CompTIA Network+ Guide to Networks, 9th Edition - Module 7: Network Architecture

Flashcards covering Network Architecture concepts from Module 7, including switches, STP, SDN, virtualization, and cloud models.

Managed switches can be configured via a command-line interface or a ________ management GUI.

web-based

A Layer ________ switch is capable of interpreting layer 3 data and works like a router.

$$3$$

________ prevents traffic loops, or switching loops, by calculating paths that avoid loops and blocking links.

$STP$ ($Spanning$ $Tree$ $Protocol$)

$STP$ information is transmitted between switches via special messages called ________.

$BPDUs$ ($Bridge$ $Protocol$ $Data$ $Units$)

In Cisco, Huawei, and Arista devices, you can disable unused ports using the ________ command.

shutdown

A strategy of implementing security in multiple layers is called ________.

defense in depth

The ________ layer, or edge layer, consists of workgroup switches connected directly to hosts in a three-tiered architecture.

access

The flow of traffic between peers within a network segment is called ________ traffic.

east-west

Traffic that must leave the local segment to reach its destination is called ________ traffic.

north-south

Newer networks collapse the core and distribution layers into one layer called the ________.

spine

$SDN$ relies on a form of abstraction called ________ to separate functions of network devices into different planes.

disaggregation

The ________ plane in $SDN$ handles the decision-making processes.

control

The ________ plane is made up of physical or virtual devices that receive and send network messages.

infrastructure (or data)

________ is a storage networking architecture that runs separately from Ethernet networks to maximize speed of storage and access.

$FC$ ($Fibre$ $Channel$)

The SAN technology that can run over ordinary Ethernet NICs without special hardware is ________.

$iSCSI$ ($Internet$ $SCSI$)

A Type ________ hypervisor installs on a computer before any OS and is known as a bare-metal hypervisor.

$$1$$

In ________ mode, a $vNIC$ accesses the physical network using the host machine's NIC and obtains its own IP address from a $DHCP$ server.

bridged

In ________ mode, a $vNIC$ relies on the host machine to act as a $NAT$ device.

$$NAT$$

In ________ mode, VMs on one host can exchange data with each other and the host, but cannot reach nodes beyond the host.

host-only

The process of merging physical and virtual network architecture is known as ________.

$NFV$ ($Network$ $Functions$ $Virtualization$)

The cloud characteristic that allows storage capacity to quickly or automatically scale up or down is ________.

rapid elasticity

In the ________ service model, all hardware, software, and everything else is managed at the organization's location.

on-premises

________ is the process of using text-based commands in a configuration file to create and manage cloud resources.

$IaC$ ($infrastructure$ $as$ $code$)

A programmed, computer-generated response to a specific event is referred to as ________.

automation

Converting cloud maintenance tasks into code to run together in a complex workflow is called ________.

orchestration

The measure of time a system functions normally between failures is known as ________.

uptime

The average amount of time that will pass for devices exactly like this one before the next failure is expected is the ________.

$MTBF$ ($mean$ $time$ $between$ $failures$)

Identical components that can be changed while a machine is running are called ________.

hot-swappable

The combination of multiple network interfaces to act as one logical interface is known as ________.

link aggregation (or port aggregation)

________ coordinates communications between hosts on aggregated connections and offers static, passive, or active modes.

$LACP$ ($Link$ $Aggregation$ $Control$ $Protocol$)

A ________ is used to represent an entire cluster of grouped devices appearing as a single device.

$VIP$ ($virtual$ $IP$ $address$)
