**** There's six new MCQs****
Q1- Which command will limit debug output ppp authentication on serial 0/1 and serial 0/2? (Limit debug ppp authentication to 2 interfaces)
A- debug condition interface range s0/1 -0/2

B- debug condition interface s0/1 & 0/2
debug ppp authentication

9 Y0 o* t: N: |9 o: K. D/ t8 xQ2-What is the MTU’s size in a GRE tunnel? (Max size of GRE tunnel)
Answer: 1476 (20 bytes IP + 4 bytes MINIMUM GRE header)
———————————–
Q3-How to check MTU of interface using ping? / How can you check the links mtu size with ping command?
A- ping 10.1.1.1 size 1501
B- ping 10.1.1.1 size 1500 df-bit
: p  l! R. b% ~+ {2 bC- ???
D- ???
Answer: B (You have to use df-bit option on ping)

* u& a7 V- z' y# w% UQ4-The tunnel between R1 and R3 is not coming up. Which two statements are true? (choose two) (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
3 S3 ~) C  ^2 ]B-No route from R1 to R3 loopback0 (tunnel destination)
: G0 g% D+ r" V. F( [% Q: t+ PC- source and destination not in same subnet
D-???
3 \2 W! x4 [8 r' D; V, mAnswer: A, B
———————————–
Q5-R1 and R2 OSPF neighbor. Which two statements are true? (choose two)
(Output from show ip ospf neighbors 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)
. _" L$ f) P& J* bA- They are not neighbors (wrong)
* ], M9 N9 j) U& t% d- MB- R1(non-DR) will not update its routes to R2
C- Router R2 is configured with ospf point-to-point command (R2 is the router that shows as FULL/-)
0 z4 G8 F: c& a/ V0 u6 F" T7 YD- They need to be configured as OSPF NBMA
E- R2 should be configured as stub
Answer: B C
4 r* Q6 M/ S* ]. u& uNote:
) j  E3 `  ^, K- V0 x9 n9 {@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.
9 I" Q7 t# X- Q@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.
———————————–
Q6-Two routers are connected through PPP connection. After the PPP was established 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)
) J2 ]6 _5 L  D- {0 }* iA- MTU does not match
B- Area 0 need to exist for OSPF to function properly
C- Gre tunnel destination is not reachable through tunnel
2 z* h0 g8 }8 h9 pD- Gre tunnel ip address must be covered by network under “router ospf 1”
E- ospf routes contains the route to tunnel destination
! O- C# l) L5 [$ \3 ]) gAnswer: Not sure about the Answer but i think it's (C)
