350-001 Routing & Switching .

Day 1, May 23, .

Q1, In order to maintain security, with which hop count are IPv6 neighbor discovery packets sent?
[A]A suggestion (RFC 3682) of using a "hop count of 255" has only rather limited value.

 Q2, Which command will define a VRF with name 'CCIE' in IPv6?
 [A] vrf definition CCIE

 Q3, LDP advertise which route?
 [A] IGP

 Q4, Which command can be used on a PE router to connect to a CE router (11.1.1.4) in VRF red?
[A] telnet 11.1.1.4 /vrf red

 Q5, The routing inside the VPN RED will work without any special OSPF configuration

 Q6, Which two statements are correct about Nonstop Forwarding? (Choose two.)
[A] B. It is a Layer 3 function that works with SSO to minimize the amount of time a network is unavailable to users following a switchover
E. The main objective of NSF is to continue forwarding IP packets following a switchover SSO=> stateful switchover

 Q7, Which three fields are optional in an OSPFv3 external LSA? (Choose three.)
 [A] A. Forwarding Address B. External Route C. Reference Link-State ID

 Q8, On a router, interface S0 is running EIGRPv6, and interface S1 is running OSPFv3. A redistribution command is issued under OSPFv3, redistribute EIGRP 1 metric 20 under ipv6 router nospf 1. What will happen after applying this redistribution command?
[A] All routes showing up as D and D EX in the routing table will be redistributed into OSPFv3.

 Q9, Which type of domains is interconnected using Multicast Source Discovery Protocol?
[A] PIM-SM 

Q10, Which two multicast address ranges are assigned as source-specific multicast destination addresses and are reserved for use by source-specific applications and protocols? (Choose two.)
[A] 232.0.0.0/8 and FF3x::/32

 Q11, How is RPF used in multicast routing?
[A] to prevent multicast packets from looping and to instruct PIM where to send a (*,G) or (S,G) join message

 Q12, What does the incoming interface of the above (*,G) entry indicate?
 [A] the interface closest to the RP, according to the unicast routing table

 Q13, Which interface(s) will show ip rpf 1.1.1.2 indicate as RPF interface(s)
[A] ethernet 1/0

 Q14, Apart from interdomain multicast routing, what else is MSDP used for?
[A] anycast RP

 Q15, Which IGMPv2 message contains a non-zero "Max Response Time"?
A. Membership Query

 Q16, Which IGMPv2 message is displayed in the output of the packet capture?
B. Membership Report 

Q17, What is Phantom RP used for?
B. it is used for redundancy in bidirectional PIM

 Q18, Which three statements are true about TACACS+? (Choose three.)
A. It is a Cisco proprietary protocol. C. Authentication and authorization are done at different stages. D. TACACS+ encrypts the entire body of the packet, but leaves a standard TACACS+ header.

 Q19, Which two statements are correct? (Choose two.)
B. The access list has logging enabled. D. The command ip access-list logging hash-generation is enabled

 Q20, C. NTP is not configured on the router.



Q21, What does Cisco recommend when you are enabling Cisco IOS IPS?
A. Do not enable all the signatures at the same time

Q22, B. OSPF peers are using Type 2 authentication. (MD auth)

Q23, Which two statements are true about Unicast Reverse Path Forwarding Loose Mode? (Choose two.)
A. It is used in multihome network scenarios.
B. It can be used with BGP to mitigate DoS and DDoS.


Q24, ##aaa authentication login default group tacacs+ none.
D. If the TACACS+ server failed, no authentication would be required

Q25, Which three protocols should be explicitly managed by using a CoPP policy on an Internet border router? (Choose three.)
B. ICMP
C. BGP
D. SSH

Q26, What is true about IP Source Guard with port security?
C. The DHCP server must support option 82, or the client is not assigned an IP address
