Border Gateway Protocol (BGP) falls into the category of:

Answer 4

Hybrid routing protocols

Question 5

A manually configured routing table entry is known as:

Answer 5

Static route

Question 6

The term “Default route” refers to a “last resort” network path used by a router for forwarding all packets with destination addresses not listed in its routing table.

Answer 6

True

Question 7

In routing, the term “Administrative distance” refers to a value used in routers to tank routes from most preferred (high AD value) to least preferred (low AD value).

Answer 7

False

Question 8

Which of the following is an exterior gateway protocol?

Answer 8

BGP (Border Gateway Protocol)

Question 9

Which of the following answers refer(s) to (an) interior gateway protocol(s)? (Select all that apply)

Answer 9

RIP (Routing Information Protocol)
EIGRP(Enhanced Interior Gateway Routing Protocol)
OSPF (Open Shortest Path First)

Question 10

A field in an IP datagram that specifies how many more hops a packet can travel before being discarded is called:

Answer 10

TTL (Time To Live)

Question 11

Which of the following mechanisms can be used to prevent routing loops? (Select 2 answers)

Answer 11

Maximum hop count
Time to live (TTL)

Question 12

Which of the following terms refer to solutions used for controlling network resources and assigning priority to different types of traffic? (Select 2 answers)

Answer 12

Packet shaping
Quality of Service (QoS)

Question 13

Which of the terms listed below refers to a logical grouping of computers that allow computer hosts to act as if they were attached to the same broadcast domain regardless of their physical location?

Answer 13

VLAN

Question 14

Data from multiple VLANs on a single switch is carried through a single network link between switches. This is often referred to as “trunking” or “VLAN multiplexing”, and each of the switches has a special port (trunk port) configured to pass all the data, regardless of the VLAN number, between all switches on a LAN. To allow for multiple VLANs on one link, frames from individual VLANs must be identified. The most common and preferred method, IEEE 802.1Q, adds a tag to the Ethernet frame header labeling it as belonging to a certain VLAN.

Answer 14

True

Question 15

Which of the following solutions enables combining several physical ports of a switching device into a single logical channel?

Answer 15

LACP (Link Aggregation Control Protocol)

Question 16

Transmission carried out in one direction only is described as simplex mode. Communication that takes place only in one direction at a time is referred to as half-duplex mode. Two Devices communicating with each other in both directions simultaneously are said to be in full-duplex mode. Network devices supporting autonegotiation feature automatically configure best mode supported by both devices. Duplex mismatch is the term used for a situation where two devices communicate with each other using different duplex modes.

Answer 16

True

Question 17

Port mirroring allows an administrator to inspect traffic passing through a network switch. ON a switch that supports port mirroring, a packet analyzer can be connected to an empty port and switch can be configured to pass a copy of the data sent over one or multiple ports on that switch to the packet sniffer port allowing the administrator to monitor contents of the traffic passing through the switch.

Answer 17

True

Question 18

In the context of implementing secure network designs, the term “Port security” may aply to:

Answer 18

Disabling physical ports on a device
Implementing MAC address filtering
Disabling unused logical ports
Implementing Port-based Network Access Control (defined in the IEEE 802.1X standard_

Question 19

A single non-standard Ethernet from that allows for much larger maximum payload size is commonly referred to as jumbo frame.

Answer 19

True

Question 20

A type of Ethernet interface that automatically detects the required cable connection type (straight-through vs. crossover) and configures the connection appropriately is known as:

Answer 20

Auto MDI-X

Question 21

An Ethernet switch forwards LAN traffic from connected devices based on the information stored in:

Answer 21

MAC address table

Question 22

Answer 22

PoE
IEEE 802.3af

Question 23

Spanning Tree Protocol (STP) provides protection against:

Answer 23

Switching loops

Question 24

Which of the following standards implements PoE+?

Answer 24

Question 25

Which of the following allows for verifying the absence of traffic on a shared transmission medium in 802.3 networks?

Answer 25

CSMA/CD (Carrier-Sense Multiple Access with Collision Detection)

Question 26

A solution that allows to control access to a shared transmission medium in 802.11 networks is known as:

Answer 26

CSMS/CA (Carrier-Sense Multiple Access with Collision Avoidance)

Question 27
