NEW QUESTION 7

A technician, Joe, has been tasked with assigning two IP addresses to WAN interfaces on connected routers. In order to conserve address space, which of the following subnet masks should Joe use for this subnet?

• A. /24
• B. /32
• C. /28
• D. /29
• E. /30

Answer: E

Explanation:
An IPv4 addressconsists of 32 bits. The first x number of bits in the address is the network address and the remaining bits are used for the host addresses. The subnet mask defines how many bits form the network address and from that, we can calculate how many bits are used for the host addresses.
In this question, the /30 subnet mask dictates that the first 30 bits of the IP address are used for network addressing and the remaining 2 bits are used for host addressing. The formula to calculate the number of hosts in a subnet is 2n - 2. The "n" in the host's formula represents the number of bits used for host addressing. If we apply the formula (22 – 2), a/30 subnet mask will provide 2 IP addresses.

NEW QUESTION 13

A network technician is attempting to connect a new host to existing manufacturing equipment on an Ethernet network. The technician is having issues trying to establish communication between the old equipment and the new host. The technician checks the cabling for breaks and finds that the CAT3 cable in use is in perfect condition. Which of the following should the technician check to ensure the new host will connect?

• A. Confirm the new host is using 10GBaseSR due to the manufacturing environment
• B. Confirm the new host is compatible with 10BaseT Ethernet
• C. Confirm the existing 10Base2 equipment is using the proper frame type
• D. Confirm that CSMA/CD is disabled on the Ethernet network

Answer: B

Explanation:
The question states that the equipment is old and that CAT3 cabling is being used. 10BaseT Ethernet networks are old and slow by today’s standards. 10BaseT Ethernet networks use CAT3 UTP cabling and offer a maximum bandwidth of just 10Mpbs.
A new host computer nowadays will have a network card that supports 1000Mpbs to be used with CAT5, CAT5e or CAT6 network cables in a 1000BaseT network. In this question, we need to check that the network card on thenew host computer is backward-compatible with the old 10BaseT network.

NEW QUESTION 17

Which of the following devices implements CSMA/CA virtually through the RTS/CTS protocols?

• A. Firewall
• B. Router
• C. 802.11 AP
• D. Switch

Answer: C

Explanation:
802.11 AP is a Wireless Access Point used in a wireless network.
If two computers on a network send data frames at thesame time, a collision between the frames can occur. The frames are then discarded and the sending computers will attempt to send the data again.
Carrier sense multiple access with collision avoidance (CSMA/CA) is a protocol used in wireless networks wherecomputers connected to the wireless network attempt to avoid collisions by transmitting data only when the channel is sensed to be "idle". Carrier Sense Multiple Access/Collision Detect (CSMA/CD) is unreliable in wireless networks because computers connected to the wireless network often cannot see each other so CSMA/CA is a better option for avoiding collisions.
Request to Send/Clear to Send (RTS/CTS) can also be used to mediate access to the wireless network. This goes some way to alleviating the problemof computers not being able to see each other because in a wireless network, the Wireless Access Point only issues a “Clear to Send” to one node at a time.
With RTS/CTS, a Request to Send (RTS) packet is sent by the sending computer, and a Clear to Send(CTS) packet is sent by the intended receiver. This will alert all computers within range of the sender, receiver or both, to not transmit for the duration of the transmission. This is known as the IEEE 802.11 RTS/CTS exchange.
