firewall
network-based IDS (NIDS)
load balancer
software-based IDS (SIDS)
network-based IDS (NIDS)
Another name for port bonding is _____________?
port aggregation
proxy serving
port blocking
port mirroring
port aggregation

trunk port
DHCP relay
tag
agent
DHCP relay
Which term is synonymous with traffic shaping?
traffic routing
port blocking
bandwidth shaping
quality of servce routing
bandwidth shaping
A managed switch needs an IP Address to enable configuration on Layer 3?
True
False
True
Content switches designed to work with Web Servers can read incoming HTTP and HTTPS requests?
True
False
True
Which tool does Cisco use to implement DHCP relay?
Yost
relay agent
IP helper
BIND
IP helper
All of the cables from joined ports must go to the same device - another switch, a storage area, network (SAN), a station, etc…?
True
False
True
A managed switch needs an _________ to enable configuration on Layer 3?
segment ID
IP Address
port number
MAC Address
IP Address
The VLAN ID a trunk port associates untagged traffic with its _______ VLAN?
home
remote
local
native
native
Describe in-band and out-of-band management?
In-Band = When you configure a Switch over a Network, anyone who knows the IP Address of the managed device. Out-of-Band = When you connect a switch to a dedicated port to reduce risk that's totally separate from the rest of the Network which will prevent unauthorized access to those Ports.
How does DHCP manage IP Address assignment?
4 Step Process called the Four-Way Handshake, or DORA.
Discover, Offer, Request, and Acknowledgement.
At what layer of the OSI model do content switches operate? Describe the advantages they provide when working with Web Servers?
Content Switches work at Layer 7 (Application) of the OSI Model.
Designed to work with Web Serers to read incoming HTTP and HTTPS requests.
You can perform very advanced actions with this, such as handling TLS Certificates and Cookies, or removing the workload from the Web Servers - Load Balancing.
How does a multilayer switch work at Layer 2 or Layer 3?
Layer 2 Switch forwards traffic based on MAC Addresses.
Layer 3 Switch forwards traffic based on IP Address and is considered a Managed Switch or a “Layer 3 Capable Switch”.
A Layer 3 Switch is a Multilayer Switch because it can operate in both Layers.
Describe voice VLANs?
VLANs that are optimized for voice data streams and prioritize voice traffic over data traffic to ensure smooth communication.
Think of QoS but for voice stream.

remote

True
False
True
You can’t connect to a Managed Switch to tell it what you want it to do?
True
False
False
Every port starts with the default VLAN, VLAN1, so even if you don’t specify multiple VLANs, you get one by default?
True
False
True
Compare the two forms of Port Mirroring: Local and Remote?
Local - Copies data from one or more ports on a single switch to a specific port on that switch.
Remote - Enables you to access data copied from one or more specific ports on a switch without plugging directly into that switch.
How does IDS let the network administrators know if an attack is taking place?
At the very least the attack is logged, but some IDS offer a pop-up Alert message, email, or even a text message to your phone.

Carries all traffic, regardless of VLAN number, between all switches in a LAN.
