Q1. Which network virtualization technology provides logical isolation of network traffic at Layer 3?
A. VSS
B. VLAN
C. VRF-Lite
D. MEC
Answer: C
Q2. Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer?
A. Layer 3 routing between the Access and Aggregation layers facilitates the ability to span VLANs across multiple access switches, which is a requirement for many server virtualization and clustering technologies.
B. "East-west" server-to-server traffic can travel between aggregation modules by way of the core, but backup and replication traffic typically remains within an aggregation module.
C. Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.
D. Virtualization tools allow a cost effective approach for redundancy in the network design by using two or four VDCs from the same physical switch.
Answer: C
Q3. A company requires real-time SAN replication between two remote locations. What is the standard path selection protocol for fabric routing?
A. FSPF
B. FICON
C. FCOE
D. SCSI
Answer: A
Q4. A network design engineer has been asked to reduce the size of the SPT on an IS-IS broadcast network. Which option should the engineer recommend to accomplish this task?
A. Configure the links as point-to-multipoint.
B. Configure QoS in all links.
C. Configure a new NET address.
D. Configure the links as point-to-point.
Answer: D
Q5. Which routing protocol provides the fastest convergence and greatest flexibility within a campus environment?
A. OSPF
B. IS-IS
C. BGP
D. EIGRP
Answer: D
Q6. What are two of Cisco's best practices at the access layer to ensure rapid link transitions and VLAN consistency? (Choose two.)
A. Deploy RPVST
B. Deploy MSTP
C. Utilize VTP in server/client mode
D. Utilize VTP in transparent mode
E. VLANs span entire network
F. Portfast applied on distribution uplinks
Answer: A,D
Q7. To which switch or switches should you provide redundant links in order to achieve high availability with reliable fast convergence in the enterprise campus?
A. to a core switch running Cisco NSF and SSO from redundant distribution switches connected with a Layer 2 link
B. to a core switch running Cisco NSF and SSO from redundant distribution switches connected with a Layer 3 link
C. to two core switches from redundant distribution switches connected with a Layer 2 link
D. to two core switches from redundant distribution switches connected with a Layer 3 link
E. to two core switches running Cisco NSF and SSO from two redundant distribution switches running Cisco NSF and SSO
Answer: D
Q8. Which part of the Layer 3 header is used to identify a flow in NetFlow but it is not used for NBAR?
A. source port
B. ToS
C. protocol type
D. source IP
Answer: B
Q9. Which ISP technology can be implemented as a service when designing a topology to perform extranet connectivity via multitenant segmentation from within a corporate intranet?
A. Cisco Easy VPN
B. GRE over IPsec
C. MPLS
D. VTI
E. VPNaaS
Answer: C
Q10. 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
