Q136. - (Topic 1)
Which two characteristics apply to Layer 2 switches? (Choose two.)
A. Increases the number of collision domains
B. Decreases the number of collision domains
C. Implements VLAN
D. Decreases the number of broadcast domains
E. Uses the IP address to make decisions for forwarding data packets
Answer: A,C
Explanation:
Layer 2 switches offer a number of benefits to hubs, such as the use of VLANs and each switch port is in its own separate collision domain, thus eliminating collisions on the segment.
Q137. - (Topic 3)
Which two of these statements are true of IPv6 address representation? (Choose two.)
A. There are four types of IPv6 addresses: unicast, multicast, anycast, and broadcast.
B. A single interface may be assigned multiple IPv6 addresses of any type.
C. Every IPv6 interface contains at least one loopback address.
D. The first 64 bits represent the dynamically created interface ID.
E. Leading zeros in an IPv6 16 bit hexadecimal field are mandatory.
Answer: B,C
Explanation:
A single interface may be assigned multiple addresses of any type (unicast, anycast,
multicast).
Every IPv6-enabled interface must contain at least one loopback and one link-local
address.
Optionally, every interface can have multiple unique local and global addresses.
IPv6 host addresses can be assigned in multiple ways:
Static configuration
Stateless autoconfiguration
DHCPv6
When IPv6 is used over Ethernet networks, the Ethernet MAC address can be used to
generate the 64-bit interface ID for the host. This is called the EUI-64 address.
Since MAC addresses use 48 bits, additional bits must be inserted to fill the 64 bits
required.

Q138. - (Topic 5)
Which of the following is true regarding the configuration of SwitchA?
A. only 5 simultaneous remote connections are possible
B. remote connections using ssh will require a username and password
C. only connections from the local network will be possible
D. console access to SwitchA requires a password
Answer: B
Q139. - (Topic 3)
Which one of the following IP addresses is the last valid host in the subnet using mask 255.255.255.224?
A. 192.168.2.63
B. 192.168.2.62
C. 192.168.2.61
D. 192.168.2.60
E. 192.168.2.32
Answer: B
Explanation:
With the 224 there are 8 networks with increments of 32 One of these is 32 33 62 63 where 63 is broadcast so 62 is last valid host out of given choices.
Q140. - (Topic 3)
Which router command will configure an interface with the IP address 10.10.80.1/19?
A. router(config-if)# ip address 10.10.80.1/19
B. router(config-if)# ip address 10.10.80.1 255.255.0.0
C. router(config-if)# ip address 10.10.80.1 255.255.255.0
D. router(config-if)# ip address 10.10.80.1 255.255.224.0
E. router(config-if)# ip address 10.10.80.1 255.255.240.0
F. router(config-if)# ip address 10.10.80.1 255.255.255.240
Answer: D
Explanation:
255.255.224 equal /19 in CIDR format hence the answer
Q141. - (Topic 3)
Refer to the exhibit.
Which default gateway address should be assigned to HostA?
A. 192.168.1.1
B. 192.168.1.65
C. 192.168.1.66
D. 192.168.1.129
E. 10.1.1.1
F. 10.1.1.2
Answer: B
Explanation:
The default gateway will be the IP address of the router that it connects to, not the switch.
Q142. - (Topic 3)
Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.)
Router(config)# router ospf 1
A. All OSPF routers in an area must have the same process ID.
B. Only one process number can be used on the same router.
C. Different process identifiers can be used to run multiple OSPF processes
D. The process number can be any number from 1 to 65,535.
E. Hello packets are sent to each neighbor to determine the processor identifier.
Answer: C,D
Explanation:
Multiple OSPF processes can be configured on a router using multiple process ID’s.
The valid process ID’s are shown below: Edge-B(config)#router ospf <1-65535> Process ID
