35
Q

This command saves the running configuration into the startup configuration

A

36
Q

This command targets a range of interfaces to configure all at once

A

interface range {range}
ex: int range fa0/1 - 3

37
Q

__________ __________ is unidirectional data flow in which a device can either send or receive on an Ethernet LAN — but not both at the same time

A

half duplex

38
Q

This duplex mode increases the effective bandwidth by allowing both ends of a connection to transmit and receive data simultaneously. This is known as bidirectional

A

full duplex

39
Q

Manually setting the duplex mode and speed of switch ports can cause issues if one end is __________ or set to __________

A

Mismatched
Autonegotiation

40
Q

When this feature is enabled, the interface automatically detects the required cable connection type (straight-through or crossover) and configures the connection appropriately

A

Auto-MDIX

41
Q

This ethernet standard requires Auto-MDIX

A

Gigabit Ethernet Standard

42
Q

When using Auto-MDIX on an interface, the interface speed and duplex must be set to __________ so that feature operates correctly

A

auto

43
Q

True or False: Pinging the loopback address of a host should succeed whether or not the host is connected to the network

A

True

44
Q

If a loopback ping fails then what would that indicate?

A

A software or hardware problem on the host itself

45
Q

What 3 steps systematically test connectivity and in what order order do those steps belong?

A

Can a device ping itself? (loopback)
Can an end device ping its gateway?
Can an end device ping the destination?

46
Q

From a PC, the best command tool to use to find a break in the traffic or network path is what?

A

tracert

47
Q

What is the line status and protocol status for this typical root cause of a switch interface status—

The interface is configured with the shutdown command

A

Line status: Administratively down
Protocol: Down

48
Q

What is the line status and protocol status for this typical root cause of a switch interface status—

No cable exists, the cable is bad, incorrect cable pinouts are used, mismatch speed, device on the other end is powered off or the other interface is shutdown

A

Line status: Down
Protocol: Down

49
Q

What is the line status and protocol status for this typical root cause of a switch interface status—

This status is not expected on LAN switch interfaces. This indicates a Layer 2 issue on Layer 3 devices

A

Line status: Up
Protocol: Down

50
Q

What is the line status and protocol status for this typical root cause of a switch interface status—

Port security has disabled the interface. The network admin must manually reenable the interface

A

Line status: Down
Protocol: Down (errdisabled)

51
Q

What is the line status and protocol status for this typical root cause of a switch interface status—

The interface is working

A

Line status: Up
Protocol: Up

52
Q

Manually configuring both speed and duplex on a switch interface disables what?

A

The IEEE standard autonegotiation process

53
Q

What command would verify the speed and duplex of an interface

A

show interfaces status
show interface {int}

54
Q

If a duplex setting is set to full or half when viewing a show interfaces status command, does that mean duplex has been manually set or autoconfigured?

A

Manually set and autonegotiation has been disabled

55
Q

If a duplex setting is set to a-full when viewing a show interfaces status command, does that mean duplex has been manually set or autonegotiated?

A

It means the switch autonegotiated full duplex

56
Q

Even if duplex settings are mismatched what Line status and protocol will the interface show?

A

Up/Up

57
Q

What is the type of problem that is occurring when the counter value(s) say many input errors, few collisions?

A

Excessive noise caused by wrong cable category or EMI

58
Q

What is the type of problem and root cause that is occurring when the counter value(s) say more than roughly 0.1% of all frames are collisions?

A

Collisions caused by duplex mismatch or DOS attack

59
Q

What is the type of problem that is occurring when the counter value(s) have increasing late collisions?

A

Caused by collision domain, duplex mismatch or single cable too long
