NEW QUESTION # 203
Refer to the exhibit.
An engineer must permit traffic from these networks and block all other traffic An informational log message should be triggered when traffic enters from these prefixes Which access list must be used?
- A. access-list acl_subnets permit ip 10.0.32.0 255.255.248.0 log
- B. access-list acl_subnets permit ip 10.0.32.0 0 0.0.255 log
- C. access-list acl_subnets permit ip 10.0.32.0 0.0.7.255 log
- D. access-list acl_subnets permit ip 10.0.32.0 0.0.7.255 access-list acl_subnets deny ip any log
Answer: C
Explanation:
The task is to create an access list that allows traffic from a specific range of networks while logging the traffic. The networks in question span from 10.0.32.0/24 to 10.0.39.0/24. To summarize these networks into a single entry, we use a subnet mask that encompasses all the individual /24 networks. The correct summary uses the wildcard mask 0.0.7.255, which corresponds to the subnet mask 255.255.248.0. This wildcard mask allows for all addresses from 10.0.32.0 to 10.0.39.255, which includes all the specified networks.

R1(config-router)#network 10.0.0.0 mask 255.0.0.0
R2(config)#router bgp 2
R2(config-router)#neighbor 192.168.10.1 remote-as 1
R2(config-router)#network 10.0.0.0 mask 255.0.0.0
Answer: A
Explanation:
With BGP, we must advertise the correct network and subnet mask in the "network" command ( in this case network 10.1.1.0/24 on R1 and network 10.2.2.0/24 on R2). BGP is very strict in the routing advertisements. In other words, BGP only advertises the network which exists exactly in the routing table. In this case, if you put the command "network x.x.0.0 mask 255.255.0.0" or
"network x.0.0.0 mask 255.0.0.0" or "network x.x.x.x mask 255.255.255.255" then BGP will not advertise anything.
It is easy to establish eBGP neighborship via the direct link. But let's see what are required when we want to establish eBGP neighborship via their loopback interfaces. We will need two commands:
+ The command "neighbor 10.1.1.1 ebgp-multihop 2" on R1 and "neighbor 10.2.2.2 ebgp- multihop 2" on R1. This command increases the TTL value to 2 so that BGP updates can reach the BGP neighbor which is two hops away.
+ A route to the neighbor loopback interface. For example: "ip route 10.2.2.0 255.255.255.0
192.168.10.2" on R1 and "ip route 10.1.1.0 255.255.255.0 192.168.10.1" on R2

- D. The 10.1.1.0/27 subnet is assigned as the inside local addresses.

Answer: C,D
Explanation:
Inside local address - An IP address that is assigned to a host on the inside network. 10.1.1.0/27 Inside global address - A legitimate IP address assigned by the NIC or service provider that represents one or more inside local IP addresses to the outside world. 209.165.201.0/27.

What is the result when a technician adds the monitor session 1 destination remote vlan 223 command1?
- A. An error is flagged for configuring two destinations.
- B. RSPAN traffic is split between VLANs 222 and 223.
- C. RSPAN traffic is sent to VLANs 222 and 223
- D. The RSPAN VLAN is replaced by VLAN 223.
Answer: D
Explanation:
When the command monitor session 1 destination remote vlan 223 is added to the configuration, it replaces the existing RSPAN VLAN destination with VLAN 223. This is because a monitor session can only have one remote VLAN destination at a time. If there was already a destination configured, such as VLAN 222 in this case, it would be overridden by the new command specifying VLAN 223.
