Click the Exhibit button.
Referring to the exhibit, the GRE tunnel between R-1 and R-2 allows connectivity between User-1 and Server-1. When User-1 communicates with Server-2 with packets that are 1472 bytes in size, no packet fragmentation occurs. User-1 can communicate with Server-1 with packets that are up to 1448 bytes in size with no packet fragmentation. However, if the packet size is larger than 1448 bytes, packet fragmentation occurs.
Why is the packet fragmentation occurring between User-1 and Server-1 in this scenario?
- A. The GRE header adds 24 bytes to the packet
- B. The IP header adds 20 bytes to the packet
- C. The IP header adds 24 bytes to the packet
- D. The GRE header adds 20 bytes to the packet

NEW QUESTION # 160
You are implementing traffic engineering in your MPLS network. You must ensure that the MPLS routes are used to traverse your network. Your solution should not affect IGP routes in your route tables.
In this scenario, which traffic engineering setting will accomplish this behavior?
- A. bgp-igp-both-ribs
- B. bgp
- C. bgp-igp
- D. mpls-forwarding
Answer: D
Explanation:
To ensure that MPLS traffic-engineered routes are used without affecting IGP routes in the route tables, the mpls-forwarding traffic engineering setting should be used. This setting allows MPLS to influence forwarding without changing the IGP route selection.References:

NEW QUESTION # 162
Exhibit
Routers R1 and R4 have a VRRP priority of 90, while R2 and R3 have default VRRP priorities Referring to the exhibit, which router will be elected as the primary VRRP router?
- A. R3
- B. R1
- C. R4
- D. R2
Answer: B
Explanation:
In VRRP (Virtual Router Redundancy Protocol), the router with the highest priority is elected as the master (primary) router. In the exhibit, routers R1 and R4 are both configured with a VRRP priority of 90. Since R2 and R3 have default priorities (which are lower than 90), they will not be elected over R1 or R4. Between R1 and R4, if all else is equal, the router with the numerically higher IP address becomes the master. However, if not enough information is provided to determine which of R1 or R4 has the higher IP address, the answer would be the one explicitly mentioned with the highest priority.

NEW QUESTION # 170
Exhibit
You configured interface ge-0/070.0 to run IS-IS. but this interface does not appear in the output of the show isis adjacency command as shown in the exhibit.
What is the problem in this scenario?
- A. The family iso statement must be added to the logical interface.
- B. The router at the other end of the link is a Level 1 only router.
- C. The router at the other end of the link Is not sending any IS-IS Hello messages.
- D. This is a Gigabit Ethernet interface, that is incompatible with the reference-bandwidth 100g statement.
Answer: A
Explanation:
For IS-IS to form adjacencies, the 'family iso' statement must be configured on the interface. This is required because IS-IS operates over the connectionless network service (CLNS) and not over IP. Without the 'family iso' configuration, IS-IS cannot form adjacencies over the interface.
