Q1. Which two methods can you use to limit the range for EIGRP queries? (Choose two.)
A. Use an access list to deny the multicast address 224.0.0.1 outbound from select EIGRP neighbor and permit everything else.
B. Configure route tagging for all EIGRP routes.
C. Summarize routes at the boundary routers of the EIGRP domain.
D. Configure unicast EIGRP on all routers in the EIGRP domain.
E. Configure stub routers in the EIGRP domain.
F. Use an access list to deny the multicast address 224.0.0.10 outbound from select EIGRP neighbors and permit everything else.
Answer: C,E
Q2. In an STP domain, which two statements are true for a nonroot switch, when it receives a configuration BPDU from the root bridge with the TC bit set? (Choose two.)
A. It sets the MAC table aging time to max_age time.
B. It sets the MAC table aging time to forward_delay time.
C. It recalculates the STP topology upon receiving topology change notification from the root switch.
D. It does not recalculate the STP topology upon receiving topology change notification from the root switch.
Answer: B,D
Q3. Refer to the exhibit.
Which AS paths are matched by this access list?
A. the origin AS 64496 only
B. the origin AS 64496 and any ASs after AS 64496
C. the directly attached AS 64496 and any ASs directly attached to AS 64496
D. the directly attached AS 64496 and any longer AS paths
Answer: C
Explanation:
If you want AS 1 to get networks originated from AS 4 and all directly attached ASs of AS 4, apply the following inbound filter on Router 1. ip as-path access-list 1 permit ^4_[0-9]*$ router bgp 1 neighbor 4.4.4.4 remote-as 4 neighbor 4.4.4.4 route-map foo in route-map foo permit 10 match as-path 1 In the ip as-path access-list command, the carat (^) starts the input string and designates "AS". The underscore (_) means there is a a null string in the string that follows "AS 4". The [0-9]* specifies that any connected AS with a valid AS number can pass the filter. The advantage of using the [0-9]* syntax is that it gives you the flexibility to add any number of ASs without modifying this command string.

Q4. Which three statements about OSPFv3 address families are true? (Choose three.)
A. Each address family requires the same instance ID.
B. Address families can perform route redistribution into any IPv4 routing protocol.
C. An address family can have two device processes on each interface.
D. IPv4 address family require an IPv4 address to be configured on the interface.
E. Each address family uses a different shortest path tree.
F. Different address families can share the same link state database.
Answer: B,D,E
Q5. Which two statements best describe the difference between active mode monitoring and passive mode monitoring? (Choose two.)
A. Passive mode monitoring uses IP SLA to generate probes for the purpose of obtaining information regarding the characteristics of the WAN links.
B. Active mode monitoring is the act of Cisco PfR gathering information on user packets assembled into flows by NetfFow.
C. Active mode monitoring uses IP SLA probes for obtaining performance characteristics of the current exit WAN link.
D. Passive mode monitoring uses NetFlow for obtaining performance characteristics of the exit WAN links.
Answer: C,D
Explanation:
. Passive and Active Monitoring
Passive monitoring is the act of OER gathering information on user packets assembled into flows by NetFlow. OER, when enabled, automatically enables NetFlow on the managed interfaces on the border routers. By aggregating this information on the border routers and periodically reporting the collected data to the master controller, the network prefixes and applications in use can automatically be learned. Additionally, attributes like throughput, reachability, loading, packet loss, and latency can be deduced from the collected flows. Active monitoring is the act of generating IP SLA probes to generate test traffic for the purpose of obtaining information regarding the characteristics of the WAN links. Active probes can either be implicitly generated by OER when passive monitoring has identified destination hosts, or explicitly configured by the network manager in the OER configuration.

Q6. Which two statements are true about OTV? (Choose two.)
A. It relies on flooding to propagate MAC address reachability information.
B. It uses a full mesh of point-to-multipoint tunnels to prevent head-end replication of multicast traffic.
C. It can work over any transport that can forward IP packets.
D. It supports automatic detection of multihoming.
Answer: C,D
Explanation:
The overlay nature of OTV allows it to work over any transport as long as this transport can forward IP packets. Any optimizations performed for IP in the transport will benefit the OTV encapsulated traffic. As part of the OTV control protocol, automatic detection of multihoming is included. This feature enables the multihoming of sites without requiring additional configuration or protocols

Q7. DRAG DROP
Drag and drop the IPv6 prefix on the left to the correct address type on the right.
Answer:
Q8. Which two statements about port ACLs are true? (Choose two.)
A. Port ACLs are supported on physical interfaces and are configured on a Layer 2 interface on a switch.
B. Port ACLs support both outbound and inbound traffic filtering.
C. When it is applied to trunk ports, the port ACL filters only native VLAN traffic.
D. When it is applied to a port with voice VLAN, the port ACL filters both voice and data VLAN traffic.
Answer: A,D
Explanation:
PACLs filter incoming traffic on Layer 2 interfaces, using Layer 3 information, Layer 4 header information, or non-IP Layer 2 information The port ACL (PACL) feature provides the ability to perform access control on specific Layer 2 ports. A Layer 2 port is a physical LAN or trunk port that belongs to a VLAN. Port ACLs perform access control on all traffic entering the specified Layer 2 port, including voice and data VLANs that may be configured on the port. Port ACLs are applied only on the ingress traffic.

Q9. Which two mechanisms provide Cisco IOS XE Software with control plane and data plane separation? (Choose two.)
A. Forwarding and Feature Manager
B. Forwarding Engine Driver
C. Forwarding Performance Management
D. Forwarding Information Base
Answer: A,B
Explanation:
Control Plane and Data Plane Separation
IOS XE introduces an opportunity to enable teams to now build drivers for new Data Plane ASICs outside the IOS instance and have them program to a set of standard APIs which in turn enforces Control Plane and Data Plane processing separation. IOS XE accomplishes Control Plane / Data Plane separation through the introduction of the Forwarding and Feature Manager (FFM) and its standard interface to the Forwarding Engine Driver (FED). FFM provides a set of APIs to Control Plane processes. In turn, the FFM programs the Data Plane via the FED and maintains forwarding state for the system. The FED is the instantiation of the hardware driver for the Data Plane and is provided by the platform.

Q10. What is the hop limit for an MLD message?
A. 1
B. 2
C. 15
D. 255
Answer: A
Explanation:
MLD uses the Internet Control Message Protocol (ICMP) to carry its messages. All MLD messages are link-local with a hop limit of 1, and they all have the alert option set. The alert option implies an implementation of the hop-by-hop option header.
