Q271. When you implement CoPP on your network, what is its default action?
A. permit all traffic
B. rate-limit bidirectional traffic to the control plane
C. drop management ingress traffic to the control plane
D. monitor ingress and egress traffic to the control plane by using access groups that are applied to the interface
E. block all traffic
Answer: A
Q272. DRAG DROP
Drag and drop the fragmentation characteristics on the left to the corresponding protocol on the right.
Answer:
Q273. Which statement describes the native VLAN concept in an ISL trunk?
A. It is the VLAN ID that is assigned to untagged packets.
B. It is the VLAN with highest priority.
C. It is the default VLAN for a trunk.
D. There is no native VLAN concept in an ISL trunk.
Answer: D
Explanation:
ISL has no native VLAN concept because it places the entire Ethernet frame in the payload of an ISL frame. Native VLANs is an 802.1Q specific concept
Q274. Refer to the exhibit.
Assuming that the peer is configured correctly and the interface is up, how many neighbors will be seen in the EIGRPv6 neighbor table on this IPv6-only router?
A. one neighbor, which will use a local router-id of 6010. AB8. . /64
B. one neighbor, which will use a local router-id of 6020. AB8. . /64
C. none, because EIGRPv6 only supports authenticated peers
D. none, because of the mismatch of timers
E. none, because there is no EIGRP router ID configured
Answer: E
Explanation:
Configuring EIGRP for IPv6 has some restrictions; they are listed below:
. The interfaces can be directly configured with EIGRP for IPv6, without the use of a global IPv6 address. There is no network statement in EIGRP for IPv6.
. The router ID needs to be configured for an EIGRPv6 protocol instance before it can run.
. EIGRP for IPv6 has a shutdown feature. Ensure that the routing process is in "no shut" mode to start running the protocol.

Q275. DRAG DROP
Drag each IS-IS command on the left to its effect on the right.
Answer:
Q276. Which three statements are true about PPP CHAP authentication? (Choose three.)
A. PPP encapsulation must be enabled globally.
B. The LCP phase must be complete and in closed state.
C. The hostname used by a router for CHAP authentication cannot be changed.
D. PPP encapsulation must be enabled on the interface.
E. The LCP phase must be complete and in open state.
F. By default, the router uses its hostname to identify itself to the peer.
Answer: D,E,F
Explanation:
Point-to-Point Protocol (PPP) authentication issues are one of the most common causes for dialup link failures. This document provides some troubleshooting procedures for PPP authentication issues.
Prerequisites
. Enable PPP encapsulation
. The PPP authentication phase does not begin until the Link Control Protocol (LCP) phase is complete and is in the open state. If debug ppp negotiation does not indicate that LCP is open, troubleshoot this issue before proceeding.
Note. By default, the router uses its hostname to identify itself to the peer. However, this CHAP username can be changed through the ppp chap hostname command.

Q277. Which statement describes the difference between a stub area and a totally stub area?
A. The ABR advertises a default route to a totally stub area and not to a stub area.
B. Stub areas do not allow LSA types 4 and 5, while totally stub areas do not allow LSA types 3, 4, and 5.
C. Totally stub areas allow limited external routes in the area via a special type 7 LSA, while stub areas do not.
D. Stub areas do not allow external LSAs, ASBR summary LSAs, or summary LSAs with the exception of a default route originated by the ABR via a summary LSA.
Answer: B
Explanation:
. Standard areas can contain LSAs of type 1, 2, 3, 4, and 5, and may contain an ASBR. The backbone is considered a standard area.
. Stub areas can contain type 1, 2, and 3 LSAs. A default route is substituted for external routes.
. Totally stubby areas can only contain type 1 and 2 LSAs, and a single type 3 LSA. The type 3 LSA describes a default route, substituted for all external and inter-area routes.
. Not-so-stubby areas implement stub or totally stubby functionality yet contain an ASBR. Type 7 LSAs generated by the ASBR are converted to type 5 by ABRs to be flooded to the rest of the OSPF domain.

Q278. Which two services are used to transport Layer 2 frames across a packet-switched network? (Choose two.)
A. Frame Relay
B. ATM
C. AToM
D. L2TPv3
Answer: C,D
Explanation:
Both AToM and L2TPv3 have the common objective of transmitting packet switched traffic of L2 frames (Frame Relay, ATM, and Ethernet) across a packet-switched network.

Q279. Which three statements about the differences between Cisco IOS and IOS-XE functionality are true? (Choose three.)
A. Only IOS-XE Software can host applications outside of the IOS context.
B. Only the IOS-XE Services Plane has multiple cores.
C. Only the IOS-XE Data Plane has multiple cores.
D. Only the IOS-XE Control Plane has multiple cores.
E. Only IOS-XE module management integrates with packet processing.
F. Only IOS-XE configuration and control is integrated with the kernel.
Answer: A,B,C
Q280. Which three statements about SPAN traffic monitoring are true? (Choose three.)
A. Traffic from a non-source VLAN is discarded when it arrives on a source VLAN.
B. Multiple sessions can send traffic to an individual destination port.
C. It supports up to 32 SPAN ports per switch.
D. The destination port acts as a normal switchport.
E. It supports up to 64 SPAN ports per switch.
F. Only one session can send traffic to an individual destination port.
Answer: A,E,F
Explanation:
You can create up to a total of 64 SPAN and ERSPAN sessions to define sources and destinations on the local device.You can also create a SPAN session to monitor multiple VLAN sources and choose only VLANs of interest to transmit on multiple destination ports.
For example, you can configure SPAN on a trunk port and monitor traffic from different VLANs on different destination ports.
You can configure a particular destination port in only one SPAN session.
Traffic from a non-source VLAN is discarded when it arrives on a source VLAN.
