Deck 2

Question 1

OSPF belongs in what plane?

What about IPV4 packets?

Answer 1

-Control
-Data

Question 2

How does a Cisco Unified Wireless Network respond to Wi-Fi channel overlap?

Answer 2

analyse client load/noise and dynamically assign channel

802.11 management frame that responds to request?

Answer 3

probe (responds to probe request)

This plane deals with routing protocols AND certain network request (ICMP request, etc)

Answer 4

Control plane

Question 5

All other areas in OSPF must connect to this area

Answer 5

Area 0

Question 6

OSPF default AD is?

-Routers take the OSPF route only in what conditions?

Answer 6

110

-no other routes with a lower AD than 110

Question 7

global unicast address range?

Answer 7

2000::/3-3fff

Question 8

….. is reserved for future use.
…. is currently the prefix used for ULAs.

Answer 8

-fc00::/8
-fd00::/8

Question 9

EUI-64 method for creating IPV6 addresses

Answer 9

1. Split MAC in half
2. place ff at end of first half and fe at beginning of second half
   3.flip seventh bit of first octet of MAC address
3. Add network address to beginning of all that

Question 10

Happens when a switch ALREADY know the MAC address (its in the table)

Answer 10

frame switching

Question 11

single IPV6 address that can be given to multiple clients to support redundancy and short path routing?

Answer 11

Anycast

Question 12

It serves as the centralized management point of an SDN architecture

Answer 12

A controller

Question 13

SSIDs are how many characters long at most?

Answer 13

32

Question 14

identifies interfaces on IPV6 devices and includes loopback and link-local addresses

Answer 14

Unicast

Question 15

address used exclusively by non-host devices

Answer 15

anycast

Question 16

Controlled-based/SDN uses disaggregation to separate?

Answer 16

control and data plane

Question 17

Controller-based/SDN networks do what specifically to the control plane?

Answer 17

-centralize it

Question 18

Prime example of intermittent network outages?

Answer 18

-Transceiver mismatches (using SFP-SR on one end and -LR on the other)

Question 19

Two characteristics of access layer in 3 tier networking?

Answer 19

-connect endpoint devices
-layer where APs are found

Question 20

BREAK IT DOWN. HAMMER TIME!

interface GigabitEthernet0/0.10 encapsulation dot1Q 3 ip address 10.10.2.10 255.255.254.0

Answer 20

-sub-interface created on G0/0 on ROUTER
-.10 corresponds to the .10 of the gateway address for inter-vlan routing (as is tradition)

Question 21

Quick way to find last usable for a network?

Answer 21

-take where last bit of octat of interest ends (ex: 11111100)
-in ex, octat ends in 4 spot
-means network address (ex: 192.168.1.0) increments by 4s
-if provided with addresses on exam already, subtract 2 from them to determine if it is divisible by where octat value ends. if it is, that answer is correct

Question 22

Defines private IP addressses and purpose is to ALLEVIATE IPV4 shortage

Answer 22

RFC 1918

Question 23

Address that is for experimental purposes in IPV6?

Also, both unique local and link local are non-routable. What defines link local from unique local?

Answer 23

-2001:db8::/32
-link local address (FE80) is created on EVERY IPV6 enabled link

Question 24

A log that has a BUNCH of CRC errors but no collisions means the following are bad, typically

Answer 24

-cables, transceivers, or switch ports

Question 25

Link Local address are NOT comparable to IPV4 private addresses you STUPID FUCK. What are?

Answer 25

unique local (FD00)

Question 26

Link local address are used a next hop address for what protocols? AND WHY?

Answer 26

-route adverts -ospf, eigrp, rip -conserve global addresses and because link locals usually stay the same

Question 27

an err-disabled state that occurs when a port rapidly go between up and down

Answer 27

link flapping

Question 28

two ports between switches need to have the same

Answer 28

speeds

Question 29

PAT is jus another way of saying

Answer 29

private IP addressing

Question 30

this aliases one name to another? this supports reverse name lookups? -This associates domain serial number with its owner?

Answer 30

-CNAME -PTR -SOA

Question 31

-correlates domain with its auth name serves -correlates host name with IP address

Answer 31

-NS -AAAA

Question 32

10GBASE-T (twisted pair) and CAT5e both support which speeds?

Answer 32

2.5 and 5 Gbps

Question 33

Cat3 speed? 1000Base-lx/lh speed? Cat5?

Answer 33

-10 mbps -1 Gbps -100 mbps

Question 34

characteristics of 1000Base-zx? characteristics of 1000Base-lx/lh?

Answer 34

-longer wavelength than lx/lh -single mode -up to 70km -multimode/single mode -up to 10km

Question 35

link local addresses are AUTOMATICALLY created. This differs from this type address that AUTOMATICALLY joins interfaces to it based on role/group

Answer 35

multicast
