E. VLANs span entire network
F. Portfast applied on distribution uplinks
Q23. Which statement about the ToR design model is true?
A. It can shorten cable runs and simplify rack connectivity.
B. Each ToR switch must be individually managed.
C. Multiple ToR switches can be interconnected to provide a loop-free spanning-tree infrastructure.
D. It can connect servers that are located in separate racks.
Q24. 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
Q25. What are two advantages of using Cisco FEX devices in the data center design? (Choose two.)
A. Traffic-forwarding decisions are made by the Cisco FEX device.
B. Cisco FEX devices must be upgraded when the parent switch is upgraded.
C. Traffic-forwarding decisions are made by the parent switch, resulting in easier troubleshooting and centralized management.
D. Cisco FEX devices do not have to be upgraded when the parent switch is upgraded, resulting in cost savings.
E. Cisco FEX devices can be part of two different VDCs.
Q26. Which three statements about Network Attached Storage are correct? (Choose three.)
A. Data is accessed using NFS or CIFS.
B. Data is accessed at the block level.
C. NAS is referred to as captive storage.
D. Storage devices can be shared between servers.
E. A NAS implementation is not as fast as a DAS implementation.
Q27. Addressing QoS design in the Enterprise Campus network for IP Telephony applications means what?
A. It is critical to identify aggregation and rate transition points in the network, where preferred traffic and congestion QoS policies should be enforced
B. Suspect traffic should be dropped closest to the source, to minimize wasting network resources
C. An Edge traffic classification scheme should be mapped to the downstream queue configuration
D. Applications and Traffic flows should be classified, marked and policed within the Enterprise Edge of the Enterprise Campus network
Q28. Which of the following two are effective and simple means of employing route summarization within the Enterprise Campus network? (Choose two)
A. A default route (0.0.0.0 /0) advertised dynamically into the rest of the network
B. Route filtering to manage traffic flows in the network, avoid inappropriate transit traffic through remote nodes, and provide a defense against inaccurate or inappropriate routing updates
C. Use manual split horizon
D. Use a structured hierarchical topology to control the propagation of EIGRP queries
E. Open Shortest Path First (OSPF) stub areas
Q29. Which statement about vPC technology is true?
A. It allows a device to connect to two separate upstream devices as if they were a single device.
B. It provides the ability to pair two servers in the data center.
C. It promotes better STP designs in the switching infrastructure.
D. It supports IEEE 802.1Q only.
Q30. Refer to the exhibit.
A network engineer manually reconfigures the BGP configuration on newly upgraded router R1. However, the BGP neighbor relationship does not come up with the directly connected neighbor router. What is causing the failure of the BGP neighbor relationship between routers R1 and R2?
A. An incorrect neighbor IP address for router R2 is configured on router R1.
B. An incorrect neighbor AS number is configured on router R1 for router R2.
C. The wrong BGP authentication password is configured on router R1.
D. Router R1 must configure the R2 loopback address as the neighbor IP address.
