MCQ questions SUMMARY – still need Q5 and both SIM details

(Limit debug ppp authentication to 2 interfaces)
+ `- {# I$ p9 H' d( r3 JA- debug condition interface range s0/1 -0/2

Answer: B (You have to use df-bit option on ping)

4- The tunnel between R1 and R3 is not coming up. Which two statements are true? (choose two) (

(Output from show ip ospf neighbours on 2 routers, one of them shows FULL/DR, the
' H! T+ z9 p+ Qother FULL/-, you need to know how were they configured and will they exchange routes)
. u3 j; V4 J1 T9 N5 zA- they are not neighs (wrong)

: D) N+ r. w) o4 x: O/ GNote:
  L! e  I5 g% F3 b0 _. @@Tamelir: This is the case when router has configured network that selects DR – broadcast,
NBMA, while the other’s network is p2p, p2mp or p2mp p2mp-nb WITH PRIORITY LARGER THAN THE FIRST ROUTER.
The routers WON’T EXCHANGE routes.
: U% T: ?8 a  Z2 O@Hellboy: It’s a “select 2 out of 5” type of question and i selected that the router that
shows as FULL/- is point to point and that the other router won’t send routing updates.
  t! V# e- @4 h3 Z, o0 T
8 o6 {, s( ^3 l; \# x  c6- Two routers are connected through PPP connection. After the PPP was established
- J/ Y9 P1 W7 y! k/ |- H1 y. D6 t* h! ^the admin put OSPF running above it. The OSPF formed adjacency but after soon the
adjacency dropped. What is the reason?
(The cause of OSPF forming an adjacency over a GRE tunnel and dropping immediately)
. W/ K, w4 m+ G" L/ Y) [, OA- MTU mismatch
B- ospf routes contains the route to tunnel destination ( right)
, L8 l1 i4 V) fC-Gre tunnel destination is not reachable through tunnel
>>> if this statement removes “not” then this would probably be the answer,
because the tunnel destination can not be through the tunnel itself,
$ f, C, U, D1 z9 w. @6 sotherwise would cause Recursive Routing.
7 d& W0 z2 a$ P  F$ J& j9 l. g6 cD-Gre tunnel ip address must be covered by network under “router ospf 1”
>>> The Tunnel IP subnet needs to be added to the routing process,
add network under router ospf x >>> So this one should be the right answer.
Answer: D ???
someone suggested the following answer but it is not matching the uptions above:
OSPF is configured on the tunnel , and the issue is bcoz the tunnel destination routes thru the tunnel

Tickets
3 j- ]6 V# c" m  Y9 ~Ticket – R1 – IP NAT
( e- A# j, g6 a+ w# {0 R' nThis ticket is different, the network 10.2.0.0 is in the NAT ACL list.
' ^) R$ _# x2 V3 TThe fault is in router 1 and the cause is the serial that connects to the inside network
% y* q0 X$ I- ~- P; K: `8 m! M. }is configured with “NAT outside”.
To correct this fault is to configure “NAT inside”

Ticket 11 – OSPF to EIGRP
OSPF->EIGRP under router eigrp 10 had to change to ospf_to_eigrp
