Drag and drop the credentials from the left onto the remote login information on the right to resolve a failed login attempt to vtys. Not all credentials are used
Answer:
Explanation:
Explanation
vty 0:
+ cisco
+ 0csic
vty 1:
+ no username
+ no password
The command "aaa authentication login default none" means no authentication is required when access to the device via Console/VTY/AUX so if one interface does not specify another login authentication method (via the "login authentication ..." command), it will allow to access without requiring username or password. In this case VTY 1 does not specify another authentication login method so it will use the default method (which is "none" in this case).
NEW QUESTION 71

- B. Customer traffic is encapsulated in a VPN label when it is forwarded in MPLS network.

NEW QUESTION 75
Which transport layer protocol is used to form LDP sessions?
- A. SCTP
- B. TCP
- C. RDP
- D. UDP
Answer: B
Explanation:
Explanation
LDP multicasts hello messages to a well-known UDP port (646) in order to discover neighbors. Once the discovery is accomplished, a TCP connection (port 646) is established and the LDP session begins. LDP keepalives ensure the health of the session. Thanks to the LDP session, LDP messages create the label mappings required for a FEC. Withdraw messages are used when FECs need to be torn down.
NEW QUESTION 76

- B. Route distinguishers make a unique VPNv4 address across the MPLS network.
- C. Route distinguishers allow multiple instances of a routing table to coexist within the edge router.
- D. Route distinguishers are used for label bindings.

A junior engineer updated a branch router configuration. Immediately after the change, the engineer receives calls from the help desk that branch personnel cannot reach any network destinations. Which configuration restores service and continues to block 10.1.1.100/32?
- A. ip prefix-list 102 seq 5 permit 0.0.0.0/32 le 32
- B. ip prefix-list 102 seq 15 permit 0.0.0.0/32 le 32
- C. route-map FILTER-IN permit 20
- D. route-map FILTER-IN deny 5
Answer: C
Explanation:
Explanation
By using "deny" keyword in a route-map, we can filter out the prefix specified in the prefix-list.
But there is an implicit "deny all" statement in the prefix-list so we must permit other prefixes with "permit" keyword in the route-map.

NEW QUESTION 83
Which list defines the contents of an MPLS label?
- A. 20-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
- B. 32-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
- C. 20-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
- D. 32-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
Answer: A
Explanation:
The first 20 bits constitute a label, which can have 2^20 values. Next comes 3 bit value called Traffic Class. It was formerly called as experimental (EXP) field. Now it has been renamed to Traffic Class (TC). This field is used for QoS related functions. Ingress router can classify the packet according to some criterion and assign a 3 bit value to this filed. If an incoming packet is marked with some IP Precedence or DSCP value and the ingress router may use such a field to assign an FEC to the packet. Next bit is Stack bit which is called bottom-of-stack bit. This field is used when more than one label is assigned to a packet, as in the case of MPLS VPNs or MPLS TE. Next byte is MPLS TTL field which serves the same purpose as that of IP TTL byte in the IP header

NEW QUESTION 87
Exhibit:
An engineer configured R2 and R5 as route reflectors and noticed that not all routes are sent to R1 to advertise to the eBGP peers. Which iBGP routers must be configured as route reflectors to advertise all routes to restore reachability across all networks?
- A. R2 and R5
- B. R1 and R4
- C. R4 and R5
- D. R1 and R5
Answer: C
Explanation:
When R2 & R5 are route reflectors (RRs), routes from R4 & R8 are advertised to R5 and R5 advertises to R2. But R2 would drop them as R2 is also a RR. Thereforesome routes are missing on R1 to advertise to eBGP peers.
Good reference: https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2015/pdf/TECRST-2310.pdf Route reflectors (RR) must be fully iBGP meshed so we cannot configure RR on both R1 and R5.
We should choose routers at the center of the topology RRs, in this case R4 & R5.
