Q31. - (Topic 5)
The network administrator has been asked to give reasons for moving from IPv4 to IPv6. What are two valid reasons for adopting IPv6 over IPv4? (Choose two.)
A. no broadcast
B. change of source address in the IPv6 header
C. change of destination address in the IPv6 header
D. Telnet access does not require a password
E. autoconfiguration
F. NAT
Answer: A,E
Explanation:
IPv6 does not use broadcasts, and autoconfiguration is a feature of IPV6 that allows for hosts to automatically obtain an IPv6 address.
Q32. - (Topic 5)
Which statement describes VRRP object tracking?
A. It monitors traffic flow and link utilization.
B. It ensures the best VRRP router is the virtual router master for the group.
C. It causes traffic to dynamically move to higher bandwidth links.
D. It thwarts man-in-the-middle attacks.
Answer: B
Explanation:
Object tracking is the process of tracking the state of a configured object and uses that state to determine the priority of the VRRP router in a VRRP group.
Q33. - (Topic 6)
Refer to the exhibit.
Statements A, B, C, and D of ACL 10 have been entered in the shown order and applied to interface E0 inbound, to prevent all hosts (except those whose addresses are the first and last IP of subnet 172.21.1.128/28) from accessing the network. But as is, the ACL does not restrict anyone from the network. How can the ACL statements be re-arranged so that the system works as intended?
A. ACDB
B. BADC
C. DBAC
D. CDBA
Answer: D
Explanation:
Routers go line by line through an access list until a match is found and then will not look any further, even if a more specific of better match is found later on in the access list. So, it it best to begin with the most specific entries first, in this cast the two hosts in line C and D. Then, include the subnet (B) and then finally the rest of the traffic (A).
Q34. - (Topic 8)
Which condition does the err-disabled status indicate on an Ethernet interface?
A. There is a duplex mismatch.
B. The device at the other end of the connection is powered off.
C. The serial interface is disabled.
D. The interface is configured with the shutdown command.
E. Port security has disabled the interface.
F. The interface is fully functioning.
Answer: E
Q35. - (Topic 4)
Which PPP subprotocol negotiates authentication options?
A. NCP
B. ISDN
C. SLIP
D. LCP
E. DLCI
Answer: D
Explanation:
The PPP Link Control Protocol (LCP) is documented in RFC 1661. LPC negotiates link and PPP parameters to dynamically configure the data link layer of a PPP connection. Common LCP options include the PPP MRU, the authentication protocol, compression of PPP header fields, callback, and multilink options.
Q36. - (Topic 8)
On which type of device is every port in the same collision domain?
A. a router
B. a Layer 2 switch
C. a hub
Answer: C
Explanation: Collision domainA collision domain is, as the name implies, a part of a
network where packet collisions can occur. A collision occurs when two devices send a packet at the same time on the shared network segment. The packets collide and both devices must send the packets again, which reduces network efficiency. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.
Q37. - (Topic 3)
What are two enhancements that OSPFv3 supports over OSPFv2? (Choose two.)
A. It requires the use of ARP.
B. It can support multiple IPv6 subnets on a single link.
C. It supports up to 2 instances of OSPFv3 over a common link.
D. It routes over links rather than over networks.
Answer: B,D
Explanation:
Here is a list of the differences between OSPFv2 and OSPFv3:
✑ They use different address families (OSPFv2 is for IPv4-only, OSPFv3 can be used for IPv6-only or both protocols
✑ OSPFv3 introduces new LSA types
✑ OSPFv3 has different packet format
✑ OSPFv3 uses different flooding scope bits (U/S2/S1)
✑ OSPFv3 adjacencies are formed over link-local IPv6 communications
✑ OSPFv3 runs per-link rather than per-subnet
✑ OSPFv3 supports multiple instances on a single link, Interfaces can have multiple IPv6 addresses
✑ OSPFv3 uses multicast addresses FF02::5 (all OSPF routers), FF02::6 (all OSPF DRs)
✑ OSPFv3 Neighbor Authentication done with IPsec (AH)
✑ OSPFv2 Router ID (RID) must be manually configured, still a 32-bit number

Q38. - (Topic 3)
Refer to the exhibit.
Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?
A. 10.1.1.2
B. 10.154.154.1
C. 172.16.5.1
D. 192.168.5.3
Answer: C
Explanation:
The highest IP address of all loopback interfaces will be chosen -> Loopback 0 will be chosen as the router ID.
Q39. - (Topic 8)
Which IPV6 function serves the same purpose as ARP entry verification on an IPv4 network?
A. interface ip address verification.
B. MAC address table verification
C. neighbor discovery verification
D. routing table entry verification
Answer: C
Q40. DRAG DROP - (Topic 4)
Drag the Frame Relay acronym on the left to match its definition on the right. (Not all acronyms are used.)
Answer:
