Question 1

How many nibbles are in a /40 prefix?
A)10
B)40
C)16
D)5

Accepted Answer

A /40 prefix means 40 bits. Since a nibble consists of 4 bits, dividing 40 by 4 gives us 10 nibbles.

Question 2

What will the status of the M and O flags be in the RA-ICMP field if a combination of SLAAC and DHCPv6 are being used?
A)0, 0
B)0, 1
C)1, 0
D)1, 1

Accepted Answer

When a combination of SLAAC (Stateless Address Autoconfiguration) and DHCPv6 is used, the M flag (Managed address configuration) is set to 0, indicating that addresses are not fully managed by DHCPv6, and the O flag (Other configuration) is set to 1, indicating that other configuration information is available via DHCPv6.

Question 3

What will the status of the A and L flags be in the RA-Prefix Information Option if a combination of SLAAC and DHCPv6 are being used?
A)0, 0
B)0, 1
C)1, 0
D)1, 1

Accepted Answer

The A flag is set to 1 if the address is autoconfigured, and the L flag is set to 1 if the address is DHCP-assigned. In this case, both SLAAC and DHCPv6 are being used, so both flags will be set to 1.

Question 4

How many bits are in a nibble?
A)2 bits
B)4 bits
C)16 bits
D)32 bits

Accepted Answer

A nibble consists of 4 bits. It is a unit of digital information that represents half a byte.

Question 5

One of the benefits of breaking down larger address prefix blocks into smaller blocks is for network prefix summarization in the routing tables.
Indicate the answer choice that best completes the statement or answers the question.

Accepted Answer

Breaking down larger address prefix blocks into smaller blocks allows for more efficient routing by enabling network prefix summarization, which reduces the size of routing tables and improves network performance.

Question 6

If the network is only configured for IPv4, then the IPv6 configuration on a client operating system doesn't provide any external or off-net IPv6 connectivity.

Accepted Answer

If the network is only configured for IPv4, it means the network infrastructure (routers, switches, etc.) and the internet service provided do not support IPv6 traffic. Therefore, even if a client operating system is configured to use IPv6, it cannot achieve IPv6 connectivity externally or off the local network because the network infrastructure does not support or route IPv6 packets.

Question 7

A nibble is 4 bits and there are 16 nibbles per hextet.

Accepted Answer

A hextet, being 16 bits, consists of 4 nibbles, not 16. Each nibble is 4 bits, so two nibbles make a byte (8 bits) and four nibbles make a hextet (16 bits).

Question 8

How many /60 networks can be assigned from a /48 network address prefix?
A)16
B)4096
C)65536
D)32768

Accepted Answer

A /48 network has 16 bits available for subnetting (since there are 64 bits in total for an IPv6 address and 48 are already used). Each /60 network uses 12 of those bits (60 - 48 = 12). Therefore, the number of /60 networks that can be created is 2^12 = 4096.

Question 9

Which of the following is true if a device has only an IPv6 link-local address?
A)IPv6 communication to the Internet is possible
B)only local IPv6 subnet communications are allowed
C)IPv6 communications to other subnets is possible but not to the Internet
D)no IPv6 communication is possible

Accepted Answer

Link-local addresses in IPv6 are used for communication within the same network segment or subnet. They are not routable beyond the local network, meaning the device cannot communicate with the Internet or other subnets using only a link-local address.

Question 10

What is true about the address 2001:db8:234:567::0/64?
A)it is an anycast address
B)it is a broadcast address
C)it is a valid IID
D)it is an invalid network prefix

Accepted Answer

The address 2001:db8:234:567::0/64 is a valid IPv6 address with an Interface Identifier (IID) of ::0 and a network prefix of 2001:db8:234:567. IPv6 does not use broadcast addresses and the address format does not indicate an anycast address. The network prefix is valid for IPv6.

Question 11

How many /64 networks can be assigned from a /48 network address prefix?
A)16
B)4096
C)65536
D)32768

Accepted Answer

A /48 network prefix allows for 16 additional bits to be used for subnetting, resulting in 2^16 = 65536 possible /64 networks.

Question 12

How many /64 networks can be assigned from a /60 network address prefix?
A)16
B)4096
C)65536
D)32768

Accepted Answer

A /60 network has 4 more bits than a /64 network (64 - 60 = 4). Each bit can represent 2 values (0 or 1), so 2^4 = 16.

Question 13

Where is IPv6 running on a device if the device is running at "wire speed?"
A)in an ASIC
B)in software
C)in flash memory
D)in the CPU

Accepted Answer

IPv6 running at "wire speed" implies that it is being processed very quickly, typically by specialized hardware designed for high-speed data processing. An Application-Specific Integrated Circuit (ASIC) is designed for this purpose, enabling fast processing of IPv6 packets without the overhead that software processing introduces. CPUs, while capable of processing IPv6, are not as efficient as ASICs for wire-speed operations. Flash memory is used for storage, not processing, and running IPv6 in software would not achieve wire speed due to the higher processing overhead.

Question 14

What will a Windows 7 Professional client do with an IPv6 temporary address after 24 hours?

Question 16

Infrastructure operating systems are those that generally run on client workstations.

Accepted Answer

Infrastructure operating systems are typically designed to run on servers and provide services to client devices, rather than running on client workstations themselves.

Question 17

Which of the following is a reason to break down larger prefix blocks into smaller blocks with respect to routing tables?
A)neighbor validation
B)larger subnets
C)larger routing tables
D)prefix summarization

Accepted Answer

Breaking down larger prefix blocks into smaller blocks allows for prefix summarization, which can simplify routing tables by aggregating multiple smaller networks into a single, larger summary route. This reduces the size of routing tables and improves routing efficiency.

Question 18

What will the status of the M and O flags be in the RA-ICMP field if a combination of SLAAC and DHCPv6 are being used?
A)0, 0
B)0, 1
C)1, 0
D)1, 1

Accepted Answer

When a combination of SLAAC (Stateless Address Autoconfiguration) and DHCPv6 is used, the M flag (Managed address configuration) is set to 0, indicating that addresses are not fully managed by DHCPv6, and the O flag (Other configuration) is set to 1, indicating that other configuration information is available via DHCPv6.

Question 19

Older infrastructure devices may not support IPv6 at all, and those will have to be replaced.

Accepted Answer

Many older infrastructure devices were designed and manufactured before the widespread adoption of IPv6, making them incompatible with IPv6 addresses and protocols. To support IPv6, these devices would need to be replaced with newer models that are designed to handle IPv6 traffic.

Question 20

What type of operating systems are generally found on switches, routers, and firewall?
A)server
B)client
C)network
D)infrastructure
