Q83. Which three authentication services are supported by Cisco NAC Appliance? (Choose three.) 

A. RADIUS 

B. LDAP 

C. Kerberos 

D. TACACS+ 

E. local 

F. SNMP 

Answer: A,B,C 


Q84. Which two services are provided at the aggregation layer in a data center design? (Choose two.) 

A. service module integration 

B. default gateway redundancy 

C. high-speed packet switching backplane 

D. network interface card teaming 

E. Layer 3 domain definitions 

Answer: A,B 


Q85. 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:


Q86. A designer should have which three technologies in the network before configuring MPLS Layer 3 VPNs? (Choose three.) 

A. MPLS 

B. LDP 

C. Cisco Express Forwarding 

D. VSS 

E. vPC 

F. VRRP 

Answer: A,B,C 


Q87. A network engineer must create a Layer 2 switch block design that has deterministic convergence and is loop-free at Layer 2. Which two switch block elements are needed to meet the requirements? (Choose two.) 

A. Layer 3 link between distribution switches 

B. HSRP with interface tracking on uplinks to core switches 

C. RPVST with equal bridge priority on distribution switches 

D. VLANs that do not span access switches 

E. Layer 2 link between distribution switches 

Answer: A,D 


Q88. Which two protocol characteristics should be most considered when designing a single unified fabric for the Data Center? (Choose two.) 

A. FCIP or FCoE allow for easier integration by using the Fibre Channel Protocol (FCP) and Fibre Channel framing 

B. iSCSI uses a special EtherType and an additional header containing additional control information 

C. FCIP and iSCSI has higher overhead than FCoE owing to TCP/IP 

D. FCoE was initially developed to be used as a switch-to-switch protocol, while FCIP is primarily meant to be used as an access layer protocol to connect hosts and storage to a Fibre Channel SAN 

E. FCoE requires gateway functionality to integrate into an existing Fibre Channel network 

Answer: A,C 


Q89. When is a first-hop redundancy protocol needed in the distribution layer? 

A. when the design implements Layer 2 between the access and distribution blocks 

B. when multiple vendor devices need to be supported 

C. when preempt tuning of the default gateway is needed 

D. when a robust method of backing up the default gateway is needed 

E. when the design implements Layer 2 between the access switch and the distribution blocks 

Answer:

B. IVR 

C. SCSI 

D. NAS
