forwarding rules for vPC is that a frame that enters the vPC peer switch from the peer link cannot exit the switch from a vPC member port.Figure shows switch-es 3 and 4 connected to 5k01 and 5k02 with vPCs Po51 and Po52. If one of the hosts connected to switch 4 sends either an unknown unicast or a broadcast, this traffic may get hashed to port eth2/2 on PortChannel 52. 5k02 receives the broadcast and needs to forward it to the peer link for the potential orphan ports on 5k01 to receive it.
Upon receiving the broadcast, 5k01 detects that this frame is coming from the vPC peer link. Therefore, it does not forward it to port 2/9 or 2/10; if it did, a duplicate frame on switch 3 or 4, respectively, would be created.
If a host on switch 4 sends a broadcast, 5k02 will correctly forward it to Po51 on port 2/9 and place it on the peer link. 5k01 will prevent this broadcast frame from exiting onto port 2/9 or 2/10 because this frame entered 5k01 from a vPC peer link. Should eth2/2 on switch 3 go down, port 2/9 on 5k01 would become an orphan port and as a result will receive traffic that traverses the peer link.

Which feature is supported with an In-Service Software Upgrade on a Cisco Nexus 9000 Series Switch?

  1. nondisruptive upgrades via nonstop forwarding
  2. configuration changes during an upgrade
  3. upgrades to individual modules and line cards
  4. zero downtime downgrades via dual supervisor modules

Answer(s): A

Explanation:

On a 95xx or 97xx Series MDS with dual supervisors, during the firmware upgrade, the new code is loaded on the standby supervisor. A switchover then occurs in order to make the supervisor that runs the new code active. The code is then loaded on the previously active supervisor, and it becomes the new standby supervisor. The data plane continues to pass fibre channel traffic. The modules then non-disruptively start at the lowest numbered module and proceed to the highest.
On a 91xx, 92xx, or 93xx Series MDS, which has only one supervisor, the supervisor (control plane) is reloaded. The data plane continues to pass fibre channel traffic.
If you intend to upgrade via Telnet, Secure Shell (SSH), or Simple Network Management Protocol (SNMP) (Fabric Manager/Device Manager), ensure that you have an Ethernet connection to both of the supervisors. After the Telnet session is lost during the upgrade, you must reconnect to the switch. You will connect to the previous standby supervisor now.

An engineer must configure a monitoring solution for a Cisco Nexus 9000 Series Switch based data center. The solution must provide real-time insight into the network health with subscription-based monitoring. The monitoring must be initiated from the client side, and the data must be sent via encryption. Which configuration steps complete the configuration?

  1. Configure Grafana on the Nexus switch. Specify the logging certificate. Enable syslog level 7 export to Grafana.
  2. Set the telemetry feature on the Nexus switch. Specify a certificate for telemetry transport. Configure a sensor group and destination.
  3. Activate SNMPv3 on the Nexus switch. Set the globalEnforcePriv parameter. Configure an SNMP agent to poll information.
  4. Enable GRPC on the Nexus switch. Generate a certificate. Configure gNMI inputs in Telegraf and output to InfluxDB.

Answer(s): B

Explanation:

About Telemetry -
Collecting data for analyzing and troubleshooting has always been an important aspect in monitoring the health of a network.
Cisco NX-OS provides several mechanisms such as SNMP, CLI, and Syslog to collect data from a network. These mechanisms have limitations that restrict automation and scale. One limitation is the use of the pull model, where the initial request for data from network elements originates from the client. The pull model does not scale when there is more than one network management station (NMS) in the network. With this model, the server sends data only when clients request it. To initiate such requests, continual manual intervention is required. This continual manual intervention makes the pull model inefficient.
A push model continuously streams data out of the network and notifies the client. Telemetry enables the push model, which provides near-real-time access to monitoring data.
