- What important factor differentiates Frame Relay from X.25?
A. Frame Relay supports multiple PVCs over a single WAN carrier connection.
B. Frame Relay is a cell-switching technology instead of a packet-switching technology
like X.25.
C. Frame Relay does not provide a committed information rate (CIR).
D. Frame Relay only requires a DTE on the provider side. - During a security assessment of a wireless network, Jim discovers that LEAP is in use on a
network using WPA. What recommendation should Jim make?
A. Continue to use LEAP. It provides better security than TKIP for WPA networks.
B. Use an alternate protocol like PEAP or EAP-TLS and implement WPA2 if supported.
C. Continue to use LEAP to avoid authentication issues, but move to WPA2.
D. Use an alternate protocol like PEAP or EAP-TLS, and implement Wired Equivalent
Privacy to avoid wireless security issues. - Ben has connected his laptop to his tablet PC using an 802.11g connection. What wireless
network mode has he used to connect these devices?
A. Infrastructure mode
B. Wired extension mode
C. Ad hoc mode
D. Stand-alone mode - Lauren’s and Nick’s PCs simultaneously send traffic by transmitting at the same time.
What network term describes the range of systems on a network that could be affected by
this same issue?
A. The subnet
B. The supernet
C. A collision domain
D. A broadcast domain - Sarah is manually reviewing a packet capture of TCP traffic and finds that a system is
setting the RST flag in the TCP packets it sends repeatedly during a short period of time.
What does this flag mean in the TCP packet header?
A. RST flags mean “Rest.” The server needs traffic to briefly pause.
B. RST flags mean “Relay-set.” The packets will be forwarded to the address set in the
packet.
C. RST flags mean “Resume Standard.” Communications will resume in their normal
format.
D. RST means “Reset.” The TCP session will be disconnected.
