QUESTION 52
Which event occurs when network broadcast traffic reaches the Storm Control threshold, assuming Storm Control is enabled at the switch?

A.    Switch port bandwidth is extended, based on the pre-configured peak bandwidth.
B.    The switch port forwards broadcast traffic partially, maintaining the traffic rate below the threshold level.
C.    The switch port blocks broadcast traffic and drops subsequent broadcast frames over the next time interval.
D.    Switch port bandwidth is extended, based on the pre-configured share value.

Answer: D

QUESTION 53
What is enabled by using NIC teaming?

A.    Failover to another available physical NIC in the event of a physical NIC failure

C.    Allocation of bandwidth to broadcast, multicast, and unicast traffic, based on priority
D.    Transfer of data to a LUN on a FC storage system using multiple network links

Answer: A

QUESTION 54
Click the calculator icon in the upper left-hand corner. An administrator has configured the following traffic shaping parameters for a distributed virtual
switch: Average bandwidth: 1 Kb/s Peak bandwidth: 4 Kb/s Burst size: 3 Kb What happens if a 6
Kb/s burst of data arrives at the switch port?

A.    Some of the frames of the burst will be queued or dropped by the switch.
B.    The burst will remain for 0.5 seconds without queuing or dropping frames.
C.    The burst will remain for 1.5 seconds without queuing or dropping frames.
D.    All the frames of the burst will be dropped.

Answer: A

QUESTION 55
Which is a component of Cisco Nexus 1000V?

A.    Virtual Switch Node
B.    Virtual Supervisor Module
C.    Virtual Internet Module
D.    Virtual Service Node

Answer: B

QUESTION 56
Under which condition of communicating nodes does routing occur across virtual networks?

A.    When they are on different virtual networks, but belong to the same physical network
B.    When they are on the same virtual network, but belong to different physical networks
C.    When they are on the same virtual network and physical network
D.    When they are located on different geographic locations, but belong to the same virtual network

Answer: A

QUESTION 57
Which is a function of a virtual switch?

A.    Directs network traffic to and from virtual machines
B.    Maintains MAC address table to perform OSI layer 3 operations
C.    Shares bandwidth of a physical NIC with other virtual switches
D.    Enables configuring load balancing policies across virtual HBA ports

Answer: A

QUESTION 58
What is a purpose of uplink ports on a virtual switch?

A.    To provide connectivity between a virtual switch and virtual NICs
B.    To enable inter-switch links (ISLs) between virtual switches in a physical server
C.    To enable the hypervisor kernel to access FC storage
D.    To provide connectivity between a virtual switch and physical NICs

Answer: D

QUESTION 59
Which statement best defines the term “virtual machine port group”?

A.    It is a mechanism for applying uniform network policy settings to a group of virtual machine ports.
B.    It is a method for transferring virtual machine traffic through a single network connection.
C.    It is a method for enabling communication between virtual machines, regardless of their location.
D.    It is a mechanism for assigning a VSAN ID to a group of virtual machine ports.

Answer: A

QUESTION 60
What is a principal benefit of deploying a distributed virtual switch?

A.    It maintains consistent network policies when virtual machines migrate across physical servers.
B.    It aggregates both physical and virtual switches distributed across virtualized data centers.
C.    It enables physical NICs to use MAC addresses for transmission of frames.
D.    It eliminates the requirement of individually configuring policies to hypervisor kernel ports.
