Which two statements are true about half-duplex and full-duplex communications? (Choose two.) Full duplex offers 100 percent potential use of the bandwidth. Full duplex allows both ends to transmit and receive simultaneously. Half duplex has only one channel. All modern NICs support both half-duplex and full-duplex communication. Full duplex increases the effective bandwidth.

. A standard ACL has been configured on a router to allow only clients from the 10.11.110.0/24 network to telnet or to ssh to the VTY lines of the router. Which command will correctly apply this ACL? access-group 11 in access-class 11 in access-list 11 in access-list 110 in

access-group 11 in

. a router learns of multiple toward the same destination. Which value in a routing table replesents the trustworthiness of learned routes and is used by the router to determine which route to install into the routing table for specific situation?

answer : metric

A security specialist designs an ACL to deny access to a web server from all sales staff. The sales staff are assigned addressing from the IPv6 subnet 2001:db8:48:2c::/64. The web server is assigned the address 2001:db8:48:1c::50/64. Configuring the WebFilter ACL on the LAN interface for the sales staff will require which three commands? (Choose three.) permit tcp any host 2001:db8:48:1c::50 eq 80 deny tcp host 2001:db8:48:1c::50 any eq 80 deny tcp any host 2001:db8:48:1c::50 eq 80 permit ipv6 any any deny ipv6 any any ip access-group WebFilter in ipv6 traffic-filter WebFilter in

deny tcp host 2001:db8:48:1c::50 any eq 80 deny tcp any host 2001:db8:48:1c::50 eq 80 deny ipv6 any any

level 1 parent route

. Refer to the exhibit. An ACL preventing FTP and HTTP access to the interval web server from all teaching assistants has been implemented in the Board Office. The address of the web server is 172.20.1.100 and all teaching assistants are assigned addresses in the 172.21.1.0/24 network. After implement the ACL, access to all servers is denied. What is the problem? inbound ACLs must be routed before they are processed the ACL is implicitly denying access to all the servers named ACLs requite the use of port numbers the ACL is applied to the interface using the wrong direction

named ACLs requite the use of port numbers
