Refer to the exhibit. An engineer needs to implement streaming telemetry on a Cisco MDS 9000 Series Switch. The requirement is for the show command data to be collected every 30 seconds and sent to receivers. Which command must be added to the configuration to meet this requirement?
Answer : A
Link the sensor group with an ID to the subscription node and set the data streaming sample interval in milliseconds: switch(conf-tm-sub)# snsr-grp id sample-interval interval
Note: The minimum streaming sample interval that is recommended is 30000.

An engineer must configure OSPF in the data center. The external routes have already been redistributed into OSPF. The network must meet these criteria:
* The data center servers must reach services in the cloud and the services behind the redistributed routes.
* The exit point toward the Internet should be propagated only when there is a dynamically learned default route from the upstream router.
Which feature is required?
Answer : C
The ג€default-information originateג€ command will not advertise to any other routers without a default route in the routing table. When added the ג€alwaysג€ keyword, it tells the router to advertise a default route to other routers even if you don't have a default route in the routing table.
An engineer must configure a VXLAN routing on a Cisco Nexus 9000 Series Switch. The engineer requires a solution where all the leaf switches have the same gateway MAC and IP addresses. Which configuration set accomplishes this task?
Answer : A
- Enable VxLAN with distributed anycast-gateway using BGP EVPN fabric forwarding anycast-gateway-mac 0000.2222.3333
- Create server facing SVI and enable distributed anycast-gateway interface Vlan1001 no shutdown vrf member vxlan-900001 ip address 4.1.1.1/24 ipv6 address 4:1:0:1::1/64 fabric forwarding mode anycast-gateway

An engineer implements an ACI fabric and must implement microsegmentation of endpoints within the same IP subnet using a network-based attribute. The attribute mapping must allow IP subnet independence. Which attribute must be selected?
Answer : D
If you want to use a network-based attribute and classify IP addresses in the same subnet, you must use the MAC-based network attribute. IP-based microsegmented EPGs do not support classification for IP addresses in the same subnet. IP-based microsegmented EPGs are supported only when traffic requires Layer 3 routing. If the traffic is bridged, the microsegmentation policy cannot be enforced.

What is a characteristic of the install all command on the Cisco Nexus Series Switch?
Answer : A
Benefits of Using the install all Command
The install all command provides the following benefits:
ג€¢ You can upgrade the entire switch using just one procedure command.
ג€¢ You can receive descriptive information on the intended changes to your system before you continue with the installation.
ג€¢ You have the option to cancel the command. Once the effects of the command are presented, you can continue or cancel when you see this question (the default is no):
Do you want to continue (y/n) [n] :y
ג€¢ You can upgrade the entire switch using the least disruptive procedure.
ג€¢ You can see the progress of this command on the console, Telnet, and SSH screens:
ג€" After a switchover process, you can see the progress from both the supervisor modules.
ג€" Before a switchover process, you can only see the progress from the active supervisor module.
ג€¢ The command automatically checks the image integrity. This includes the running kickstart and system images.

An engineer must configure the HSRP protocol to implement redundancy using two Cisco Nexus Series Switches, in addition, me HSRP must meet these requirements:
* switch1 must retain the primary role if switch2 goes offline.
* switch1 must retain the primary role until normal conditions are restored.
* switch1 and switch2 must ensure that the routing tables are converged before taking the active role.
* switch2 must retain the primary role if the default gateway is not reachable.
Drag and drop the configuration commands from the right to the left to meet the requirements. The commands are used more than once. Not all commands are used.

Refer to the exhibit. During a vPC peer switch reload, there is packet loss between the server and the router. Which action must be taken to prevent this behavior during future reloads?
Answer : B
After a vPC peer device reloads and comes back up, the routing protocol needs time to reconverge. The recovering vPCs leg may black-hole routed traffic from access to aggregation/core until uplink Layer 3 connectivity is re-established. vPC Delay Restore feature delays vPCs leg bring-up on the recovering vPC peer device. vPC Delay Restore allows for Layer 3 routing protocols to converge before allowing any traffic on vPC leg. This results in a more graceful restoration and zero packet loss during the recovery phase (traffic still gets diverted on the alive vPC peer device). This feature is enabled by default with a vPC restoration default timer of 30 seconds. The timer can be tuned according to a specific Layer
3 convergence baseline from 1 to 3600 seconds.

A Cisco ACI engineer must configure an access port on a Cisco ACI leaf switch. The access policy should be configured so that it supports L3Out connectivity concurrently with several EPGs that are mapped to this interface with the static port method. How should the access policy be configured?
Answer : A
The access policy (the interface policy group) needs to have one single Attachable Access Entity Profile assigned since it is the same interface. Then different physical domains can be used for the routed and switched domain.
Refer to the exhibit. An engineer monitors ingress traffic from Host-A and all traffic for VLAN 20 from Host-B. Which configuration must be implemented to monitor and export traffic to Network Analyzer?
Answer : B

Refer to the exhibit. Which action completes the vPC domain implementation?
Answer : D
The physical interfaces need to be added to the Portchannel group. Configuring allowed VLANs on the vPC peer-link is optional.
Refer to the exhibit. A network engineer is implementing a configuration checkpoint on a Cisco Nexus 9000 Series Switch. The configuration must skip any existing vPC configuration errors and must complete if there are any configuration errors. The engineer finished the vPC domain configuration part. Which command completes the checkpoint implementation?
Answer : A
The available options are:
1. atomic(default) Rollback only if there are no errors
2. Best-Effort: Rollback and skip any errors
3. Stop at First Failure : Rollback and stop if an error occurs

An engineer must perform a software upgrade on a production Cisco Nexus 7000 Series Switch. Before the upgrade activity, the requirement is for all ports to be shut down and routing protocols to terminate gracefully. Which feature must be used to meet these requirements?
Answer : C
You can use maintenance mode to isolate a switch from the network in order to perform debugging or an upgrade. When switch maintenance is complete, you can return the switch to normal mode.
When you place the switch in maintenance mode, all protocols are gracefully brought down and all physical ports are shut down. When normal mode is restored, all the protocols and ports are brought back up.
