Q401. Refer to the exhibit. 

What is wrong with the configuration of the tunnel interface of this DMVPN Phase II spoke router? 

A. The interface MTU is too high. 

B. The tunnel destination is missing. 

C. The NHRP NHS IP address is wrong. 

D. The tunnel mode is wrong. 



By default, tunnel interfaces use GRE as the tunnel mode, but a DMVPN router needs to be configured for GRE multipoint by using the “tunnel mode gre multipoint” interface command. 

Q402. Which three types of traffic are protected when you implement IPsec within an IPv6-in-IPv4 tunnel? (Choose three.) 

A. IPv6 link-local traffic 

B. IPv6 multicast traffic 

C. IPv6 unicast traffic 

D. IPv4 tunnel control traffic 

E. IPv4 broadcast traffic 

F. IPv6 broadcast traffic 

Answer: A,B,C 

Q403. Which statement about the VLAN database is true? 

A. Manually deleting the vlan.dat file can cause inconsistency in the database. 

B. Private VLAN information is stored in the database. 

C. VLAN configurations 1 through 4096 are stored in the vlan.dat file. 

D. The VLAN database is used only if the VTP domain name in the VLAN database matches the VTP domain name in the startup-config file. 


Q404. Refer to the exhibit. 

Notice that debug ip bgp updates have been enabled. What can you conclude from the debug output? 

A. This is the result of the clear ip bgp in command. 

B. This is the result of the clear ip bgp out command. 

C. BGP neighbor performed a graceful restart. 

D. BGP neighbor established a new BGP session. 



If you enter the clear ip bgp out command for a BGP peer, that router resends its BGP prefixes to that peer. This does not cause a change in the best path on the receiving BGP peer. Hence, there is no change in the Table Version on that peer. 

When you run the debug ip bgp updates on the receiving router, you see: 

BGP(0): rcvd UPDATE w/ attr: nexthop, origin i, metric 0, merged path 4, AS_PATH 

BGP(0): rcvd ignored 

The received update is recognized as a duplicate, so it is ignored and no best path change occurs.

Q405. Which standard feature can be exploited by an attacker to perform network reconnaissance? 

A. IP-directed broadcast 

B. maintenance operations protocol 

C. ICMP redirects 

D. source quench 


Q406. Refer to the exhibit. 

Which two statements about the R1 configuration are true? (Choose two.) 

A. The IP TTL value is copied to the MPLS field during label imposition. 

B. The structure of the MLPS network is hidden in a traceroute. 

C. The LDP session interval and hold times are configured for directly connected neighbors. 

D. R1 protects the session for 86400 seconds. 

E. All locally assigned labels are discarded. 

Answer: B,D 

Q407. Which two values must be identical to allow IS-IS devices to become neighbors? (Choose two.) 

A. interface MTU 

B. authentication key 


D. CLNS address 


F. area ID 

Answer: A,B 

Q408. Which three values can you use to configure an ERSPAN destination session? (Choose three.) 


B. source IP address 

C. destination IP address 

D. ID number 


F. session name 

Answer: B,D,E 


Drag and drop the method for refreshing BGP prefixes on the left to the corresponding description on the right. 


Q410. When the BGP additional-paths feature is used, what allows a BGP speaker to differentiate between the different available paths? 

A. The remote BGP peer prepends its own next-hop address to the prefix. 

B. A unique path identifier is encoded into a dedicated field to the NLRI. 

C. A route distinguisher is appended to the prefix by the receiving BGP speaker. 

D. The additional path information is encoded in an extended community.
