Routing & Switching Quiz Flashcards
Automatic routing table update is a feature of:
Dynamic routing
Which of the following answers refers to a link-state routing protocol?
OSPF (Open Shortest Path First)
Examples of distance-vector routing protocols include: (Select 2 answers)
EIGRP (Enhanced Interior Gateway Routing Protocol)
RIP (Routing Information Protocol)
Border Gateway Protocol (BGP) falls into the category of:
Hybrid routing protocols
A manually configured routing table entry is known as:
Static route
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.
True
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).
False
Which of the following is an exterior gateway protocol?
BGP (Border Gateway Protocol)
Which of the following answers refer(s) to (an) interior gateway protocol(s)? (Select all that apply)
RIP (Routing Information Protocol)
EIGRP(Enhanced Interior Gateway Routing Protocol)
OSPF (Open Shortest Path First)
A field in an IP datagram that specifies how many more hops a packet can travel before being discarded is called:
TTL (Time To Live)
Which of the following mechanisms can be used to prevent routing loops? (Select 2 answers)
Maximum hop count
Time to live (TTL)
Which of the following terms refer to solutions used for controlling network resources and assigning priority to different types of traffic? (Select 2 answers)
Packet shaping
Quality of Service (QoS)
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?
VLAN
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.
True
Which of the following solutions enables combining several physical ports of a switching device into a single logical channel?
LACP (Link Aggregation Control Protocol)
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.
True
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.
True
In the context of implementing secure network designs, the term “Port security” may aply to:
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_
A single non-standard Ethernet from that allows for much larger maximum payload size is commonly referred to as jumbo frame.
True
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:
Auto MDI-X
An Ethernet switch forwards LAN traffic from connected devices based on the information stored in:
MAC address table
A solution that allows to supply electricity over standard Ethernet cables is known as: (Select 2 answers)
PoE
IEEE 802.3af
Spanning Tree Protocol (STP) provides protection against:
Switching loops
Which of the following standards implements PoE+?
IEEE 802.3at
Which of the following allows for verifying the absence of traffic on a shared transmission medium in 802.3 networks?
CSMA/CD (Carrier-Sense Multiple Access with Collision Detection)
A solution that allows to control access to a shared transmission medium in 802.11 networks is known as:
CSMS/CA (Carrier-Sense Multiple Access with Collision Avoidance)
Address Resolution Protocol (ARP) provides what kind of resolution?
IP to MAC
Which IPv6 protocol is used by networked hosts to determine the link layer address in adjacent modes?
NDP (Neighbor Discovery Protocol)
An Ethernet switch table containing IP-to-MAC address mappings is called:
ARP (Address Resolution Protocol )Table
An IPv6 protocol performing the function of IPv4’s Address Resolution Protocol (ARP) is called:
NDP (Neighbor Discovery Protocol)
