The network operation team observes a traffic forwarding issue between R2 and R3:
✑ Ping and traceroute of loopback IP address from R2 to R3 is successful.
✑ iBGP peering in AS 65101 and AS 65201 is up.
Which configuration resolves the issue?
- A . Configure MD5 password authentication on R2.
- B . Advertise R2 and R3 loopback IPs in AS 65101 and AS 65201.
- C . Remove MD5 password authentication on R3.
- D . Set up eBGP multihop on R2 and R3 routers.
Refer to the exhibit.
Router R4 is configured correctly with default OSPF values. A network engineer configured R7 for OSPF. R7 must not be elected as a DR for the segment between R4-R7. The adjacency between R4 and R7 failed to form.
Which configuration resolves the issue?
- A . Option A
- B . Option B
- C . Option C
- D . Option D
Refer to the exhibit.

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 traffic class; 1-bit bottom stack; 8-bit TTL
- C . 20-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
- D . 32-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
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

An engineer applies a prefix-list filter that filters most of the network 10 prefixes instead of allowing them.
Which action resolves the issue?
- A . Modify the ip prefix-list EIGRP seq 10 permit 10.0.0.0/8 le 9 command.
- B . Modify the command Modify the Ip prefix-list EIGRP seq 10 permit 10.0.0.0/8 le 32 command.
- C . Modify the Ip prefix-list EIGRP seq 20 permit 0.0.0.0/0 le 32 command.

- C . Remove sequence 10 to add the PC source IP address and add it back as sequence 10.
- D . Remove sequence 20 for sequence 40 in the access list to allow Telnet.
