QUESTION NO: 1
Which feature does Cisco TrustSec use to provide scalable, secure communication throughout a network?
A. security group tag number assigned to each user on a switch
B. security group tag ACL assigned to each router on a network
C. security group tag ACL assigned to each port on a switch
D. security group tag number assigned to each port on a network
Answer: D
Explanation:
Cisco TrustSec uses tags to represent logical group privilege. This tag, called a Security Group Tag
(SGT), is used in access policies. The SGT is understood and is used to enforce traffic by Cisco switches, routers and firewalls . Cisco TrustSec is defined in three phases: classification, propagation and enforcement.
When users and devices connect to a network, the network assigns a specific security group.
This process is called classification. Classification can be based on the results of the authentication or by associating the SGT with an IP, VLAN, or port-profile (-> Answer A and answer C are not correct as they say "assigned ... on a switch" only. Answer D is not correct either as it says "assigned to each router").
QUESTION NO: 2
Which statement about a fabric access point is true?
A. It is in local mode an must connected directly to the fabric edge switch.
B. It is in FlexConnect mode and must be connected directly to the fabric edge switch.
C. It is in FlexConnect mode and must be connected directly to the fabric border node.
D. It is in local mode an must be connected directly to the fabric border node.
Answer: A
Explanation:
Fabric mode APs continue to support the same wireless media services that traditional APs support; apply AVC, quality of service (QoS), and other wireless policies; and establish the CAPWAP control plane to the fabric WLC. Fabric APs join as local-mode APs and must be directly connected to the fabric edge node switch to enable fabric registration events, including RLOC assignment via the fabric
WLC. The fabric edge nodes use CDP to recognize APs as special wired hosts, applying special port configurations and assigning the APs to a unique overlay network within a common EID space across a fabric. The assignment allows management simplification by using a single subnet to cover the AP infrastructure at a fabric site.

QUESTION NO: 3
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.
QUESTION NO: 4
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: 5
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.
