- Question
What are the decimal and hexadecimal equivalents for the binary number 10110111?
Options- A. 69/0x2102
- B. 183/B7
- C. 173/A6
- D. 83/0xC5
- Correct Answer
- 183/B7
ExplanationYou must be able to take a binary number and convert it into both decimal and hexadecimal. To convert to decimal, just add up the 1s using their values. The values that are turned on with the binary number of 10110111 are 128 + 32 + 16 + 4 + 2 + 1 = 183. To get the hexadecimal equivalent, you need to break the eight binary digits into nibbles (4 bits), 1011 and 0111. By add- ing up these values, you get 11 and 7. In hexadecimal, 11 is B, so the answer is 0xB7. - 1. Which of the following is an IEEE standard for frame tagging?

Correct Answer: 802.1Q
Explanation:
802.1Q was created to allow trunked links between disparate switches.
Correct Answer: show ip eigrp topology
Explanation:
Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure. You can see the topology table with the
show ip eigrp topology command.
Correct Answer: PPPoE
Explanation:
PPPoE encapsulates PPP frames in Ethernet frames and uses common PPP features like authentication, encryption, and compression. PPPoA is used for ATM.
Correct Answer: PAT
Explanation:
Port Address Translation (PAT) allows a one-to-many approach to network address translation.
Correct Answer: 2.4GHz
Explanation:
The IEEE 802.11b and IEEE 802.11g standards both run in the 2.4GHz RF range.
Correct Answer: A
Explanation:
Class A addressing provides 24 bits for host addressing.
Correct Answer: 12
Explanation:
The IEEE 802.11a standard provides up to 12 non-overlapping channels.
Correct Answer: 10.0.0.0
Explanation:
The network 10.0.0.0 cannot be placed in the next router's routing table because it already is at 15 hops. One more hop would make the route 16 hops, and that is not valid in RIP networking.
Correct Answer: (config-if)# ip access-group Blocksales in
Explanation:
Using a named access list just replaces the number used when applying the list to the router's interface.
ip access-group Blocksales in is correct.
Correct Answer: FF02::9
Explanation:
RIPng uses the multicast IPv6 address of
FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
