NEW QUESTION 1
Which two security features are only supported on the Cisco Nexus 7000 Series Switches? (Choose two.)
- A. IP source guard
- B. traffic storm control
- C. CoPP
- D. DHCP snooping
- E. Dynamic ARP Inspection
- F. NAC
A traffic storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. You can use the traffic storm control feature to prevent disruptions on Layer 2 ports by a broadcast, multicast, or unicast traffic storm on physical interfaces.
Traffic storm control (also called traffic suppression) allows you to monitor the levels of the incoming broadcast, multicast, and unicast traffic over a 10-millisecond interval. During this interval, the traffic level, which is a percentage of the total available bandwidth of the port, is compared with the traffic storm control level that you configured. When the ingress traffic reaches the traffic storm control level that is configured on the port, traffic storm control drops the traffic until the interval ends.

NEW QUESTION 17
FabricPath switch-id is 25 and load-balance is configured for L3/L4 and rotate amount is 14 byte. What information is true about FabricPath switch-id?
- A. FabricPath topology requires manual configuration of switch-id which has a range from 1 to 4095
- B. Every FabricPath must have a manually configured switch-id for it to form a FabricPath topology
- C. FabricPath topology requires manual configuration of switch-id which has a range from 1 to 4099
- D. You do not have to manually assign a switch ID unless you are running a virtual port channel plus (vPC+) because the system assigns a switch ID for you when you enable FabricPath
fabricpath switch-id (vPC)
To configure a virtual port channel plus (vPC+) switch ID, use the fabricpath switch-id command. To remove the FabricPath switch from a vPC domain, use the no form of this command.
fabricpath switch-id switch-id
no fabricpath switch-id [ switch-id ] Usage Guidelines
You do not have to manually assign a switch ID (unless you are running a vPC+); the system assigns a switch ID for you when you enable FabricPath.
Note You must assign the same vPC+ switch ID to each of the two vPC+ peer devices before they can form an adjacency.
This command requires an Enhanced Layer 2 license. Examples
This example shows how to configure a vPC+ switch ID on a FabricPath-enabled device: switch# configure terminal
switch(config)# vpc domain 1
switch(config-vpc-domain)# fabricpath switch-id 1
Configuring fabricpath switch id will flap vPCs. Continue (yes/no)? [no]

NEW QUESTION 19
By default it will take 10 seconds for authentication to fail due to an unresponsive RADIUS server before a Cisco Nexus series switch reverts to another RADIUS server or local authentication. What is one efficient way to improve the reaction time to a RADIUS server failure?
- A. Decrease the global RADIUS retransmission count to 1.
- B. Decrease the global RADIUS timeout interval to 5 seconds.
- C. Configure the RADIUS retransmission count and timeout interval per server, versus globally.
- D. Configure per server a test idle timer, along with a username and passwor
You can monitor the availability of RADIUS servers. These parameters include the username and password to use for the server and an idle timer. The idle timer specifies the interval during which a RADIUS server receives no requests before the Nexus 5000 Series switch sends out a test packet. You can configure this option to test servers periodically. The test idle timer specifies the interval during which a RADIUS server receives no requests before the Nexus 5000 Series switch sends out a test packet. The default idle timer value is 0 minutes. When the idle time interval is 0 minutes, the Nexus 5000 Series switch does not perform periodic RADIUS server monitoring.

NEW QUESTION 22
Which two items are services that are provided by Cisco Fabric Services? (Choose two.)
- A. device alias distribution
- B. VLAN database distribution
- C. Kerberos proxy distribution
- D. RSA key pair distribution
- E. DPVM configuration distribution
The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient database management and distribution. Device aliases use the coordinated distribution mode and the fabric-wide distribution scope.
DPVM can use CFS to distribute the database to all switches in the fabric. This allows devices to move anywhere and keep the same VSAN membership. You should enable CFS distribution on all switches in the fabric. Using the CFS infrastructure, each DPVM server learns the DPVM database from each of its neighboring switches during the ISL bring-up process. If you change the database locally, the DPVM server notifies its neighboring switches, and that database is updated by all switches in the fabric.

Which three items must be configured in the port profile client in Cisco UCS Manager? (Choose three.)
- A. port profile
- B. DVS
- C. data center
- D. folder
- E. vCenter IP address
- F. VM port group
After associating an ESX host to a DVS, you can migrate existing VMs from the vSwitch to the DVS, and you can create VMs to use the DVS instead of the vSwitch. With the hardware-based VN-Link implementation, when a VM uses the DVS, all VM traffic passes through the DVS and ASIC-based switching is performed by the fabric interconnect.
In Cisco UCS Manager, DVSes are organized in the following hierarchy: vCenter
Folder (optional) Datacenter Folder (required) DVS
At the top of the hierarchy is the vCenter, which represents a VMware vCenter instance. Each vCenter contains one or more datacenters, and optionally vCenter folders with which you can organize the
datacenters. Each datacenter contains one or more required datacenter folders. Datacenter folders contain the DVSes.
