An administrator is troubleshooting a time synchronization problem for the router time to another Cisco IOS XE-based device that has recently undergone hardening.
Which action resolves the issue?
- A . Allow NTP in the ingress ACL on 10.1.225.40 by permitting UDP destined to port 123.
- B . Ensure that he CPE router has a valid route to 10.1.255. 40 for NTP and rectify if not reachable.
- C . NTP service is disabled and must be enabled on 10.1.225.40.
- D . Allow NTP in the ingress ACL on 10.1.255.40 by permitting TCP destined to port 123.
How does an MPLS Layer 3 VPN function?
- A . set of sites use multiprotocol BGP at the customer site for aggregation
- B . multiple customer sites interconnect through service provider network to create secure tunnels between customer edge devices
- C . set of sites interconnect privately over the Internet for security
- D . multiple customer sites interconnect through a service provider network using customer edge to provider edge connectivity
D
Explanation:
A Multiprotocol Label Switching(MPLS) Layer 3 Virtual Private Network (VPN) consists of a set of sites that are interconnected by means of an MPLS provider core network. At each customer site, one or more customer edge (CE) routers attach to one or more provider edge (PE) routers.
