Q1. Which option describes the effect of using softphones instead of VoIP handsets on QoS implementation for the voice traffic? 

A. It provides a Layer 2 CoS marking in the frames that can be used for QoS implementation. 

B. Using softphones means that 802.1Q tagging must be configured between the PC and the switch. 

C. The voice traffic of softphones is mixed with data traffic of PC on the access VLAN. 

D. By using softphones, the implementation of a QoS depends only on trusting DSCP markings set by the PC. 

Answer: C 

Q2. What SAN technology can accomplish fabric infrastructure implementation using multiple fabrics? 

A. VSAN 

B. IVR 

C. SCSI 

D. NAS 

Answer: A 

Q3. CoS is applied for Layer 2 markings in an Ethernet environment. Which protocol must be configured on the Layer 2 switch port for CoS to work? 

A. MPLS 

B. IEEE 802.1W 

C. IEEE 802.1Q 

D. IEEE 802.1S 

Answer: C 

Q4. Support of vPC on the Cisco Nexus 5000 access switch enables various new design options for the data center Access layer, including which of the following? 

A. The vPC peer link is not required for Access layer control traffic, and can instead be used to span VLANs across the vPC access switches 

B. A single switch can associate per-interface with more than one vPC domain 

C. vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built between the access and aggregation switches 

D. Allows an EtherChannel between a server and a access switch while still maintaining the level of availability that is associated with dual-homing a server to two different access switches 

Answer: C

D. granular monitoring 

Answer: A 

Q6. What is an advantage of using the Virtual Device Contexts feature in a data center environment? 

A. The same VLAN cannot be configured in separate Virtual Device Contexts. 

B. This feature provides fault domain separation.

B. when a VLAN spans access layer switches to support business applications 

C. when trunks need to extend multiple VLANs across access switches 

D. when it is necessary to speed up network convergence in case of link failure 

Answer: A
