CCNA Block 3

Which statement identifies the functionality of virtual machines?

• Virtualized servers run most efficiently when they are physically connected to a switch that is separate from the hypervisor

• The hypervisor can virtualize physical components including CPU, memory, and storage

• Each hypervisor can support a single virtual machine and a single software switch

• The hypervisor communicates on Layer 3 without the need for additional resources

An organization has decided to start using cloud-provided services. Which cloud service allows the organization to install its own operating system on a virtual machine?

• 
  

• • platform-as-a-service

  
  

• software-as-a-service

• network-as-a-service

• infrastructure-as-a-service

Anycompany has decided to reduce its environmental footprint by reducing energy costs, moving to a smaller facility, and promoting telecommuting. What service or technology would support this requirement?

• 
  

• Cisco ACI

• cloud services

• APIC-EM

• data center

What are two fundamentals of virtualization? (Choose two)

• The environment must be configured with one hypervisor that serves solely as a network manager to monitor SNMP traffic

• It allows logical network devices to move traffic between virtual machines and the rest of the physical network

• It allows multiple operating systems and applications to run independently on one physical server

• It allows a physical router to directly connect NICs from each virtual machine into the network

• It requires that some servers, virtual machines and network gear reside on the Internet

What role does a hypervisor provide for each virtual machine in server virtualization?

• 
  

• control and distribution of physical resources

• • software-as-a-service

  
  

• services as a hardware controller

• infrastructure-as-a-service

A manager asks a network engineer to advise which cloud service models are used so employees do not have to waste their time installing, managing, and updating software which is only used occasionally. Which cloud service model does the engineer recommend?

• 
  

• infrastructure-as-a-service

• software-as-a-service

• platform-as-a-service

• business process as service to support different types of service

Refer to the exhibit. After the switch configuration the ping test fails between PC A and PC B. Based on the output for switch 1, which error must be corrected?

• There is a native VLAN mismatch

• Access mode is configured on the switch ports.

• The PCs are in the incorrect VLAN

• All VLANs are not enabled on the trunk

Two switches are connected and using Cisco Dynamic Trunking Protocol. SW1 is set to Dynamic Desirable. What is the result of this configuration?

• 
  

• The link is in a downstate.

• The link is in an error disables stale

• The link is becomes an access port

• The link becomes a trunkport

Refer to exhibit. Which action do the switches take on the trunk link?

• The trunk does not form and the ports go into an err-disabled status

• The trunk forms but the mismatched native VLANs are merged into a single broadcast domain

• The trunk does not form, but VLAN 99 and VLAN 999 are allowed to traverse the link

• The trunk forms but VLAN 99 and VLAN 999 are in a shutdown state

Refer to the exhibit. The network administrator wants VLAN 67 traffic to be untagged between Switch 1 and Switch 2 while all other VLANs are to remain tagged. Which command accomplishes this task?

• switchport access vlan 67

• switchport trunk allowed vlan 67

• switchport private-vlan association host 67

• switchport trunk native vlan 67
