MCQ questions SUMMARY – still need Q5 and both SIM details

(Limit debug ppp authentication to 2 interfaces)

* ^9 O3 I5 U+ T" a; m5 x- vAnswer: 1476 (20 bytes IP + 4 bytes MINIMUM GRE header)

3- How to check MTU of interface using ping? / How can you check the links
% a* |7 N- h$ v  a! nmtu size with ping command?
A- ping 10.1.1.1 size 1501
B- ping 10.1.1.1 size 1500 df-bit
' {, s1 k4 T4 X; bC- ???
D- ???
# s. e0 V+ Y5 H: \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) (
* s5 u7 z0 T9 k! [Topology with a GRE tunnel and the outputs provided are show ip int brief and tunnel source and destination)
A- tunnel source int Eth0/0 is down
+ X$ D% h( O0 h0 |% t7 z- t( HB- no route from R1 to R3 loopback0 (tunnel destination)

# X0 E0 i) [0 ]  C" G
5- R1 and R2 OSPF neighbor. Which two statements are true? (choose two)
1 z4 `: _: T4 D' v7 n- A. G4 f(Output from show ip ospf neighbours on 2 routers, one of them shows FULL/DR, the
other FULL/-, you need to know how were they configured and will they exchange routes)
; N! P$ a& C6 R! CA- they are not neighs (wrong)
. S2 f! M. `+ I% Y6 VB- R1(non-DR) will not update its routes to R2
C- ???
D- ???
E- ???
Answer: B e ???
Note:
- }: F. z; D; m4 U4 g  _0 D@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.
@Hellboy: It’s a “select 2 out of 5” type of question and i selected that the router that
9 y; c6 j: L2 @$ Hshows as FULL/- is point to point and that the other router won’t send routing updates.

6- Two routers are connected through PPP connection. After the PPP was established
' w  r( t7 x& f3 k7 B8 d% |/ q3 Lthe admin put OSPF running above it. The OSPF formed adjacency but after soon the
* o1 d, m: I3 A$ A4 T0 `! Vadjacency dropped. What is the reason?
(The cause of OSPF forming an adjacency over a GRE tunnel and dropping immediately)
A- MTU mismatch
B- ospf routes contains the route to tunnel destination ( right)
4 Q9 f  ^  e" [% NC-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,
otherwise would cause Recursive Routing.
/ _: @* Z# C5 W  BD-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.
+ m1 C: X- S: l0 O0 A) Y4 x5 n7 rAnswer: D ???
someone suggested the following answer but it is not matching the uptions above:
( z3 R0 F; _, N3 q( X$ |5 KOSPF is configured on the tunnel , and the issue is bcoz the tunnel destination routes thru the tunnel

Tickets
8 S# i8 p) {& ?" t7 q* w6 ETicket – R1 – IP NAT
This ticket is different, the network 10.2.0.0 is in the NAT ACL list.
! g+ k0 h7 {! WThe fault is in router 1 and the cause is the serial that connects to the inside network
" h: p  j, [- m4 j& J( ~5 [6 ]is configured with “NAT outside”.
* @4 ^7 U# r& y* K0 K( sTo correct this fault is to configure “NAT inside”
. p! e8 X2 Y+ t: e- b3 v1 D
- H' O- e+ v, f! C- fTicket 11 – OSPF to EIGRP
OSPF->EIGRP under router eigrp 10 had to change to ospf_to_eigrp
