LAG (Link Aggregation Group)
WLCs only support ____ mode LAGs
Static, no PAgP or LACP
Which DHCP option can be configured to tell an AP the IP address of its WLC?
DHCP option 43
WLC interfaces are _____ interfaces
a) Logical
b) Physical
a) Logical
Like an SVI
What are the types of ports a WLC can have?
- Service Port
- Distribution System Ports
- Console Port
- Redundancy Port
A WLC Service Port is used for what?
Used for out-of-band management. Must connect to a switch access port.
A WLC Distribution System Port is used for what?
Used for data traffic. Usually a switch trunk port, or a LAG
What is a WLC Redundancy port?
Used to connect to another WLC to form a high availability pair
What are the types of interfaces a WLC can have?
- Management interface (SSH, CAPWAP)
- Redundancy Management (WLC to WLC comms)
- Virtual interface (relaying DHCP, etc)
- Service port interface
- Dynamic interface (map a WLAN to a VLAN)
When configuring a WLAN using a WLC GUI, what menu would you use to map the new WLAN to an interface?
General menu
When creating a WLAN using a WLC GUI, is the WLAN enabled by default?
No, you have to ensure that you check the enabled box in the general menu
Does a WLC have a setup wizard?
Yes
What feature of Cisco APs allows for the automatic determination of wireless channel and transmit strength?
Auto-RF
What are the types of WLC ports?
- Service (management)
- Distribution system
- Console
- Redundancy (for forming HA WLC pairs)
Household WiFi uses _____ for authentication key management
PSK
Describe the L3 web authentication security policy
After a client gets an IP and tries to access a web page, they will have to enter a username and password to authenticate
Describe the L3 web passthrough security policy
After the client gets an IP and tries to access a web page, a warning/statement is displayed and the client simply has to agree to gain internet access
Describe the L3 conditional web redirect security policy
Similar to web auth/ web passthrough, but requires 802.1x L2 authentication
Describe the L3 splash page web redirect security policy
Similar to web auth / web passthrough, but requires 802.1x L2 authenticaiton
What WLC GUI tab would you use to view SNMP and Syslog statuses and configuration?
Management tab
What type of ACL is used to restrict access to WLC management?
CPU ACL
Which WLC port can be used to form an HA pair with another WLC?
a) Distribution system port
b) Redundancy port
c) High Availability port
d) Service port
b) Redundancy port
Which WLC interface maps a WLAN to a VLAN?
a) Dynamic interface
b) Virtual interface
c) Distribution system interface
d) Service port interface
a) Dynamic interface
Which of the following is a type of L3 authentication?
a) 802.1x
b) WPA/WPA2
c) Static WEP
d) Web Authentication
d) Web authentication
Which WLC QoS setting should be used for video traffic?
a) Platinum
b) Gold
c) Silver
d) Bronze
b) Gold
Which WLC port type can form a LAG to pass standard data traffic?
a) LAG port
b) Distribution system port
c) Service port
d) Console port
b) Distribution system port
Which WLC interface controls all L3 communications between a WLC and a lightweight AP?
c) AP-Manager interface
If one or more links, but not all, fail on a LAG connected to a WLC, how will client traffic be impacted?
All client traffic will still be forwarded. Just because the LAG has port failures, traffic doesn’t get sent intermittently or not at all. As long as one port in the LAG is still functional, traffic can still traverse it
