QUESTION 482

Which option is a core event publisher for EEM?

 

A.

Timer

B.

Policy Director

C.

Applet

D.

Script

 

Correct Answer: A

Explanation:

EEM is a flexible, policy-driven framework that supports in-box monitoring of different components of the system with the help of software agents known as event detectors. The figure below shows

the relationship between the EEM server, core event publishers (event detectors), and the event subscribers (policies). Basically, event publishers screen events and publish them when there is a

match on an event specification that is provided by the event subscriber. Event detectors notify the

EEM server when an event of interest occurs. The EEM policies that are configured using the Cisco command-line interface (CLI) then implement recovery on the basis of the current state of the system and the actions specified in the policy for the given event.

EEM offers the ability to monitor events and take informational or corrective action when the monitored events occur or when a threshold is reached. An EEM policy is an entity that defines an

event and the actions to be taken when that event occurs. There are two types of EEM policies: an applet or a script. An applet is a simple form of policy that is defined within the CLI configuration. A script is a form of policy that is written in Tool Command Language (Tcl).

QUESTION 485

Refer to the exhibit. Which option is the result of this configuration?

 

clip_image006

 

A.

Devices in OSPF area 15 can reach the summary route 192.168.0.0/16 and its more specific subnets.

B.

Devices in OSPF area 15 can reach only the more specific routes of 192.168.0.0/16.

C.

Devices in OSPF area 0 can reach the summary route 192.168.0.0/16 and its more specific subnets.

D.

Devices in OSPF area 0 can reach only the summary route of 192.168.0.0/16.

 

Correct Answer: A

Explanation:

To consolidate and summarize routes at an area boundary, use the area range command in router configuration mode. To disable this function, use theno form of this command.

area area-id range ip-address mask [advertise | not-advertise] [cost cost]

no area area-id range ip-address mask [advertise | not-advertise] [cost cost]

area-id

Identifier of the area about which routes are to be summarized. It can be specified as either a decimal value or as an IP address.

ip-address

IP address.

mask

IP address mask.

advertise

(Optional) Sets the address range status to advertise and generates a Type 3 summary link-state advertisement (LSA).

not-advertise

(Optional) Sets the address range status to DoNotAdvertise. The Type 3 summary LSA is suppressed, and the component networks remain hidden from other networks.

QUESTION 486

Which command enables L2 QoS support in all VLANs (including the native VLAN)?

 

A.

switchport priority extend cos

B.

mls qos trust dscp

C.

mls qos rewrite ip dscp

D.

switchport trunk native vlan tag

 

Correct Answer: D

Explanation:

You can enter the switchport trunk native vlan tag command to enable the tagging of native VLAN traffic on a per-port basis. When tagging is enabled, all the packets on the native VLAN are tagged and all incoming untagged data packets are dropped, but untagged control packets are accepted. When tagging is enabled, it will allow for L2 QoS support in all VLANs, including the native VLAN.
