QUESTION NO: 1
Which technology provides a secure communication channel for all traffic at Layer 2 of the OSI model?
A. IPsec
B. Cisco Trustsec
C. MACsec
D. SSL
Answer: C
Explanation:
MACsec, defined in 802.1AE, provides MAC-layer encryption over wired networks by using out- of
-band methods for encryption keying. The MACsec Key Agreement (MKA) Protocol provides the required session keys and manages the required encryption keys. MKA and MACsec are implemented after successful authentication using the 802.1x Extensible Authentication Protocol (EAP-TLS) or Pre
Shared Key (PSK) framework.
A switch using MACsec accepts either MACsec or non-MACsec frames, depending on the policy associated with the MKA peer. MACsec frames are encrypted and protected with an integrity check value (ICV). When the switch receives frames from the MKA peer, it decrypts them and calculates the correct ICV by using session keys provided by MKA. The switch compares that ICV to the ICV within the frame. If they are not identical, the frame is dropped. The switch also encrypts and adds an ICV to any frames sent over the secured port (the access point used to provide the secure MAC service to a
MKA peer) using the current session key.

Note: Cisco Trustsec is the solution which includes MACsec.
QUESTION NO: 2
To increase total throughput and redundancy on the links between the wireless controller and switch, the customer enabled LAG on the wireless controller.
Which EtherChannel mode must be configured on the switch to allow the WLC to connect?
A. Active
B. On
C. Auto
D. Passive
Answer: B
Explanation:
Restrictions for Link Aggregation:
You can bundle all eight ports on a Cisco 5508 Controller into a single link.
Terminating on two different modules within a single Catalyst 6500 series switch provides redundancy and ensures that connectivity between the switch and the controller is maintained when one module fails. The controller's port 1 is connected to Gigabit interface 3/1, and the controller's port 2 is connected to Gigabit interface 2/1 on the Catalyst 6500 series switch. Both switch ports are assigned to the same channel group.
LAG requires the EtherChannel to be configured for 'mode on' on both the controller and the Catalyst switch.
Once the EtherChannel is configured as on at both ends of the link, the Catalyst switch should not be configured for either Link Aggregation Control Protocol (LACP) or Cisco proprietary Port Aggregation
Protocol (PAgP) but be set unconditionally to LAG. Because no channel negotiation is done between the controller and the switch, the controller does not answer to negotiation frames and the LAG is not formed if a dynamic form of LAG is set on the switch. Additionally, LACP and PAgP are not supported on the controller.
If the recommended load-balancing method cannot be configured on the Catalyst switch, then configure the LAG connection as a single member link or disable LAG on the controller.

QUESTION NO: 3
Refer to the exhibit. A port channel is configured between SW2 and SW3. SW2 is not running a
Cisco operating system. When all physical connections are mode, the port channel does not establish.
Based on the configuration excerpt of SW3, what is the cause of the problem?
A. The port-channel interface lead balance should be set to src-mac
B. The port-channel trunk is not allowing the native VLAN.
C. The port-channel should be set to auto.
D. The port channel on SW2 is using an incompatible protocol.
Answer: D
Explanation:
The Cisco switch was configured with PAgP, which is a Cisco proprietary protocol so non-Cisco switch could not communicate.
QUESTION NO: 4
Which statement about multicast RPs is true?
A. RPs are required for protocol independent multicast sparse mode and dense mode.
B. By default, the RP is needed only to start new sessions with sources and receivers.
C. By default, the RP is needed periodically to maintain sessions with sources and receivers
D. RPs are required only when using protocol independent multicast dense mode.
Answer: B
Explanation:
A rendezvous point (RP) is required only in networks running Protocol Independent Multicast sparse mode (PIM-SM).
By default, the RP is needed only to start new sessions with sources and receivers.
Reference:
https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers/rps.html
For your information, in PIM-SM, only network segments with active receivers that have explicitly requested multicast data will be forwarded the traffic. This method of delivering multicast data is in contrast to the PIM dense mode (PIM-DM) model. In PIM-DM, multicast traffic is initially flooded to all segments of the network. Routers that have no downstream neighbors or directly connected receivers prune back the unwanted traffic.
QUESTION NO: 5
What is the difference between a RIB and a FIB?
A. The FIB is populated based on RIB content
B. The RIB is used to make IP source prefix-based switching decisions
C. The RIB maintains a mirror image of the FIB
D. The FIB is where all IP routing information is stored
Answer: A
Explanation:
CEF uses a Forwarding Information Base (FIB) to make IP destination prefix-based switching decisions.
The FIB is conceptually similar to a routing table or information base. It maintains a mirror image of the forwarding information contained in the IP routing table. When routing or topology changes occur in the network, the IP routing table is updated, and those changes are reflected in the FIB. The
FIB maintains next-hop address information based on the information in the IP routing table. Because there is a one-to-one correlation between FIB entries and routing table entries, the FIB contains all known routes and eliminates the need for route cache maintenance that is associated with earlier switching paths such as fast switching and optimum switching.
Note: In order to view the Routing information base (RIB) table, use the "show ip route" command.
To view the Forwarding Information Base (FIB), use the "show ip cef" command. RIB is in Control plane while FIB is in Data plane.
