Refer to the exhibit. Which two statements about the LISP implementation are true? (Choose two.)
A. 192.160 1.1 is used as the map-request source.
B. LISP ITR caches the IPv4 mapping data contained in a map-request message.
C. LISP ETR caches the IPv4 mapping data contained in a map-request message.
D. The address of the locator is used as the map-request source.
E. A LISP locator reachability algorithm is used.
Correction to my statement above. B is incorrect. C is correct. Just switch my B and C explanation. According to the link I provided, ETR is correct as far as caching not ITR. My bad.
The correct answers are A and B. See the below shown Link for verification.
(A) is correct but thats a typo in the answer. It should say 192.168. There is another identical question with the same exhibit and answer key but the address is correct in it.
(B) is correct based on the Configuring Optional LISP ITR/ETR (xTR) Functionality section Step 2 in the link shown below.
(C) is incorrect because….well because….lol
(D) is incorrect because the the locator address is a 10 address not 192. Therefore the default setting is not being used.
(E) is incorrect because the isp loc-reach-algorithm is not present in the Exhibit.
