Where should an ACL be applied to control inbound traffic on an interface?

• On the inbound direction 

• On the outbound direction

• It does not matter

• Both inbound and outbound 

A network administrator needs to create an Extended ACL (number 103) with a precise policy for the 192.168.10.0/24 network:

1. Permit all users in that network to access the public web server at 172.17.80.1 (HTTP on port 80).

2. Deny those same users from using Telnet (port 23) to any destination.

Which set of access control entries (in the correct order) achieves this specific policy?

• 
  access-list 103 permit 192.168.10.0 0.0.0.255 host 172.17.80.1

  access-list 103 deny tcp 192.168.10.0 0.0.0.255 any eq telnet

• 
  access-list 103 deny tcp host 192.168.10.0 any eq 23

  access-list 103 permit tcp host 192.168.10.1 eq 80

• access-list 103 permit tcp 192.168.10.0 0.0.0.255 host 172.17.80.1 eq 80

  access-list 103 deny tcp 192.168.10.0 0.0.0.255 any eq 23 

• access-list 103 permit tcp 192.168.10.0 0.0.0.255 any eq 80

  access-list 103 deny tcp 192.168.10.0 0.0.0.255 any eq 23

A retailer has several hundred small stores that only generate low volumes of transaction data (credit card swipes). They want a low-cost, asymmetrical, and widely available connection to the headquarters' data center. Which Internet-Based Connectivity option is most likely used?

• Carrier Ethernet

• Frame Relay

• T1/E1 Leased Line

• Cable Broadband or DSL

The role of the Demarcation Point in a WAN is to:

• 
  Define the point where the customer's responsibility ends and the carrier's begins.

• Encrypt all data before transmission.

• Route packets across the carrier's network.

• Manage the local area network.

A large corporation has an internal network of 5,000 devices but only a single public IPv4 address assigned by its ISP. Which NAT technology is the most practical and economical solution for all devices to access the internet simultaneously?

• Static NAT

• Port Address Translation (PAT)

• Dynamic NAT with a pool of 5,000 addresses

• NAT64

What is one of the primary advantages of using NAT in a corporate network? 

• It simplifies routing protocols.

  internal IP addresses. 

• It allows for easier network segmentation. 

• It provides an additional layer of security by hiding

• It increases network traffic.

A regional chain of retail stores needs to connect its Point-of-Sale (POS) systems across hundreds of remote locations to a central server. The priority is low operating cost and rapid deployment. Which two connectivity types best meet these criteria?

• Satellite WAN

• Dedicated T1 Leased Lines

• ATM Circuits

• Cable Broadband

• DSL

Which command is used to create a named standard ACL on a Cisco router? 

• access-list 

• acl create

• ip acl

• ip access-list standard 

A company is closing its branch offices and moving all resources to a centralized cloud platform. The primary purpose of the WAN now shifts from connecting offices to connecting the company to the internet backbone. Which connectivity type is now the most critical?

• T1 Leased Lines

• Frame Relay

• ISDN

• High-speed Internet access (e.g., dedicated Ethernet/broadband)

In a scenario using Dynamic NAT with an address pool, a private host is idle for an extended period. The NAT entry is subsequently removed by the router. This removal is based on the router's:

• NAT Table Timeout (aging timer).

• CPU load.

• External ISP disconnection.

• ARP table refresh rate.
