201 BIG-IP Administrator
This exam is about network administrators, network operators, and network engineers a functional understanding of the BIG-IP system as it is commonly deployed in an application delivery network. The exam introduces students to the BIG-IP system, its configuration objects, how it processes traffic, and how typical administrative and operational activities are performed. The exam includes lecture, hands-on labs, interactive demonstrations, and discussions.

Set up, start/restart/stop, license, and provision the BIG-IP system out-of-the-box
Create a basic network configuration on the BIG-IP system including VLANs and self IPs
Use the Configuration utility and TMSH to manage BIG-IP resources such as virtual servers, pools, pool members, nodes, profiles, and monitors
Create, restore from, and manage BIG-IP archives
View resource status, availability, and statistical information and use this information to determine how the BIG-IP system is currently processing traffic
Use profiles to manipulate the way the BIG-IP system processes traffic through a virtual server
Perform basic troubleshooting and problem determination activities including using the iHealth diagnostic tool
Support, and view traffic flow using TCPDUMP
Understand and manage user roles and partitions
Configure and manage a sync-failover device group with more than two members
Configure stateful failover using connection mirroring and persistence mirroring
Getting started with the BIG-IP system
Traffic processing with BIG-IP Local Traffic Manager (LTM)
Using TMSH (TMOS Shell) command line interface
Using NATs and SNATs

Configuring high availability (including active/standby and connection and persistence mirroring)
Default admin/root accounts passwords are now expired by default on new installations. A discussion on this change of behavior is now available, and labs have been updated accordingly.
The Cookie persistence section and labs are no longer included in this exam. This content has been moved to the Configuring LTM curriculum.
A new chapter, Configuring and Managing a High Availability Environment (formerly in the Configuring LTM class) is now included in this exam.

B. The standby device also detects the failure and assumes the active role.
C. The active device will wait for all connections to terminate and then fail over.
D. The standby device will begin processing virtual servers that have failed, but the
active device will continue servicing the functional virtual servers.
Assuming that systems are synchronized, which action could take place if th eo
fv ae ir lcable is connected correctly and working properly, but the systems cannot
communicate over the network due to external network problems.
A. If network fail over is enabled, the standby system will assume the active
B. Whether or not network fail over is enabled, the standby system will stay in

Network application delivery and security specialist F5 Networks (NASDAQ:FFIV) will be reporting earnings tomorrow after market close. Here's what to expect.
Last quarter F5 Networks reported revenues of $702.6 million, up 4.17% year on year, in line with analyst expectations. It was a mixed quarter for the company, with revenue exceeding expectations, albeit by a small magnitude. Gross margin also improved. On the other hand, its underwhelming revenue guidance for the next quarter was disappointing (although next quarter's EPS guidance was in-line).
Is F5 Networks buy or sell heading into the earnings? Read our full analysis here, it's free.
This quarter analysts are expecting F5 Networks's revenue to grow 0.32% year on year to $702.3 million, slowing down from the 2.64% year-over-year increase in revenue the company had recorded in the same quarter last year. Adjusted earnings are expected to come in at $3.21 per share.
Majority of analysts covering the company have reconfirmed their estimates over the last thirty days, suggesting they are expecting the business to stay the course heading into the earnings. The company only missed Wall St's revenue estimates once over the last two years, and has on average exceeded top line expectations by 0.76%.
With F5 Networks being the first among its peers to report earnings this season, we don't have anywhere else to look at to get a hint at how this quarter will unravel for software stocks, but the segment has been facing declining investor sentiment following the fears around raising interest rates, with the stocks down on average 3.3% over the last month. F5 Networks is down 7.7% during the same time, and is heading into the earnings with an analyst price target of $168.15, compared to share price of $146.31.
One way to find opportunities in the market is to watch for generational shifts in the economy. Almost every company is slowly finding itself becoming a technology company and facing cybersecurity risks and as a result, the demand for cloud-native cybersecurity is skyrocketing. This company is leading a massive technological shift in the industry and with revenue growth of 70% year on year and best-in-class SaaS metrics it should definitely be on your radar.

We believe F5 stock (NASDAQ NDAQ : FFIV), an application security and cloud networking company, and Teleflex stock (NYSE: TFX), best known for its single-use medical products for common diagnostic and therapeutic procedures, will offer similar returns in the next three years. Although these companies are from different sectors, we compare them because they have a similar market capitalization of $9 billion - $10 billion. Also, both companies garnered a little under $3 billion in revenue and operating income of around $0.5 billion in the last twelve months. The decision to invest often comes down to finding the best stocks within the parameters of certain characteristics that suit an investment style. The size of profits can matter, as larger profits can imply greater market power. Since these stocks are from different sectors, comparing P/S against one another may not be helpful. We compare their current multiples with the historical ones in the sections below to better gauge their valuations.
Interestingly, TFX stock has had a Sharpe Ratio of 0.1 since early 2017, lower than 0.2 for FFIV and 0.5 for the S&P 500 Index over the same period. This compares with the Sharpe of 1.2 for the Trefis Reinforced Value portfolio. Sharpe is a measure of return per unit of risk, and high-performance portfolios can provide the best of both worlds.
Looking at stock returns, FFIV is up 12% this year, faring better than TFX, down 21%, and aligning with the broader S&P500 index, up 12%. There is more to the comparison, and in the sections below, we discuss the possible returns for F5 FFIV and Teleflex TFX in the next three years. We compare a slew of factors, such as historical revenue growth, returns, and valuation, in an interactive dashboard analysis of F5 vs. Teleflex: Which Stock Is A Better Bet? Parts of the analysis are summarized below.
1. F5’s Revenue Growth Is Better
2. Teleflex Is More Profitable
3. The Net of It All
While FFIV and TFX may offer similar returns in the next three years, it is helpful to see how F5’s Peers fare on metrics that matter. You will find other valuable comparisons for companies across industries at Peer Comparisons.

After the market closed Tuesday, F5 published results for the fourth quarter of its 2023 fiscal year -- which ended Sept. 30. Sales and earnings performance for the period came in ahead of market expectations and helped to send the software specialist's share price higher.
Why are investors excited about F5's Q4 results?
F5 reported non-GAAP (adjusted) earnings per share of $3.50 on sales of $706.97 million. For comparison, the average analyst estimate had called for per-share earnings of $3.21 on sales of roughly $702.25 million. F5's sales were up roughly 1% year over year in the quarter, and its adjusted earnings per share were up roughly 33.6% compared to the prior-year period.
The company delivered a significant performance beat on both the top and bottom lines. Management's forward guidance also seems to be pleasing investors.
What comes next for F5 stock?
For its next fiscal year, F5 is guiding for sales to come in somewhere between flat and a low-single-digit decline. While that might not sound like a particularly exciting projection, the company is facing caution from customers amid macroeconomic uncertainty -- and its earnings and stock buyback forecasts are more encouraging.
F5 expects to grow adjusted earnings per share somewhere between 5% and 7% on an annual basis. The company also plans to commit at least 50% of its annual free cash flow to repurchasing shares. As the company buys back stock, that will reduce its total number of shares outstanding. In turn, that should create positive catalysts for earnings per share in subsequent years. It may also signal that the company believes that its stock is undervalued at current prices.
