Q62. Which two statements about PBR route maps are true? (Choose two.)
A. They can use extended ACLs to identify traffic.
B. They can route unicast traffic without interface-level classification.
C. They can be applied to both ingress and egress traffic.
D. They can classify traffic based on prefix-lists.
E. They can set the metric and IP precedence bits.
Answer: A,B
Q63. Which two features are used for inspection when IPv6 address glean is enabled? (Choose two.)
A. DHCP messages
B. ND messages
C. ICMPv6 messages
D. UDP messages
E. TCP messages
Answer: A,B
Explanation:
IPv6 address glean is the foundation for many other IPv6 features that depend on an accurate binding table. It inspects ND and DHCP messages on a link to glean addresses, and then populates the binding table with these addresses. This feature also enforces address ownership and limits the number of addresses any given node is allowed to claim.

Q64. Which three options are components of an EEM CLI policy? (Choose three.)
A. Safe-Tcl
B. applet name
C. Fast Tcl
D. event
E. action
F. Tcl bytecode
Answer: B,D,E
Explanation:
The Embedded Event Manager (EEM) monitors events that occur on your device and takes action to recover or troubleshoot these events, based on your configuration.
EEM consists of three major components:
Event statements — Events to monitor from another Cisco NX-OS component that might require some action, workaround, or notification.
Action statements — An action that EEM can take, such as sending an e-mail, or disabling an interface, to recover from an event.
Policies — An applet name paired with one or more actions to troubleshoot or recover from the event.

Q65. Which two statements about MAC Authentication Bypass are true? (Choose two.)
A. Traffic from an endpoint is authorized to pass after MAB authenticates the MAC address of the endpoint.
B. During the learning stage, the switch examines multiple packets from the endpoint to determine the MAC address of the endpoint.
C. After the switch learns the MAC address of the endpoint, it uses TACACS+ to authenticate it.
D. After learning a source MAC address, it sends the host a RADIUS Account-Request message to validate the address.
E. The MAC address of a device serves as its user name and password to authenticate with a RADIUS server.
Answer: A,E
Q66. Refer to the exhibit.
Which statement is true?
A. 2001:DB8::1/128 is a local host route, and it can be redistributed into a dynamic routing protocol.
B. 2001:DB8::1/128 is a local host route, and it cannot be redistributed into a dynamic routing protocol.
C. 2001:DB8::1/128 is a local host route that was created because ipv6 unicast-routing is not enabled on this router.
D. 2001:DB8::1/128 is a route that was put in the IPv6 routing table because one of this router's loopback interfaces has the IPv6 address 2001:DB8::1/128.
Answer: B
Explanation:
The local routes have the administrative distance of 0. This is the same adminstrative distance as connected routes. However, when you configure redistributed connected under any routing process, the connected routes are redistributed, but the local routes are not. This behavior allows the networks to not require a large number of host routes, because the networks of the interfaces are advertised with their proper masks. These host routes are only needed on the router that owns the IP address in order to process packets destined to that IP address.
It is normal for local host routes to be listed in the IPv4 and IPv6 routing table for IP addresses of the router's interfaces. Their purpose is to create a corresponding CEF entry as a receive entry so that the packets destined to this IP address can be processed by the router itself. These routes cannot be redistributed into any routing protocol.

Q70. Refer to the exhibit.
Which statement about configuring the switch to manage traffic is true?
A. The switchport priority extend cos command on interface FastEthernet0/0 prevents traffic to and from the PC from taking advantage of the high-priority data queue that is assigned to the IP phone.
B. The switchport priority extend cos command on interface FastEthernet0/0 enables traffic to and from the PC to use the high priority data queue that is assigned to the IP phone.
C. When the switch is configured to trust the CoS label of incoming traffic, the trusted boundary feature is disabled automatically.
D. The mls qos cos override command on interface FastEthernet0/0 configures the port to trust the CoS label of traffic to and from the PC.
Answer: A
Explanation:
In some situations, you can prevent a PC connected to the Cisco IP Phone from taking advantage of a high-priority data queue. You can use the switchport priority extend cos interface configuration command to configure the telephone through the switch CLI to override the priority of the traffic received from the PC.
