MODULE 7. NETWORK ARCHITECTURE QUESTIONS AND ANSWERS #7
1. What software allows you to define VMs and manage resource allocation and sharing among
VMs on a host computer?: Hypervisor
2. What virtual, logically defined device operates primarily at the data link layer to pass frames
between nodes?: Virtual switch
3. Which device can manage traffic to multiple servers in a cluster so all servers equally share
the traffic?: Load balancer
4. With which network connection type does the VM obtain IP addressing information from its
host?: NAT mode
5. Which type of switch connects all devices in a rack to the rest of the network?: ToR
switch
6. Which cloud service model gives software developers access to multiple platforms for testing
code?: PaaS
7. When shopping for a new router, what does the MTBF tell you?: How long devices like this one
will last on average until the next failure
8. What information does the switchport port-security command use to re- strict access to a
switch's interface?: MAC address
9. Which of the following features of a network connection between a switch and server is not
improved by link aggregation?: Speed
10.Which cloud management technique executes a series of tasks in a work- flow?: Orchestration
11.As a network administrator, you want to modernize your network with modular software running
on standard server platforms. You want to start by replacing traditional, custom-designed network
equipment. You also wish to have flexible, cost-saving options for many types of network devices,
including virtual servers, data storage, load balancers, and firewalls. Which of the following will you
use in such a scenario?: NFV
12.Which of the following is a multipath link-state protocol?: TRILL
13.You are working as one of the network administrators of Wells & Welsh Associates. The company
wants to provide network administrators with more centralized control of network settings and
management. For this reason, the department has decided to use an SDN (software-defined
networking) con- troller to allow network administrators to remotely manage network devices and
monitor data collected about these devices. Which plane of the SDN will enable you to allow such a
feature?: The management plane
14. Which of the following planes is made up of the physical or virtual devices that receive and send
network messages on their way to their destinations?-
: The infrastructure plane
