Question No: 1
A network engineer is notified that several employees are experiencing network performance related issues, and bandwidth-intensive applications are identified as the root cause. In order to identify which specific type of traffic is causing this slowness, information such as the source/destination IP and Layer 4 port numbers is required. Which feature should the engineer use to gather the required information?
A. SNMP
B. Cisco IOS EEM
C. NetFlow
D. Syslog
E. WCCP
Answer: C
Question No: 2

B. Flow-set marking in 1280-byte or larger packets is enabled.
C. IPv6 PMTU is enabled on the router.
D. IPv6 flow control is enabled on the router.
Answer: A

What type of route filtering is occurring on R6
A. Distribute-list using an ACL
B. Distribute-list using a prefix-list
C. Distribute-list using a route-map
D. An ACL using a distance of 255
Answer: A
Question No: 4
Which three route filtering statements are true? (Choose three)
A. After the router rip and passive-interface s0/0 commands have been issued, the s0/0
interface will not send any RIP updates, but will receive routing updates on that interface.
B. After the router eigrp 10 and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interface
C. After the router ospf 10 and passive-interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interface
D. When you use the passive-interface command with RIPv2, multicasts are sent out the specified interface
E. When you use the passive-interface command with EIGRP, hello messages are not sent out the specified interface
F. When you use the passive-interface command with OSPF, hello messages are not sent out the specified interface
Answer: A,E,F
Explanation:
Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface. However the command behavior varies from o ne protocol to anotheru201d
- In RIP, this command will not allow sending multicast updates via a specific interface but will allow listening to incoming updates from other RIP speaking neighbors. This means that the router will still be able to receive updates o n that passive interface and use them in its routing table.
In EIGRP and OSPF the passive-interface command stops sending outgoing hello packets, hence the router can not form any neighbor relationship via the passive interface. This behavior stops both outgoing and incoming routing updates.

C. Set the logging severity level to 1.
D. Specify a logging rate limit.
E. Disable event logging on all noncritical items.
Question No: 5

Answer: C
Question No: 6
Which two options are limitations of stateful NAT64? (Choose two)
A. It is unable to route VRF traffic.
B. IT is unable to route multicast traffic.
C. It supports FTP traffic only with an ALG.
D. It supports DNS64 only.
E. Layer 4 supports TCP only
Answer: B,E
Question No: 7
After you review the output of the command show ipv6 interface brief, you see that several IPv6 addresses have the 16-bit hexadecimal value of "FFFE" inserted into the address. Based on this information, what do you conclude about these IPv6 addresses?
A. IEEE EUI-64 was implemented when assigning IPv6 addresses on the device.
B. The addresses were misconfigured and will not function as intended.
C. IPv6 addresses containing "FFFE" indicate that the address is reserved for multicast.
D. The IPv6 universal/local flag (bit 7) was flipped.
E. IPv6 unicast forwarding was enabled, but IPv6 Cisco Express Forwarding was disabled.
Answer: A
Question No: 8
Refer to the exhibit.
In the network diagram, Area 1 is defined as a stub area. Because redistribution is not allowed in the stub area, EIGRP routes cannot be propagated into the OSPF domain. How does defining area 1 as a not-so-stubby area (NSSA) make it possible to inject EIGRP routes into the OSPF NSSA domain?
A. by creating type 5 LSAs
B. by creating type 7 LSAs
C. by creating a link between the EIGRP domain and the RIP domain, and redistributing EIGRP into RIP
D. by manually changing the routing metric of EIGRP so that it matches the routing metric of OSPF
Answer: B
Question No: 9

E. IT supports egress flows only.
F. It is IEEE standards based.
Answer: B,C
Question No: 10
