QUESTION 61
Refer to the exhibit. Why is AS 65333 in parentheses?
A. It is an external AS.
B. It is a confederation AS.
C. It is the AS of a route reflector.
D. It is our own AS.
E. A route map has been applied to this route.
F. The BGP next hop is unreachable.
Answer: B
Explanation:
The AS numbers that are part of the confederation are grouped between parentheses and are replaced by the confederation identifier (the real AS number) in nonconfederation eBGP sessions. .
QUESTION 62
Refer to the exhibit. Which action would make the router the active VRRP router?
A. Recover interface Serial 1/0.
B. Increase priority in the configuration to 100.
C. Change the interface tracking priority to 100.
D. Recover interface Serial 1/1.
Answer: A
Explanation:
As VRRP Group 30 is configured with preemption all that is required is that the VRRP Priority be higher than that of the current active VRRP router and the current master router priority is 50.
QUESTION 63
Refer to the Exhibit. The displayed QoS configuration has been configured on a router.
IPv6 is being implemented on the router, and it is required to convert the QoS policy to support both IPv4 and IPv6 on the same class.
Which alternative configuration would allow matching DSCP AF41 for both IPv4 and IPv6 on the
same class map?
A. Class-map match-all CLASS1
Match dscp af41
B. Class-map match-all CLASS1
Match ip dscp af41
Match ipv6 dscp af41
C. Class-map match-any CLASS1
Match ip dscp af41
Match ipv6 dscp af41
D. Class-map match-any CLASS1
Match qos-group af41
Answer: A

B. Guarantee bandwidth during congestion to the voice class with a bandwidth command.
C. Increase the tx-ring of the egress interface.
D. Implement LLQ for the voice class.
E. Decrease the rx-ring of the egress interface.
F. Decrease the queue size of the voice class.

QUESTION 65
Refer to the exhibit. On what will the config class-map VOICE match?
A. only on UDP traffic between port ranges 16384 and 32767
B. only on DSCP EF traffic
C. on UDP traffic between port ranges 16384 and 32767, and on DSCP EF traffic
D. only on EF traffic that is UDP and within the UDP range of 16384 and 32767
Answer: C

QUESTION 66
Refer to the exhibit. Assuming that the routing protocol for this network is EIGRP, if the link between R1 and R3 failed, what would R4 receive from R3?
A. R4 would receive an update noting R3’s higher cost to reach 172.30.1.0/24.
B. R4 would not receive any updates or queries, since R3 would simply move to the path through R2.
C. R4 would receive a query, since R3 would mark 172.30.1.0/24 as active when the link between R1 and R4 failed.
D. R4 would not receive any packets, since R3 is not using the link to R1 to reach 172.30.1.0/24.
Answer: A
QUESTION 67
Which three statements accurately describe a link-state routing protocol? (Choose three.)
A. Each router sends routing information to all nodes in the flooding domain.
B. Each router sends all or some portion of its routing table to neighboring routers.
C. Each router individually builds a picture of the entire flooding domain.
D. Each router has knowledge of all other routers in the flooding domain.
E. Each router is only aware of neighboring routers.
F. Each router installs routes directly from the routing updates into the routing table.
Answer: ACD
QUESTION 68
Refer to the exhibit. What is true about the configuration in this exhibit?
A. It is an invalid configuration because it includes both an application layer match and and a
Layer 3 ACL.
B. It will create a class map that matches the content of ACL 101 and the HTTP protocol, and will
then create an inspection policy that will drop packets at the class map.
C. It will create a class map that matches the content of ACL 101 and the HTTP protocol, and will
then create an inspection policy that will allow packets at the class map.
D. It will create a class map that matches the content of ACL 101 or the HTTP protocol (depending
on the zone of the interface), and will then create an inspection policy that will drop packets at the
class map.
E. It will create a class map that matches the content of ACL 101 or the HTTP protocol (depending
on the zone of the interface), and will then create an inspection policy that will allow packets at the
class map.
F. It is an invalid configuration because the class map and policy map names must match.
Answer: B
Explanation:
Technically the syntax is incorrect as the application that is being inspected should be listed after the keyword type. However, this is not listed as one of the options. The correct configuration should be as follows:
class-map type inspect http match-all el
match access-group 101
policy-map type inspect http pl
class type inspect el drop
When multiple match criteria exist in the traffic class, you can identify evaluation instructions using the match any or match-all keywords. If you specify match-any as the evaluation instruction, the traffic being evaluated must match one of the specified criteria, typically match commands of the same type. If you specify match-all as the evaluation instruction, the traffic being evaluated must match all the specified criteria, typically match commands of different types.
Identifying Traffic in an Inspection Class Map
This type of class map allows you to match criteria that is specific to an application. For example, for DNS traffic, you can match the domain name in a DNS query. Note Not all applications support inspection class maps. See the CLI help for a list of supported applications. A class map groups multiple traffic matches (in a match-all class map), or lets you match any of a list of matches (in a match-any class map). The difference between creating a class map and defining the traffic match directly in the inspection policy map is that the class map lets you group multiple match commands, and you can reuse class maps. For the traffic that you identify in this class map, you can specify actions such as dropping, resetting, and/or logging the connection in the inspection policy map. If you want to perform different actions on different types of traffic, you should identify the traffic directly in the policy map. To define an inspection class map, perform the following steps:
Step 1 (Optional) If you want to match based on a regular expression, see the “Creating a Regular Expression” section and the “Creating a Regular Expression Class Map” section. Step 2 Create a class map by entering the following command:
hostname(config)# class-map type inspect application [match-all | match-any] class_map_name hostname(config-cmap)#

QUESTION 69
Refer to the exhibit. Users that are connected to switch SWD are complaining about slow performance when they are doing large file transfers from a server connected to switch SWB. All switches are running PVST+. Which option will improve the performance of the file transfers?
A. Reconnect the clients from switch SWD to switch SWA.
B. Reconnect the clients from switch SWD to switch SWC.
C. Change PVST+ to RSTP.
D. Change the STP root switch from switch SWA to switch SWB.
E. Configure an EtherChannel between switch SWB and switch SWC.
Answer: D
Explanation:
When SWA is the root bridge the traffic path will be SWD <-> SWC <-> SWA <-> SWB When SWB is the root bridge the traffic path will be SWD <-> SWC <-> SWB

B. VLAN 10 is not created in the switch database.
