Which statement about scalability in Cisco OTV is true?
- A . The control plane avoids flooding by exchanging MAC reachability.
- B . IP-based functionality provides Layer 3 extension over any transport.
- C . Any encapsulation overhead is avoided by using IS-IS.
- D . Unknown unicasts are handled by the authoritative edge device.
Which two statements about Cisco Nexus 7000 line cards are true? (Choose two.)
- A . M1, M2, and F1 cards are allowed in the same VDC.
- B . M line cards are service-oriented and likely face the access layer and provide Layer 2 connectivity.
- C . F line cards are performance-oriented and likely connect northbound to the core layer for Layer 3 connectivity.
- D . M line cards support Layer 2, Layer 3, and Layer 4 with large forwarding tables and a rich feature set.
- E . The F2 line card must reside in the admin VDC.
Which statement about the Layer 3 card on the Cisco Nexus 5500 Series Switch is true?
- A . BGP support is not provided, but RIP, EIGRP, and OSPF support is provided.
- B . Up to two 4-port cards are supported with up to 160 Gb/s of Layer 3 forwarding capability.
- C . Up to 16 FEX connections are supported.
- D . Port channels cannot be configured as Layer 3 interfaces.
Which statement explains why a Cisco UCS 6200 Fabric Interconnect that is configured in end- host mode is beneficial to the unified fabric network?
- A . There is support for multiple (power of 2) uplinks.
- B . Upstream Layer 2 disjoint networks will remain separated.
- C . The 6200 can connect directly via vPC to a Layer 3 aggregation device.
- D . STP is not required on the uplink ports from the 6200.
Which option is a restriction of the unified ports on the Cisco UCS 6200 Series Fabric Interconnect when connecting to the unified fabric network?
- A . Direct FC connections are not supported to Cisco MDS switches
- B . The FCoE or Fibre Channel port allocations must be contiguous on the 6200.
- C . 10-G Fibre Channel ports only use SFP+ interfaces.
- D . vPC is not supported on the Ethernet ports.
Which statement about the implementation of Cisco TrustSec on Cisco Nexus 7000 Series Switches is true?
- A . While SGACL enforcement and SGT propagation are supported on the M and F modules, 802.1AE (MACsec) support is available only on the M module.
- B . SGT Exchange Protocol is required to propagate the SGTs across F modules that lack hardware support for Cisco TrustSec.
- C . AAA authentication and authorization is supported using TACACS or RADIUS to a Cisco Secure Access Control Server.
- D . Both Cisco TrustSec and 802.1X can be configured on an F or M module interface.
Which statement about implementation of Cisco TrustSec on Cisco Nexus 5546 or 5548 switches are true?
- A . Cisco TrustSec support varies depending on Cisco Nexus 5500 Series Switch model.
- B . The hardware is not able to support MACsec switch-port-level encryption based on IEEE 802.1AE.
- C . The maximum number of RBACL TCAM user configurable entries is 128k.
- D . The SGT Exchange Protocol must use the management (mgmt 0) interface.
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
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 password.
Which statement about RADIUS configuration distribution using Cisco Fabric Services on a Cisco Nexus 7000 Series Switch is true?
- A . Cisco Fabric Services does not distribute the RADIUS server group configuration or server and global keys.
- B . Enabling Cisco Fabric Services causes the existing RADIUS configuration on your Cisco NX- OS device to be immediately distributed.
- C . When the RADIUS configuration is being simultaneously changed on more than one device in a Cisco Fabric Services region, the most recent changes will take precedence.
- D . Only the Cisco NX-OS device with the lowest IP address in the Cisco Fabric Services region can lock the RADIUS configuration.
