SPOTTER NETWORK COMPREHENSIVE
EVALUATION 2026 QUESTIONS WITH
ANSWERS GRADED A+
●● Transport.
Answer: -The layer that creates a virtual circuit before transmitting
between two end stations
-This layer supports flow control and sequencing
●● Bridge or Switch.
Answer: -This device uses hardware addresses to filter a network
-This device creates many smaller collision domains, but the network is
still one large broadcast domain
●● Network.
Answer: Logical addressing is used at this layer
●● Data Link (Mac Sublayer).
Answer: Hardware addresses are defined at this layer
,●● Hub.
Answer: -This device creates one big collision domain and one large
broadcast domain
-a common connection point for devices in a network
-devices commonly used to connect segments of a LAN
-A network device used to connect several computers to a network.
Commonly used in a twisted-pair LAN. A cable runs from each
computer's NIC to the hub. The hub is often connected to a router.
-create one collision domain and one broadcast domain
-A physical star topology consists of several workstations that branch off
a central device
●● What advantage does a switch have over a hub?.
Answer: A switch recognizes frame boundaries and pays attention to the
destination MAC address of the incoming frame as well as the port on
which it was received.
●● Which device is used to segment a network?.
Answer: A switch.
,Hubs don't segment a network; they just connect network segments
together. Repeaters don't segment the network; they repeat a signal and
allow the distance covered to be increased.
●● Which of the following devices can work at both Layers 2 and 3 of
the OSI model?.
Answer: A switch is typically just a Layer 2 device segmenting the
network by using MAC addresses. However, some higher‐end switches
can provide Layer 3 services
●● What is an advantage of using DHCP in a network environment?.
Answer: Remember that DHCP servers assign IP addresses to hosts.
Thus DHCP allows easier administration than providing IP information
to each host by hand (called static IP addressing).
●● Which device should be used if you need to send incoming packets
to one or more machines that are hidden behind a single IP address?.
Answer: A load balancer uses a little trickery and sends incoming
packets to one or more machines that are hidden behind a single IP
address. Modern load-balancing routers can use different rules to make
decisions about where to route traffic, which can be based on least load,
fastest response times, or simply balancing requests.
●● What role does the "A" record in a Domain Name Service (DNS)
server have in your network?.
, Answer: DNS translates human names to IP addresses for routing your
packet through the Internet.
●● What is the most common use for a web proxy?.
Answer: Web cache, of course! Most proxy programs provide a means to
deny access to certain URLs in a blacklist, thus providing content
filtering, usually in corporate environments.
●● Which is not an advantage of network segmentation?.
Answer: The first 3 options all aid in boosting network performance, so
the only option left is broadcast storms. Increased traffic will increase
LAN congestion
●● Which device creates separate collision domains and a single
broadcast domain?.
Answer: Switches create separate collision domains, but a single
broadcast domain. Remember that routers provide a separate broadcast
domain for each interface.
●● Which device by default does not forward any broadcast or multicast
packets?.
Answer: Routers don't forward any broadcast or multicast packets by
default, but they do have plenty of other functions like using the logical
address, using access lists, and providing Layer 2 bridging functions.
