Which three guidelines and limitations of policy-based routing are true? (Choose three.)

• A: A match command can refer to more than one ACL in a route map for policy-based routing.
• B: Setting a tunnel interface or an IP address via a tunnel interface as a next hop in a police-based routing policy is not supported.
• C: The same route map can be shared among different interfaces for policy-based routing as long as interfaces belong to the same VRF instance.
• D: An ACL used in a policy-based routing route map cannot include a deny statement.
• E: A policy-based routing route map can have multiple match or set statements per route-map statement.
• F: Policy-based routing and WCCPv2 are not supported on the same interface if bank chaining is disabled.

• E: ordinary clock
• F: crystal clock

Correct Answer: CDE

Which two options are functions of the 6LoWPAN header? (Choose two.)

• A: packet fragmentation and reassembly
• B: limit the lifespan of a packet (TTL)
• C: IPv6 header compression
• D: cyclic redundancy check
• E: Layer 2 encryption

Correct Answer: AC

Which three options are benefits of the vPC peer switch feature? (Choose three.)

• A: After the peer link comes up, it performs an ARP bulk sync over CFSoE to the peer switch
• B: It improves convergence forLayer 3 flows.
• C: It allows a pair of vPC peer devices to appear as a single STP root in the Layer 2.
• D: It simplifies STP configuration by configuring both vPC with the same STP priority.
• E: It eliminates the recommendation to pin the STP root to the vPCprimary switch.

Correct Answer: CDE

Which two guidelines apply to private VLAN configuration when you are running FabricPath (Choose two.)

• A: On the F-Series modules, user-configured static MAC addresses are programmed on all forwarding engines that have ports in that VLAN.
• B: The system does support hierarchical static MAC addresses.
• C: FabricPath ports can be put into a private VLAN.
• D: All VLANs in a private VLAN must be in the same VLAN mode; either CE or FabricPath.

Correct Answer: AD

Which three main functions are provided by OTV to achieve failure isolation? (Choose three.)

• A: optimal outbound routing
• B: unknown Unicast traffic suppression
• C: ARP optimization
• D: use of multiple OTV overlays
• E: Spanning Tree isolation
• F: unicast policy control

Correct Answer: BCE

• A: Outer S-IP = IP-1 ; Outer D-IP = IP-2.
• B: Outer S-IP = IP-A : Outer D-IP = IP-B.
• C: Outer S-MAC = MAC-1 ; Outer D-MAC= MAC-4.
• D: Outer S-MAC = NAC-A ; Outer D-MAC = MAC-B.
• E: Outer S-IP = IP-1 ; Outer D-IP = IP-4.

Which two guidelines and limitations of NetFlow on Cisco NX OS are true? (Choose two.)

• A: The Cisco Nexus 2000 Series Fabric Extender does not support bridged NetFlow.
• B: If you change a Layer 2 interface to a Layer 3 interface, the software converts the Layer 2 NetFlow to Layer 3 NetFlow automatically.
• C: You must configure a sourceinterface. If you do not configure a source interface, the exported remains in a disables state.
• D: Valid record name is optional to configure.
• E: Only Layer 2 NetFlow is applied on Layer 2 interfaces, and only Layer 3 NetFlow is applied on Layer 3 interfaces.

Correct Answer: CE

Which three statements are true about redistribution of routes from L3Outs in an ACI fabric? (Choose three.)

• A: ACI fabric runs MP-BGP.
• B: Route control subnets control the exchange of routing information (prefixes) into and out of the fabric (control plane).
• C: Routes are nor redistributed to leaf switches where the same VRF is present.
• D: Routes learned from L3Outs on border leaf switches are not redistributed into MP-BGP at the ingress leaf.
• E: Security import subnets control the forwarding of packets into and out of L3Out connections (data plane).
• F: The routes are advertised to all external Layer 3 Outside connections.

Correct Answer: ABE

Which two statements about CFS are true? (Choose two.)

• A: CFS distributes the local NTP configuration to masteronly which then forwards to all devices in network.
• B: After enabling CFS, a network-wide lock is applied to NTP whenever an NTP configuration is started and released once after the change has been committed or discarded.
• C: If CFS is used to distribute NTP, all devices in the network must have the different VRFs configured then as used for NTP.
• D: You must manually distribute NTP authentication keys on the NTP server and Cisco NX-OS devices across the network.

Correct Answer: BD
