1. Refer to the exhibit. The network administrator needs to setup Switch1 for remote access from HostA. Theshow ip interface brief is issued on Router1 and the show interfaces trunk command is issued on theSwitch1 to verify the current status. The administrator applies the additional configuration shown in theexhibit to Switch1. However, the telnet from HostA fails. What additional commands need to be appliedto the switch?
Switch(config)# interface vlan 10
Switch(config-if)# ip address 10.1.1.250 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# ip default-gateway 10.1.10.254

2. Refer to the exhibit. On the basis of the configuration shown, how will an Ethernet frame on port GigabitEthernet0/1 be modified?
802.1Q encapsulation inserts a 4-byte tag field into the original Ethernet frame between the source address and type/length fields and recomputes the frame check sequence (FCS) on the modified frame.

CCNA 2 - Final Exam (B) 1. Refer to the exhibit. The output of the show ip route command for three routers on a network is displayed. All routers are operational, pings are not blocked on this network, and no default routes are installed. Which two pings will fail? (Choose two.)
from R1 to 192.168.3.1
from R3 to 192.168.1.1
2. A router that uses the RIP routing protocol has an entry for a network in the routing table. It then receives an update with another entry for the same destination network but with a lower hop count. What action will the router take for this new update?
It will append the update information to the routing table.

  ·8/8 stratus base 200 FT/AGL is observed at sunrise at an aerodrome in the north of France; the QNH is 1028 hPa and there is a variable wind of 3 kt. What change in these clouds is likely at 1200 UTC in summer and winter? WINTER: OVC. BASE 500 FT/AGL; SUMMER: SCT, BASE 3000 FT/AGL
  ·A blocking anticyclone in the northern hemisphere is: A WARM ANTICYCLONE/QUASI STATIONARY/SITUATED BETWEEN 50°N AND 70°N
  ·A Cb with thunderstorm has reached the mature stage. Which statement is correct?

• 'Drift down' is the procedure to be applied: AFTER ENGINE FAILURE IF THE AEROPLANE IS ABOVE THE ONE ENGINE OUT MAXIMUM ALTITUDE
  ·"Maximum endurance": IS ACHIEVED IN UNACCELERATED LEVEL FLIGHT WITH MINIMUM FUEL FLOW
  ·"Stepped climbs" are used on long-distance flights: TO FLY A PROFILE AS CLOSE AS POSSIBLE TO THE OPTIMUM ALTITUDE AS THE AEROPLANE MASS REDUCES
  ·A 'Balanced Field Length' is said to exist where:

CCNA 2 - Final Exam (A)
1. Refer to the exhibit. The network administrator issues the command no ip classless on Router1. What forwarding action will take place on a packet that is received by Router1 and is destined for host 192.168.0.26?
The packet will be dropped
2. Which three statements are true of holddown timers? (Choose three.)
prevent update messages from reinstating a route that may have gone bad
allow routers to still forward packets to destination networks that are in holddown
permit lower metric updates received from any neighboring router to reinstate the route to a possibly down Network
3. What command would the network administrator apply to a router that is running OSPF to advertise the entire range of addresses included in 172.16.0.0/19 in area 0?

-A category A aircraft can carry out an indirect approach followed by a visual manoeuvre only if the horizontal visibility is higher than or equal to : 1500 M
-A category B aircraft can carry out an indirect approach followed by a visual maneuver only if the horizontal visibility is higher than or equal to 1600 M
-A category C aircraft can carry out an indirect approach followed by a visual maneuver only if the horizontal visibility is higher than or equal to : 2400 M
-A category C aircraft can carry out an indirect approach followed by a visual maneuver only if the horizontal visibility is higher than or equal to : 2400 M
-A category D aircraft can carry out an indirect approach followed by a visual maneuver only if the horizontal visibility is higher than or equal to :3600 M

Atraso de propagação: tempo de viagem do sinal no meio de propagação, não depende da velocidade de transmissão (bps), d = comprimento do link físico, s = velocidade de propagação no meio (~200000 km/s). atraso de propagação = d/s, poucos microssegundos a centenas de milissegundos.
Intensidade de trafego: La/R, La = largura de banda e L tamanho do pacote. La/R~0 atraso pequeno. La/R <1: atraso se torna grande e La/R>=1: mais bits que a capacidade do link, crescimento exponencial do atraso.
Subsistemas de cabeamento estruturado: área de trabalho, rede secundaria, armário de telecomunicações, rede primária, sala de equipamentos, sala de entrada de telecomunicações e cabo de interligação externo.
Área de trabalho: cabeamento entre dispositivos e tomadas da parede (uma para cada 10m2), cada tomada deve possuir acessos de dados e voz e comprimento máximo do cabo = 5m.
